The polyurethane round arched trim is a structural decorative element designed to create soft, circular contours over door and window openings. This custom-designed model, SKU P85401D160VI, blends the aesthetic curves of traditional architecture with modern manufacturing technology. By breaking the monotony of straight lines in buildings, it adds depth and character to transition areas. With its durable structure, it offers a long-lasting decorative solution for both interior designs and exterior facade applications.
The product offers balanced proportions with a profile width of 50 mm, an arch length of 1244 mm, and a height of 314 mm. It is manufactured from high-density rigid polyurethane raw material (150-220 kg/m³). This density provides a wood-like hardness and durability while maintaining its lightweight structure. Thanks to its closed-cell formulation, its water absorption rate is below one percent, offering high resistance to moisture, rot, and insect infestation. With dimensional stability tested between -20 °C and +70 °C, it does not expand, shrink, or crack during seasonal transitions.
As seen in the visual, the front surface of the product features detailed curves resembling a stepped, classic crown molding profile. The yellow cross-section on the back displays the dense and robust inner structure of the polyurethane, while the smooth white front surface provides a finish ready for installation. Unlike plaster or wood alternatives, this resilient curved structure carries a reduced risk of breakage, minimizing installation errors and adding no extra static load to the building.
This versatile curved arch is highly preferred for framing round windows on villa facades, decorating the pediments of entrance doors, and integrating with floor moldings. Indoors, it creates an architectural focal point in hallway transitions, wide living room arches, the tops of niches, and prestigious areas like hotel lobbies. For exterior applications, it must be painted with a UV-resistant exterior paint to prevent yellowing caused by UV rays.
During installation, applying the product to a clean and dry surface is essential. Only Polure Polfix polyurethane adhesive should be used for bonding; silicone-based adhesives must be avoided. For a secure application, mechanical fastening with screws is mandatory. The product is shipped factory-primed. Although this primer prepares the surface for painting, applying an additional primer before the final coat is entirely at the user's discretion, as paint manufacturers often require their own primers for warranty purposes. Polure does not accept liability for paint application and subsequent performance.
- <p>Polyurethane curved arch models have a wide range of applications in both interior and exterior decoration
- On exteriors, they are utilized as trim elements over arched windows and doors of villas, mansions, hotels, and prestigious public buildings constructed in classic and neoclassical styles
- They are ideal for highlighting circular portals at building entrances and adding movement to the facade
- Additionally, they can be integrated with floor moldings to create an aesthetic pediment effect above windows.</p><p>Indoors, they are frequently preferred in doorless transition hallways, partition arches between living and dining rooms, the upper curves of wall niches, and decorative panels behind headboards
- Especially in commercial spaces like restaurants and cafes, they enhance the depth of the venue by creating soft transitions between sections
- They also serve as an excellent alternative for customizing meeting room entrances in office projects or creating curved frames in wall designs behind reception desks in lobby areas
- Fully adaptable to exterior conditions when painted with correct techniques, this product easily integrates into architectural projects of various styles.</p>
- For polyurethane arch installation, first ensure that the application surface is clean, dry, and smooth
- The ends of the curved arch element are precisely cut at angles suitable for the installation area
- Only Polure Polfix polyurethane adhesive must be used for bonding; silicone or similar adhesives should not be used
- The adhesive is applied to the back of the product, which is then pressed onto the surface and mechanically secured with screws to ensure full structural strength
- After covering screw heads and joints with polyurethane filler, the surface is smoothed using 180-220 grit sandpaper
- Following an optional additional primer over the factory-applied primer, the process is completed with two coats of water-based or synthetic paint
- Maintenance of polyurethane products is extremely practical and effortless
- Interior arch surfaces can be regularly dusted by wiping with a slightly damp, soft cloth
- Abrasive chemicals, acidic solvents, thinners, or wire sponges must never be used during cleaning
- For exterior applications, the condition of the paint on the product should be checked periodically
- Repainting with exterior paint every few years protects the material's lifespan and aesthetics against the degrading effects of UV rays
- Heavily dusted exterior surfaces can be easily cleaned by washing with low-pressure water
Is it safe to use polyurethane curved arches on exteriors?
Yes, it is highly safe. Since our product is manufactured from rigid polyurethane with a closed-cell structure, its water absorption rate is below one percent and it is weather-resistant. However, if used on exteriors, it must be painted with a UV-resistant exterior paint to prevent yellowing caused by solar UV rays.
Which adhesive should I use during installation, and is mechanical fastening required?
Only Polure Polfix polyurethane adhesive must be used during installation. Silicone-based adhesives may cause bonding failure in the long run. Additionally, to ensure the curved structure fits perfectly onto the surface and for safety reasons, it is mandatory to mechanically secure the product to the wall with screws.
Does the product come painted from the factory, and can I paint it directly?
Our product is shipped from the factory with a special white primer applied. This primer prepares the surface for painting. However, since paint manufacturers do not guarantee paint jobs done without their own primers, applying an additional primer before the topcoat is entirely at the customer's discretion. Polure does not accept responsibility for paint performance.
What are the advantages of polyurethane curved arches compared to plaster or wood alternatives?
