Decorative Arch Pediment
Polure Decorative Arch Pediment provides a grand crowning statement for interior doorways, window surrounds, and entrance portals. Molded from rigid high-density polyurethane (150-220 kg/m³), this arched pediment delivers classical architectural prominence while avoiding heavy structural strain. Its closed-cell composition holds moisture absorption strictly below 1%, protecting against rot, swelling, or mold in both indoor and outdoor applications. Rated B2 fire retardant and thermally stable from -100 °C / +80 °C. Installation requires applying a continuous line of polyurethane assembly adhesive across all contact boundaries and joinery seams, reinforced with countersunk mechanical screws; silicone adhesives are strictly forbidden. Screw holes and seam joints must be filled with acrylic filler and sanded smooth using 180-220 grit paper. Factory-prepped with white acrylic primer, it accepts standard water-based interior paints or UV-resistant exterior paints.
