Polure Window Pediments
Polure window pediments add refined architectural pediment crowns to residential and commercial window surrounds. Precision-molded from high-density rigid polyurethane (150-220 kg/m³), these window pediment profiles deliver timber-matching mechanical strength and fine detail retention while eliminating cracking or warping. Featuring a closed-cell polymer structure with water absorption under 1%, they offer complete moisture resistance and mold protection in both indoor and outdoor window applications. Operating reliably across temperatures from -100 °C / +80 °C with Class B2 fire safety certification, each pediment comes factory pre-coated with white acrylic primer. Installation onto window head surrounds requires applying a continuous bead of polyurethane assembly adhesive on rear contact faces (silicone is strictly forbidden), combined with countersunk mechanical screw anchors. Fill screw recesses and joint lines with acrylic putty, sand smooth with 180-220 grit paper, and finish with two coats of paint.
Frequently Asked Questions
What density material is used in Polure Window Pediments?
Polure Window Pediments are molded from high-density rigid polyurethane (150-220 kg/m³), offering wood-like impact strength.
Will Polure Window Pediments rot or mold in humid conditions?
No, with water absorption strictly under 1%, they will never rot, warp, or cultivate mold.
What adhesive should be used for installing Polure Window Pediments?
Always use polyurethane assembly adhesive across back contact faces and joining edges, combined with screws. Silicone is strictly forbidden.
How do you prepare Polure Window Pediments for final painting?
Fill screw holes and miter seams with acrylic putty, sand smooth with 180-220 grit paper, and apply two coats of paint.
