Polyurethane Curved Door and Window Pediment Crown Profile

The P1470A is a premium architectural crown designed to elevate door and window frames with a stately, classical arch motif. Featuring a curved central dome that transitions smoothly into sleek horizontal wings, this decorative element adds structural depth and classical symmetry to any building facade or grand interior portal. It acts as an elegant architectural statement, transforming standard openings into high-end design features.

Manufactured from high-density rigid polyurethane (150-200 kg/m³), this pediment offers the structural integrity and crisp detailing of traditional wood without the susceptibility to environmental decay. Measuring 2400 mm in width, 422 mm in height, and with a projection depth of 108 mm, it is engineered for substantial visual impact. Its closed-cell structure ensures a water absorption rate of less than 1%, rendering it completely immune to rotting, swelling, warping, or insect infestation under extreme weather conditions.

The visual profile of the P1470A is defined by its clean, smooth, multi-layered step moldings that trace the gentle sweep of the central arch. This lack of heavy, ornate floral carvings makes it highly versatile, successfully bridging the gap between classical Neoclassical architecture and clean-lined modern transitions. The factory-applied base primer provides a uniform, smooth surface that optimizes paint adhesion for a flawless final finish.

This decorative architectural pediment is primarily utilized to crown exterior window frames, main entrance doors, and porticos on high-end residential villas, boutique hotels, and historical restorations. Indoors, it serves as a dramatic overdoor decorative header in spacious hallways, high-ceilinged living rooms, or grand ballroom entrances, creating an immediate sense of architectural purpose and luxury.

Compared to heavy cast concrete, plaster, or high-maintenance timber, this lightweight polymer alternative significantly reduces structural load on the building envelope and simplifies installation. The process involves securing the pediment with a polyurethane (PU) mounting adhesive combined with mechanical screws for permanent stability. The joints and screw heads are then easily filled, sanded, and coated with a high-quality topcoat.

The P1470A offers an enduring, low-maintenance decorative solution that retains its crisp profiles over decades of exposure. While the factory-applied primer prepares the surface, applying an additional primer compatible with your chosen paint system is optional but recommended to meet specific paint manufacturer warranties, as Polure does not accept liability for third-party paint performance.
