The 128mm PIR and OSB SIP Structural Insulated Sandwich Panel is a high-performance construction board designed to provide outstanding thermal insulation, structural stability, and long-lasting durability for modern building applications. Manufactured with a rigid polyisocyanurate (PIR) foam core combined with two 9mm OSB facings, this panel delivers an efficient and reliable solution for energy-efficient construction projects.

With thermal conductivity values of 0.022 W/mK for the PIR foam core and 0.13 W/mK for the OSB facings, the panel provides excellent insulation performance while maintaining strong structural integrity. The foil-faced PIR core acts as an integrated vapour control layer, helping minimise moisture movement and improve the long-term protection of the building structure.

Featuring a square-edge profile, the panel enables accurate and straightforward installation using the butt joint technique. Suitable for roofs, walls, floors, and general construction applications, the 128mm SIP panel provides a dependable combination of insulation and structural support for professional builders and contractors.
