High Ceiling Coving Moulding
Polure high ceiling coving mouldings feature prominent projections designed to balance grand proportions in tall rooms and entry halls. Engineered from high-density rigid polyurethane (150-220 kg/m³), these large-scale coving profiles possess wood-like physical durability while avoiding structural weight. Closed-cell polymer density keeps water absorption strictly under 1%, safeguarding against humidity, rot, and swelling. Fire safety class B2 rated and resistant to temperature shifts from -100 °C / +80 °C, each length comes factory-primed with white acrylic coating. Installation requires accurate 45° miter cuts, continuous polyurethane assembly adhesive, countersunk mechanical screws, joint filling, and topcoat painting.
Frequently Asked Questions
What density material is used for Polure high ceiling coving mouldings?
They are molded from rigid high-density polyurethane (150-220 kg/m³).
Are high ceiling coving mouldings suitable for humid environments?
Yes, water absorption under 1% prevents swelling, rot, or mold in moist areas.
What fastening system is needed for large high ceiling coves?
A dual fastening system combining continuous PU assembly adhesive and countersunk mechanical screws.
Is silicone adhesive permitted for installation?
No, silicone adhesive is strictly forbidden; specialized polyurethane assembly adhesive is required.
