Uses of PIR Board

PIR insulation boards are incredibly versatile and can be seamlessly integrated into various parts of a building. They are perfect for installation in a pitched roof between the joists and in a warm flat roof to ensure durable and efficient insulation. These high-performance PIR boards can also be used as insulation in timber framing walls, where they are custom-cut and fitted between sheets to reduce thermal conductivity. They can also be strategically placed between ceiling joists and floor joists.

PIR insulation boards are a perfect fit for a wide range of insulation needs, delivering exceptional thermal support due to their compressive strength while enabling swift and hassle-free installation.

In addition to standard PIR Insulation, there are specialised products available for specific applications such as cavity wall insulation, flat roof insulation materials, and dry lining. Throughout a building, PIR insulation can be used to provide robust thermal support, fire resistance and improve energy efficiency.
