Polyurethane Round Curved Arch Model

As a distinguished piece in our polyurethane architectural elements collection, the P1456D854VI is a round curved arch profile designed to create soft transitions between spaces and along ceiling borders. Combining traditional circular arch details with modern manufacturing technology, this product offers seamless visual continuity in any application. It helps soften sharp vertical lines at doorways, niche frames, or wall-to-ceiling junctions, creating a more fluid and spacious atmosphere.

With technical specifications featuring a depth of 137 mm, a length of 1744 mm, and a height of 282 mm, this profile easily accommodates wide spans. Manufactured from high-density (150-200 kg/m³) rigid polyurethane, it offers a surface hardness comparable to wood while remaining exceptionally lightweight. Thanks to its closed-cell structure, its water absorption rate is under one percent, providing complete resistance to moisture, rot, and pests. Its high dimensional stability against temperature fluctuations ensures it retains its shape even in outdoor environments.

Visually, the profile stands out with its elegant concave curved structure. Its smooth, flawless surface reflects light and shadow naturally, adding depth to any room. This simple yet striking curve integrates effortlessly with classic, neoclassical, or modern interior styles. While the factory-applied primer prepares the surface for the topcoat, applying an additional primer layer is entirely at the user's discretion, in line with paint manufacturers' warranty conditions.

Offering versatile applications, this profile is highly favored for arched doorways in villa entrances, grand window pediments, and interior room transitions. In prestigious spaces like hotel lobbies, restaurants, and spacious lounges, it can also serve as a concealed lighting cove along ceiling borders. Unlike plaster alternatives, it does not crack or crumble, and unlike wood, it does not swell in damp environments, making it a highly practical choice for commercial projects.

During installation, ensuring a dry and dust-free surface is critical. Only Polure Polfix adhesive should be used for joints and bonding; silicone-based products must be strictly avoided. Mechanical fastening with screws is required; screw heads and joints should be filled with exterior-grade filler and sanded smooth using 180-220 grit sandpaper. For outdoor applications, using UV-resistant paints will maximize the product's lifespan against sunlight exposure.
