Current building practices have resulted in non fire-rated cavity penetrations. The risk here is that, in a compartment fire incident, smoke and heat will quickly ingress through the penetrations and into the wall cavities.Several recent fires have seen buildings quickly destroyed as the smoke and heat has spread rapidly, vertically and laterally, unhindered through the building's cavities.
The Twintherm© range of penetrations protectors are ideal for all vents that pass through the outer walls of buildings. Whether for boiler flues, extraction fans or just simply air vents, these 'sleeves' will ensure the smoke, heat and flames exhaust directly into the outer atmosphere.
Installation is straightforward with minimal disruption
Twintherm's© window and door protect the void between the inner and outer 'skins' of a building's outer walls from ingress by smoke, heat and flames. Sealed internally and externally.
Twintherm's intelligent Deflector will add further protection to the cavities between the building's outer wall and any rainscreen cladding.
Whatever the nature of the cladding attached to a building's facades, Twintherm's A1 fire-rated deflector will protect it from the heat, smoke and flames a fire produces.
