Crystal chandelier

A crystal chandelier is a ceiling-mounted lighting fixture combining crystal or cut-glass elements with a metal frame. Typically installed at the center of ceilings in spaces with high clearance—such as living rooms, halls, stairwells, and atriums—it delivers elegant ambient lighting. Installation employs a polyurethane ceiling rose (density 150–220 kg/m³) that frames the chandelier's mounting point and conceals wiring and fixtures. This polyurethane rose is significantly lighter than plaster, enabling single-person installation and ceiling mounting without structural burden. Its closed-cell structure achieves water absorption below 1%, providing excellent resistance to moisture-related degradation. Unlike plaster, polyurethane resists shipping damage and post-installation cracking or warping. Cast from molds, the rose can be custom-manufactured to suit various chandelier diameters and designs, arrives factory-primed, and can be finished in any desired color.
