by Through our CAFCO brand, we offer a complete line of intumescent fireproofing coatings for structural steel, for both interior and exterior use. Intumescent coatings are applied similar to paint. These coatings expand under fire to form an insulating char layer that protects the structural steel underneath.
Intumescent coatings are ideal when the design calls for exposed structural steel as an aesthetic feature of the building. With the SprayFilm line of intumescent coatings, structural steel no longer needs to be hidden behind ceilings and gypsum board.
