Polyurethane Round Curved Arch with Keystone

The P1456D95VID is a decorative curved arch element designed to add elegant depth to doors, windows, and corridor transitions. Combining the timeless arch form of classical architecture with a prominent keystone detail, it seamlessly integrates into both facade and interior designs. By eliminating the laborious processes of traditional stone and plaster craftsmanship, this lightweight product offers easy installation and imparts a historic charm while putting only a limited load on the structure.

Measuring 170 mm in depth, 1350 mm in width, and 771 mm in height, this piece offers ideal proportions for wide-span doors or windows. Manufactured from high-density (150-220 kg/m³) rigid polyurethane, it provides the durability of wood while offering resistance to moisture, rot, and insect infestation. Thanks to its closed-cell structure, its water absorption rate is below 1%, making it exceptionally long-lasting for both interior and exterior applications.

The smooth curved lines and stepped profile transitions featured in its design enhance depth through subtle light-and-shadow play. The trapezoidal keystone motif at the apex of the arch provides a symmetrical focal point, complementing classic neoclassical styles. Ideal for adding movement to flat wall surfaces and softening sharp angles, this clean, geometric form is suitable for a wide range of projects, from traditional restorations to modern villa facades.

This decorative element is highly favored for exterior door pediments in villas and mansions, arched window surrounds, and porch transitions. Indoors, it is used to divide spacious living room entrances, enrich hallway passages, or create arched niches in prestigious areas like hotel lobbies. Thanks to its lightweight nature, it can also be safely installed on suspended ceilings or lightweight partition wall systems.

Developed as an alternative to fragile plaster arches and wood that warps or cracks over time, this polyurethane foam material can be easily cut and drilled. Delivered with a factory-applied white primer, the surface ensures excellent paint adhesion. Due to individual paint manufacturer warranties on their primers, applying an additional primer coat before the final paint is optional. When used outdoors, it must be painted with a UV-resistant exterior paint to protect it from sunlight degradation.
