Gunfire is an approved contractor of Vermiculite Fire Spray. This vermiculite and portland cement based wet mix spray is for internal use on steel and concrete frames, metal floor or roof decks. It produces a coating able to withstand the thermal shocks experienced in high intensity fires and concrete structures in particular will be protected from explosive spalling when coated.
Structures that have been protected with vermiculite fire spray can provide fire resistance for up to 240 minutes and do not release toxic or hazardous fumes. A wide range of building will benefit from using sprayed cementitious fire proofing such as educational, leisure and entertainment centres, commercial and industrial projects. It is particularly useful for the fire rating upgrade of concrete soffits when buildings are changed from office to residential premises.
Structures protected with vermiculite fire spray have undergone fire resistance tests up to 240 minutes in approved independent laboratories to recognised stands BS 476: 20 – 21 1987.
As vermiculite fire spray contractors, Gunfire can work with all main contractors to provide a quick, cost effective passive fire protection solution.
