Polyurethane Round Arch and Keystone Model

The Polure P1456D44VIC polyurethane round arch is a premium decorative element designed to bring classic depth to architectural openings such as doorways and windows. Featuring an integrated keystone motif, this piece brings the majestic transition lines of ancient Roman and Ottoman architecture into contemporary living spaces. It creates a distinctive focal point that transforms the character of buildings in both interior designs and exterior facade projects.

Looking at its technical specifications, the product features a profile depth of 221 mm, an arch width (span) of 840 mm, and a height (rise) of 420 mm. These balanced dimensions ensure a perfect fit with standard-width door and window frames. Manufactured from high-density rigid polyurethane (150-220 kg/m³), the arch offers the hardness of wood while remaining exceptionally lightweight. Thanks to its closed-cell structure, it has low water absorption (below 1%), making it resistant to moisture, rain, and mold.

In terms of visual design, the smooth circular curve is framed by stepped straight lines. The keystone at the apex is adorned with acanthus leaves and elegant scroll details. These symmetrical, finely crafted reliefs add a rich sculptural effect to facades through the play of light and shadow. Produced with precision molding technology, its smooth surface contours offer a seamless integration on any applied surface.

Compared to heavy traditional plaster, marble, or stone arches, this lightweight material is extremely practical to transport and install. It adds no static load to the building structure, reducing the risk of falling during earthquakes or tremors. Furthermore, its stable structure does not warp, crack, or suffer from insect infestation over time like wood, promising long-lasting durability. This product is both an aesthetic and functional investment.

The product is delivered with a protective factory primer that prepares the surface for the final topcoat. However, since paint manufacturers do not offer warranties without their own primers, applying an additional primer is entirely at the user's discretion. Polure does not warrant the paints used. For outdoor applications, UV-resistant paints must be used to protect the material from sunlight. During installation, Polure Polfix adhesive and mechanical screwing techniques must be used together.
