EZBarrier Enclosure Prevents Fire From Escaping

The EZBarrier enclosure has been designed to prevent fire, gas, smoke and heat from escaping and traveling into the ductwork. In the event of a fire, the 3M™ intumescent lining in the enclosure expands up to five times its original size to contain the fire, gas, smoke and heat. In addition, a 3M intumescent lined metal ring is installed around the PVC duct extension pipe. As the PVC pipe melts, the intumescent lining in the ring expands to com- pletely seal off the hole in the enclosure and prevent the leakage of fire, gas, smoke and heat into the ductwork.
