ABSTRACT:
A fire protective insulating device adapted to be placed about articles to be protected from fire. The device comprises at least one layer of resilient and compressible insulative material having a plurality of compressive fastener means for mechanically compressing the insulative material to a high density, at least a portion of the fastening material being substantially less resistive to high temperature than the insulative material. A scrim means may be wrapped about the outside of the compressed insulative material for retaining the compressed insulative material. At least a portion of the scrim means is also preferably constructed of a material which is substantially less resistive to high temperature than is the insulative material. Upon contact with high temperature, the structural integrity of the fastening means is decreased allowing the compressed insulative material to mechanically expand. The insulating device may be performed in a boxlike or in a boot type configuration, one end of the insulating device being adapted to be opened in order to be positioned about a motor or other object to be protected from fire, said end being adapted to then be sealed in order to isolate the object to be protected from fire.
