Description
A rigid extruded polystyrene (XPS) board highly resistant to compression and that can withstand both occasional and long term static loads.
Features and benefits:
- Square edged boards. Larger boards are lap jointed.
- Very high compressive strength.
- Protects the damp proof membrane from damage.
- Highly resistant to water absorption.
- Robust and can tolerate traffic from following trades.
- Represents no known threat to the environment and has zero Ozone Depletion Potential (ODP) and a Global Warming Potential (GWP) of less than five.
- 100% recyclable.
- BBA approved.
- BRE Environmental Product Declaration (EPD).
- BES 6001 Responsible Sourcing for Construction Products.
Technical characteristics:
- Vapour resistivity: The XPS content of Polyfoam Floorboard Extra has a water vapour resistivity of 625 MNs/g·m when tested in accordance with EN 12086.
- Moisture absorption: 0.7% by volume when tested in accordance with EN 12087.
- Durability: Continuous service temperature limits up to +70ºC.
