The 39mm Plydeck PIR with OSB Flat Roof Insulation Board is a highly durable three-in-one roofing solution designed to provide superior insulation, structural support, and a ready-to-use decking surface in a single panel. Manufactured with a high-performance polyisocyanurate (PIR) insulation core and a strong OSB reverse face, this board delivers excellent thermal performance and reliable durability for flat roof applications.

With an R-value of 1.37m²K/W and low thermal conductivity of 0.022 W/mK, the board helps minimise heat transfer and improve the energy efficiency of roof structures. The aluminium foil face enhances insulation performance while providing vapour resistance, and the OSB backing creates a strong and stable surface suitable for decking and roofing systems.

Suitable for flat roofs, hot bitumen applications, and decking systems, the Plydeck PIR board combines multiple roofing functions into one efficient product. Its robust construction and 150 kPa compressive strength make it a dependable choice for professional roofing installations requiring insulation and structural performance.
