Mirror, silver-backed (3mm, 4mm, 6mm)
High-quality reflective glass with 92-95% light reflectance, consisting of float glass with silver coating, copper layer, and protective paint backing. Available in 3mm, 4mm, and 6mm thicknesses.
High-quality reflective glass with 92-95% light reflectance, consisting of float glass with silver coating, copper layer, and protective paint backing. Available in 3mm, 4mm, and 6mm thicknesses.
Silver-backed mirrors are manufactured from float glass coated with a thin layer of silver (50-100nm) through chemical deposition, protected by a copper layer and dual-coat paint system. The silver provides excellent reflectivity while the copper and paint layers protect against corrosion and mechanical damage. Compliant with AS/NZS 2208:1996 for safety applications when vinyl-backed.
