Celotex multi-purpose PIR insulation board is a high-performance product designed for use across a wide range of building applications. Suitable for pitched and flat roofs, solid floors, masonry walls, timber frames, and steel-framed systems, it offers both versatility and efficiency in one solution.
Manufactured from polyisocyanurate (PIR), the boards are lightweight, easy to handle, and simple to cut to size on-site. Despite its relatively slim profile, it provides excellent thermal performance with a thermal conductivity of just 0.022 W/mK, making it ideal for achieving demanding U-value targets.
In addition, the low-emissivity foil facings enhance performance further when used in sealed cavities, helping to improve overall energy efficiency. Whether you're upgrading an existing structure or working on new builds, Celotex multi-purpose PIR insulation boards offers a reliable and thermally efficient insulation solution.
