Polyurethane Dome
Polure polyurethane domes infuse interior ceilings with grand spatial depth and classic architectural refinement. Engineered from high-density rigid polyurethane (150-220 kg/m³), each dome offers high structural durability and detailed ornamental relief while maintaining a lightweight footprint that eliminates ceiling stress. The closed-cell polymer structure keeps water absorption strictly under 1%, preventing swelling, rot, or mold growth in damp conditions. Resistant to thermal variations between -100 °C / +80 °C and rated Class B2 for fire safety, the dome arrives pre-coated with factory white acrylic primer. Installation into framed ceiling openings requires a continuous bead of polyurethane assembly adhesive on contact edges—never silicone—and countersunk mechanical screws into ceiling joists. Screw heads are filled with acrylic filler, lightly sanded with 180-220 grit paper, and finished with two coats of interior paint.
Frequently Asked Questions
What density material is used in the Polyurethane Dome?
The Polyurethane Dome is manufactured from high-density rigid polyurethane (150-220 kg/m³), ensuring strength and sharp detail.
Can the Polyurethane Dome withstand moisture?
Yes, with water absorption below 1%, it will not warp, rot, or mold in high-humidity areas.
What adhesive should be used to install the Polyurethane Dome?
Use polyurethane assembly adhesive combined with mechanical screws. Silicone adhesive is strictly forbidden.
How is the Polyurethane Dome painted?
Fill screw holes with acrylic putty, sand smooth with 180-220 grit paper, and apply two coats of water-based or synthetic paint.
