Polyurethane Round Curved Arch for Windows and Doors

This decorative element, model reference P1456D230VI, is a curved pediment profile designed to revive classic architectural lines over doors and windows. Combining the traditional arch form with modern engineering, this product adds depth and volume to any surface. Its lightweight structure ensures easy installation while significantly enhancing the aesthetic value of buildings.

Manufactured from high-density rigid polyurethane (150-220 kg/m³), this curved arch features a surface hardness comparable to wood. With a profile width of 137 mm, a span of 1109 mm, and a height of 302 mm, it offers ideal proportions for medium to wide openings. Thanks to its closed-cell structure, its water absorption rate is below 1%, largely preventing swelling, rotting, or cracking under harsh weather conditions such as moisture, rain, and frost.

Visually, the product stands out with the play of light and shadow created by its stepped outer edges and smooth inner curve. The L-shaped rebate detail in the profile cross-section ensures a flush fit during installation, creating clean finish lines. The factory-applied primer facilitates excellent adhesion for the topcoat. While an additional primer coat is optional due to paint manufacturers' warranty terms, water-based or synthetic topcoats can be safely applied.

Highly versatile, this curved element is ideal as a window header on villa facades or as a grand door pediment in hotel lobbies and restaurant entryways. Indoors, it creates an elegant border in wide hallway transitions, decorative niches above fireplaces, or wall paneling behind headboards. Include the product weight and fixing loads when assessing the substrate and supporting structure.

Installation should be carried out on dry and even surfaces. For securing, Polure Polfix adhesive must be used, supported by mechanical screwing. Once screw heads and joints are filled and sanded, the painting process can begin. For exterior applications, a UV-resistant exterior paint is required to ensure long-lasting weather resistance.
