Firestop Pillows are designed for firestopping medium to large openings
containing various penetrating items such as pipes, conduits, cables,
insulated metal pipes, bus ducts and HVAC ducts. Pillows are
particularly well suited for applications involving data,
communications, power or control cables, innerducts and cable trays.
This method of sealing offers easy retrofitting of cable installations
without the need to damage the firestop seal. Difficult applications
such as one-sided shaft wall installations and other applications where
access is restricted to one side of the assembly may be easily
firestopped with this material.
