Intumescent Pipe Wrap 400 Series (4hr) – to suit pipe size 82mm

For installation around plastic piping/trunking passing through fire resistant structures such as walls & doors. During the primary construction phase of projects, tolerance is in built to enable the fitting of a pipe wrap once the other services have been installed. In case of fire the intumescent material expands & crushes the pipe or trunking, sealing off this area & maintaining the integrity of the structural elements through which it passes
