The 148mm PIR and OSB SIP Structural Insulated Sandwich Panel is a high-performance construction board designed to deliver exceptional thermal insulation, structural strength, and long-term durability for advanced building applications. Manufactured with a rigid polyisocyanurate (PIR) foam core combined with two 9mm OSB facings, this panel provides a robust and energy-efficient solution for modern 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 offers excellent insulation performance while maintaining strong structural stability. The foil-faced PIR core provides an integrated vapour control layer, helping reduce moisture movement and improve the long-term protection of the building structure.

Featuring a square-edge profile, the panel allows precise and efficient installation using the butt joint technique. Suitable for roofs, walls, floors, and general construction applications, the 148mm SIP panel provides builders and contractors with a reliable high-performance OSB structural insulated panel solution.
