The P1473D67VI decorative architectural element is a circular curved arch designed to create classic architectural lines over door openings and windows. With a width of 240 mm, a span of 1756 mm, and a height of 878 mm, it offers a well-proportioned scale for wide transition areas. Combining traditional arch forms with modern engineering, this premium piece stands out as an architectural detail that transforms the facade and interior of any project.
Crafted from high-density rigid polyurethane (150-220 kg/m³), this product delivers the durability and hardness of wood while remaining remarkably lightweight. Thanks to its closed-cell structure, it features an exceptionally low water absorption rate of under one percent. This ensures the arch maintains its structural integrity for years without swelling, rotting, or cracking, whether installed in humid interiors or exposed to harsh outdoor elements. Additionally, its dimensional stability has been tested between -20 °C and +70 °C.
Visually, the product stands out with its smooth, sleek surface finish. Free from complex reliefs, its clean and minimalist curved profile blends seamlessly with both neoclassical and modern minimalist designs. The arch comes pre-primed in factory white, providing an excellent base for the final coat of paint. While this primer ensures superior paint adhesion, applying an additional primer coat before the final finish remains optional based on specific paint manufacturer recommendations.
Its application possibilities are extensive. It serves as an ideal crown for arched window frames on villa facades, or as a decorative, non-load-bearing portal in hallways and living room partitions. In prestigious spaces like entry halls or hotel lobbies, it can be paired with side columns or pilasters to create grand door pediments. For historical restoration projects, it offers a lightweight, earthquake-safe alternative to heavy stone or plaster arches, eliminating unnecessary structural load.
Unlike traditional plaster, its non-brittle nature prevents cracking and waste during installation. It is also resistant to insect infestation and warping, unlike wood alternatives. For installation, simply apply Polure Polfix adhesive to the cleaned surface, followed by mechanical fastening with screws for a secure hold. Once screw holes and joints are filled and sanded smooth, the arch can be finished with UV-resistant paints for outdoor use or water-based paints for interiors.
- This round curved arch is designed to highlight transition zones in architectural projects
- Indoors, it creates decorative portals in hallway partitions, room transitions, and above spacious living room doors
- In commercial spaces such as hotel lobbies, restaurants, and office entrances, it can be combined with column capitals or pilasters to design classic arched entryways
- Externally, it serves as a sophisticated window pediment or framing element for villas, mansions, and historical buildings
- Assess water and moisture exposure using the product technical data, surface finish and installation details
- The wall or facade surface must be completely free of dust and moisture before installation
- Align the arch profile in its designated position
- Apply only Polure Polfix adhesive to the back surface
- In addition to the adhesive, mechanical fastening with screws at key points is mandatory to safely support the product's weight
- Fill screw heads and joints with acrylic exterior filler
- Once the filler is dry, sand the surface smooth using 180-220 grit sandpaper
- After optionally applying an extra coat of primer, complete the process with at least two coats of paint
- For outdoor installations, using UV-filtered paint is highly essential
- Since the product is suitable for humid conditions and can withstand contact with water, it can be easily cleaned with a damp cloth
- Avoid using abrasive chemicals, acids, or stiff brushes during cleaning, as they may damage the surface
- For exterior applications, checking and occasionally refreshing the topcoat of paint in line with the building's general maintenance schedule will keep the product looking brand new for years
Will this arch be affected by rain or sun when used outdoors?
Since the product is made of closed-cell polyurethane, its water absorption rate is under 1%, meaning it is unaffected by rain or snow and will not swell. However, because unpainted polyurethane can yellow over time under direct UV rays, it must be coated with a UV-resistant exterior paint for outdoor installations.
Which adhesive should I use during installation?
To ensure strong adhesion and proper sealing, only Polure Polfix adhesive should be used during installation. Silicone-based adhesives are not recommended as they do not provide long-term bonding to polyurethane surfaces. Additionally, mechanical fastening with screws is required alongside the adhesive.
What are the advantages of this product compared to plaster arches?
Plaster arches are extremely heavy and fragile, making them prone to damage during transport and installation. In contrast, this polyurethane arch is remarkably lightweight yet as hard as wood, preventing cracking or breaking. Include the product weight and fixing loads when assessing the substrate and supporting structure.
Does the product come pre-painted, and what types of paint can I use?
The product is shipped pre-primed with a white factory finish. Once installed, you can paint it any color you like using water-based or emulsion paints for interiors, and acrylic or synthetic-based UV-resistant exterior paints for outdoor applications.
Can the dimensions of the product be cut or shortened?
The product is manufactured in a circular mold with fixed dimensions of 240x1756x878 mm. Due to its curved design, cutting it from the middle of the arch will disrupt symmetry. However, the straight bottom ends (legs) of the arch can be carefully trimmed using standard cutting tools to fit your project's height, or extended by adding straight moulding profiles underneath.
