The P1456D75VID curved arch is a structural decorative element that seamlessly blends classic architectural style with modern manufacturing technology for both interior and exterior transitions. Designed to create an elegant curve over doors, windows, and hallway openings, this model adds depth to structures with its prominent central keystone detail. By softening straight lines, it establishes a fluid visual bridge between spaces while creating an optical illusion that makes ceilings appear higher. It is the ideal design component for architects looking to bring the noble presence of traditional stonework into modern living spaces.
The product features balanced proportions with a profile depth of 170 mm, a span width of 1150 mm, and a total height of 671 mm. It is manufactured to high standards of 150-220 kg/m³ (production target ~160 kg/m³) using high-density rigid polyurethane raw material. Include the product weight and fixing loads when assessing the substrate and supporting structure. Thanks to its closed-cell structure, it is completely resistant to moisture, humidity, and water. Consequently, it does not suffer from deformations such as cracking, flaking, swelling, or insect infestation over time, maintaining its original form for many years.
In its visual design, the stepped curved profile lines merge with a trapezoidal keystone that widens at the apex. This symmetrical structure delivers the aesthetics of traditional stone carving with smooth, clean lines. The stepped transitions, which beautifully capture the play of light and shadow, create a rich relief effect on the facade. It is frequently preferred to enhance facade character in both historical restoration projects and modern neoclassical designs, giving an architectural identity to ordinary wall transitions.
Offering a wide range of applications, this structural element finds its place on the exterior windows of luxury residential projects, as pediments over villa entrance doors, or in interior transitions of living rooms, halls, and corridors. It is also used as a dividing arch in hotel lobbies, restaurant niches, and prestigious office projects. Thanks to its complete resistance to water and outdoor weather conditions, it can be safely installed on both interiors and exteriors. For outdoor applications, it must be coated with UV-resistant paint to protect the material from the effects of solar radiation.
During the installation phase, it is crucial that the surface is dry and clean. After securing the product to the surface with Polure Polfix adhesive, the installation is reinforced with mechanical screw anchoring. Once the screw heads and joints are filled with exterior-grade putty and smoothed with 180-220 grit sandpaper, the painting process can begin. The factory-applied primer coat facilitates paint adhesion. However, applying an additional coat of primer remains optional under the application standards and warranties of paint manufacturers, leaving the choice entirely to the installer.
- This decorative curved arch has a wide range of applications in both interior and exterior designs
- On exteriors, it is used as a complementary crown for window architraves, particularly above arched windows of prestigious buildings such as villas, mansions, and hotels
- It is ideal for creating a grand portal effect over main entrance doors
- Indoors, it is applied as a doorless transition arch between living and dining rooms or in wide corridor halls
- It is also an excellent architectural element for creating spatial focal points, such as a curved frame on the wall behind a bedhead or in decorative niche designs behind a fireplace
- Before installation, the wall or facade surface must be completely cleared of dust and moisture
- Apply Polure Polfix adhesive in strips to the back of the curved arch profile and position it on the wall
- For safety and durability, mechanical fastening with screws is mandatory
- Screw holes and joints should be filled with an exterior-grade acrylic putty
- Once the putty dries, smooth it with 180-220 grit sandpaper
- An optional additional coat of primer can be applied over the factory primer, followed by at least two coats of water-based or synthetic paint to complete the process
- Once installed and painted, the product requires minimal maintenance
- For interior use, dusting with a soft, damp cloth is sufficient for cleaning
- For exterior applications, the painted surface should be inspected once a year, and local paint touch-ups should be applied if necessary to protect against solar radiation
- Abrasive chemicals, acidic detergents, and high-pressure washers must not be used during cleaning
Will the P1456D75VID arch model be affected by rain and sun on the exterior?
Since the product is manufactured from high-density rigid polyurethane with a closed-cell structure, it is completely resistant to water and moisture, preventing rotting or swelling. However, to protect it from solar UV rays, it must be coated with a high-quality, UV-resistant exterior paint.
How easy is this product to install compared to plaster arches?
Plaster arches are extremely heavy and fragile, carrying a high risk of cracking during installation. In contrast, this polyurethane arch is as tough as wood yet very lightweight. It can be installed quickly, cleanly, and without any risk of breakage using Polure Polfix adhesive and screws.
Is the keystone on the arch added separately?
No, the P1456D75VID model is produced as a single, monoblock piece with its curved body and the trapezoidal keystone detail at the apex. This ensures ease of installation and eliminates the risk of cracking at the joints.
Can I use only silicone adhesive to install the product?
No, using only silicone for installation is strongly discouraged. For a secure and permanent bond, Polure Polfix polyurethane adhesive must be used, supplemented by mechanical fastening with screws.
Is the product delivered painted, and is priming necessary?
Our product is shipped from the factory with a special white primer coating. This primer facilitates paint adhesion. Applying an additional coat of primer before painting is optional; the decision depends on your preference and the warranty conditions of your paint brand.
