Astro IWC Paint - Intumescent Paint for Walls and Ceilings


Astroflame IWC intumescent paint is an intumescent coating for walls and ceilings. Inherently non-combustible surfaces such as plasterboard and brick can become a potential fire hazard due to repeated redecoration with conventional paints.

Different paint types from a variety of manufacturers have generally been used over many years with less than thorough preparation. In a fire thick layers of old paint tend to de-laminate rapidly catching and spreading fire around a building. In extreme cases a lethal "flash- over" fireball effect is created.

The resultant risk to life and property can be greatly reduced at minimum cost using a combination of Astroflame IWC intumescent paint, an insulating "intumescent" barrier coating and SFR wallcoat. The Astroflame IWC intumescent paint system can help landlords comply the the Fire Safety Order 2005. Ask us for details.
