Knauf Climafoam® Extruded Polystyrene (XPS) is a closed cell foam board, which is highly resistant to water and provides excellent thermal performance. XPS foam boards are available in ‘ship lapped’ edge, for a neat and easy seal joint and do not deteriorate. Designed to increase the energy efficiency of your property, it also provides an extra barrier to protect from moisture ingress.

Climafoam® XPS insulation board is highly resistant to compression and withstands both occasional and long-term static loads. The high compressive strength and rigidity of the boards allow a range of ballast including gravel, soil and concrete slabs to be used as part of the construction. Load bearing construction elements should be designed to adequately support the combination of imposed and dead loads without creating excessive deflection.

XPS foam boards are used in a variety of applications including cavity walls, edge beams, green roofs, external walls, cool rooms, basement walls, and encasement within concrete slabs. The polystyrene foam material is efficient in reflecting heat from your room towards the surface. This means you will be lowering your energy consumption and carbon footprint, as well as protecting your property from damaging dampness.
