Waterproof Ceiling Dome
Polure waterproof ceiling domes add dramatic architectural height and recessed lighting elegance to luxury bathrooms, indoor pools, and humid spa environments. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these domes feature a closed-cell physical structure with water absorption under 1%, guaranteeing that they will never warp, swell, rot, or degrade in moisture. With a fire safety rating of B2 and thermal tolerance from -100 °C / +80 °C, they combine structural resilience with lightweight ease of installation into drywall or drop ceiling openings. Factory-pre-primed with white acrylic primer, installation requires continuous polyurethane assembly adhesive on contact rims and countersunk mechanical screws.

Why are Polure waterproof ceiling domes ideal for indoor pools and bathrooms?
Polure waterproof ceiling domes feature a closed-cell polyurethane structure with water absorption under 1%, preventing rot, swelling, and mold growth in wet spaces.
What temperature extremes can a waterproof ceiling dome endure?
They remain completely stable between -100 °C / +80 °C without shrinking or distorting.
How is a waterproof ceiling dome installed into the ceiling?
Apply continuous PU assembly adhesive along all outer rim contact surfaces, anchor with mechanical countersunk screws into ceiling framing, fill joints, and paint.
Can silicone adhesive be used to mount a waterproof ceiling dome?
