Fiberglass mesh for reinforcing facade coatings on thermal insulation systems. It has 4x4mm frame opening and weighs160gr/m2. Distinguished for its resistance to alkaline environments. Offers significant structural reinforcement and prevents capillary cracks resulting from temperature variations. The use of DUROSTICK DS-4160 with the external thermal insulation composite system for buildings, THERMOSEAL (ETICS) is imperative. The reason being that the surface coatings are affected by particular stresses. Primarily because the solar heat cannot be defused backwards because of the insulating boards. Any additional stresses created are due to the existence of many joints between the insulation boards.
