The 112mm Structural Insulated Sandwich Panel (SIP) with PIR and Plywood is a high-performance construction board designed to provide exceptional thermal insulation, structural stability, and long-lasting durability. Manufactured with a rigid polyisocyanurate (PIR) insulation core combined with 6mm WBP plywood facings, this panel offers an advanced solution for energy-efficient construction projects requiring reliable insulation and strength.

With an impressive R-value of 4.55m²K/W and a low thermal conductivity of 0.022 W/mK, the panel delivers excellent thermal performance by reducing heat transfer and improving 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 simple and accurate installation using the butt joint technique. Its durable yet lightweight construction makes it suitable for roofs, walls, floors, and general construction applications, providing contractors and builders with a high-performance insulated structural panel manufactured by Custom made®.
