The P1460D786HO is a specialized architectural element designed to bring a graceful circular form to door and window openings. By softening straight-lined wall transitions, this curved structural piece adds depth and architectural character to building facades. Suitable for both interior designs and exterior facade projects, it seamlessly blends the timeless look of traditional stonework with modern, durable technology.
Manufactured from high-density rigid polyurethane (150-220 kg/m³), this product offers structural strength comparable to wood. Measuring 58.8 cm in width, 136 cm in height, and 48 cm in depth, it provides ideal proportions for large window and door headers with wide spans. Thanks to its closed-cell structure, its water absorption rate is below 1%, making it completely resistant to moisture, rain, and frost. It maintains its dimensional stability for years without shrinking or cracking, and withstands temperature fluctuations from -100 °C / +80 °C, making it exceptionally durable for exterior applications.
Visually, the product stands out with its smoothly curved surface featuring stepped transitions. The layered profile and circular form create a beautiful play of light and shadow, adding three-dimensional depth to any facade. These clean yet impactful geometric lines serve as a harmonious transition element across a wide architectural spectrum, from neoclassical to contemporary designs.
This architectural element is widely preferred for grand villa entrance portals, arched transitions in hotel lobbies, above large living room doors, and as exterior window pediments. Thanks to its generous proportions, it is also highly suitable for historically accurate restorations and prestigious commercial projects to aesthetically complete column-to-arch connections.
Compared to heavy plaster or concrete alternatives, its lightweight structure does not put extra load on the building's load-bearing columns, making installation incredibly practical. While the factory-applied primer ensures excellent paint adhesion, applying an additional primer is optional and left to the installer's preference. During installation, the surface must be cleaned, 45-degree miter cuts must be made, and only Polure Polfix adhesive should be used. For a secure installation, mechanical fastening with screws is mandatory. For outdoor applications, using UV-resistant paint is essential to ensure long-term durability.
- This curved architectural element offers a wide range of applications for both interior and exterior spaces
- Indoors, it is used to add depth to grand living room transitions and door arch designs in prestigious venues like hotel lobbies and restaurants
- Outdoors, it serves as a non-load-bearing decorative accent for villa window trims, main entrance portals, and hallway or veranda archways
- Thanks to its wide and curved profile, it delivers outstanding results when framing circular windows or adding a classic arched look above standard flat windows
- The installation area must be completely free of dust and moisture
- Profile ends should be precisely cut at a 45-degree angle
- Only Polure Polfix polyurethane adhesive must be used for bonding; do not use silicone
- Due to the product's wide structure and weight, mechanical fastening with screws is mandatory
- Screw heads and joints should be filled with exterior-grade putty and smoothed using 180-220 grit sandpaper
- An optional additional primer can be applied over the factory-applied primer according to the paint manufacturer's recommendation, followed by at least two coats of paint
- For exterior applications, using UV-resistant paint is mandatory
- To clean the product, a damp cloth and water without abrasive chemicals are sufficient
- For outdoor installations, an annual surface inspection is recommended depending on the paint's condition
- In case of any impact or physical damage, the surface can be lightly sanded, repaired with putty, and spot-painted
Is it resistant to outdoor weather conditions?
Yes, manufactured from rigid polyurethane, this product has a water absorption rate of less than 1%. This ensures it remains unaffected by rain, moisture, and frost, without cracking or shrinking. To ensure long-lasting outdoor durability, it must be painted with a UV-resistant exterior paint after installation.
Which adhesive should be used for installation?
Only Polure Polfix polyurethane adhesive should be used during installation. Silicone-based adhesives do not provide long-term bonding. Additionally, mechanical fastening with screws is required for a secure and safe installation.
What are its advantages compared to plaster arches?
Plaster arches are heavy and fragile; they can degrade over time due to moisture. Include the product weight and fixing loads when assessing the substrate and supporting structure. It is highly impact-resistant, shatterproof, and completely unaffected by moisture.
Is the product ready to paint, or does it require a primer?
The product comes with a factory-applied primer and is ready for painting. However, since paint manufacturers do not guarantee applications done without their own primers, applying an additional primer is optional and depends on the customer's preference.
Can it be used for interior ceiling or wall transitions?
Yes, it can easily be used indoors to create curved arches for door transitions, above niches, or as living room dividers. Thanks to its lightweight structure, it easily adapts to drywall or plastered walls.
