Fiberglass nets give external insulation systems the ability to inhibit the displacement of insulating material linked to temperature variations or shrinkage, thus preventing the formation of cracks on the finishing material. T-Fiberglas is a line of fiberglass nets coated with a special anti-alkaline coating, used both in external insulation systems and for the reinforcement of the cement sheaths. The line also includes the plastic angle and drip starter angle accessories.
