Vermiculite fire spray is an inexpensive form of fire protection that provides up to 240 minutes of protection to structural steel, ceilings and ducts.
Vermiculite is quite often a cheaper option than intumescent coatings at FRLs of 90 or 120 minutes.
Vermiculite retains moisture that is released as steam in the event of a fire. The ensuing cooling effect delays the temperature increase of the steel providing a level of protection.
Whilst vermiculite is inexpensive, both in terms of material cost and application, it doesn't provide the aesthetically pleasing qualities of intumescent coatings.
