LAYING PATTERN

The boards should be laid over a

non–bituminous vapour control layer.

Boards should be laid with edges butted

and in a break bonded pattern laid at

right angles to the edges of the roof or

diagonally across the roof.

The board is suited to a variety of laying

patterns. However, it is recommended

that whatever pattern is employed joints

are always break-bonded. On metal decks the long edges should be laid at right

angles to the corrugations. All board joints should be fully supported by the deck.

HEALTH & SAFETY

These rigid PIR foam products are chemically inert and safe to use. A leaflet

about satisfying the requirements of the "Control of Substances Hazardous to

Health Regulations, 1988' (COSHH) is available.

HANDLING

■ Do not drop boards

■ To cut use a sharp knife or fine tooth saw

■ Wear eye protection

■ Damaged boards should not be used

Cutting with power tools generates dust so should be kept to a minimum.

Ideally all operations which produce dust should be carried out in well ventilated

conditions; where possible a dust mask selected in accordance with BS EN 149

should be worn.

Ensure accurate trimming to achieve close butt joints and continuity of insulation,

particularly around projections through the roof.

Whenever work is interrupted, a night joint must be made to prevent water

penetration.

STORAGE

Store boards in a flat, dry area off the ground away from possible mechanical

damage and sources of ignition. Boards should be completely covered with

weatherproof sheeting.

The boards must be kept dry at all times and not exposed to rain. Boards wetted

accidentally must be replaced or allowed to dry fully before application of the

waterproof layer.

The boards must be protected from prolonged exposure to sunlight and should

be stored either under cover or covered with opaque polyethylene sheets.

DIMENSIONS

Available in standard sizes and various thicknesses as shown below:

Width: 1200mm

Length: 2400mm

Thickness: As per Table 1 30 to 200mm.

COMPRESSIVE STRENGTH

Typical compressive strength for the foam exceeds 150KPa when

tested to BS EN 826: 1996 Thermal Insulating Products for Building

Applications-Determination of compressive behaviour.

DENSITY

PIR foam has a density of 32 Kg/m3

DURABILITY

The product is stable, rot proof and durable and will remain effective

as an insulation system at least as long as that of the waterproof

covering. Durability depends on the method of application, the

supporting structure and conditions of use.

The insulation core and facings resists attack by mould and microbial

growth, and do not provide any food value to vermin.

MOISTURE TOLERANCE

PIR core of EcoTherm Insulation boards has a low moisture absorption

capacity, making it tolerant for use in damp environments.

RESISTANCE TO SOLVENTS - FOAM

EcoTherm roofboard resists attack from alkalis, dilute acids, mineral oil

and petrol. The foam is not resistant to ketonic solvents. Boards which

have been in contact with harsh solvents, petrol, mineral oil or acids

should not be used. Damaged boards should not be used.

THERMAL CONDUCTIVITY

The low emissivity surface of the reflective foil can cut radiation heat

transfer across an adjoining air-space.

The thermal conductivity (λ value) of the foam is 0.022 W/mK and the

thermal resistances of the range within given constructions are shown

in Table 1.

TYPICAL WEIGHT

120mm board is 11.8kg

WATER VAPOUR RESISTANCE

Foil facings have a high water vapour resistance and will, therefore,

provide significant resistance to water vapour transmission. This will

minimise both surface and interstitial condensation.

The necessity for the inclusion of a water vapour control layer in the

roof construction should be assessed in accordance with BS 6229:2003

Code of Practice for flat roofs with continuously supported coverings.

Where the specified vapour control layer is other than a bituminised

felt, eg polyethylene, any fixings which penetrate the vapour control

layer should be of the self-sealing type, which are automatically fused

to the vapour control layer during application.

DESIGN CONSIDERATIONSConsideration should also be given to BS 5250: 2002 Code of Practice for control of condensation in buildings and BS 6229: 2003 Code of Practice for flat roofs with continuously supported coverings. Mechanical fixings should be specified as recommended in the BRUFMA information document ID/1/2009

ENVIRONMENTALPIR foam is CFC/HCFC free and Zero Ozone Depletion Potential (ODP) with a Global Warming Potential (GWP) of 3, better than the target value of 5. It has BRE Green Guide rating of A.

FIREThe fire rating of any roof containing the boards will depend heavily on the type of deck and the nature of the roof waterproof covering. The designation of the roof covering must meet the requirements of the national Building Regulations.

Further details on the fire performance may be obtained from EcoTherm Technical Services.

Achieves BS476-7: 1997 Class 1 rating for surface spread of flame.

ROOF LOADINGDepending on the chosen waterproofing system, EcoTherm insulation is suitable for use on roof decks which are subject to limited maintenance foot traffic. Walkways should be provided on roofs requiring regular pedestrian access. Whenever site work is to take place after the insulation has been laid, and the roof made water tight, the roof should be covered with protective board.

MECHANICAL FIXINGThe fixings used to secure the waterproofing membrane in most circumstances are also used to secure the EcoTherm roofboards. However, irrespective of the wind uplift considerations or distribution requirements for securing the membrane, the fixing of the boards should be considered separately.

The number of mechanical fixings required to fix EcoTherm roofboard will vary with the geographical location of the building, the topography and the height of the roof concerned. BS 6399-2 1997 should be consulted. It is essential that the EcoTherm roofboard is restrained over its full surface

area. A minimum of 6 mechanical fixings should be placed within the individual board area and be sited adjacent to the corners of the board. Any additional fixings needed should be evenly distributed over the full area of the board. Each fixing should incorporate a minimum 50mm diameter countersunk washer which must not restrain more than one board. Where alternative bar-fixing systems are specified the restraint offered by the specified system must at least equal the restraint that would be attained by the use of conventional washer and screw systems. The suitability of the substrate to accept and retain mechanical fixings must be checked prior to the work commencing. EcoTherm recommends the use of thermally broken tube fasteners.

STANDARDS AND APPROVALS PIR foam is produced according to BS EN 13165: 2008 Thermal insulating products for buildings-Factory made rigid polyurethane foam products-specification.

Eco-Fix is compliant with BS 4841-4: 2006
