Polyurethane Ceiling Light Frame
Designed for modern lighting arrangements, polyurethane ceiling light frames combine architectural beauty with exceptional durability. Made from high-density rigid polyurethane (150-220 kg/m³), these ceiling fixtures offer wood-equivalent mechanical strength while being lightweight and non-deformable. Their closed-cell micro-structure guarantees water absorption under 1%, preventing mold, swelling, or rotting even when installed in humid microclimates or covered outdoor soffits (-100 °C / +80 °C). Each ceiling light frame comes pre-treated with a factory white acrylic technical primer, ready to be painted with standard interior or exterior paints. Installation requires clean, dry surfaces, 45° miter cuts using a fine-tooth saw, continuous application of PU assembly adhesive, and mechanical screw fixing (silicone adhesive is forbidden). Lightly sand the surface with 180-220 grit paper prior to painting to eliminate mold release agent residue.

Frequently Asked Questions
What are the benefits of polyurethane ceiling light frames?
Polyurethane ceiling light frames (150-220 kg/m³) are lightweight, impact-resistant, 100% moisture-proof, and will not warp or crack over time.
Can LED strip lighting or spotlights be integrated into the frame?
Yes, polyurethane is flame-retardant (fire class B2) and withstands temperatures up to +80°C, making it safe for LED lighting fixtures.
How is a polyurethane ceiling light frame mounted?
Mount using a continuous bead of PU assembly adhesive combined with countersunk screws. Silicone is forbidden as it lacks adhesive strength.
What paint should be applied to polyurethane ceiling light frames?
Use water-based, synthetic, or acrylic topcoats. Ensure the topcoat brand matches the primer system brand for maximum paint durability.
