Polyurethane Round Curved Arch Model

The P1456D307VIE polyurethane curved arch is a high-relief architectural ornament designed to crown the tops of windows and doorways. Blending the grandeur and rich detailing of classical architecture with modern manufacturing technology, this product adds depth and a distinctive character to any space. It offers a highly practical, durable, and lightweight alternative to the heavy stone or plasterwork of traditional structures, significantly reducing labor time in your projects.

The product features dimensions of 116 cm in width, 58 cm in height, and 28.8 cm in depth (wall thickness). These balanced proportions offer a perfect scale for standard door widths and medium-sized windows. Thanks to its high-density rigid polyurethane structure (150-220 kg/m³), it possesses the strength of wood but is far more impact-resistant. With its closed-cell structure that prevents water absorption (<1%), this arch retains its shape in temperatures ranging from -20 °C / +70 °C, without shrinking, expanding, or cracking.

The design details showcase a prominent embossed keystone motif at the exact center, surrounded by baroque-inspired acanthus leaf scrolls. The stepped profile of the curved main body brings a three-dimensional dynamism to the facade through the interplay of light and shadow. The angled cross-section on the back of the product ensures a flush fit against the mounting surface, helping to achieve a clean finish at the joints.

This versatile decorative element is widely preferred in residential projects, luxury villas, hotel lobbies, and historical building restorations. Indoors, it is ideal for corridor transitions, niche headers, and over-mantel wall decorations, while on exteriors, it serves as a window pediment crown or an ornamental topper for arched entryways. Thanks to its moisture-resistant properties, it can also be safely installed at the entrances of wet areas like bathrooms and spas.

Installation is carried out on dry and clean surfaces using Polure Polfix adhesive. For maximum strength and safety, mechanical fastening with screws or nails from the back of the product is mandatory. The factory-applied primer prepares the surface for painting; however, due to warranties offered by paint manufacturers on their own priming systems, applying an additional primer before the topcoat is entirely at the user's discretion. For exterior applications, a UV-resistant exterior paint must be used to protect the material from UV rays.
