Envirograf Intumescent Pipe Covers protect pipes, cables, wires and other services that lay close to surfaces such as ceiling, walls and floors where regular fire wraps and collars are unable to be fitted. These pipe covers simply fit over an area, whether flat or in a corner, and screwed into place. Use to cover 1 or more services at once. Each cover is lined with intumescent material which expands during fire.

2 shapes of pipe covers are available; a 'U' shape for flat surfaces and a 'C' design for covering services in tight corners. 2 different depths offer 2 hour fire protection (50mm) and 4 hours (100mm).


The intumescent pipe covers simply fit over the services and they are then fixed with screws. U-shaped pipe covers are available for open areas, and special h-shaped units are available for application in difficult corners.
