126mm Flat Roof Decking Plywood Insulation Panel 2400mm x 1200mm

Flat Roof Decking Plywood Insulation Panel with a 126mm 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 126mm thickness is suited to high-specification commercial and energy-conscious building projects.
