What are PIR Boards?

PIR, also known as polyisocyanurate, is one of the most popular types of insulation because it comes in easy-to-install boards. Thanks to their manufacture, PIR insulation boards are easy to work with and easy to cut so PIR insulation is a favourite in the insulation industry. High thermal performance is created by blending materials together using heat, which causes gases to be released and get trapped in cells within the board. This type of insulation means heat can't pass through readily. Depending on the manufacturer and the intended use of the PIR insulation board, some are faced with foil or a mineral glass coating. Foil facings are moisture-resistant.
