For the provision of thermal insulation and decking for storage in the loft spaces of pitched roofs

Description

Polyfoam Supadeck Total is a laminate of Polyfoam high performance, 100% ozone friendly, extruded polystyrene, rigid insulation board and a tough, moisture resistant chipboard.

The chipboard is P5 flooring grade and is tongue and grooved on all four edges.

Polyfoam Supadeck Uni is a high performance, 100% ozone friendly, extruded polystyrene, rigid insulation board, produced 480 x 1200mm to coordinate with standard chipboard loft boards.

Polyfoam Supadeck Duo is a double thickness of Polyfoam Supadeck Uni.

Application

Polyfoam Supadeck Total has been specifically designed and developed to provide thermal insulation and decking for storage in the loft spaces of pitched roofs. Polyfoam Supadeck Total laid over ceiling joists with 100mm Crown Loft Roll between, will achieve a U-value of 0.16 W/m²K.

Polyfoam Supadeck Uni and Duo provide a loft decking system, providing a stable surface for standard chipboard loft boards, enabling the creation of a loft storage deck, whilst insulating at the same time.

Polyfoam Supadeck Uni and Duo give the refurbishment user the option to use one later (Uni) or two layers (Duo) of insulation. Two layers will achieve a U-value of 0.16 W/m²K in the same manner as Polyfoam Supadeck Total.

Standards

Polyfoam Supadeck Total and Supadeck Uni/Duo are manufactured in accordance with BSI Quality Assurance Standard BS EN ISO 9001: 2000.

Environmental

Polyfoam Supadeck Total and Supadeck Uni/Duo are free from CFCs, HCFCs and any other material with ozone depletion potential in their manufacture and content and represent no known threat to the environment.

Polyfoam Supadeck Total and Supadeck Uni/Duo are 100% recyclable.

Compression resistance

Polyfoam Supadeck is highly resistant to compression and withstands the long term static loads imparted by loft storage.

Polyfoam Supadeck is capable of withstanding the applied point loading of the ceiling joists when loaded with storage items. Moreover, the chipboard in Polyfoam Supadeck Total is a high strength chipboard capable of withstanding the expected loads.

Warning: Polyfoam Supadeck Uni/Duo should not be walked on, they are not designed to support a persons weight, unless covered by a chipboard loft board.

Note that ceiling joists are not designed to take a floor load, care must be taken to ensure the load imparted on the ceiling is not excessive. If you are in any doubt as to the condition and strength of the ceiling joists seek professional advice.

Moisture resistance

Polyfoam Supadeck is in a cold roof space, but below the waterproofing, if any moisture is present, the insulation board is highly resistant to moisture absorption.

The chipboard facing material in Polyfoam Supadeck Total is a moisture resistant grade chipboard.

Fire Performance

Polyfoam Supadeck Total and Supadeck Uni/Duo contain a fire retardant additive. When installed in a roof construction they will not contribute to the development stages of a fire.

Compatibility with other materials

PVC insulated electrical cables should not be allowed to come into direct contact with the insulation in Polyfoam Supadeck Total and Supadeck Uni/Duo. Cables can simply be relocated so they lay on top of the finished chipboard deck.

Handling and storage

The boards are easy to handle and nonirritant, no special protective clothing is required when installing them. The boards are sized to be able to pass through standard sized loft hatches.

Polyfoam Supadeck Total and Supadeck Uni/Duo are supplied on pallets, labelled with identifying product and manufacturing data.

Ensure they are not stored close to open flame or other ignition source, also avoid volatile compounds and chemicals such as solvents.

Polyfoam products should not be left exposed to prolonged sunlight as this will result in surface degradation. Where outside storage for extended periods is required cover with opaque/light coloured sheeting.
