Kingspan insulation is typically made from high-performance rigid thermoset materials such as polyisocyanurate (PIR) or phenolic insulation foam, depending on the board type. These cores are often foil-faced or glass tissue-faced, enhancing both thermal insulation and durability. Kingspan’s advanced manufacturing delivers lightweight yet powerful insulation boards, ideal for modern construction needs.

To install Kingspan wall insulation: Choose the correct Kingspan insulation board type and size for your wall construction (internal, cavity or external). Ensure the surface is clean and dry. Fix boards directly to timber or metal studs using mechanical fixings or insulation adhesives. Tape joints with foil tape for a continuous thermal layer. Follow up with plasterboard or vapour control layers where required.

To cut Kingspan insulation boards: Mark your cut line using a straight edge. Use a fine-toothed saw, insulation saw, or utility knife for PIR insulation boards. Make clean cuts to ensure a snug fit and reduce thermal bridging. Always wear appropriate PPE, such as gloves and a dust mask. Cutting Kingspan insulation is quick and simple, making it ideal for custom fits in walls, roofs and floors.
