Recessed Ceiling Dome
Polure recessed ceiling domes create dramatic focal depth and grand architectural elegance above chandeliers, dining halls, and foyer ceiling layouts. Precision-molded from high-density rigid polyurethane (150-220 kg/m³), each dome offers structural resilience and sharp ornamental detail while remaining lightweight to eliminate structural ceiling stress. The closed-cell material maintains water absorption below 1%, resisting humidity, warping, and mold in indoor spaces or covered outdoor porticos. Capable of withstanding extreme thermal shifts between -100 °C / +80 °C and rated Class B2 for fire safety, the dome comes pre-coated with factory white acrylic primer. Installation into the framed ceiling opening requires applying a continuous bead of polyurethane assembly adhesive on contact edges (silicone is strictly forbidden) combined with countersunk mechanical screws into framing joists. Screw heads and perimeter joints are filled with acrylic filler, lightly sanded with 180-220 grit sandpaper, and finished with two coats of interior paint.
