Polyurethane Round Arch with Decorative Keystone

The P1456D160VIB polyurethane round arch is a premium decorative element that brings the structural balance of classical architecture to transition areas and facade designs. It creates a striking sense of depth over wide doorways, hallway transitions, or exterior windows. The balanced curve of its semi-circular form softens structural boundaries, creating an eye-catching focal point in any space.

Measuring 211 mm in depth, 1980 mm in width, and 1053 mm in height, this large-scale arch design is crafted from high-density rigid polyurethane (150-220 kg/m³), offering a durability comparable to wood. Thanks to its lightweight structure, it adds no extra static load to the building during installation and can be handled safely with a reduced risk of cracking or breaking associated with plaster or concrete alternatives. Its closed-cell structure keeps water absorption below 1%, providing resistance to rain, frost, and high humidity without rotting or decaying.

The most prominent design detail is the decorative keystone featuring an acanthus leaf motif and a circular medallion at the apex of the arch. This symmetrical, embossed motif creates a perfect contrast with the smooth, clean lines of the arch profile. Carrying the characteristic traces of classical Roman and neoclassical architecture, these details combine with a flawless surface finish to beautifully capture the interplay of light and shadow.

Suitable for both interior and exterior use, this modular arch is highly favored for grand villa entrances, hotel lobbies, restaurant archways, or interior niche designs. On exterior facades, it adds a three-dimensional character to window and portal framing. Indoors, it is the perfect choice to transform plain transitions into magnificent architectural openings.

Unlike traditional heavy materials, installing this product is exceptionally practical. It is mounted by applying Polure Polfix adhesive to the cleaned surface and securing it with mechanical screws. The product is shipped with a factory-applied protective primer that prepares the surface for painting; due to paint manufacturers' warranty conditions regarding their own primer systems, an additional coat of primer is optional. For exterior applications, using UV-resistant paint is essential to ensure the material's long-term durability.
