The 138mm PIR and OSB SIP Insulated Sandwich Panel is a high-performance construction board designed to provide exceptional thermal insulation, structural strength, and long-term durability for modern building projects. Manufactured with a rigid polyisocyanurate (PIR) foam core combined with two 9mm OSB facings, this panel offers a strong and energy-efficient solution for a wide range of construction applications.

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 reliable structural integrity. The foil-faced PIR core provides an integrated vapour control layer, helping reduce moisture movement and improve the overall durability of the building structure.

Featuring a square-edge profile, the panel allows accurate and efficient installation using the butt joint technique. Suitable for roofs, walls, floors, and general construction applications, the 138mm SIP panel provides builders and contractors with a dependable high-performance OSB structural insulated panel solution.
