Home Insulation Insulation Board

Insulation Boards & Sheets

Insulation boards are used for thermal resistance in walls, roofs, and floors. They can be used to create a continuous insulating layer that helps maintain indoor temperatures. This quality of thermal support can also be raised with solutions that include foil facing, mineral glass coating, and more to improve U-value further. In addition, when installed in homes or commercial premises, they can reduce noise pollution. 

Also known as roof insulation boards or insulation panels, materials for an insulation board vary from PIR (polyisocyanurate) to wood fibre, aluminium, and many more. Foam insulation boards are common among these, including PIR, which is known as rigid foam board insulation because of its high compressive strength and moisture resistance. Regardless, plenty of different insulation board materials are easy to handle and can be cut to fit specific dimensions. 

Browse our range of insulation boards at Insulation Superstore from leading brands like Kingspan, Cellecta, Celotex, and IKO. You can also contact our excellent customer service team for further advice, if needed, via our helpline or the chat box in the bottom right.

Don't forget these when installing your new insulation boards and sheets:
