The architectural component coded P14D40D260VI is a specialized profile designed to create elegant circular transitions over wide openings and doorways. Accentuating the aesthetic power of curved lines on both interior and exterior walls, this piece adds depth and a classic character to any space. Thanks to its smooth, curved structure, it serves as a softening transition element even in modern buildings with sharp lines.
Manufactured from high-density rigid polyurethane, this product offers a surface hardness close to wood with a density of 150-220 kg/m³. With a profile thickness of 90 mm, an outer arc length of 3110 mm, and a vertical height of 1555 mm, it features ideal proportions for large arched windows and wide transition corridors. Thanks to the closed-cell structure of the material, its water absorption rate is below one percent, largely preventing swelling, rotting, or cracking when used in humid climates or on exterior facades.
The visual design reveals a stepped and smooth profile structure. Symmetrical curved lines narrowing from the outer edge inward bring dynamism to the facade through the play of light and shadow. Delivered factory-primed in white, the smooth surface provides an excellent base for the topcoat paint. Combining the dignified presence of classical architecture with modern manufacturing technology, these minimalist lines easily adapt to various interior design styles.
With a wide range of applications, this curved profile is highly favored above the entrance doors of luxury villas, in arched passageways of hotel lobbies, and as decorative partitions in restaurants. Indoors, it is perfect for crowning wall transitions between living rooms and hallways or framing the tops of large windows. On exteriors, it integrates seamlessly with window jambs to give the building's facade a prestigious look.
Being extremely lightweight and shatterproof compared to plaster alternatives, it offers great convenience during installation. This durable profile, which does not suffer from insect infestation or warping over time like wood, is easily secured to surfaces using Polure Polfix adhesive and mechanical screwing methods. Although the factory primer prepares the surface for painting, using an additional primer recommended by your paint manufacturer is advised for a long-lasting finish. Once the topcoat is applied, it retains its form for years without requiring maintenance.
- This round curved profile features a wide range of applications in both interior and exterior designs
- On exteriors, it is integrated with jamb systems above arched windows, entrance door frames, and porch transitions in prestigious projects like villas, detached houses, and hotels
- When used outdoors, it must be painted with a UV-resistant exterior paint to protect the material from sun damage
- Indoors, it is preferred for wide living room transitions, non-load-bearing decorative arch designs dividing corridors, creating niches behind headboards, or crafting stylish partitions in commercial spaces like restaurants and cafes
- Thanks to its lightweight structure, it can be safely installed on delicate surfaces such as suspended ceilings or partition walls without adding extra static load
- The installation surface must be dry, clean, and free of dust
- Align the profile on the wall according to its circular shape
- After making precise cuts for the joints, only Polure Polfix adhesive should be used for bonding; silicone-based adhesives must be strictly avoided
- In addition to the adhesive, mechanical anchoring with screws and dowels is mandatory due to the product's large dimensions
- Cover screw heads and joint lines with a high-quality exterior filler
- Once the filler dries, smooth the surface using 180-220 grit sandpaper
- Although the surface comes factory-primed, applying an optional coat of primer in accordance with the paint manufacturer's warranty terms is recommended
- Finally, complete the process by applying at least two coats of water-based or synthetic paint
- Maintenance of this arch profile made of rigid polyurethane is highly practical
- Thanks to its closed-cell structure, it is moisture-resistant, allowing easy cleaning with a damp cloth or by washing with water
- Avoid using abrasive chemicals and stiff brushes during cleaning
- For exterior applications, check the paint condition every few years to mitigate the effects of sunlight and weather conditions, and repaint if necessary
- The product is impact-resistant; in case of minor scratches or damage, it can be locally repaired with filler, sanded, and repainted
Will it be affected by the sun when used on exterior facades?
In its raw state, the product may turn yellow when exposed to UV rays. Therefore, when used outdoors, it must be painted with a high-quality, UV-resistant exterior paint after installation. Once painted, it retains its form without being affected by sun, rain, or frost.
Which adhesive should I use for installation?
Only Polure Polfix polyurethane adhesive must be used during installation. Silicone or similar flexible adhesives do not provide full adhesion to the surface and may cause gaps over time. Additionally, mechanical fastening with screws is mandatory due to the dimensions of the product.
What are its advantages compared to plaster arches?
Plaster arches are very heavy and fragile; they can easily crack during installation or due to vibrations. In contrast, this product is extremely lightweight yet highly resistant to impacts. Its installation is much faster and cleaner, and it does not add any extra static load to the building.
Does the product come pre-painted, and can I paint it directly?
The product comes with a factory-applied white primer that ensures a smooth surface and helps the paint adhere. However, since paint brands do not guarantee coverage without their own primers, applying an additional coat of primer before painting is entirely at the customer's discretion.
Does it rot or get infested by insects over time like wood?
No, due to its chemical structure, rigid polyurethane is resistant to water, moisture, and pests. Unlike wood, it has low water absorption (below 1%) and is less likely to swell, warp, rot, or attract insects over time. Therefore, it can be safely used in both interior wet areas and exterior facades.
