The FIBRANxps ETICS GF extruded polystyrene insulation boards are hard and waterproof with an embossed diamond-shaped pattern surface (waffle) on both sides for better adhesion of mortars, coatings, and adhesives.

The FIBRANxps ETICS GF extruded polystyrene boards are produced through the extrusion of polystyrene foam and have a very dense, closed microcellular structure. The microscopic, fine, hard, and closed polystyrene cells contain trapped inert gas and air, achieving very high insulating capacity, while remaining dry in humid environments.

They are certified by international independent institutes and bear the CE marking. It is the only insulating material that offers exceptionally high mechanical strength, is waterproof, and has balanced resistance to water vapor diffusion.
