Exterior Molding Details
Polure exterior molding details enrich building facades, window surround pediments, and roof eaves with crisp classical architectural profiles. Engineered from high-density rigid polyurethane (150-220 kg/m³), these exterior trims feature exceptional impact resistance and mechanical toughness, surpassing EPS foam in hail and impact weather conditions. Closed-cell polymer construction guarantees water absorption below 1%, rendering profiles immune to rot, swelling, mold, and freeze-thaw cracking from -100 °C / +80 °C. Supplied with a white factory acrylic primer, they must be painted with UV-resistant facade paint to prevent outdoor yellowing. Installation involves applying continuous polyurethane assembly adhesive on wall contacts and joints, accompanied by mechanical screw anchors. Fill screw holes and seams with facade acrylic putty, sand with 180-220 grit paper, and apply two coats of exterior paint.
Frequently Asked Questions
What density material is used in Polure exterior molding details?
Polure exterior molding details are produced from high-density rigid polyurethane (150-220 kg/m³), resisting hail denting unlike EPS foam.
Are exterior molding details affected by freezing weather?
No, with water absorption below 1% and a temperature range of -100 °C / +80 °C, they do not crack or deform in freezing conditions.
What adhesive should be used for installing exterior molding details?
Polyurethane assembly adhesive must be applied along all wall contacts and joint edges. Silicone adhesives are forbidden.
Is mechanical screw fixing mandatory for exterior molding details?
Yes, dual attachment combining continuous polyurethane adhesive with mechanical screws anchored into the facade is required.
Why must exterior molding details be painted outdoors?
Painting with UV-resistant exterior paint protects the factory white primer and prevents polyurethane yellowing under sunlight.
