Designed to create smooth transitions and elegant circular forms in architectural designs, the P14D40D200VI is a premium structural element featuring a semi-circular curved profile. With a width of 90 mm, a circular arc length of 2510 mm, and a height (radius) of 1255 mm, this profile provides seamless aesthetic integrity over doors, window arches, and wide corridor transitions. It brings the timeless look of classic arches to modern spaces without adding extra static load to the structure, eliminating the laborious processes of traditional stone or plaster craftsmanship.
Manufactured from high-density rigid polymer (150-220 kg/m³), this profile offers a hardness close to wood while showing exceptional resistance to impacts. Thanks to its closed-cell structure, its water absorption rate is below 1%, preventing swelling, rotting, or cracking in humid environments, bathroom transitions, or exterior applications. With outstanding dimensional stability tested between -20 °C and +70 °C, it retains its form for many years in both interior and demanding exterior conditions.
Offering an aesthetically smooth and clean circular line, this profile blends perfectly with classic, neoclassical, and modern-classic designs. The crisp, continuous curve enhances the perception of depth, making ceilings appear higher in any applied space. Delivered factory-primed in white, the surface provides an ideal base for the topcoat. For exterior applications, coating with UV-resistant paint is highly recommended to protect against sunlight.
This versatile curved arch element is ideal for creating grand door portals in hotel lobbies, villa entrances, restaurant halls, and luxury residential projects. Extremely lightweight and shatterproof compared to plaster alternatives, it ensures easy installation on-site and minimizes transport damage. Unlike wood, it does not warp, bend, or attract pests, offering a long-term, maintenance-free investment.
- This round curved arch profile offers a wide range of architectural applications
- It is highly preferred in exterior designs as a header framing for arched windows
- It serves as an excellent alternative for creating grand portals at the main entrances of private villas, crowning decorative niches on garden walls, and highlighting veranda transitions
- Indoors, it creates a stunning focal point in wide transition areas between living rooms and hallways, above double doors, and in wall paneling designs behind hotel reception desks
- The product can be easily customized with water-based or synthetic paints to match the overall concept of the space (such as antique, rustic, or modern)
- The installation surface must be completely dry, clean, and free of dust, moisture, and grease
- The joint points of the profile should be precisely measured and cut
- Only Polure Polfix adhesive must be used for bonding; silicon-based adhesives should be avoided
- For secure mechanical fastening, screwing the profile to the wall with stainless screws is mandatory
- Screw heads and joints should be filled with a high-quality exterior filler, allowed to dry, and then smoothed with 180-220 grit sandpaper
- Although the factory-applied primer protects the surface, applying an additional primer coat is optional and depends on the user's preference to comply with the topcoat manufacturer's warranty terms
- Finally, complete the installation by applying two coats of water-based paint, or UV-resistant paint for exterior use
- Cleaning the product is highly practical
- For indoor applications, it can be dusted using a slightly damp, soft cloth or sponge
- For outdoor installations, dust and mud residues on the surface can be easily washed off with low-pressure water
- Abrasive acids, thinners, or solvents containing concentrated chemicals must never be used during cleaning
- For exterior applications, it is recommended to inspect the joints and paint condition once a year, depending on wind and structural vibrations, and perform local filler and paint touch-ups if necessary
Is it resistant to outdoor weather conditions and sunlight?
Yes, thanks to its high-density rigid PU structure, the product is weather-resistant to outdoor conditions such as rain, snow, and frost, with a water absorption rate below 1%. However, the unpainted raw material may yellow over time when exposed to UV rays. Therefore, for exterior installations, it must be coated with UV-resistant exterior paints to protect against sunlight.
Which adhesive should be used during installation, and is mechanical fastening required?
Polure Polfix adhesive, which provides high bonding strength, should be preferred for installation. In addition to bonding, due to the weight and curved form of the product, mechanical fastening using stainless screws is mandatory for safe and secure long-term use.
Does the product come pre-painted from the factory, and can it be painted directly?
The product is coated with a factory-applied white primer that smooths the surface and prepares it for painting. However, paint manufacturers do not guarantee applications done without their own priming systems. Therefore, applying an additional primer is entirely optional, and the final decision and paint warranty responsibility belong to the customer.
What are its advantages compared to plaster or wooden arches?
Unlike plaster, it is not fragile, is extremely lightweight, and does not crack during installation. Unlike wooden materials, it does not rot or warp due to moisture and is resistant to pests. It is both longer-lasting and significantly reduces installation time and labor costs.
Do the dimensions of the P14D40D200VI model fit every door and window?
This model features a profile width of 90 mm, an outer arc span of 2510 mm, and a height of 1255 mm. These dimensions form a semi-circular arch designed for standard double doors or wide window openings. We recommend verifying compatibility with your project dimensions using your architectural plans.
