Introduction
Global Glass Handbook 2011 – Architectural Products
www.pilkington.com8
Our Glass Handbook is an easy-to-use reference document provid-ing consistent information on our global range of architectural prod-ucts worldwide.
We have tried to highlight the benefits of the product as well as the technical specifications to the user.
This handbook covers the global range of products as it applied in March 2011; changes to the product range since then have not been incorporated. Although presented in this handbook, some of the prod-ucts will not be available in all markets. Our publication is also not exhaustive, and therefore does not cover all products, combinations and applications. For additional information or advice, please get in contact with your local Pilkington representatives or for the latest information, visit our website at www.pilkington.com/products/bp/.
Guide for Use:Our Glass Handbook is organised into benefit-led categories. Please note that some of our products have multiple benefits and therefore may be found in more than one benefit-led categories. If you are searching for a solution to a particular problem, you may need to consider products in more than one category.

General description
Global Glass Handbook 2011 – Architectural Products 9
Visible Light
Light Transmittance (LT) or Visible Transmittance (VLT) is the proportion of visible light at near normal incidence that is transmit-ted through the glass.
Light Reflectance (LR) is the proportion of visible light at near normal incidence that is reflected by the glass.
Colour Rendering Index (Ra) expresses the colour rendering pro-perties of glass in transmission.
Solar Energy
Glass manages solar radiation from the sun by three mechanisms: transmittance, reflectance and absorptance, which for solar control purposes are defined in terms of the following parameters:
Direct Solar Energy Transmittance (ET) is the proportion of solar radiation at near normal incidence that is transmitted directly through the glass.
Solar Energy Reflectance (ER) is the proportion of solar radiation at near normal incidence that is reflected by the glass back into the athmosphere.
Solar Energy Absorptance (EA) is the proportion of solar radia-tion at near normal incidence that is absorbed by the glass.
Total Solar Energy Transmittance (TET) or Solar Heat Gain Coefficient (SHGC), also known as g value or solar factor, is the fraction of solar radiation at near normal incidence that is transferred through the glazing by all means. It is composed of the direct trans-mittance, also known as the short wave component, and the part of the absorptance dissipated inwards by longwave radiation and con-vection, known as the longwave component. The proportions of the absorbed energy that are dissipated either inside or outside depend on the glazing configuration and the external exposure conditions.
Selectivity index S: light to heat ratio (S = LT / TET) or (S = LT / SHGC).
Performance data
www.pilkington.com10
The solar control mechanism is illustrated in Figure 0.1.
The solar radiant heat admission properties of glasses can be com-pared by their shading coefficients.
The Total Shading Coefficient (TSC) is derived by comparing the properties of any glass with a clear float glass having a total energy transmittance of 0,87 (such a glass would have a thickness of about 3 mm). It comprises a short wavelength and long wave-length shading coefficient. In certain instances, it is simply referred to as Shading Coefficient.
The Short Wavelength Shading Coefficient (SWSC) is the direct energy transmittance divided by 0,87.
The Long Wavelength Shading Coefficient (LWSC) is the frac-tion of the absorptance released inwards, again divided by 0,87.

Performance data
Thermal Insulation
Heat loss is quantified by the thermal transmittance or U value (U). The U value, usually expressed in S.I. units (Système Internationale d’Unités) of W/m²K, is the heat flux density through a given struc-ture divided by the difference in environmental temperatures on either side of the structure in steady state conditions. It is more ge-nerally referred to as the rate of loss of heat per square metre, under steady state conditions, for a temperature difference of one Kelvin (or degree Celsius) between the inner and outer environments sepa-rated by the glass, or other building element.
The Summer U value and Winter U value (also known as U-Factor) are calculated using LBNL Windows 5.2. The Summer U value is based on an outdoor temperature of 90°F (32°C), an indoor tempera-ture of 75°F (24°C), a solar intensity of 248 Btu/hr ft2 °F (783 W/m2) and a 6,3 mph (2,8 m/s) wind velocity. This is referred to as NFRC 100-2001 Summer. The Winter U value is based on an outdoor tem-perature of 0°F (–18°C), an indoor temperature of 70°F (21°C) and a 12,3 mph (5,5 m/s) wind velocity with no sun. This is referred to as NFRC 100-2001 Winter.

Coating process
There are two different coating technologies used to manufacture high performance glass: on-line and off-line coatings.
On-line coatings are applied during manufacture. Generally speak-ing, on-line coated products offer lower performance levels than off-line coated products. However, they have a range of other benefits; they are easier to handle and process, and can be toughened or lami-nated without difficulty. They are also far more durable and achieve a higher degree of passive solar heat gain (g value, the proportion of solar radiation transmitted through the glass by all means) which is particularly beneficial in cool but sunny conditions.
Off-line coatings are applied after manufacture. Most off-line coated products are able to give higher performance levels, but they do require extra care in handling and processing. We can supply them in toughened and laminated form by applying the coating to pre-proc-essed glass. Some of them can also be provided in toughenable form.

1. Solar Control

www.pilkington.com16
Solar Control
Solar control is a key issue in terms of energy saving. In hot condi-tions or for buildings with high internal loads, solar control glass is used to minimise solar heat gain by rejecting solar radiation and help control glare. In more temperate conditions, it can be used to balance solar control with high levels of natural light.
The topic of air-conditioning is becoming a major concern to build-ing designers and architects. Often, more energy is used to operate air-conditioning systems during the summer months than to heat the building in winter thereby increasing the carbon footprint. It is there-fore essential to improve the energy efficiency of buildings during the summer as well as the winter.
During the winter, low-emissivity glass can reduce heat loss while allowing high levels of valuable free solar gain to heat buildings with no significant loss in natural light. However, unless combined with solar control glass, in the summer it can become uncomfort-ably hot. The correct choice of glass can help to reduce the capital outlay, running costs and associated carbon emissions of a building throughout the year.
No te: The potential for solar control glass to cut CO2 emissions from buildings has been analysed by the Dutch scientific institute TNO in a study undertaken for Glass For Europe. The study concludes that between 15 and 80 million tonnes of CO2 emissions annually – roughly between 5% and 25% of the EU’s target – could be saved by the year 2020 by optimal use of solar control glass. Reference: “Impact of Solar Control Glazing on energy and CO2 savings in Europe” (TNO Report 2007-D-R0576/B by TNO Built Environment and Geosciences, Delft, The Netherlands). www.glassforeurope.com.
Given the variety of building designs and climatic conditions and the different levels of exposure to solar radiation during the year, the choice of glass must be able to protect the inside of the building to ensure maximum comfort, minimise energy consumption, guar-antee safety and, not least, provide the optical and aesthetic quali-ties that satisfy the designer.

Solar Control
We are continually innovating and developing products that satisfy the full range of architectural requirements. Over the years we have developed a wide range of energy management solutions for large and small glazed areas on all types of building.
Our innovative solar control products cover the whole range:l from the highest performing, off-line coated, solar control and
low-emissivity products within the Pilkington Suncool™ range;l through on-line environmental control glasses that combine
good performance solar control with low-emissivity such as Pilkington Eclipse Advantage™ and Pilkington Solar-E™;
l to medium performance reflective glasses such as Pilkington Eclipse™ Gold, Pilkington SunShade™ Silver, Pilkington Reflite™ and high performance tinted glasses such as Pilkington Arctic Blue™;
l to low-performance, body-tinted glass in the Pilkington Optifloat™ Tint range;
l and even to solar control glass combined with the revolutionary self-cleaning Pilkington Activ™.
In addition to the above ranges, our solar control products can be used with many other Pilkington solutions, to achieve countless benefits in terms of safety, functionality and cost-efficiency.
How it works – Glass manages solar heat radiation by three mecha-nisms: transmittance, reflectance and absorptance, which for solar control purposes are defined in terms of the following parameters:l Direct transmittance – the proportion of solar radiation trans-
mitted directly through the glass.l Reflectance – the proportion of solar radiation reflected back into
the atmosphere.l Absorptance – the proportion of solar radiation absorbed by the
glass.l Total transmittance (also known as g value, solar factor, or
SHGC) – the proportion of solar radiation transmitted through the glass by all means. This is composed of the direct transmittance and that which is absorbed by the glass and re-radiated inwards.

Solar Control
Further parameters given to glass are as follows:l Light transmittance or Visible Light Transmittance – the pro-
portion of the light that is transmitted by the glass.l Light reflectance – the proportion of the light that is reflected by
the glass.l Total shading coefficient or Shading Coefficient – the ratio
between total solar heat transmittance of the glass and that of a single 3 mm thick clear float glass.
l Shortwave shading coefficient
SWSC = ET
total solar heat transmittance of standard 3 mm glass
l Longwave shading coefficientLWSC = TSC – SWSC
l Total shading coefficient
TSC = TET (or SHGC)
total solar heat transmittance of standard 3 mm glass
where: SWSC – shortwave shading coefficient LWSC – longwave shading coefficient TSC – total shading coefficient ET – direct solar heat transmittance TET – total solar heat transmittance SHGC – Solar Heat Gain Coefficient
Example for Pilkington Optifloat™ Green 6 mm glass:
TSC = 0,59
= 0,680,87

Thermal breakageDue to their high solar heat absorptance, some glasses may be sub-ject to thermal breakage. The risk of thermal breakage may occur on façades exposed to the sun, and in situations where high tem-perature differences across the glass pane are expected. In such cases it is advisable to specify toughened or heat strengthened glass. A thermal safety check is advisable for all applications.

Pilkington Optifloat™ Tint
Body-tinted solar control glasses
DescriptionPilkington Optifloat™ Tint is a range of low solar control perform-ance uncoated body-tinted glasses, with low light reflection and high energy absorption.
Please note that in all body-tinted glass products, the properties and colour density vary with the thickness; this needs to be considered when designing façades where colour uniformity is aesthetically important. All of the body-tinted glasses can be toughened or lami-nated and/or incorporated into insulating glass units.
ApplicationsPilkington Optifloat™ Tint glass products can be used wherever a coloured glass without surface coating is required for visual appeal or where a degree of solar control performance is neces-sary to improve or control the internal environment of the building. Where a safety glass is required, they can be specified as tough-ened or laminated glass.
Designed to improve conditions within buildings by reducing glare, solar radiation and heat transfer into the building, they also reduce UV radiation and offer improved privacy, when compared with clear glass.

Pilkington EverGreen™
Pilkington Emerald Green™
High performance body-tinted solar control glasses
DescriptionPilkington EverGreen™ and Pilkington Emerald Green™ estab-lish new standards of quality, aesthetics and performance for green body-tinted glass. These products offer solar control characteristics and high selectiv-ity, in two different shades of green.
Pilkington EverGreen™ provides high light transmittance (66% in 6 mm) whilst still providing solar control, resulting in a high selec-tive glass.Pilkington Emerald Green™ provides comparatively lower light transmittance (51% in 6 mm) with solar control, resulting in a glass with a good selectivity index.
The solar control properties and colour densities of both products vary with each thickness, so that glass with properties appropriate to a particular application can be chosen.
ApplicationsPilkington EverGreen™ and Pilkington Emerald Green™ are ideally suited to both hot and cold climates. These products absorb much of the sun’s heat and UV rays while still letting through a high level of daylight. Where a safety glass is required, they can be specified as toughened or laminated glass.

Pilkington SuperGrey™
Pilkington Dark Grey™
High performance body tinted solar control glasses
DescriptionPilkington SuperGrey™ and Pilkington Dark Grey™ are low-reflective body-tinted glasses which offer dramatic, deep cool-grey appearance, increasing visual privacy and dramatically reducing read-through from interior shading devices.
Pilkington SuperGrey™ combines stunning exterior aesthetics and unsurpassed interior glare control with the best solar control performance of any tinted float glass in the industry.In a different shade of grey, Pilkington Dark Grey™ offers higher light transmission whilst providing solar control performance. Both products soften bright daylight and reduce glare, making them per-fect for applications near computers and video display screens.
Applications Pilkington SuperGrey™ and Pilkington Dark Grey™ are ideal where architectural designs or restrictions prohibit structures with high reflectance. Common applications include low, mid and hi-rise buildings, such as hospitals, educational institutions, offices and retail skylight applications. Where a safety glass is required, they can be specified as toughened or laminated glass.
www.pilkington.com40
Pilkington SuperGrey™
Pilkington Dark Grey™
Features and benefitsl Uncoated glasses which provide the performance of reflective glass.l Enhanced visual privacy and reduced read-through from interior
shading devices.l Pilkington SuperGrey™ is the best solar control of any uncoated
glass, providing the lowest shading coefficient of any float glass and a better shading coefficient than many reflective glasses.
l Unsurpassed light and glare control, improving visual privacy and reducing the need for blinds or shades.
l Distinctive aesthetics inside and outside, offering a deep, cool-grey tint from the exterior, while providing a remarkably crisp, comfortable view from the interior as they offer a neutral colour from the inside.
l Uniform, no read-through look between spandrel and vision glass areas eliminating the need for an opacifier in the spandrel glass.
l Pilkington SuperGrey™ offers low UV transmittance, signifi-cantly outperforming other tinted and coated glass products (in 6 mm it blocks 99% of the sun’s damaging UV rays).
l Additional thermal insulation performance when combined in an insulating glass unit with a low-emissivity glass.
l Can be laminated, toughened, bent and enamelled using standard techniques.
l Can be used in monolithic form or incorporated in insulating glass units.
l Available in 5 mm and 6 mm thicknesses.

Pilkington Solar-E™
Pyrolytic on-line coated solar control glasses with low-emissivity properties
DescriptionPilkington Solar-E™ is a range of good solar control performance on-line coated glasses with low SHGC, low reflectivity, reduced glare and low-emissivity. The products are available in a range of colours – Clear, Blue-Green, EverGreen, Grey and Arctic Blue.
Application Pilkington Solar-E™ products can be used in single glazing appli-cations provided that the coating faces the interior of the building. They provide attractive solutions to various applications where good light transmittance with enhanced solar control performance is required. Thanks to their low exterior light reflectance the products are widely used for modern glass façades where high reflectance is prohibited or undesirable. Where a safety glass is required,the prod-ucts can be specified as toughened or laminated glass.
Features and benefitsl Good solar control performance with low-emissivity, reducing
the need for heating and cooling the building.l Medium light transmittance and low light reflectance for undis-
torted, natural views.l Available in a range of colours (Clear, Blue-Green, EverGreen,
Grey, Arctic Blue).l Further improved thermal insulation performance when com-
bined in an insulating glass unit with a low-emissivity glass.l Can be laminated, toughened, bent and enamelled using standard
techniques.l Can be used in monolithic form or incorporated in insulating
glass units.l Colour stability whether toughened or annealed.l Achieves Class B to EN 1096 for coated glass.l Achieves ASTM C 1376 standard specification.l All colours available in 6 mm and in 8 mm thicknesses.

Pilkington Suncool™
Superior off-line coated solar control performance glasses with outstanding thermal insulation
DescriptionPilkington Suncool™ is a range of superior solar control perform-ance off-line coated glasses, with high light transmittance and low, medium or high light reflectance. Due to their very low-emissivity coating, the products also offer outstanding thermal insulation. The wide range of products is available in clear or neutral appea-rance and in two distinctive colours, blue and silver.
All products from the Pilkington Suncool™ range are available in com-bination with self-cleaning properties, Pilkington Activ Suncool™, as well as they are available on low-iron substrate, Pilkington Suncool™ OW, to maximise light transmittance and reduce the risk of thermal breakage.
For additional thermal insulation, Pilkington Suncool™ insulating glass units can be filled with an inert gas such as argon.
Table 1 .1 . The appearance of the Pilkington Suncool™ product range.
* Level of reflection: low < 15%, medium 15-25%, high > 25%.

Pilkington Suncool™
ApplicationsPilkington Suncool™ products can only be used in insulating glass units. Designed to achieve optimum performance in large glazed areas, Pilkington Suncool™ products are suitable for commercial and residential applications that demand high light transmission properties. The high selectivity index (light-to-heat ratio) combined with outstanding thermal insulation makes the range ideally suited to large areas of glazing, where the need is to control solar gains without significantly reducing the internal light levels. Where a safety glass is required, the products can be specified as toughened or laminated glass.
Benefitsl Superior solar control performance with the highest level of ther-
mal insulation (U value down to 1,0 W/m2K in a double insu-lating glass unit with 90% argon filled), reducing the need for cooling and heating the building.
l High selectivity index (light transmittance divided by total solar heat transmittance), offering low solar gains without significantly reducing the internal light levels.
l Wide choice of colours and appearances, providing solutions for the most demanding designs.
l Range of light transmission and reflection.l Pilkington Activ Suncool™ available, reducing the need for man-
ual cleaning as well as providing high performance solar control and low-emissivity.
l Pilkington Suncool™ OW (on Pilkington Optiwhite™ low-iron substrate) available to maximise light transmittance and reduce the risk of thermal breakage.
l Can be enhanced when combined with other Pilkington products to provide additional benefits such as noise control, safety or security properties.
l Harmonising spandrel panels available, allowing freedom in design of complete glass façades.
l Can only be used in insulating glass units; gas filling (e.g. argon) can be used to achieve higher thermal insulation.
l Available in annealed, toughened or toughenable form (depend-ing on the product) – all products available in laminated form.
l Available in 6 mm, 8 mm and 10 mm thickness in annealed and toughened form (4 mm available in some products, 12 mm may be available on special request).

Thermal Insulation
Low-emissivity
Advances in low-emissivity (low-e) glass technology have made windows an essential contributor to energy conservation and com-fort, minimising heat loss and internal condensation.The measure of heat flow is usually expressed in terms of U value (or U-factor), which is the rate of heat flow in Watts per square metre per degree Kelvin temperature difference between inside and outside (expressed as W/m²K). The lower the U value, the better the insulation of the product.
How it works – Effectively, low-emissivity glass will reflect energy back into a building, to achieve much lower heat loss than ordinary float glass. Additionally, different types of low-emissivity glass allow different amounts of free energy from the sun, passive solar heat gain, helping to reduce heating requirements and costs, espe-cially in colder months.

Global Glass Handbook 2011 – Architectural Products
Thermal Insulation
In hot weather conditions, low-e glass should be combined with solar control glass in an insulating glass unit to enhance the performance, by reducing: – heat gain from direct solar radiation into the building due to the lower g value, and – conduction gains through the insulating glass unit from the hot outside environment to the air-conditioned inside
The combination of solar control and low-e in an insulating glass unit can help to reduce air-conditioning loads, save energy and reduce CO2 emissions.

Thermal Insulation
Note: The potential for low-e glass (double and triple glazing) to cut CO2 emissions from new and existing buildings has been analysed by the Dutch scientific institute TNO in a study undertaken for Glass For Europe. Up to 90 million tonnes of CO2 emissions could be saved annu-ally by 2020 if all Europe’s buildings (existing and new residential and non-residential buildings) were fitted with double-glazed low-e insula-ting glass units. An additional 7 million tonnes of CO2 emissions could be cut thanks to the greater use of triple-glazed low-e insulating glass units for new buildings, where appropriate. Reference: “Potential impact of Low-Emissivity Glazing on energy and CO2 savings in Europe” (TNO Report 2008-DR1240/B by TNO Built Environment and Geosciences, Delft, The Netherlands). www.glassforeurope.com.
To maximise energy efficiency all year round and in all climates, often the ideal glazing solution balances both solar control and low-emissivity performance. Our products offer two ways in which this can be achieved:l by using a single glass which provides both solar control and
low-emissivity on one pane of the insulating glass unit,l by using both a solar control glass and a separate low-emissivity
glass within the insulating glass unit.
The ability to do this gives us great flexibility to meet energy mana-gement criteria.
Our low-emissivity range covers all levels of requirements:l from on-line products such as Pilkington Energy Advantage™
and Pilkington K Glass™,l to extremely low U value off-line solutions in the
Pilkington Optitherm™ range,l through to Pilkington Suncool™, Pilkington Solar-E™ and
Pilkington Eclipse Advantage™ which provide both low-emissi-vity and solar control properties in a single product.

Pilkington Optitherm™
Off-line coated high performance low-emissivity glass
DescriptionPilkington Optitherm™ is a range of high performance off-line coated low-emissivity glasses, offering high to very high thermal insulation performance as well as neutrality. The effect of the low-emissivity coating is to reflect the long wavelength energy (generated by heating systems, lighting and building occupants) back into the building. However, the transparent coating still permits the trans-mission of short wavelength energy originating from the sun. This solar energy is absorbed by the internal surfaces of the building and re-radiated at the longer wavelengths that are then reflected by the coating into the building. Pilkington Optitherm™ range of products has a very similar visual appearance to that of ordinary clear glass. As their coating is transparent and neutral in colour, its effect on light transmission and reflection is barely perceptible.
Pilkington Optitherm™ S3 is one of the market leading super neu-tral low-emissivity glass; due to its very high light transmittance and low light reflectance, it has high level of neutrality, making it ideal for large glazing areas with demanding design. For safety applications, we offer Pilkington Optitherm™ S3 Pro T which should be toughened and is colour matched to Pilkington Optitherm™ S3 after toughening.
Pilkington Optitherm™ S3 is available in combination with Pilkington Optilam™, Pilkington Optiphon™ or Pilkington Activ™ to offer additional benefits such as impact resistance, increased secu-rity, improved noise reduction or additional self-cleaning properties.
For applications requiring a U value of 1,0 W/m2K, we offer Pilkington Optitherm™ S1. Despite its low U value, this product still offers outstanding performance in terms of light transmission and colour neutrality. Pilkington Optitherm™ S1 is the ultimate in thermal insulation for insulating glass units; it should be specified for any situation where excessive heat loss is a concern. It is ava-ilable in combination with Pilkington Optilam™ for impact resi-stance and increased security or with Pilkington Optiphon™ for improved noise reduction.
Developed specifically for energy-optimised triple glazing, Pilkington Optitherm™ GS maximises solar energy gain and
www.pilkington.com106
Pilkington Optitherm™
reduces heat loss to increase the energy efficiency of houses. Pilkington Optitherm™ GS exceeds the criteria for Passiv Haus glazing, achieving a total solar energy transmittance (g value) of up to 63% whilst still attaining a U value of as low as 0,6 W/m2K. It is available in combination with Pilkington Optilam™ for impact resistance and increased security or with Pilkington Optiphon™ for improved noise reduction.
ApplicationsPilkington Optitherm™ range of glasses can only be used in insu-lating glass units. They can be used from the smallest installation to the most prestigious curtain walling applications – anywhere where there is concern for reduced energy consumption and heat loss. They are often used in combination with other environmental control glas-ses. Pilkington Optitherm™ GS has been specially designed for triple glazed units to meet and exceed Passiv Haus specifications.
Features and benefitsl High to very high thermal insulation performance with U values

Pilkington Spacia™
On-line coated low-emissivity vacuum glazed extra thin insulating glass unit
DescriptionPilkington Spacia™ is the world’s first commercially available vacuum glazing. It offers the thermal performance of conventio-nal double glazing in the same thickness as single glass (6 mm). Pilkington Spacia™ provides a real solution to the problems of balancing historical preservation with modern comfort and environ-mental requirements.
Application Pilkington Spacia™ has low overall thickness (6 mm) and good acoustic performance making it ideal for use in historic buildings, offering replacement windows more in keeping with the original design. It may even allow the use of the original frames if these are in a reasonable or repairable condition. Until now, the only choices were to sacrifice thermal performance and comfort, or to compro-mise the appearance of the building by using bulkier modern frames with double glazing. Pilkington Spacia™ is also suitable for other applications where the use of thinner, low-weight glazing is desi-rable, for example in sliding box sashes, secondary glazing, or as one pane of a triple glazed “super-window”.
How it worksConventional double glazing consists of two glass panes placed up to 20 mm apart, with the cavity between the panes filled with either dry air or an inert gas such as argon or krypton. This gas reduces heat transfer through the glass due to its lower thermal conductivity. The wider the gap between the panes, the lower the heat transfer, up to an optimum level above which circulation patterns in the gas reduce the benefit. This means that the overall thickness of thermal-ly-efficient double glazing is typically 24 mm. Double glazing with a krypton-filled cavity as low as 4 mm is technically possible, but it is difficult to ensure that such units are sufficiently stable and gas tight to maintain their integrity to keep acceptable levels of thermal performance over the desired life of the glazing.
Pilkington Spacia™ is different; the air between the two panes of glass is extracted, creating a vacuum. A vacuum, even a small one, is much more effective at minimising conduction and convection
111

Global Glass Handbook 2011 – Architectural Products
heat losses, so the gap between the two panes can be reduced to just 0,2 mm, giving an overall thickness of just over 6 mm. Heat flow through radiation is limited through one of the glass panes having a low-emissivity coating, similar to that used in modern conventional double glazing. Pilkington Spacia™ offers the same thermal perfor-mance as conventional double glazing in one quarter of the thickness and two thirds of the weight.

(1) Protection capThe vacuum creation process in Pilkington Spacia™ results in a hole in the inner pane, which is sealed afterwards. This seal is covered by a small permanent plastic black cap (12 mm diameter), which is located 50 mm from the glass edge. It must remain on the glass surface after glazing and should be glazed towards the inside of the building. The cap can be positioned in any corner of the pane.(2) Microspacers With an individual diameter of only 0,5 mm, the microspacers (20 mm apart) ensure that the two glass panes are kept a fixed distance apart.

Fire Protection
The wide range of modern functional glazings now available has opened up remarkable scope for creative design in today’s architec-ture. Transparent design from façades and roofs right through to the core of the building is no longer a vision, it is a reality.
State-of-the-art glazing can now be used in high performance designs to provide a protected, yet comfortable and versatile building envi-ronment, founded on daylighting, brightness and clear vision, repla-cing solid roofs, doors and partitions which block out views and natural light. Our fire-resistant glasses, Pilkington Pyrostop® for superior level of insulation (EI), Pilkington Pyrodur® for enhanced integrity (EW), Pilkington Pyroclear® for basic integrity (E), and Pilkington Pyroshield™ 2 a wired glass for integrity-only (E) com-bine fire resistance and design flexibility, for peace of mind, elegant and functional buildings.
All our fire-resistant glass types are CE Marked building products and are labelled according to the actual CE Marking guidelines.
Why fire-resistant glass? New and existing buildings according to regulations in force should provide suitable level of fire safety. The ordinary clear float glass widely used in buildings does not provide any fire resistance proper-ties in case of fire. It tends to break at a temperature difference equal to about ΔT = 40°C. Ordinary laminated safety glass also has little resistance to fire – the glass breaks almost as quickly as clear float. Furthermore, at a temperature of about 250°C, when the PVB foil melts and fails to retain the glass fragments, the glass collapses and flames, smoke and hot gases can pass through the glazing. Whilst standard toughened glass is more resistant to high temperatures and temperature differences, it generally cannot survive temperature dif-ferences higher than about 300-350°C. All these glasses have, there-fore, no reliable performance in fire.
That is why it was necessary to introduce glass products that could withstand typical high temperatures in fire of approx. 1000°C for a defined time (see also figure 3.2), and additionally in the event of fire, would be able to give people the maximum amount of time for safe escape. Pilkington Pyrostop® and Pilkington Pyrodur® meet these criteria at different levels.

How does it work? Pilkington Pyrostop® and Pilkington Pyrodur® are clear, multi- layered fire-resistant glasses made of clear or extra clear float glass (Pilkington Optifloat™, Pilkington Optiwhite™), laminated with spe-cial transparent intumescent interlayers. When exposed to fire, the pane facing the flames fractures but remains in place, and the interlayer immediately foams up to form a thick, resilient and tough insulating shield that absorbs the energy of the blaze. This takes place at only modest temperatures of around 120°C, so that protection is provided right from the early stages of a fire. The resilient sandwich structure of Pilkington Pyrostop® and Pilkington Pyrodur® ensures that they stay in place and continue to act as an insulating fire-resistant wall for the required time periods, as defined in the relevant test standard.
Pilkington Pyrostop® and Pilkington Pyrodur® have successfully been tested in many fire doors, partitions and façade systems, covering vertical, horizontal and inclined glazing situations all over the world.
Pilkington Pyroclear® is a clear, monolithic fire-resistant and safety glass for up to 60 minutes basic integrity performance. It is also available in insulating glass unit form. Pilkington Pyroshield™ 2 is a range of monolithic fire-resistant wired glasses for 30 minutes basic integrity performance.
Definitions: l Integrity (class E) The ability of the system to keep back flames, smoke and fumes.
No flaming on the non-fire side is permitted within the approved time classification.
l Radiation (class EW) In addition to the integrity, the ability of fire-resistant systems to
limit the radiant heat on the non-fire side to15 kW/m² at a distance of 1 m to the surface, in order to prevent for example the ignition of goods on the protected side.
l Insulation (class EI) In addition to the integrity, the ability of glazed screens or doors to
limit the average temperature rise on the non-fire side to 140°C and the maximum temperature rise to 180°C above ambient temperature.

Pilkington Pyrostop®
Fire-resistant glass for integrity and insulation
Description Pilkington Pyrostop® is a clear, multi-laminated fully insulating fire-resistant safety glass that offers the highest level of fire pro-tection, effectively blocking the transmission of conductive and radiant heat, while maximising the transmission of natural light and transparency.
Applications Pilkington Pyrostop® is designed for interior and exterior use where thermal insulation is required in the case of fire up to class EI 180. It is suitable for use with steel, aluminium and timber frames in monolithic form or insulating glass units. Pilkington Pyrostop® is ideal for use in transparent fire walls, windows (special application), doors, screens, partitions and façades as well as for horizontal appli-cations (roof and inclined glazing).
Features and benefits l Extensively tested in a variety of framing materials and systems. l Provides proven integrity and insulation for up to 180 minutes
when used in a suitable, tested glazing system, restricting the spread of flames, smoke and hot gases and effectively blocking the transmission of conductive and radiant heat from the fire.
l Special clear intumescent interlayers, reacting to form a rigid, opaque, visual barrier to flames, helping to reduce panic and fear during evacuation of the building.
l Maximum light transmission for thicker versions that use Pilkington Optiwhite™ low-iron glass.
l Totally clear, unobstructed vision. l Impact safety. l Provides effective noise control. l Can be combined with other functional glasses for greater flexi-
bility in applications. l Available in different thicknesses and compositions for internal
or external use. l Available in monolithic or insulating glass unit form.

Noise Control
We all suffer from the intrusion of noise at some time or another. With an increasing population density, factory production and transport, the noise seems to get worse with fewer opportunities to escape. Along with the increase in noise is a growing awareness of the effect on health due to the stress caused by everyday sounds intruding into once quiet environments. The trend for the future suggests that traffic and noise in general is going to get worse as living space declines. There is an increasing interest in ways to pro-tect people from noise to avoid the considerable stress that it causes and in some cases serious illness.
A considerable amount of work has been done to control noise intru-sion into a building and between adjoining areas, and whilst this is valuable we want to concentrate on the contribution that the careful selection of glass has to offer in managing the problem.

in water.

Noise Control
There are five factors that can be combined, which can positively influence the sound insulation of an insulating glass unit.1. Glass mass.2. Asymmetric structure.3. Large gap between panes.4. Use of alternative gases.5. Use of Pilkington Optiphon™ special laminated safety glasses or
Cast In Place (CIP) products.
For the higher sound insulation requirements, modern sound insulating laminated safety glass products such as Pilkington Optiphon™, are becoming increasingly prevalent in comparison to the cast-in-place resin products because RW values of even more than 50 dB can be achieved and they can be supplied in large sizes. The compatibility of PVB with other materials is well understood and safety benefits such as impact protection / safer overhead glazing can also be achieved.

Technical definitions
Sound Reduction IndexRw is the weighted sound reduction, in decibels, which incorpora-tes a correction for the ear’s response. C and Ctr are the spectrum adjustments, which are the values added to Rw to take account of the characteristics of particular sound spectra. Typical noise sources for each spectrum adaptation terms are given below.
Relevant spectrum adaptation term CType of noise source:l Living activities (talking, music, radio, TV)l Children playingl Railway traffic at medium and high speedl Jet aircraft, short distance awayl Motorway traffic > 50 mphl Factories emitting mainly medium and high frequency noise.

Pilkington Optiphon™
Laminated glass with high sound insulation
DescriptionPilkington Optiphon™ is a high quality acoustic laminated glass with a special PVB (PolyVinylButyral) interlayer that offers excellent noise reduction without compromising on light trans-mittance or impact performance.The desired acoustic performance can be achieved through combi-ning various thicknesses of glass with a PVB interlayer. With a large variety of product combinations, Pilkington Optiphon™ offers the opportunity to achieve specific noise reduction requirements.Pilkington Optiphon™ can be combined with other Pilkington products for a multi-functional noise-reduction monolithic glass or a multi-functional noise-reduction insulating glass unit provi-ding additional benefits, such as thermal insulation, solar control or self-cleaning.
ApplicationsPilkington Optiphon™ is the ideal choice of glass in situations where there is excess noise from road, rail or air traffic, or other sources such as factories or nightclubs.
Benefitsl Provide a range of noise control levels.l A thin and lightweight solution to noise problems.l Achieve safety class 1(B)1 (EN 12600) and is available to meet
security glass classifications in accordance with EN 356.l In case of breakage remains intact, minimising the risk of injury.l Widely tested.l Easy to process, and can be incorporated into insulating glass units.l Can be single, double or triple glazed. l Can be combined with other Pilkington products for a multi-
functional noise-reduction monolithic glass or a multi-functional noise-reduction insulating glass unit providing additional bene-fits, such as thermal insulation, solar control or self-cleaning.
l Available thicknesses: 6,8 mm; 8,8 mm; 9,1 mm; 10,8 mm; 12,8 mm; 13,1 mm.

www.pilkington.com144
Safety / Security
Demanding safety legislation has highlighted the critical areas where modern safety glazing must comply with the relevant safety requirements. Innovations in the development of Safety / Security glass have opened up new avenues of design, which allows people to be protected from personal injury and, in the most extreme cases, protect buildings from various forms of attack.
With this in mind, we have developed a wide range of sophisticated products, in order to meet these ever increasing demands, without compromising on design criteria of natural light and visibility. We are always at the forefront in further developing the products and the indu-stry standards, so that personal accident and serious injuries resulting from glass impact are further prevented or minimized.
What does “Safety” and “Security” mean?
Although Safety and Security are closely linked topics, it is impor-tant to understand the distinction between the two terms, to ensure the right glass is specified.
The term “Safety” is applied to glazing used to reduce the risk of accident by impact, fracture, shattering, or in a fire. The term
“Security” is applied to glazing, which in addition to “Safety”, is able to withstand a variety of deliberate attacks such as physical, armed or blast.
Using only the right type of glass is not enough to secure the necessary resistance to the severe loads. The glass, once impac-ted, behaves differently in different framing systems, it is therefore imperative to combine high performance glazing with high perfor-mance framing systems.

The standards
EN 12600 Glass in building – Pendulum test –Impact test method and classification for flat glass The pendulum impact test is the standard for classifying flat glass products by performance under impact and by mode of breakage. Similar in principle to previously used swing bag tests, EN 12600 utilises a dual rubber tyre impactor to strike the glass at three drop heights.
The classifications are summarised below.
The classification has three components: l The first is the class (i.e. 1, 2 or 3) at which the glass has either not
broken or broken safely.l The second is the mode of breakage defined as: Type A: numerous cracks appear forming separate fragments
with sharp edges, some of which are large – typical of annealed glass.
Type B: numerous cracks appear, but the fragments hold together and do not separate – typical of laminated safety glass.
Type C: disintegration occurs, leading to a large number of small particles that are relatively harmless – typical of toughened glass.
l The third is the highest drop height (i.e. 1, 2 or 3) at which the product did not break (e.g. for toughened glass) or where it broke, but no shear or opening bigger than 76 mm in diameter appeared.

EN 1063 Glass in building – Security glazing –Testing and classification of resistance against bullet attackThis specifies performance requirements and test methods for the classification of bullet resistant glass, based on attack by handguns, rifles and shotguns.
The test consists of 3 shots fired on the vertices of a 100 mm equi-lateral triangle glass sample with a weapon corresponding to the required class.
If the glass sample has not been pierced by the shots then the required class is achieved. Behind the glass sample is an alumi-nium witness sheet. If after the shots have been fired there are some perforations on it, then the resistance class must have the suffix S (splinters), otherwise it is classified NS (no splinters).
These classes of resistance are summarised below.

Pilkington Toughened Safety Glass
DescriptionPilkington Toughened Safety Glass is manufactured by subjecting the final glass size to a heating and cooling treatment which sets up high compressive stresses at the surface and balancing tensile stresses in the centre of the glass, which increases glass strength. The result is a glass that is 5 times stronger than ordinary glass of the same thickness.
The high compressive surface stresses give the glass its increased resistance to mechanical and thermal stresses. It can, however, break under extreme loads or by severe impact. When broken, toughened glass shatters into small, blunt-edged fragments, reducing the risk of personal injury.
Most Pilkington products are available in toughened form.
ApplicationsPilkington Toughened Safety Glass provides an economical and proven solution where national standards or Codes of Practice specifically require the use of safety glazing material.Examples include passageways, areas of high pedestrian traffic, in doors and adjacent panels, shower and bath enclosures, balconies, barriers, staircases and other structural glazing applications.
Heat soaking is an additional process that can be carried out on Pilkington Toughened Safety Glass to reduce the remote risk of breakage due to inclusions within the glass.

Pilkington Optilam™ (safety glass)
DescriptionPilkington Optilam™ is a laminated safety glass which consists of two or more panes of glass bonded together by heat and pressure with one or more sheets of flexible PVB (PolyVinylButyral) inter-layer, sandwiched permanently between the glasses. The interlayers ensure the integrity of the glass, by holding the broken pieces in place should damage occur. In fact, glass fragments adhere strongly to the interlayer, while the resistant cushioning effect dissipates the energy. The performance of Pilkington Optilam™ can be influenced simply by changing the number and thickness of each layer of glass and PVB interlayer. By doing this, we can offer a wide range of products suitable for many applications.

www.pilkington.com156
Self-cleaning
Pilkington made a significant step in the glass industry with the development of Pilkington Activ™, the first dual-action self-cleaning glass. The unique dual-action of the Pilkington Activ™ coating uses the forces of nature to help keep the glass free from dirt, giving not only the practical benefit of less cleaning, but also clearer, better-looking windows. The Pilkington Activ™ coating, located on surface #1 of the glass, works in two stages. Firstly, it reacts with natural daylight to break down and loosen organic dirt. Secondly, when it rains, instead of forming droplets, the water spreads evenly over the surface of the glass, forming a thin film and helping to wash any dirt away, preventing the formation of drying spots and streaks, and helping the glass to dry very quickly. In installations where condensation is a problem, it reduces its visibility and helps it to evaporate more quickly.The Pilkington Activ™ coating works also on cloudy days and during the night. During dry spells the glass can be cleaned by simply hosing it down with clean water.

Pilkington Activ Suncool™
Dual coated self-cleaning, solar control andlow-emissivity glass
DescriptionPilkington Activ Suncool™ is a range of self-cleaning, superior solar control and thermal insulation performance dual coated glasses: – surface #1 pyrolytic on-line self-cleaning coating with photo-catalytic and hydrophilic properties; – surface #2 superior off-line solar control and low-emissivity coating, with high light transmittance, low, medium or high light reflectance and outstanding U value (down to 1,0 W/m²K) in a double insulating glass unit. The external self-cleaning coating bre-aks down the organic dirt, and rain water washes any loosened dirt away. The internal solar control and low-emissivity coating reflects short wavelength solar radiation out of the building, as well as long wavelength heat radiation (generated by heating systems, lighting and building’s occupants) back into the building.Pilkington Activ Suncool™ effectively reduces solar heat gain, at the same time providing high level of light transmittance and aes-thetic appearance.Pilkington Activ Suncool™ is available in a wide range of clear or neutral appearances and in two distinctive colours: blue and silver.

Global Glass Handbook 2011 – Architectural Products
Self-cleaning
Glass used today in commercial buildings and offices, has to pro-vide multiple functions. A technical profile of large glazed areas must meet requirements related to solar control, thermal insulation and noise control, as well as strict safety regulations. These require-ments can now be combined with self-cleaning properties.
Dual coating technology is used to combine self-cleaning and solar control properties in one product, ensuring a highly cost effective glass combination.
In the commercial sector the glass often needs to provide additional protection features. To meet these requirements, Pilkington offers two product lines of laminated safety glass. When using lamina-ted Pilkington Activ™ glass for façade elements and on glazed roof and sloping areas which are difficult to access, both safety and self-cleaning can be assured.The same applies to the combination of self-cleaning proper-ties with noise control of the façade. Functional glass, such as Pilkington Activ Optiphon™ allows a significant decrease in costs of window cleaning, and at the same time, it has an increa-sed sound reduction index (Rw).

Pilkington Texture Glass
Rolled patterned glass
DescriptionA rolled patterned glass, one surface of which has a specific pattern or design impressed into the surface, Pilkington Texture Glass pro-vides obscuration and decoration. The patterned glass allows the passage of light but depending on the depth and configuration of the pattern, varying degrees of obscuration are obtained. All patterns are classified according to their obscuration in relation to each other, the gradation being from 1 (least obscuring) to 5 (most obscuring).
ApplicationsThe designs give scope for combining functional suitability with decorative effect, whilst emphasising the natural light-enhancing properties of glass. The glasses can be supplied in toughened or laminated form for safety and incorporated into insulating glass units for thermal insulation or noise control.
Pilkington Texture Glass is translucent, with diffused light transmit-ted but privacy is maintained. It offers a wide selection of alternati-ves, meeting both functional and aesthetic requirements and may be used for privacy in commercial, industrial and residential buildings. It may also be used for decorative purposes in applications such as doors, partitions and balustrades.

Pilkington Mirropane™
High reflective pyrolytic on-line coated glass for one-way vision
DescriptionPilkington Mirropane™ is an on-line coated glass developed for use as a one-way mirror where clear vision is required and specific lighting conditions can be achieved. It offers an effective means of providing undetected surveillance and high quality one-way vision to achieve complete privacy.
In order to maintain privacy in the observing area, the ratio of illu-mination levels between public and private side, or observed and observing side, must be at least 8:1. It is also advisable, if absolute privacy is essential, to have dark furnishings, to wear dark clothing in the area from which observation is taken place, and to ensure the lights on the observed side are not directed at the glass.
ApplicationsPilkington Mirropane™ is the ideal choice for supermarkets, compu-ter rooms, banks or cash offices, where areas need to be kept under observation or hidden from public scrutiny. It is also appropriate for patient monitoring in hospitals or residential care establishments. Pilkington Mirropane™ is available in 6 mm annealed form.
Pilkington Mirropane™ is normally only used for internal applica-tions. The glass must be installed with the coating on the subject’s (observed person) side. In such position the glass creates a visual barrier between subjects and their observers, performing like an ordinary mirror on one side and a tinted window on the other.
If you would like to use Pilkington Mirropane™ in external applica-tions, please contact your local Pilkington representative.

Pilkington OptiView™
Pyrolytic on-line coated anti-reflective glass
DescriptionPilkington OptiView™ and Pilkington OptiView™ Protect are on-line coated anti-reflective glasses. Pilkington OptiView™ is a monolithic glass with the anti-reflective coating on one surface. It reduces visible light reflectance and allows more visible light to pass through, when compared to clear float glass (8% light reflect-ance as standard). Pilkington OptiView™ Protect is a laminated glass with anti-reflective coatings on surfaces #1 and #4 (both outer surfaces of the laminated glass), which reduces interior and exterior visible light reflectance to around 2%. As a consequence, views from both inside and out are clear, un-obscured and virtu-ally reflection-free. Pilkington OptiView™ Protect offers all the traditional benefits of laminated glass, such as improved safety, enhanced security, durability and acoustic properties. Furthermore, it provides protection from UV radiation (UVA and UVB) by blocking over 99% of UV transmittance, helping to reduce fading of the contents and interiors of a building.

Pilkington Optiwhite™
Extra-clear low-iron float glass
Today the use of glass in architecture and design is becoming more and more prevalent, and Pilkington Optiwhite™ is at the very fore-front of making it possible. The reason for this is the sheer variety of benefits which Pilkington Optiwhite™ can offer, making it an excellent choice for a wide range of applications.
DescriptionPilkington Optiwhite™ is an extra-clear, low-iron float glass; it is practically colourless, and the green cast inherent to other glasses is not present. It is therefore ideal for use where glass edges are visible or where a neutral colour is desired. As its light transmis-sion is 1% and 6% higher than clear float glass in 3 mm and 15 mm thickness respectively, it is perfect for applications where trans-parency and purity of colour are desired. Available in thicknesses of between 2 mm and 19 mm (the widest range on the market), Pilkington Optiwhite™ provides increased design flexibility and, when combined with other Pilkington products, it can offer addi-tional benefits such as thermal insulation or self-cleaning.

Pilkington Optiwhite™
Applications
INTERNAL GLAzINGLaminated glass used in internal glazing provides safety and secu-rity by marrying together multiple layers of standard float glass and PVB interlayers. However, this process also exaggerates any tint of colour inherent to the product. This is much less noticeable when using Pilkington Optiwhite™ as the substrate for laminated glass. The resulting product is free from inherent darkening conven-tionally associated with laminated glass incorporating the thicker clear float glass used for enhanced safety and security, making Pilkington Optiwhite™ the ideal alternative solution for balustrades, balconies, doors, partitions and stairs.
ExTERNAL GLAzINGOne of the most attractive features of Pilkington Optiwhite™ is its ability to achieve greater brilliance and transparency, allowing a clear and true representation of colours when viewed through the glass. These same qualities also allow for great interior daylight, which no doubt explains why Pilkington Optiwhite™ is the prod-uct of choice for architects for buildings where transparency and brightness are of paramount importance. Thanks to these and the many other benefits that Pilkington Optiwhite™ brings to exterior applications, it is the perfect choice for façades. When used in shop fronts, it enhances true colours and allows maximum light transmis-sion, even in thicker laminated combinations. In domestic windows, Pilkington Optiwhite™ maximises passive solar gain to reduce the need for heating during cold sunny days.
FURNITURE AND OTHER APPLICATIONSPilkington Optiwhite™ is also ideal for applications where glass is used as a design feature, such as glass tables. The same is true where glass edges are purposely exposed – for example, shelving and shower screens – where its clarity enhances the entire appear-ance of the furniture. In applications such as display cabinets, the high light transmission of Pilkington Optiwhite™ allows for a true representation of the potentially high-value products inside. Its inherent ability to make colours appear brighter also means that Pilkington Optiwhite™ provides an exceptional base glass for tiles, splash-backs and furniture doors, and gives more accurate colour definition when used as a mirror base.
