Exterior Eave Cornice
Polure exterior eave cornices deliver architectural elegance and weatherproofing along rooflines, soffits, and exterior facades. Precision-molded from high-density rigid polyurethane (150-220 kg/m³), these cornices provide wood-like mechanical durability while remaining light enough for easy overhead installation. Their closed-cell structural composition limits water absorption below 1%, making them fully immune to rot, swelling, mold, and ice expansion under eaves. Engineered to endure harsh weather and temperatures from -100 °C / +80 °C without warping or shrinking, they carry a certified B2 fire rating. Arriving factory-pre-primed with a white acrylic technical primer, installation requires clean surface preparation, continuous polyurethane assembly adhesive, and mechanical screw fixings. Finish with elastic, UV-resistant exterior paint.
Frequently Asked Questions
What material is used in Polure exterior eave cornices?
Polure exterior eave cornices are manufactured from high-density rigid polyurethane (150-220 kg/m³), combining wood-like toughness, B2 fire rating, and lightweight handling.
Are exterior eave cornices immune to rain and freezing ice?
Yes, water absorption is under 1% (closed-cell matrix) and they tolerate -100 °C / +80 °C without rotting or cracking.
How do you install an exterior eave cornice?
Apply continuous PU assembly adhesive along wall and join edges, and secure with countersunk mechanical screws. Silicone is forbidden.
What paint finish is required for exterior eave cornices?
They arrive pre-primed with white acrylic primer and must be painted with an elastic, UV-resistant exterior paint to prevent UV fading.
Do exterior eave cornices dent during hail storms?
No, high-density polyurethane (150-220 kg/m³) provides wood-like structural strength, preventing hail impact damage unlike EPS foam.
