Polyurethane Window Surround
Polure polyurethane window surrounds deliver complete architectural framing sets incorporating sills, side moldings, and pediments designed to transform exterior window openings. Molded from high-density rigid polyurethane (150-220 kg/m³), these exterior surround profiles provide wood-like mechanical strength and high impact durability, protecting window reveals from wind and rain. Their closed-cell structural body retains water absorption strictly under 1%, ensuring they will never rot, warp, swell, or harbor mold under heavy rain, freeze-thaw winter cycles, or intense sun exposure. Rated B2 for fire safety and stable from -100 °C / +80 °C, each surround piece comes factory pre-primed with white acrylic technical primer and requires painting with UV-resistant exterior facade paint. Installation requires dual fastening using polyurethane assembly adhesive and mechanical screws.
Frequently Asked Questions
What is included in a Polure polyurethane window surround set?
A polyurethane window surround set consists of architectural exterior moldings, sill elements, and top pediments designed to frame window openings.
Are Polure polyurethane window surrounds load-bearing?
No, Polure polyurethane window surrounds are strictly decorative facade framing elements.
What material density is used for polyurethane window surrounds?
They are molded from high-density rigid polyurethane (150-220 kg/m³), providing wood-like physical durability and sharp relief detailing.
How are polyurethane window surrounds protected against weather and sun?
Their closed-cell structure keeps water absorption under 1%. After installation with PU adhesive and screws, they must be painted with elastic UV-resistant exterior paint.
Can silicone adhesive be used to mount polyurethane window surrounds?
No, silicone adhesive is strictly forbidden because it lacks structural bonding capability. Only polyurethane assembly adhesive paired with mechanical screws must be used.
