81mm Flat Roof Decking Plywood Insulation Panel 2400mm x 1200mm

Flat Roof Decking Plywood Insulation Panel with an 81mm thickness and 2400mm x 1200mm sheet size. This composite insulation deck combines a rigid PIR (polyisocyanurate) insulation core bonded to a 6mm plywood facing, creating a durable, thermally efficient substrate for flat roof construction. The PIR core delivers low thermal conductivity for effective heat retention, while the plywood top layer provides a stable, load-bearing surface for direct membrane application. Designed for warm roof systems, it offers rapid installation and long-term dimensional stability. The 81mm thickness provides enhanced insulation for improved U-values in flat roof build-ups without additional layers.
