The P14D20D80VI round arch is an exclusive decorative element that blends the aesthetic contours of traditional stonework with the lightweight advantages of modern polyurethane technology. Designed to create soft, circular transitions over doorways, corridor passages, and window frames, it adds architectural depth to any space. Its smooth surface finish ensures a seamless integration into both classic and neoclassical interiors.
With dimensions of 49 mm in depth, 1054 mm in width, and 527 mm in height, this product offers ideal proportions for standard openings. Boasting a high-density rigid structure of 150-220 kg/m³, it delivers a durability comparable to solid wood. Its closed-cell structure offers low water absorption (below 1%), helping reduce the risk of rotting, warping, or cracking over time.
As shown in the image, the interlocking, stepped circular profile lines play with light and shadow to create a striking sense of depth on the wall. Its minimalist yet defined design lends an elegant, understated sophistication to any surface without overpowering the space. These multi-layered curved lines elevate flat walls, transforming them into architectural focal points.
Highly versatile, this arch is widely favored for interior entryways, fireplace niches, or as decorative framing for mirrors. On exteriors, it serves as an elegant window pediment or header, giving residential, hotel, or villa projects a distinctive, high-end facade identity.
Extremely lightweight compared to plaster alternatives, it ensures effortless installation while adding only limited weight to the building. During application, Polure Polfix adhesive should be applied to the back before securing it with screws for mechanical support. Once screw holes are filled and sanded, the surface is ready for painting.
The product comes factory-primed in white. While this primer prepares the surface, paint manufacturers often do not guarantee finishes applied over third-party primers; therefore, applying an additional primer is optional and at the customer's discretion. For exterior applications, using a UV-resistant paint is mandatory to protect against sun damage.

Is it resistant to outdoor weather conditions?
Yes, with a water absorption rate of less than 1%, the P14D20D80VI arch model is resistant to rain, snow, and moisture. However, to protect it from the effects of solar UV rays outdoors, it must be painted with a UV-resistant exterior paint after installation. Unpainted polyurethane products may yellow over time.
Can the product be used directly without painting?
The product is delivered factory-primed in white. However, it must be painted to achieve its final appearance and to protect it from external elements. Although the factory primer prepares the surface for painting, paint manufacturers do not guarantee applications done without their own primers, so applying an additional primer is entirely at the customer's discretion.
Which adhesive should I use for installation?
For a secure and long-lasting installation, only Polure Polfix polyurethane adhesive should be used. Silicone or similar flexible adhesives should be avoided as they may lose grip over time. Additionally, mechanical fastening with screws is mandatory alongside the adhesive.
What advantages does it have over plaster arches?
Compared to plaster alternatives, polyurethane arches are extremely lightweight and do not add extra load to the building. There is a reduced risk of cracking or breaking during transport and installation. It will not crumble over time due to moisture, is impact-resistant, and preserves its smooth surface details for years.
Do its dimensions fit every door or window?
The P14D20D80VI model features a width of 1054 mm and a height of 527 mm. These dimensions are ideal for standard single-leaf doorways or medium-width windows. For wider openings, flat casing profiles can be added modularly to the sides according to your architectural project.
