If you are interested in purchasing some 40mm insulation board, one of our most popular variants is the 40mm Quinn Therm PIR Insulation Board 2400x1200mm. This is a high performance, fibre freeboard, with a rigid thermoset insulation core and faced on both sides with a low emissivity composite foil facing. It is perfectly suitable for new build and refurbishments projects in both domestic and commercial build.


By using this foil faced insulation, it can be an excellent way of storing and increasing the amount of heat in a house that may need an extra boost in warmth. The foil reflects the heat back into the attic space and keeps it stored in this area, cutting down on utility bills and even making the property cooler in the warmer months. You can also rest assured that the 40mm insulation boards will not bend, break or sag but will, on the contrary, contribute to the overall integrity of the wall structure.
