Specially developed for wide-span transition areas and grand facade designs, this polyurethane curved arch profile is an architectural element that adds depth to building entrances and windows. Thanks to its large-scale circular form, it offers an aesthetic frame that supports structural integrity in both interior partitions and exterior facade decorations. Combining the round contours of classical architecture with modern production technology, this profile is ideal for elegantly crowning wide openings.
The product is manufactured using high-density rigid polyurethane raw material with a density of 150-220 kg/m³. This high density provides the product with a surface durability comparable to wood, while offering a lightweight structure that ensures ease of installation and transport. Measuring 193 mm in width, 4605 mm in arc length, and 2302 mm in vertical height, this massive arch features a closed-cell structure with a water absorption rate of less than 1%. Consequently, it maintains its form without expanding, shrinking, cracking, or warping; dimensional stability has been tested within -20 °C / +70 °C.
Its visual design features a smooth, stepped, and curved profile structure. Thanks to precision mold technology, the surface lines are exceptionally sharp and clean. The product is shipped from the factory pre-primed with a special white surface primer. This primer coat enhances the adhesion of the topcoat paint. However, since paint manufacturers do not offer warranties for applications done without their own primers, applying an additional primer before or after installation is entirely at the user's discretion. Polure does not assume responsibility for the performance of subsequently applied paints.
This model is highly preferred for main entrance doors of large-scale villas, wide arched transitions in hotel lobbies, historical restoration projects, and partition walls of high-ceilinged halls. It can also be safely used on exterior facades as a curved lintel frame over wide windows. Thanks to its lightweight nature, it does not add extra static load to the building's load-bearing system like its concrete or stone counterparts, offering a significant advantage for seismic safety.
During installation, Polure Polfix polyurethane adhesive must be applied to the cleaned and dry surface, followed by mechanical fastening to the wall with screws. Silicon-based adhesives must strictly be avoided. Once screw holes and joints are filled with flexible filler and smoothed with 180-220 grit sandpaper, the painting process can begin. Since unpainted products may yellow over time, using a UV-resistant topcoat paint is mandatory, especially for exterior applications.
