Exterior Trim Moulding Profile
Exterior trim moulding profiles made from high-density rigid polyurethane (150-220 kg/m³) provide weather-resistant facade decoration for windows, doors, and building cornices. Combining wood-like mechanical toughness with low weight, these trim mouldings will not crack, rot, or swell under rain, ice, or intense solar heat (-100 °C / +80 °C). Their closed-cell chemical formula keeps water absorption strictly under 1%, protecting building exteriors from moisture infiltration and thermal distortion. Pre-primed with a durable factory white acrylic technical primer, Polure exterior trim mouldings require a coat of elastic, UV-resistant facade paint for long-lasting color stability. Installation calls for clean substrate preparation, 45° precision miter cuts, continuous PU assembly adhesive along all joint surfaces, and mechanical screw fixing (silicone adhesive is strictly forbidden). Lightly sand with 180-220 grit paper prior to painting.
Frequently Asked Questions
Why is polyurethane ideal for exterior trim mouldings?
High-density polyurethane (150-220 kg/m³) offers wood-like toughness, rot-proof longevity, water absorption under 1%, and hail resistance.
What paint should be used for exterior trim moulding?
Topcoat with an elastic, UV-resistant exterior paint system. Ensure topcoat primer matches topcoat system for optimal performance.
How is exterior trim moulding installed?
Mount using a continuous bead of PU assembly adhesive along with mechanical screws. Silicone is strictly forbidden.
