FIRSTO - multi-cable and cable-tray firestop penetrations
FIRSTO firestops are designed to seal multi-cable and
cable tray penetrations of fire-rated walls and floors.
FIRSTO
firestops have a modular composition. Ducting additional cables is
extremely simple when using FIRSTO.
FIRSTO utilizes a metal frame that encompasses the entire cable run
or the cable tray with cable at the point of penetration.
The FIRSTO firestop consists of a metal
enclosure, a set of ACTIFOAM sheets for the fire safe filling and a set of gaskets.
ACTIFOAM has a closed cell structure so that it cannot
absorb any moisture. Therefore this foam rubber is not only fire
resistant but also has excellent thermal insulation properties.
ACTIFOAM is based on ACTIFIRE technology:
invented by BEELE Engineering/CSD International.
The ACTIFIRE technology was developed specifically to allow
mechanical loads on the construction caused by fire to be absorbed. This technology is designed to enable the sealant
materials used to perform an active and fire-resistant function during a fire.
This function is not achieved by volume expanding (intumescent) materials, whose surface structure
swells during fire and thereby provides thermal insulation for the
materials behind, but materials that when exposed to high temperatures
or fire will produce new fire retardant material (in large volume).
