Knauf Insulation has enhanced its Polyfoam ECO extruded polystyrene insulation range, to provide thicknesses of up to 240mm from just one layer. The new range allows lower U-values to be achieved and a considerable reduction in the global warming potential (GWP) of each product.
Polyfoam ECO, which encompasses Knauf Insulation’s Roofboard and Floorboard range, has excellent thermal performance, as well as being lightweight and easy to handle and install. It can achieve thermal conductivities as low as 0.033 W/mK across the whole range, meaning U-values as low as 0.13 W/m2K can be achieved with a single layer at 240mm. Manufactured in the UK, it achieves a GWP of less than five and an ozone depletion potential (ODP) of zero. The range is also 100 per cent recyclable.
The rigid board insulation has structural strength up to 500kPa. It is highly moisture resistant and easy to cut and shape. Thermal performance is unaffected by site conditions such as fluctuating outside temperatures and repeated freeze thaw cycles.
