The Envirograf Intumescent Protection Sleeve System For Cables unit can retrofit existing electrical and plumbing that passes through a fire barrier in walls and floors, protecting against fire and smoke spreading.
The intumescent tube is available in 2 different lengths and can be cut to fit the required depth between walls and floors. The tube can also be cut to fit around existing pipes and cables, adhered with the self-adhesive tag before being pushed into the wall. During a fire, the intumescent tube expands to seal off the gap to fire and smoke.
