Designed to soften transition areas and add depth to architectural spaces, this polyurethane round arch model offers an elegant aesthetic with its classic semi-circular form. This exclusive design, coded P14D25D100VI, enhances structural integrity in both interior hallways and doorways, as well as exterior window pediments. Developed as a lightweight alternative to heavy and fragile plaster, this durable architectural element reduces structural load while ensuring long-lasting performance.
The product is manufactured from high-density rigid polyurethane (150-220 kg/m³). With a depth of 60 mm, a span (width) of 1320 mm, and a height of 660 mm, it forms a perfectly symmetrical semi-circular profile. Thanks to its closed-cell structure, it offers superior resistance to moisture and water; with a water absorption rate below 1%, it will not swell, shrink, or warp. Its outstanding dimensional stability has been tested within -20 °C / +70 °C, making it highly reliable even in harsh outdoor environments.
Visually, it features a sleek yet impactful profile created by the harmonious blend of stepped and circular contours. Its smooth, flat surface seamlessly complements a wide range of styles, from modern minimalist designs to classic neoclassical restorations. These stepped curves create elegant shadow play, adding three-dimensional depth to any surface and transforming ordinary wall transitions into striking architectural focal points.
Offering versatile application possibilities, this curved arch is highly favored for window pediments on villa facades, main building entrances, and arched passageways. Indoors, it serves as an aesthetic frame for grand living room entrances, hotel lobbies, restaurant hallways, or decorative wall niches. Assess water and moisture exposure using the product technical data, surface finish and installation details.
Installation is significantly easier compared to plaster or wood alternatives. It is applied to a clean, dry surface using Polure Polfix adhesive and secured with screws for mechanical stability. The factory-applied primer provides an excellent base for painting. However, due to paint manufacturers' warranty policies regarding their own primers, applying an additional primer coat before the final paint is optional. For outdoor applications, a UV-resistant exterior paint must be used to protect the polyurethane structure from sun damage.
- The polyurethane round curved arch is highly versatile, making it ideal for both interior design and exterior architecture
- On exterior facades, particularly in classic and modern villa projects, it serves as an elegant frame for window pediments
- It also adds an inviting architectural touch above main entrances and hotel portals
- Indoors, it is perfect for creating arched transitions in wide, doorless hallways or between living and dining areas, softening the junction between walls and ceilings
- Additionally, it can be used as a decorative border for wall niches or circular headboard panels
- Frequently preferred in restaurants, cafes, and retail window displays to create a sense of depth, this paintable product easily adapts to any interior color scheme
- Before installation, ensure the application surface is completely clean, dry, and free of dust or grease
- Align the curved arch precisely with the installation area
- Apply Polure Polfix adhesive to the back of the product and its joints, then press it firmly onto the surface
- For a secure and permanent bond, mechanical fastening with screws is mandatory
- Fill any gaps at the joints and screw heads with a high-quality acrylic filler, and once dry, sand smooth using 180-220 grit sandpaper
- The factory-applied primer provides a paint-ready surface; however, applying an additional primer coat is optional to guarantee optimal paint adhesion
- Complete the installation by applying at least two coats of paint—water-based or synthetic paint for interiors, and strictly UV-resistant paint for exterior applications
- Maintaining polyurethane arches is exceptionally easy
- Thanks to their closed-cell structure, they are moisture-resistant, allowing for effortless cleaning with a damp cloth
- Avoid using abrasive chemicals, acidic solvents, or stiff brushes
- For exterior installations, washing with high-pressure water to remove dust and environmental buildup is perfectly safe
- To preserve the paint's lifespan and UV protection outdoors, we recommend inspecting the painted surface annually and performing local touch-ups as needed
Can the polyurethane round curved arch be used on exterior facades?
Yes, because the product is made of high-density polyurethane with a closed-cell structure, it is highly resistant to water, moisture, and harsh weather conditions, making it perfectly safe for exterior use. However, to protect it from the yellowing effects of UV rays, it must be painted with a UV-resistant exterior paint after installation.
Which adhesive should I use to install the product?
For a strong and long-lasting bond, you should use Polure Polfix adhesive, which is specially formulated for polyurethane products. Silicone-based adhesives should be avoided as they do not provide sufficient strength. Additionally, relying solely on adhesive is not enough; mechanical fastening with screws is mandatory.
Does the product come pre-painted, and can I paint it directly?
The product is shipped with a factory-applied white primer, making the surface ready for painting. While it can be painted directly, paint manufacturers often do not warranty applications done without their own primers. Therefore, applying an additional primer coat is entirely optional and up to the customer.
What are the advantages of polyurethane arches compared to plaster or wood arches?
Include the product weight and fixing loads when assessing the substrate and supporting structure. Unlike wood alternatives, they are resistant to moisture, water, and pests, helping reduce rotting, warping, or deformation over time. They are also much easier to fill, sand, and install quickly.
Will the dimensions of the P14D25D100VI curved arch fit any window?
This model features a symmetrical semi-circular shape with a width of 1320 mm (132 cm) and a height of 660 mm (66 cm). It is generally ideal for standard-sized windows and doorways. The window or door opening in your project must align precisely with these dimensions or modular additions, as the product cannot be stretched or resized.
