Polyurethane Ceiling Dome
Polure polyurethane ceiling domes provide dramatic architectural depth, recessed central light wells, and elegant classical ceiling framing for chandeliers and indirect LED lighting. Molded from high-density rigid polyurethane (150-220 kg/m³), these structural ceiling inserts combine wood-like mechanical rigidity with a lightweight profile that will not stress ceiling joists or drywall structures. Incorporating a closed-cell physical structure with water absorption under 1%, they will not warp, swell, rot, or cultivate mold in humid indoor atmospheres. Certified B2 fire class, they remain stable across temperatures from -100 °C / +80 °C. Factory-coated in a white acrylic primer, each dome accepts topcoat paints seamlessly. Installation requires a continuous bead of polyurethane assembly adhesive combined with mechanical screw fasteners.
Frequently Asked Questions
What material is the Polure polyurethane ceiling dome manufactured from?
Polure polyurethane ceiling domes are manufactured from high-density rigid polyurethane (150-220 kg/m³), ensuring B2 fire class safety and lightweight structural durability.
Can polyurethane ceiling domes be installed in humid indoor environments?
Yes. Water absorption is under 1%, preventing swelling, rot, or mold growth in bathrooms and indoor pools.
What adhesive is required to install a polyurethane ceiling dome?
Continuous polyurethane assembly adhesive must be applied along rim contact faces with mechanical screw fixings. Silicone adhesive is forbidden.
How should polyurethane ceiling domes be prepared prior to painting?
Lightly sand the factory white acrylic primer with 180-220 grit sandpaper to remove residue, then apply two coats of ceiling paint.
