DuraVision polycarbonate mirrors from Norix are designed specifically for the harsh conditions found in intensive-use environments. The strength of polycarbonate combined with a solid, full foam backing and a unique steel frame design ensures these mirrors are the sturdiest, most tamper-resistant mirrors on the market, according to the company. Most convex mirrors in commercial establishments are made from acrylic. When tested to withstand impact, they’ll be the first to break into knife-like shards, but the DuraVision polycarbonate mirrors, with pure reflective silver sealed in layers of protective coatings, are premium 3 mm grade with a tensile strength of 9,400 psi. When used in cells and other critical locations, the mirrors permit staff the opportunity to observe blind corners and intersections without putting themselves or others in harms way.
