Weatherproof Building Trim
Polure weatherproof building trim provides exterior architectural detailing built to withstand harsh weather, rain, frost, and intense heat. Molded from high-density rigid polyurethane (150-220 kg/m³), this facade trim offers stone-like toughness while remaining lightweight for easy installation on building exteriors. Its closed-cell physical core maintains a water absorption rate strictly below 1%, making it completely resistant to freeze-thaw cracking, rot, and mold. Rated for B2 fire class safety and thermally stable between -100 °C / +80 °C, each piece comes pre-coated with factory white acrylic primer. Installation requires clean, dry substrate surfaces and precise 45-degree miter joints. Apply a continuous bead of polyurethane assembly adhesive on mounting faces and join edges; silicone sealant is strictly prohibited. Mechanical screw fixing is mandatory for exterior safety; screw heads and joints are filled with facade filler, sanded smooth with 180-220 grit paper, and painted with elastic UV-resistant exterior paint.
Frequently Asked Questions
What material is Polure weatherproof building trim crafted from?
It is crafted from high-density rigid polyurethane (150-220 kg/m³), offering high impact resistance and a B2 fire safety rating.
Will weatherproof building trim warp or crack in winter temperatures?
No. It is thermally stable from -100 °C / +80 °C with water absorption under 1%, preventing freeze-thaw distortion and cracking.
How is weatherproof building trim installed on exterior walls?
Apply continuous polyurethane assembly adhesive paired with mechanical screw fixing. Silicone is strictly forbidden. Fill screw heads with facade putty and sand.
What paint must be used for exterior weatherproof building trim?
Outdoor installations must be painted with an elastic, UV-resistant exterior paint over the factory white primer to prevent weathering.
