The 77mm Structural Insulated Sandwich Panel (SIP) with PIR and Plywood is a high-performance construction board designed to provide exceptional thermal insulation, structural strength, and long-lasting durability. Featuring a rigid polyisocyanurate (PIR) insulation core combined with 6mm WBP plywood facings, this panel delivers a robust and energy-efficient solution for modern construction applications.

With an excellent R-value of 2.95m²K/W and low thermal conductivity of 0.022 W/mK, the panel helps minimise heat loss and improve overall building energy efficiency. The foil-faced PIR core provides an integrated vapour control layer, helping reduce moisture movement and enhance the durability of the building structure.

Designed with a square-edge profile, the panel allows quick and accurate installation using the butt joint technique. Its strong yet lightweight construction makes it suitable for roofs, walls, floors, and general construction projects, offering builders and contractors a reliable insulated structural board solution manufactured by Custom made®.
