The decorative architectural element with reference code P1476D276VI is a specially designed curved arch profile crafted to aesthetically crown door and window openings. Blending the vaulted and arched transition forms of traditional architecture with modern manufacturing technology, this product adds a sense of depth to both interior and exterior designs. While imparting a classic character to structures, its lightweight composition ensures effortless installation.
The product features dimensions of 75 mm in thickness, 1254 mm in width, and 310 mm in height (arch rise). It is manufactured using rigid polyurethane raw material with a density of 150-220 kg/m³ (production target ~160 kg/m³). This high density provides a hardness and impact resistance comparable to wood, while keeping the material lightweight enough for easy handling during installation. Thanks to its closed-cell structure, its water absorption rate is below 1%, completely eliminating issues such as moisture, rot, or insect infestation. It perfectly retains its shape under temperature fluctuations ranging from -100 °C / +80 °C.
Visually, the product boasts a smooth surface texture characterized by interlocking stepped lines. This curved profile captures the interplay of light and shadow, bringing dynamism to any facade or wall. While the light yellow tone on the back reveals the high-density core of the material, the white factory primer on the front surface provides an ideal base for painting. Unlike plaster or concrete alternatives, it does not crack and preserves its sharp detail definition for years.
Offering a wide range of applications, this arch element is highly favored as window pediment crowning, particularly on villa and hotel facades. Indoors, it creates an elegant boundary line in wide living room transitions, hallway corridors, or niche decorations. When properly painted, it adapts flawlessly to harsh outdoor conditions. It also serves as an ideal alternative for replicating historical textures in restoration projects.
During installation, ensuring a clean and dry surface is crucial. Polure Polfix adhesive should be applied to the back of the product, followed by mechanical fastening using anchors or screws. Once screw holes and joints are filled with putty and sanded smooth with 180-220 grit sandpaper, an additional coat of primer can be applied if desired. To prevent yellowing in outdoor applications, it is highly recommended to apply two coats of UV-resistant exterior paint.
- Thanks to its versatile design, this curved arch profile offers a wide range of applications for both interior and exterior spaces
- On exterior facades, it is used to highlight main decorative lines in window pediment crownings, entrance portals, and decorative arched transitions at building entrances
- Especially in villa facade designs, placing it above windows creates a classic and prestigious look
- Indoors, it is preferred as an aesthetic detail in doorless transition arches between living rooms and hallways, high-ceilinged hotel lobbies, and niche designs in commercial spaces like restaurants and cafes
- Additionally, it can be used as a unique visual element in decorative framing over fireplaces, curved wall panel combinations behind headboards, or conservatory transitions
- Thanks to its paintable structure, it easily adapts to the color scheme of any application area, enhancing the architectural integrity of the space
- The application surface must be completely free of dust, moisture, and grease
- Polure Polfix adhesive is applied in strips to the back of the profile
- Once the product is positioned on the wall, mechanical fastening with screws or nails is mandatory to ensure structural strength
- Screw heads should be countersunk, and screw holes as well as joints must be filled with flexible exterior putty
- After the putty dries, the surface is sanded smooth using 180-220 grit sandpaper
- Although the factory primer is ready for painting, applying an additional coat of primer for paint manufacturer warranty compliance is optional and at the customer's discretion
- In the final step, the installation is completed by applying at least two coats of UV-resistant paint for outdoor use, or water-based/synthetic paint for indoor use
- The polyurethane curved arch is extremely easy to maintain, as its closed-cell structure makes it completely resistant to water and moisture
- Dust and dirt on the surface can be periodically wiped away with a damp cloth
- Abrasive chemicals, thinners, or acid-based cleaners should not be used during cleaning
- For exterior applications, it is recommended to inspect the painted surface every one or two years depending on exposure to sunlight and weather conditions, and touch it up if necessary
- It is also suitable for pressure washing
Is the polyurethane curved arch resistant to outdoor weather conditions?
Yes, the product is manufactured from rigid polyurethane with a closed-cell structure. Since its water absorption rate is below 1%, it is unaffected by rain, snow, and moisture, preventing rot or swelling. With a temperature resistance ranging from -100 °C / +80 °C, it can be safely used on exterior facades. However, since it will be exposed to sunlight outdoors, it must be painted with a UV-resistant exterior paint after installation.
What are its advantages compared to plaster or wooden arches?
Plaster arches are quite heavy and fragile, and they can crumble over time by absorbing moisture. Wooden arches, on the other hand, are sensitive to humidity, carrying risks of rotting and insect infestation. In contrast, the polyurethane arch is as hard as wood yet extremely lightweight, shatterproof, and 100% resistant to moisture and water. It features highly sharp detail definition and offers a much faster, more practical installation.
Which adhesive should I use during installation?
To ensure excellent adhesion and sealing during installation, only Polure Polfix polyurethane adhesive should be used. Silicone or standard adhesives do not provide a long-lasting bond for this material. Additionally, mechanical fastening with screws is mandatory in conjunction with the adhesive.
Can the product be used directly without painting?
The product comes with a protective white factory primer. However, to protect the material from external elements and to seamlessly blend the joints and screw holes filled with putty, painting after installation is essential. UV-resistant paints should be preferred for outdoor use, while water-based or synthetic paints are suitable for indoor applications.
Can the flexibility or arch degree of the product be modified during installation?
No, since this product is manufactured from high-density rigid polyurethane, it has a fixed form and cannot be flexed or bent. The arch shape with dimensions of 75x1254x310 mm is completely rigid. Before ordering, you should ensure that the arch degree of your door or window opening matches the product dimensions.
