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 not swell, rot, or deteriorate in humid interiors or exterior applications. It maintains its shape across a temperature range of -100 °C / +80 °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.
- The P1472D170VI model polyurethane round curved arch offers versatile application possibilities in both interior architecture and exterior designs thanks to its generous dimensions
- Indoors, it is ideal for creating elegant arched transitions in doorless entryways and at the ceiling junctions of wide corridors
- It serves as a decorative divider above partition walls, especially in hotel lobbies, restaurants, wedding venues, and spacious classically designed living rooms
- On exteriors, it is positioned as a circular pediment above the entrance doors of villas, mansions, or historical-style buildings, as well as over arched window frames
- The product's fully water- and moisture-resistant structure also allows for safe use on arched garden gates or veranda entrances
- With the right painting and installation techniques, it becomes a stunning focal point in both modern and classical facade designs
- Installing the polyurethane round curved arch is highly practical
- First, the application surface must be dry, clean, and free of dust
- To secure the arch, apply Polure Polfix polyurethane adhesive to its back surface
- Due to the product's large dimensions, mechanical fastening with screws is mandatory to prevent slipping while the adhesive cures
- Screws should be driven so that their heads are slightly countersunk into the surface
- Once fully dry, fill the screw holes and joints with a high-quality exterior-grade putty
- After the putty dries, sand the surface smooth using 180-220 grit sandpaper
- Although the factory primer prepares the surface for painting, applying an optional extra coat of primer is recommended for paint longevity
- Finally, complete the installation by applying at least two coats of water-based or synthetic paint
- The closed-cell structure of the polyurethane material makes maintenance exceptionally easy
- For interior use, dusty arch surfaces can be easily cleaned with a damp cloth
- Abrasive cleaners containing harsh chemicals and stiff brushes should be avoided
- For exterior applications, the product can be washed with pressurized water, and thanks to its dirt-repellent nature, it stays clean for a long time
- Since unpainted polyurethane can be affected by UV rays, the quality of the paint used outdoors is crucial
- Checking the painted surface once a year and applying local paint touch-ups when necessary will keep the product looking as fresh as day one
Can the polyurethane round curved arch be used on exteriors?
Yes, thanks to its closed-cell structure, the product is fully resistant to water and moisture, making it perfectly safe for exterior use. However, when installed outdoors, a UV-resistant exterior paint must be applied to protect it from the yellowing effects of sunlight.
Which adhesive should be used during installation?
For a strong bond and long-lasting durability, only Polure Polfix polyurethane adhesive should be used for arch installation. Silicone-based adhesives do not provide sufficient strength on polyurethane. Additionally, due to the size of the product, mechanical fastening with screws is mandatory.
Can the product be used directly without being painted?
No, the product comes pre-primed in factory white, but this is not a final topcoat. To protect the polyurethane material from UV rays and achieve an aesthetic finish, it must be painted with at least two coats of water-based or synthetic paint before use.
What are its advantages compared to plaster or wood arches?
It is significantly lighter than plaster arches and carries no risk of cracking or breaking upon impact. Compared to wood, it is highly resistant to moisture, water, rot, and insect infestation. Thanks to its high dimensional stability, it will not crack, shrink, or expand over time, making installation much faster and cleaner.
Is it mandatory to apply an extra coat of primer before installation?
The product comes with a special factory-applied primer and is ready for direct painting. However, paint manufacturers may not guarantee their paint's performance if applied without their own recommended primers. Therefore, applying an additional primer is optional and entirely up to the installer.
