The 34mm Plydeck PIR with OSB Flat Roof Insulation Board is a highly durable three-in-one roofing solution designed to combine thermal insulation, structural support, and a practical decking surface within a single panel. Manufactured with a high-performance polyisocyanurate (PIR) insulation core and a strong OSB reverse face, this board provides an efficient and reliable solution for flat roof construction.

With an excellent R-value of 1.15m²K/W and low thermal conductivity of 0.022 W/mK, the board helps reduce heat transfer and improve the energy efficiency of roof structures. The aluminium foil face enhances insulation performance and provides vapour resistance, while the OSB backing offers a durable surface suitable for decking and roofing applications.

Designed for use with flat roofs, hot bitumen systems, and decking applications, the Plydeck PIR board eliminates the need for multiple separate layers, helping simplify installation while maintaining high performance. Its robust construction and strong compressive strength make it suitable for professional roofing projects requiring reliable insulation and durability.
