Technical Specification
The extruded polystyrene content of Polyfoam Upstand Board has a thermal conductivity of 0.033W/mK, the facing board has a thermal conductivity of 0.47W/mK.
The XPS content of Polyfoam Upstand Board has a water vapour resistivity of 625MNs/g.m when tested in accordance with EN 12086.
Polyfoam Upstand Board has a moisture absorption of 0.7% by volume when tested in accordance with EN 12087.
In accordance with EN1301-1:2007, the weather resistant facing board on Polyfoam Upstand has a reaction to fire classification of A1. The XPS content is Euroclass F.
Polyfoam XPS represents no known threat to the environment and has zero Ozone Depletion Potential (ODP) and uses a blowing agent with a low Global Warming Potential (GWP). The XPS content of Polyfoam Upstand Board is non bio-degradable and 100% recyclable.
The continuous service temperature limit of Polyfoam Upstand Board is up to +70º C.
Polyfoam Upstand Board is lightweight and easy to handle and install, the boards should be cut to size using a tungsten carbide tipped (TCT) saw, when cutting through the facing material it is advisable to wear a facemask.
Polyfoam Upstand Board is supplied on pallets, labelled with identifying product and manufacturing data and wrapped in a polythene shroud for temporary protection during transit and on site. Ensure the boards are not stored close to open flames or other ignition sources, also avoid volatile compounds and chemicals such as solvents.
Polyfoam XPS 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 Upstand Board should have edges and corners protected to prevent chipping.
