General

Would you like a property with an attractive exterior without

needing to compromise on energy savings, sound insulation

and fire safety? Lindab's sandwich panels are prefabricated

building components that guarantee high quality and low

costs. A wide range of profiles give you the opportunity to

create a façade or roof that suits your requirements and de-

sires.

The panels are manufactured from sheet metal with a highly

insulating core of mineral wool or EPS.

Technical facts - sandwich wall panels

Thermal insulation

Lindab's range of sandwich panels includes three core types;

mineral wool and EPS. A panel with a core of mineral wool

has a non combustible core, which is preferable if there are

stringent requirements regarding fire performance.

Below is a comparison showing the core thickness required

for a variety of panel types to achieve similar U-values.

EPS (expanded polystyrene), 150 mm = 0.24 W/m2 K

Mineral wool (high-density), 200 mm = 0.20 W/m2 K

Sandwich panels and fire

Additional classes

s1 The structural element may produce a very limited

amount of combustion gases.

s2 The structural element may produce a limited

amount of combustion gases.

s3 No requirement for limited production of smoke.

d0 Flaming droplets and particles may not be pro-

duced by the structural element.

d1 A limited amount of flaming droplets and particles

may be produced by the structural element.

d2 No requirement for limited amount of flaming drop-

lets and particles.

Lindab's sandwich panels are fire-tested and rated with ref-

erence to their reaction to fire as well as their fire resistance.

This is carried out through testing and classification accord-

ing to standards SS-EN 13501-1 and SS-EN 13501-2.

Reaction to fire

This method of testing shows how a building product reacts

when exposed to high heat in the form of a direct flame, radi-

ant heat or high temperatures. Reaction to fire tests can be

performed using a variety of test methods, including the SBI

method (Single Burning Item). Parameters such as smoke

formation, heat release and any flame spread are measured

to determine the product's fire characteristics. The following

classifications for combustibility are assigned based on the

limit values achieved by the tested product:

A1 or A2 for a non-combustible material B, C, D, E for a com-

bustible material, where B is lowest combustibility.

A1 is the highest class and is not combined with any addi-

tional class. The other classes are always combined with the

following additional classes which indicate the product's abil-

ity to produce smoke and flaming droplets and particles.

Swedish standards use the following classifications for internal building surfaces:

Class I B-s1, d0

Class II C-s2, d0

Class III D-s2, d0

Technical facts - sandwich wall panelsResistance to fire

This classification concerns a building product's ability to

withstand a fire flashover. The panels are tested and assigned

a specific class based on their function:

R Load-bearing capacity

RE Load-bearing capacity and integrity (containment)

REI Load-bearing capacity, integrity and insulation

E Integrity

EI Integrity and insulation

EW Integrity and limited radiation

Tests on fire cell partitions (wall panels) are performed in a

test furnace with a 3x3 m wall, with the temperature inside

the furnace normally reaching around 1000°C. The tempera-

ture on the unexposed side is measured at a number of points

and the requirement is that the average temperature may not

increase more than 140°C generally or 180°C at one specific

point. The integrity requirement means that no flames must

penetrate the joints. The time for which the panel satisfies the

criteria is measured and the panel is rated for integrity and in-

sulation followed by a time requirement in minutes, e.g. EI 60.

Fire engineering classes

Any fire cell partitions are normally of class EI 30, irrespective

of the fire load.

Technical facts - sandwich wall panelsCore types in Lindab sandwich panels

PUR B3 – Polyurethane B3

PUR B3 is normally classed as C or D-s3, d0. A PUR B3 foam

performs less well in a fire than type B2. It emits more smoke

and produces more heat during a fire. Unlike a B2 foam, a B3

foam is not self-extinguishing.

Fibreglass

Fibreglass is normally classed as A2-s1, d0. Fibreglass is, like

mineral wool, a mineral fibre, although its fire characteristics

are not as good as those of mineral wool. Fibreglass shrinks

at high temperatures. A fibreglass panel normally achieves a

maximum rating of EI 90.

Polystyrene (not flame/fire-resistant)

Polystyrene melts at temperatures as low as 180°C and pro-

duces a lot of flaming droplets during a fire. Once the core

melts the fire can also spread unchecked inside the non

flame-resistant panel. If the panel wall is not securely fixed, it

can collapse and accelerate the fire's progress. Despite this,

EPS can be classed as d0, because only droplets and par-

ticles that fall outside the so-called 'burn zone' of approx.

300x350 mm are counted during testing. A major study has

shown that some of the greatest industrial damage of mod-

ern times in the UK has involved flame-resistant polystyrene

panels installed internally in buildings.

Mineral wool

Mineral wool is normally classed as A2-s1, d0. Panels with

a hard core of high-density mineral wool fibre generally

achieves a very high fire performance and normally produces

less smoke and heat than a panel with a polymer core. How-

ever, even a mineral wool panel is not classed as wholly non-

combustible (class A1), as the fibre core contains binders and

the core is glued to the sheets, usually with a polyurethane

adhesive. For this reason, it is classed as A2. For structures

serving as fire cell partitions, where a high fire resistance is

required, requirements are satisfied only by panels with a

mineral wool core.

PIR - Polyisocyanurate

PIR is normally classed as B-s2, d0. A PIR core is a type of

polyurethane that has undergone significant material modifi-

cation. In the event of a fire the core chars on the exposed

side; this charred layer then protects the rest of the core from

the fire. This means that a panel with a PIR core is more re-

sistant to fire than a PUR B2 core. It also emits significantly

less heat and smoke.

PUR B2 – Polyurethane B2

PUR is normally classed as B-s3, d0. Panels with a rigid pol-

yurethane core also char in the event of a fire. However, the

charred layer is not as strong as that in a PIR core and it has

a relatively low resistance to fire.

A PUR B2 core produces no flaming droplets during a fire but

does emit quite a lot of smoke. However, it usually emits less

than a corresponding EPS panel. Full-scale tests have also

shown that there is no hidden flame spread inside the panel.

Studies using real fires and full-scale tests have shown that

PUR panels are only partly involved in the early stages of the

fire and are not affected until the fire has developed fully. The

core is self-extinguishing, which means that the core stops

burning when the heat source disappears. Studies have also

shown that a PUR panel that is fixed to the framework with

a continuous mechanical fastener does not fail until the sup-

porting framework fails.

Polystyrene (EPS) Quality F (flame/fire-resistant)

Flame/fire-resistant EPS quality F is classed as E. Polysty-

rene melts at 180°C. Panels with EPS quality F produce flam-

ing droplets at the seat of the fire and can produce a lot of

black smoke. EPS quality F is involved in a fire close to the

seat of the fire provided that there is another heat source and

for as long as the EPS panel's relatively low energy content

lasts. However, the core is self-extinguishing; i.e. when the

external heat source disappears, the fire in the panel ceases.

Real examples of dramatic and long-lasting fires show that

even buildings with high energy contents (building supplies

warehouses) with walls of EPS quality F to a large extent re-

main relatively unaffected outside the fire area.

Technical facts - sandwich wall panels

As the sun heats the outside of the panel, the external metal sheet extends and the panel moves outwards. During the winter, when it is colder outside than inside, the reverse is the case. For freely mounted panels, this movement has no direct load impact.

The temperature difference to take into account depends on the colour of the external metal sheet. A light colour reflects more solar radiation than a dark one, and therefore does not become as hot.

Holes for windows, doors etc.

Multiplication factors Ff for holes

Holes leads to an increased load on adjacent panels. The increased load can be taken into account by multiplying the wind load for the adjacent panels by a multiplication factor Ff

Ff depends on a number of standard cases below. Unless otherwise stated, it has been assumed that the size of the hole in the breadth direction of the panel bhole = 1.2 m. bpanel = covering width panel (m)

For smaller hole widths, the factor Ff which affects the adjacent panel can be reduced to Ff = 1+0.35 bhole/bpanel

In addition, the panel joints must be able to cope with transfer-ring the shear force between panels. This is fulfilled if the dimensioned wind load before load increase is a maximum of 1.5 x (bpanel/ bhole) kN/m2. If the loads cannot be managed, the wall must be reinforced.

Holes leads to increased deformations of the panels, which in addition vary along the sides of the drill holes. This should be taken into account during the structural design process so that, for example, sensitive windows are not damaged.

Without reinforcement, the maximum recommended frame breadth for vertical panels and frame height for horizontal panels is bpanel.

Fasteners are a very important part of any construction pro-

ject involving sandwich panels. At Lindab you will find a com-

plete range of fasteners for use with different materials in any

environment.

Our stainless steel screws for mounting panels on purlins and

steel profiles have been type-approved for use up to and in-

cluding corrosion class C4. Approval denotes an estimated

technical life of as much as 50 years.

The range also includes products such as external flashing

fastenings and panel washers.

For more information, see the chapter Fasteners.

General mineral wool panels

Lindab's mineral wool panels have a core of mineral wool in

different densities, but with a few exceptions are also avail-

able with an EPS core. The cores have different advantages

as regards fire class, security, insulation, weight etc. See the

tables for detailed information. Panels from 150 mm are avail-

able as security panels (not EPS).

Lindab's standard panel has a core of mineral wool and an

outside and inside of 0.6 and 0.5 mm sheet metal respec-

tively. The minimum standard length is 1.0 m. Lengths down

to 0.55 m can be delivered as options. The maximum panel

length is 6.0-12.2 m depending on the type and thickness.

Intrusion protection

Sandwich panels with intrusion protection

Good intrusion protection should impede and deter intruders.

Lindab's security classed panels deter intruders. The patent-

ed system with built-in reinforcement in the element makes it

very difficult to break through.

The element fulfils the requirements of protective class 2 in

accordance with Svensk stöldskyddsförening's regulation

SSF 200 – "Rules for mechanical intruder protection".

The solution is available with all patterns and combinations

for mineral wool elements with 150 mm thickness and above.

No compromise in terms of performance in general is re-

quired.

Foodsafe

Foodsafe is a food classed foil coating used for interior walls

and ceilings in food premises. Premises such as commercial

kitchens, preparation and manufacturing premises, ware-

house and storage premises require areas that are light, easy

to clean and with surfaces that do not emit hazardous sub-

stances.

The foil is a 150 μm thick polymer foil which is glued to the

sheet metal. It has the best properties in terms of ability to

resist mechanical wear and strong detergents

The coating is non-toxic and resistant to mould. The foil is

highly watertight, durable, easy to clean, chemically inert and

approved for use in the same premises as unpackaged food-

stuffs.

However the foil cannot be used outdoors as it yellows in the

sun's UV light.

At Lindab we simplify construction for our

customers. We do that by designing easy-

touse products and solutions, as well as

offering efficient availability and logistics.

We are also working on ways to reduce our

impact on our environment and climate. We

do that by developing methods to produce

our solutions using a minimum of energy and

natural resources, and by reducing negative

effects on the environment. We use steel in

our products. It’s one of few materials that

can be recycled an infinite number of times

without losing any of its properties. That

means less carbon emissions in nature and

less energy wasted.
