PTEROFLAT XT Solid PC Sheets are unbreakable, transparent polycarbonate sheets. Thanks to their exceptional strength and heat resistance, they are the perfect solution for any outdoor application requiring extra power and durability. They are highly stable under outdoor weather conditions. Due to their resistance to UV radiation, they show no significant change in their properties even after years of exposure to sunlight. To prevent the risk of permanent adhesion caused by sunlight, the protective film must be removed immediately after outdoor installation.
