The P1456D160VID round curved arch with keystone is a premium decorative element that seamlessly blends classic architectural elegance with modern engineering for both interior transitions and exterior facade designs. Featuring a smooth semi-circular curve and a prominent trapezoidal keystone at its apex, it adds depth and structural character to any space. It serves as an aesthetic divider and frame for over-door portals, hallway transitions, or window arch decorations.
With a width of 170 mm, a span (length) of 1980 mm, and a height of 1096 mm, this arch offers ideal proportions for wide transition areas. Manufactured from high-density (150-200 kg/m³) rigid polyurethane, it matches the hardness of wood while remaining exceptionally lightweight. Thanks to its closed-cell structure, it is fully resistant to moisture, humidity, and water, preventing rotting or swelling. It maintains its dimensional stability under temperature fluctuations from -20°C to +80°C, resisting structural deformations like cracking or warping.
The design showcases stepped profile lines along the curve that merge with a sleek central keystone, creating a balanced play of light and shadow. Unlike heavy concrete or fragile plaster alternatives, this lightweight structure adds no extra load to the building, ensuring easy installation. The factory-applied primer prepares the surface for the final coat of paint. However, since paint manufacturers do not guarantee applications without their own primers, applying an additional post-installation primer is optional and at the user's discretion. Polure assumes no responsibility for the performance of the paints used.
The high durability and lightweight advantages of polyurethane make the installation process highly practical. During installation, Polure Polfix adhesive should be applied to the back surfaces and joints, followed by mechanical fastening with screws. For outdoor applications, it must be painted with a UV-resistant exterior paint to prevent yellowing caused by sunlight over time.
- The P1456D160VID round curved arch model is highly versatile, making it ideal for both interior design and exterior facade projects
- Indoors, it is frequently preferred for wide transition corridors between living rooms and entryways, framing large doorways, and crowning decorative wall niches
- It is perfect for designing grand transition portals in prestigious commercial spaces such as offices, hotel lobbies, or restaurants
- Outdoors, it can be safely used as a crowning element above villa entrance doors, for classical facade ornamentation above windows, or as decorative cladding in arched veranda openings
- Thanks to its water and moisture-resistant structure, it retains its aesthetic appeal for many years without any structural degradation in high-humidity areas like bathrooms or indoor pools
- The curved surface for installation must be completely free of dust, moisture, and dirt
- Apply Polure Polfix polyurethane adhesive to the joints of the arch pieces and the back surfaces contacting the wall
- Once positioned, mechanical fastening with screws at key points is mandatory to prevent slipping until the adhesive cures
- Screw heads should be countersunk
- After Polure Polfix dries, trim any excess adhesive, and fill screw holes and joints with a high-quality exterior filler
- Once the filler is dry, sand it smooth using 180-220 grit sandpaper
- Following an optional extra coat of primer, complete the installation by applying at least two coats of water-based paint for interiors, or UV-resistant paint for exteriors
- With near-zero water absorption, the polyurethane curved arch is extremely easy to maintain
- For indoor use, it can be cleaned periodically using a duster or a damp cloth
- For heavy dirt, mild soapy water can be safely used
- For exterior applications, it is suitable for pressure washing
- Avoid chemical solvents and abrasive acid-based cleaners
- For outdoor installations, check the joint filler and paint integrity once a year, depending on weather exposure, and apply local touch-ups or re-filling if necessary
