Exterior Cornice Profiles
Polure exterior cornice profiles enhance rooflines and facade eaves with grand architectural framing and weather-resistant durability. Engineered from high-density rigid polyurethane (150-220 kg/m³), these profiles offer the solid appearance of traditional stone or heavy timber cornices without introducing excess structural weight. Their closed-cell structure maintains water absorption strictly below 1%, making them immune to rain, frost, rot, and insect damage. Operable without shrinkage or distortion across extreme climate spans from -100 °C / +80 °C (B2 fire safety rating), each piece arrives pre-coated with a technical white acrylic primer. Installation requires dual-securing: continuous polyurethane assembly adhesive on contact edges plus mechanical countersunk screws.
Frequently Asked Questions
What density is used for Polure exterior cornice profiles?
Polure exterior cornice profiles are produced from high-density rigid polyurethane (150-220 kg/m³), providing wood-like physical strength.
Can exterior cornice profiles withstand extreme winter freezing and summer heat?
Yes, they operate distortion-free between -100 °C / +80 °C and will not shrink, warp, or crack in hail.
What paint must be applied to exterior cornice profiles?
Outdoors, they must be painted with an elastic, UV-resistant exterior topcoat paint applied over the factory acrylic primer.
What mechanical fastening is required for exterior cornice profiles?
Profiles must be glued with polyurethane assembly adhesive AND fastened with countersunk screws. Outdoor joint seams must also be screwed together.
