Description
A lightweight, lap jointed board with high compressive strength.
Features and benefits:
- Excellent thermal performance.
- 15 mm lap joint.
- High compressive strength.
- Highly resistant to water absorption.
- Able to resist repeated freeze/ thaw cycles.
- Lightweight and easy to install.
- Tough and durable, not easily damaged.
- Dimensionally stable.
- Thermal performance of an inverted roof is improved when used in conjunction with Polyfoam Slimline Zero Membrane (specified separately).
- 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.
Technical characteristics:
- Vapour resistivity: The water vapour resistivity of Polyfoam Roofboard Super is 750MNs/g.m when tested in accordance with BS EN 12086.
- Moisture absorption: 0.7% by volume when tested in accordance with EN 12087 and can be laid in standing water with negligible impact on the performance of the product.
- Durability: Continuous service temperature limits up to +70ºC.
