Featuring the model code P14D30D160VI, this specialized architectural element is a durable round curved arch profile designed to create aesthetic transitions in both interior and exterior designs. Blending the vaulted and arched transition forms of traditional architecture with modern manufacturing technology, this product offers a deep visual appeal over doors and windows. Unlike heavy and fragile materials like plaster, its lightweight structure ensures easy installation while adding only limited weight to buildings.
Engineered with superior technical specifications, this arch profile features a width of 72 mm, a circular arc length of 1988 mm, and a curve height of 994 mm. Manufactured from high-density rigid polyurethane (150-220 kg/m³), the product offers a surface hardness similar to wood, providing high impact resistance. Thanks to its closed-cell structure, its water absorption rate is below 1%, preventing swelling or rotting in humid environments. It maintains its dimensional stability, with its shape preserved in a dimensional stability test between -20 °C and +70 °C.
Visually, it features a smooth and linear surface structure composed of interlocking circular steps. These clean and flowing lines add depth to the applied area through the interplay of light and shadow. With its elegant, understated design free from excessive ornamentation, it can be successfully utilized as a window and door framing element in both classical Ottoman and European architectural projects, as well as modern minimalist designs.
Offering a wide range of applications, this curved arch is highly preferred for over-window decorations on villa facades, building entrance pediments, and floor molding transitions. In interior design, it can be applied in wide living room transitions, hallway arches, wall niche claddings, or as a decorative dividing arch in prestigious commercial spaces such as hotel lobbies and restaurants. Thanks to its moisture-resistant structure, it can be used safely for many years without deformation in high-humidity areas like bathroom entrances, indoor pools, or spa centers.
During installation, Polure Polfix adhesive should be applied to a clean and dry surface, and mechanical fastening with screws must be completed. The factory-applied primer prepares the surface for painting. Since paint manufacturers do not guarantee surfaces outside of their own primer systems, applying an additional primer post-installation is optional and at the customer's discretion. Polure does not guarantee paint applications. If used outdoors, it must be painted with two coats of UV-resistant exterior paint to protect the material from sunlight damage.
- Thanks to its versatile design, this round curved arch has a wide range of applications in both interior and exterior projects
- In exterior designs, it provides visual harmony, especially for over-window trim decorations in detached houses and classical villa projects, crowning arched building entrance doors, and garden wall decorations
- Indoors, it is frequently preferred in wide transition corridors between the living room and dining room, decorative niche designs above fireplaces, bedroom headboard wall panel applications, and circular lines complementing classical ceiling crown molding transitions
- It can be used as an aesthetic dividing element in prestigious commercial spaces such as hotel lobbies, restaurants, historical mansion restorations, and office entrances
- As an application tip; you can combine this arch with half columns or decorative corbels to create magnificent door portals, bringing the noble atmosphere of ancient architecture to your transitions
- For the installation of the P14D30D160VI curved arch, the application surface must first be completely free of dust, moisture, and dirt, and must be dry and smooth
- The ends of the arch are precisely measured according to the installation area and cut with a standard saw if necessary
- Polure Polfix adhesive, which provides strong adhesion, is applied in strips to the back surface of the product
- After placing the arch on the wall or facade, mechanical fastening using screws is mandatory to prevent slipping while waiting for the adhesive to dry
- Screw heads and joints are filled with high-quality exterior putty
- Once the putty dries, it is smoothed with 180-220 grit sandpaper
- An additional primer can optionally be applied over the factory-applied primer; then, the installation is completed by applying at least two coats of water-based or synthetic paint
- Maintenance of the polyurethane arch profile is extremely practical
- Dust accumulated indoors can be easily cleaned with a damp cloth
- For exterior applications, it is recommended to inspect the paint surface once a year and clean it as needed
- Although it has high impact resistance, it should be protected from direct contact with sharp and pointed objects
- Abrasive acidic chemicals or stiff brushes should not be used during cleaning; mild soapy water and a soft sponge are sufficient
- There is no harm in washing it with pressurized water on exterior surfaces
Will it be damaged by sunlight when used on the exterior?
If the product is exposed to direct sunlight (UV) without paint, it may yellow over time. Therefore, in exterior applications, it must be painted with two coats of high-quality UV-resistant exterior paint after installation. Once painted, the product shows resistance to sunlight, extreme temperatures, and frost.
Is it mandatory to use screws during installation, or is adhesive alone sufficient?
Yes, mechanical fastening with screws is mandatory. Due to its curved structure and dimensions, screw support is essential to ensure the product sits perfectly on the surface and does not slip until the adhesive dries. Once dry, the screw holes are filled with putty to conceal them.
Is the product ready for painting, or is an additional primer required?
Our product is shipped from the factory with a special primer applied, making its surface directly ready for painting. However, since paint manufacturers do not guarantee paint jobs done without their own primers, applying an additional primer is entirely up to the customer's preference.
What advantages does it have over plaster or wood alternatives?
Compared to plaster arches, it is much lighter and shatterproof, making installation practical and clean. Unlike wood alternatives, it handles damp conditions well and is less susceptible to insect damage, warping, or cracking over time. Additionally, it is not soft like EPS styrofoam products, offering high impact resistance.
Can it be cut and shortened according to the desired dimensions?
Yes, polyurethane material can be processed just like wood. Using a standard miter saw or hand saw, you can easily shorten and adapt it to the width of your installation area by cutting from the ends of the arch.
