Polyurethane Round Curved Arch with Keystone

The P1456D115VIB is a decorative curved arch model designed to crown doors and windows in architectural projects, featuring an elegant acanthus leaf motif keystone at its center. Adding depth to transitional spaces, this design minimizes structural load without carrying the heavy weight of traditional plaster or stonework.

With dimensions of 21.1 cm depth, 155 cm width, and 84 cm height, this product can be easily applied over wide spans. Manufactured from high-density rigid polyurethane (150-220 kg/m³), it offers durability comparable to natural wood. Its closed-cell structure keeps water absorption below 1%, making it ideal for everything from humid bathrooms to harsh exterior conditions.

The visual design features smooth, curved lines that merge with the embossed keystone detail at the apex, creating a balanced symmetry. This relief motif blends the richness of classical hand-carved masonry with modern manufacturing precision. The factory-applied white primer ensures excellent adhesion for the final topcoat. Applying an additional primer for paint manufacturer system warranties is entirely optional and at the user's discretion.

This curved arch is highly versatile, perfect for hotel lobbies, villa entrances, grand living room doorways, and exterior window pediment applications. It is widely preferred for dividing hallway transitions indoors or framing windows with a majestic touch outdoors. It serves as a stunning focal point in classical, neoclassical, or eclectic design projects.

Offering ease of installation due to its lightweight structure, the product is neither fragile like plaster nor sensitive to moisture like wood. After securing it to the mounting surface with Polure Polfix adhesive, mechanical reinforcement with screws is mandatory. Once screw holes and joints are filled with putty and sanded smooth, it can be finished with UV-resistant paints for exteriors, or water-based or synthetic paints for interiors.
