The decorative architectural element with reference code P1456D44VID blends the classic circular arch form with modern engineering. Featuring a prominent central keystone and a stepped curved profile, it creates a deep portal effect on any surface. It is highly preferred for door tops, hallways, and window trim systems to provide a structural load-bearing look.
Manufactured from high-density (150-200 kg/m³) rigid polyurethane, this product offers a perfect semi-circular shape with a 170 mm profile thickness, 840 mm span width, and 420 mm arch height. Despite having a hardness comparable to wood, its lightweight design prevents any extra load on the building structure during installation. Thanks to its closed-cell structure, its water absorption rate is under 1%, preventing issues like moisture, rot, mold, or dimensional warping.
The smooth surface texture and clean lines make it a balanced transition element in both classical/neoclassical restoration projects and eclectic modern designs. The factory-applied white protective primer prepares the surface for the final coat of paint. The symmetry of the circular form creates a visual focal point on facades, enhancing architectural prestige.
It is suitable for both highlighting indoor room transitions and framing outdoor windows. It has a wide range of applications, including villa facades, hotel lobbies, restaurant entrances, and historical building restorations. For outdoor applications, it must be coated with high UV-resistant exterior paint to ensure the material retains its shape and resists sun damage over the years.
Compared to heavy concrete, plaster, or marble alternatives, it offers a much more practical, clean, and fast installation process. For structural stability, using Polure Polfix polyurethane adhesive and mechanical fastening with screws is essential. While the factory primer supports paint adhesion, applying an additional primer coat is optional and depends on the user's preference for optimal paint performance and paint brand warranty terms.
- This round arch with a keystone is a decorative trim element used to crown doors and windows in both interior and exterior areas of buildings
- On exteriors, especially in private villas, residential, and hotel projects, it is placed above windows as a curved pediment to enhance the classical facade character
- Indoors, it is ideal for creating arched transition corridors instead of standard door frames in spacious living rooms and hallways
- It can also be creatively used as a decorative framing element in niche designs above fireplaces or on the wall behind headboards
- The curved surface for installation must be completely free of dust, moisture, and grease
- Apply Polure Polfix polyurethane assembly adhesive to the back of the product
- Once the arch is positioned on the wall, mechanical fastening with screws at specific points is required to prevent slipping until the adhesive cures
- Screw heads and joints should be filled with exterior-grade acrylic filler, and once dry, sanded smooth with 180-220 grit sandpaper
- An additional coat of primer is recommended in line with the paint manufacturers' system warranties; the process is then completed with at least two coats of water-based or synthetic paint
- Using UV-resistant paint is mandatory for outdoor applications
- The product can be easily cleaned using a damp cloth or a soft, non-abrasive sponge
- Avoid using strong acids, solvent-based thinners, or abrasive chemicals during cleaning
- For exterior applications, it is recommended to inspect the painted surface every few years and touch it up if necessary to maintain paint integrity and UV protection
