Polyfoam Floorboard Extra
The thermal conductivity of Polyfoam Floorboard Extra is 0.033 W/mK
Polyfoam Floorboard Extra is a rigid extruded polystyrene (XPS) board with a Global Warming Potential (GWP) of less than 5 and Zero Ozone Depletion Potential (ODP). It is a square edged board that has high compressive strength.
- High compressive strength – protects the damp proof membrane from damage
- Highly resistant to water absorption
- Robust and can tolerate traffic from following trades
Polyfoam Floorboard Extra is suitable for almost any floor construction including:
- Below a concrete slab
- Below a screed
- Below chipboard
The Polyfoam XPS range of products has been independently assessed under the BRE’s Green Guide to Specification, Polyfoam Floorboard Extra achieves a BRE Certified Green Guide rating of A+.
Polyfoam Floorboard Extra represents no known threat to the environment and have zero Ozone Depletion Potential and a Global Warming Potential of less than five.
Polyfoam Floorboard Extra is non bio-degradable and 100% recyclable.
The BRE have approved and issued Environmental Product Declarations (EPD’s) for the Polyfoam XPS range of products. This globally recognised standard enables construction companies and specifiers to gain independent verification of a product’s environmental credentials.
The continuous service temperature limits of Polyfoam Floorboard Extra is up to +70º C.
Polyfoam Floorboard Extra is resistant to moisture absorption and can be laid in standing water or up against wet concrete with negligible impact on the performance of the product as determined by testing to EN 12087.
Polyfoam Floorboard Extra – 625MNs/g.m when tested in accordance with EN 12086.
Polyfoam Floorboard Extra has a moisture absorption of 0.6% by volume when tested in accordance with EN 12087.
Handling and storage
Polyfoam Floorboard Extra is lightweight and easy to handle and install. Polyfoam Floorboard Extra are supplied in four sided packaging designed to be easily recognised and are labelled with identifying product and manufacturing data. Ensure the boards are not stored close to open flames or other ignition sources and avoid volatile organic compounds and chemicals such as solvents.
Polyfoam Floorboard Extra should not be left exposed to prolonged sunlight as this will result in surface degradation. When outside storage for extended periods is required cover the products with opaque/light coloured sheeting.
