Door Frame Pilaster Cap
Polure door frame pilaster caps provide an architectural crowning capital designed specifically to top vertical door casing pilasters and grand entryway architraves. Molded from high-density rigid polyurethane (150-220 kg/m³), these flat-backed capitals deliver wood-like physical durability and sharp detail while remaining lightweight for secure overhead wall mounting. Their closed-cell structural body retains water absorption strictly under 1%, ensuring they will not warp, swell, rot, or foster mold growth in humid entryways or exterior door surroundings. Rated B2 for fire safety and stable from -100 °C / +80 °C, each capital comes factory pre-primed with white acrylic technical primer. Installation requires dual fastening using polyurethane assembly adhesive and mechanical screws.
