The FIBRANxps ETICS GF extruded polystyrene thermal insulation boards are rigid and waterproof, featuring a diamond-shaped embossed surface on both sides for improved adhesion of mortars, coatings, and adhesives.

They are produced by extruding polystyrene foam and have a very dense and closed cellular structure. The microscopic fine, rigid, and closed polystyrene cells contain trapped inert gas and air, achieving very high insulation capability. Additionally, they remain dry in moist environments.

They are certified by international independent institutes and carry the CE marking. They offer extremely high mechanical strengths, are waterproof, and have balanced resistance to water vapor diffusion.
