Polyurethane Round Arch and Door Top Curve Models

The P1456D95VI polyurethane round arch is an aesthetic architectural element that blends classic design with modern engineering for both interior and exterior transitions. Commonly used over doorways, window arches, and wide corridor openings, this circular form adds depth and a distinctive character to any space. Transforming the overall appearance of a building, this decorative product offers a practical installation alternative, eliminating the challenges associated with heavy stone or cast materials.

The product features a profile width of 137 mm, an outer diameter of 1350 mm, and a curve height (radius) of 675 mm. Manufactured from high-density rigid polyurethane (PU) at 150-220 kg/m³, it offers a surface hardness comparable to wood while remaining remarkably lightweight. Thanks to its closed-cell structure, the water-resistant formula prevents swelling, rotting, or cracking upon outdoor exposure. Furthermore, its dimensional stability has been tested between -20 °C and +70 °C, and it maintains its dimensional stability for years.

The visual design features elegant, stepped lines running seamlessly along its smooth surface. This fine-lined profile, continuing uninterrupted across the circular curve, creates an appealing depth through the play of light and shadow. With its simple yet sophisticated design, it effortlessly complements both classic traditional architecture and modern neoclassical facade designs.

Compared to traditional materials like plaster and wood, polyurethane arch models are highly impact-resistant and help deter pests. Include the product weight and fixing loads when assessing the substrate and supporting structure. While the factory-applied primer prepares the surface for the final coat, applying an additional primer remains optional based on paint manufacturer warranty guidelines.

Installation is straightforward. After applying Polure Polfix adhesive to the cleaned surface, the arch should be mechanically secured to the wall using screws. Avoid silicone-based adhesives during installation. Once joints and screw holes are filled with flexible filler and sanded, the process is completed by painting with water-based paints for interiors or UV-resistant paints for exteriors. Ultimately, polyurethane arches deliver long-lasting, maintenance-free decorative results.
