The FF-PIR 40/70 GYL panel consists of a 30/60 mm thick PIR polyurethane panel and a 9 mm thick gypsum board with tapered edges, which is glued on to one side of the panel at our plant. The panels have a rabbet groove on the longer sides with a flat edge at the ends. The FF-PIR 40/70 GYL insulation panels are designed for providing internal supplementary thermal insulation. FF-PIR 40/70 GYL provides effective supplementary thermal insulation in walls and roofs, which makes it possible to significantly reduce the insulation thickness. Particularly in renovation projects, this allows for maximal utilization of living space without thick insulation. FF-PIR 40/70 GYL products are suitable for both renovation and new construction applications. Dimension 600*2600mm
