Polyurethane Round Arch Model 155 cm

This architectural element, with reference code P1456D115VI, is a specialized structural component designed to create an elegant circular contour above doors and windows. Blending classical arch architecture with modern polyurethane material technology, this piece creates a grand portal effect at entryway transitions and building entrances. Featuring a width of 1550 mm and a height of 775 mm, this curved form adds depth and classical character to any structure. Eliminating the heavy weight of traditional stonework and the installation challenges of construction sites, its lightweight design adds prestige to your projects without increasing the building's static load.

Manufactured from high-density (150-200 kg/m³) rigid foam, this curved element offers a robust, full-bodied, and deep appearance with its 137 mm wall thickness. Its durable structure, comparable to the hardness of wood, provides high resistance to impacts and external factors. Thanks to its closed-cell structure, its water absorption rate is below one percent; this ensures it retains its original form without rotting, shrinking, swelling, or cracking under harsh weather conditions such as moisture, rain, or snow. This stable nature of the material keeps maintenance costs to a minimum for many years.

The smooth, patternless flat surface design shown in the image can be freely integrated into a wide range of designs, from minimalist modern projects to historic neoclassical facades. The simple circular curved profile creates a soft and aesthetic transition on the facade through the interplay of light and shadow in daylight. These clean lines, especially when combined with side jamb profiles and column capitals, make windows the focal point of the facade, strengthening the architectural identity.

With its versatile application areas, this arch element is highly preferred for main villa entrances, large arched living room windows, transition corridors in hotel lobbies, or luxury restaurant storefronts. Being completely resistant to moisture and water, it can be safely used in high-humidity indoor spaces such as indoor pool areas, spa centers, or bathroom entryways. On exterior facades, it integrates with floor moldings and window surrounds to replicate the aesthetic of traditional stone arches above windows.

Compared to plaster alternatives, this rigid polyurethane structural element carries no risk of breakage or waste on-site, and unlike EPS styrofoam products, it cannot be damaged or hollowed out by birds, offering significant labor savings. During installation, using Polure Polfix adhesive and mechanical fastening with screws is mandatory for system safety. The factory-applied primer coat facilitates paint adhesion; however, since paint manufacturers do not offer warranties without their own primers, an additional primer coat is optional. For outdoor applications, painting with UV-resistant paint is required to prevent yellowing.
