FIRE STOP: Passive fire protection in the unventilated facade

Firetight is a specially developed solution for airtight sealing of cavity walls in buildings, which also immediately makes the cavity fire-retardant. Firetight can make rooms in buildings fire-retardant sealed, so that a potential fire cannot simply spread to adjacent areas.

Firetight can be used anywhere in a building, where the cavity between floors, walls and facades must be able to withstand a fierce and expanding fire for a longer period of time.
Firetight prevents fire spreading between different floors in high buildings, such as residential towers, hospitals, offices, etc.

Firetight Fire Stop

Application

The Fire Stop consists of a vacuum-sealed strip of high-density Rockwool Premium wrapped in a PE foil vapor-barrier, with an added intumescent fire-retardent strip. fter placing and puncturing the vacuum foil, the wool expands and the Fire Stop completely fills the entire space. The product self-fixates itself in the cavity without the use of fasteners or glue. Designed for easy installation and disassembly.

With wide cavities, instead of a single row of Firetight, one can use double row Firetight to fill the space. The realized connection is thermally insulated, airtight and fire resistant for three to four hours.

The FIRETIGHT Fire Stop is available for the following cavity widths:
