Polyurethane Round Curved Arch Door and Window Header Decor

The P1472D170VI model polyurethane round curved arch is a decorative architectural element designed for both interior hallway transitions and exterior door and window headers. By bridging wide openings with an elegant circular curve, this structural piece enhances the depth perception of any space. Blending traditional arch forms with modern manufacturing technology, it elevates your structures from the ordinary, adding a distinctive and powerful architectural character.

With dimensions of 193 mm in width, 2310 mm in span (length), and 1155 mm in height, this product is ideal for large-scale and prestigious projects. It is manufactured from high-density (150-220 kg/m³) rigid polyurethane. This density provides a surface hardness comparable to wood while keeping the product lightweight. Thanks to its closed-cell structure, its water absorption rate is below 1%, ensuring it will resist swelling, rot and deterioration in humid interiors or exterior applications. It maintains its shape across a temperature range of -20 °C / +70 °C, offering exceptional dimensional stability.

The smooth, stepped inner profile design highlights the elegance of the circular curve. Its clean yet defined lines ensure a harmonious transition in neoclassical and modern-classic projects. The flawless surface quality achieved through advanced molding technology perfectly delivers symmetrical curve details that are difficult to craft by hand. Delivered pre-primed in factory white, the surface provides an ideal base ready for the final coat of paint.

This curved arch element is highly favored for wide living room transitions, hallways, hotel lobbies, and restaurant entrances. On exteriors, it is particularly used as decorative door headers for villas or as arch window surrounds (trims). For exterior applications, using UV-resistant paint is mandatory to protect the product against sunlight exposure.

Compared to heavy plaster or hard-to-work-with wood alternatives, its lightweight nature makes it easy to transport and install. For installation, Polure Polfix adhesive should be applied to the cleaned surface, followed by mechanical fastening with screws. Although the factory primer prepares the surface for painting, an additional coat of primer prior to the topcoat can be optionally applied to meet specific paint manufacturers' warranty terms. Once screw holes and joints are filled and sanded, the arch can be painted with water-based or synthetic paints.
