Indirect Light Luminaire Moulding
Indirect light luminaire mouldings crafted from high-density rigid polyurethane (150-220 kg/m³) create soft, ambient architectural lighting solutions for ceilings and walls. Designed to conceal LED strips while casting uniform reflected light, these profiles maintain structural integrity without sagging or warping under thermal variation (-100 °C / +80 °C). Their closed-cell construction makes them 100% moisture resistant with water absorption under 1%, expanding their use to humid bathrooms, spa areas, and exterior building eaves. Pre-primed with a factory white acrylic primer, Polure indirect light luminaires accept all water-based, acrylic, or synthetic paints. Installation requires clean, dry surfaces, mitering at 45° with a fine saw, a continuous bead of PU assembly adhesive, and mechanical countersunk screws (silicone adhesive is strictly forbidden). Lightly sand with 180-220 grit paper prior to final coat application.
Frequently Asked Questions
How does an indirect light luminaire moulding work?
It conceals LED light strips within a specially designed polyurethane channel, projecting smooth reflected glow across ceilings or walls.
Is polyurethane heat resistant enough for continuous LED lighting?
Yes, high-density polyurethane (150-220 kg/m³) withstands temperatures up to +80°C and features B2 fire safety classification.
Can indirect light luminaire mouldings be used in bathrooms?
Absolutely. With water absorption under 1%, they will not warp, swell, rot, or attract mold in wet or humid interior environments.
What adhesive should be used for installing indirect light luminaires?
Always use a high-tack PU assembly adhesive along with mechanical screw fixings. Silicone is strictly forbidden.
