A firestop sleeve suitable for both concrete floor and gypsum wall-board assembly including a layer of intumescent composite forming a moldable putty with a restraining layer, for wrapping around a pipe extending through the concrete floor or through the wall-board, along with a plurality of bendable tabs for depression into the wrapped layer to hold the restraining layer in position during installation.

Firestop sleeve

An intumescent firestop device having a layer of non-curing moldable two-stage intumescent composite and a restraining layer. When the firestop device is installed around a pipe near the wall opening through which the pipe runs, the intumescent composite exudes into the annular space between the pipe and the wall opening thereby forming a cold-gas seal. The composite is a two-stage intumescent composite that contains two different intumescent components that begin to intumesce at two different temperatures to form a hard char.
