For the thermal insulation and protection of upstands in flat roofing

Description

Polyfoam High Impact and Upstand Board is a laminate of Polyfoam high performance, 100% ozone friendly, extruded polystyrene, rigid insulation board and a tough, weather resistant fibre reinforced cement facing board.

Polyfoam High Impact and Upstand Board is square edged.

Application

Polyfoam High Impact and Upstand Board is used for the thermal insulation and protection of upstands in flat roofing. It can also be used as a lining, where strength, fire performance and potential for easy cleaning are important, such as in agricultural buildings.

Where a greater thickness of insulation is required, see the Polyfoam Soffit Liner Board datasheet.

Standards

Polyfoam High Impact and Upstand Board is manufactured in accordance with BSI Quality Assurance Standard BS EN ISO 9001: 2000.

Environmental

Polyfoam High Impact and Upstand Board is free from CFCs, HCFCs and any other material with ozone depletion potential in its manufacture and content and represents no known threat to the environment.

Polyfoam High Impact and Upstand Board is non bio-degradable.

Polyfoam High Impact and Upstand Board is 100% recyclable.

Thermal Performance

The extruded polystyrene in Polyfoam High Impact and Upstand Board has a thermal conductivity of 0.030 W/mK.

Fire Performance

The cement facing board is classified as Class 1 Surface Spread of Flame to BS476: Part 7: 1987.

Compression resistance

The strength of Polyfoam offers a wider range of potential solutions to design problems.

The facing material is highly resistant to impact damage, offering an excellent robust finish.

Moisture resistance

Polyfoam is highly resistant to moisture absorption and can be installed in a damp area or during moist conditions with negligible impact on the performance of the product. The facing material is moisture resistant.

Fire performance

Polyfoam insulation contains a flame retardant which inhibits localised ignition. Polyfoam High Impact and Upstand Board is faced with a 6mm fibre reinforced cement board which offers excellent fire performance as a facing material and is classified as Class 1 Surface Spread of Flame to BS 476: Part 7: 1987.

Handling and storage

The boards are easy to handle and nonirritant, when cutting through the facing material it is advisable to wear a facemask to guard against dust. No special protective clothing is required.

Polyfoam High Impact and Upstand Board is supplied on pallets, labelled with identifying product and manufacturing data. They should be wrapped in a polythene shroud for temporary protection during transit and on site.

Ensure the boards 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.

The facing board on Polyfoam High Impact and Upstand board should have edges and corners protected to prevent chipping.
