Rigid PU Crown Molding
Polure rigid PU crown moldings deliver crisp, unyielding architectural lines at ceiling junctions in both modern and classic interiors. Molded from high-density rigid polyurethane (150-220 kg/m³), these moldings offer high mechanical impact resistance without heavy structural weight. Their closed-cell structural composition limits water absorption below 1%, making them fully immune to rot, swelling, mold, and humidity in kitchens and bathrooms. Capable of withstanding temperatures from -100 °C / +80 °C without warping or shrinking, they feature a B2 fire safety rating. Delivered factory-pre-primed with a smooth white acrylic technical coat, installation requires fine-saw miter cutting, continuous polyurethane assembly adhesive, and mechanical screw fixings.
Frequently Asked Questions
What material is used in Polure rigid PU crown moldings?
Polure rigid PU crown moldings are manufactured from high-density rigid polyurethane (150-220 kg/m³), combining impact resistance, B2 fire rating, and lightweight handling.
Can rigid PU crown moldings be installed in humid bathrooms?
Yes, water absorption is under 1% and they will not rot, swell, or cultivate mold in wet environment conditions.
How do you install a rigid PU crown molding?
Cut 45° miters with a fine-tooth saw, apply continuous PU assembly adhesive on contact edges, and secure with countersunk screws. Silicone is forbidden.
Are rigid PU crown moldings suitable for outdoor eaves?
Yes, they tolerate -100 °C / +80 °C. Outdoor application requires painting with elastic, UV-resistant exterior paint.
What paint finish works best on rigid PU crown moldings?
They arrive pre-primed. Lightly sand and apply water-based or synthetic paints indoors, or UV-resistant exterior paint outdoors.
