ABSTRACT:
An intumescent composite comprising a layer of intumescent sheet material having a restraining layer laminated thereto provides a superior intumescent barrier for use in sealing penetrations through floors, partitions and ceilings from smoke, fire, gas and water passage. The restraining layer causes the intumescent reaction to be generated in a directionalized manner and can be utilized to assure that the penetration cavity is optimally filled. The intumescent composite can have holes punched in it and can be used in fire protection applications where air circulation is desired. In the event of a fire, the expansion of the intumescent composite is in a direction which enable the punched holes to be quickly filled.
