Polyurethane Curved Arch Models and Designs

The P1460D786HO is a specialized architectural element designed to bring a graceful circular form to door and window openings. By softening straight-lined wall transitions, this curved structural piece adds depth and architectural character to building facades. Suitable for both interior designs and exterior facade projects, it seamlessly blends the timeless look of traditional stonework with modern, durable technology.

Manufactured from high-density rigid polyurethane (150-200 kg/m³), this product offers structural strength comparable to wood. Measuring 58.8 cm in width, 136 cm in height, and 48 cm in depth, it provides ideal proportions for large window and door headers with wide spans. Thanks to its closed-cell structure, its water absorption rate is below 1%, making it completely resistant to moisture, rain, and frost. It maintains its dimensional stability for years without shrinking or cracking, and withstands temperature fluctuations from -20°C to +80°C, making it exceptionally durable for exterior applications.

Visually, the product stands out with its smoothly curved surface featuring stepped transitions. The layered profile and circular form create a beautiful play of light and shadow, adding three-dimensional depth to any facade. These clean yet impactful geometric lines serve as a harmonious transition element across a wide architectural spectrum, from neoclassical to contemporary designs.

This architectural element is widely preferred for grand villa entrance portals, arched transitions in hotel lobbies, above large living room doors, and as exterior window pediments. Thanks to its generous proportions, it is also highly suitable for historically accurate restorations and prestigious commercial projects to aesthetically complete column-to-arch connections.

Compared to heavy plaster or concrete alternatives, its lightweight structure does not put extra load on the building's load-bearing columns, making installation incredibly practical. While the factory-applied primer ensures excellent paint adhesion, applying an additional primer is optional and left to the installer's preference. During installation, the surface must be cleaned, 45-degree miter cuts must be made, and only Polure Polfix adhesive should be used. For a secure installation, mechanical fastening with screws is mandatory. For outdoor applications, using UV-resistant paint is essential to ensure long-term durability.
