Xtratherm Polyiso 75mm Insulation Board 2400x1200x75mm

For use in self-supporting floor, wall and roofing applications. This product is strong and durable, capable of supporting the weight of load bearing floors. These boards are thinner than most insulation, thanks to their extremely low level of thermal conductivity, allowing them to insulate your property with less thickness. Reflective foil cuts down on radiation heat transfer. Stable up to temperatures of 400ºC, over which a protective char slows flames spreading, this insulation board is safe to use directly behind flammable substrates e.g. plasterboard.
