The 38mm SIP Structural Insulated Sandwich Panel with PIR and OSB is a high-performance construction board designed to provide effective thermal insulation, structural support, and long-lasting durability for modern building applications. Manufactured with a rigid polyisocyanurate (PIR) insulation core combined with a strong 9mm oriented strand board (OSB) facing, this panel offers a reliable and efficient solution for energy-conscious construction projects.

With an R-value of 0.91m²K/W and a low thermal conductivity of 0.022 W/mK for the PIR core, the panel helps reduce heat transfer and improve overall building energy efficiency. The foil-faced PIR core provides an integrated vapour control layer, helping minimise moisture movement and protect the structure over time.

Featuring a square-edge profile, the panel allows easy and accurate installation using the butt joint technique. Its durable construction and strong OSB facing make it suitable for roofs, walls, floors, and general construction applications, providing builders and contractors with a dependable high-performance OSB SIP panel manufactured by Custom made®.
