Most convex commercial safety mirrors you see in commercial establishments and at intersections are made from acrylic. When tested to withstand impact, they’ll be the first to break into knife-like shards. Our DuaVision mirror system, with pure reflective coating, is premium 3mm grade with tensile strength of 9,400 psi. To further enhance the strength, we completely fill the DuraVision mirror’s cavity behind the mirror with high-density water blown urethane foam to limit the compression distance, thus eliminating the possibility of breakage from a severe blow. To make sure they stay in place, the DuraVision mirror perimeter is fully enclosed in a heavy duty powder coated steel frame that sits flush with the wall and ceiling and features countersunk screw holds to receive tamper-resistant fasteners.
