Designed to crown door and window openings or define interior transitions, this decorative round curved arch (model code P1456D135VIB) is a premium architectural element. Featuring a wide curved structure and an embossed keystone detail at its apex, it creates a striking visual focal point in both traditional neoclassical facades and modern buildings.
The product is manufactured from high-density rigid polyurethane (150-200 kg/m³). With a thickness of 21.1 cm, an outer width of 175 cm, and a height of 94.4 cm, it offers perfectly balanced proportions for wide window and door openings. Thanks to its closed-cell structure, water absorption is under one percent, making it completely resistant to harsh outdoor conditions like rain, snow, or extreme humidity. It maintains its dimensional stability between -20°C and +80°C, preventing cracking or expansion.
In terms of visual design, the smooth, stepped curves of the arch blend seamlessly with the acanthus leaf motif keystone at its center. This detailed keystone adds vertical movement to the circular arch form, enhancing the perception of depth on building facades. The flawless surface quality features high detail precision, beautifully reflecting the interplay of light and shadow.
This decorative element is ideal as an arched pediment over exterior windows in private villa projects, a transition arch in hotel lobbies, or a pediment over wide living room doors. Since it adds no extra static load to the building structure, it is safely preferred over plaster or concrete alternatives in restoration projects.
For installation, Polure Polfix adhesive should be applied to the cleaned surface, followed by screws for mechanical fastening. Delivered with a factory-applied white primer, the surface is ready for painting; however, applying an extra coat of primer is optional depending on the topcoat durability and paint manufacturer warranties. For exterior applications, using UV-resistant paint is highly recommended to protect against sunlight.
- This round curved arch element serves as a crowning header in door and window framing (architrave) projects
- Thanks to its wide span, it can be positioned as a non-structural decorative arch over double-leaf villa entrance doors, wide arched windows, or open transition corridors between two halls
- It is highly preferred for decorating niches behind hotel reception desks, creating decorative wall panel combinations above fireplaces, and bringing a classic welcoming aesthetic to restaurant entrances
- On exterior facades, it can be painted with UV-resistant paint and integrated under building eaves or floor moldings
- The application surface must be completely free of dust, moisture, and grease
- Apply Polure Polfix polyurethane adhesive to the mounting surface of the arch and position the product on the wall
- Since it is a heavy and wide piece, mechanical fastening with screws is mandatory to prevent slipping during the curing process
- Screw holes and joints should be filled with an exterior-grade acrylic filler, and once dry, sanded smooth with 180-220 grit sandpaper
- After cleaning the surface, apply an optional primer according to the paint manufacturer's recommendation, followed by at least two coats of topcoat paint
- Due to its material properties, polyurethane is highly water-resistant and will not rot
- For interior spaces, it can be easily cleaned using a soft, damp cloth
- Avoid using abrasive acids or harsh chemical solvents that could damage the surface during cleaning
- For exterior applications, inspect the paint integrity once a year; if the paint surface has weathered from sunlight and outdoor elements, it can be lightly sanded and repainted to restore its original appearance
