Abstract
The insulation barrier is formed of a body of foamed polystyrene, either expanded or extruded, which is provided with a protective coating formed of a metallic-based inorganic material and is applied over at least one surface of the body. Optionally, a fire resistant composition of any inorganic silicate, boric acid, any salts of boric acid, hydrated sodium borate (borax) or mixtures thereof, and preferably sodium silicate, is applied in solution form and maintained within the body by a wetting agent in the solution. The protective coating is being applied by a coating roller followed drying of the polystyrene body.
