Exterior Window Trim
Exterior window trim is a comprehensive architectural design solution that utilizes decorative polyurethane elements—such as casings, headers, keystones, and sills—to frame and elevate the exterior windows of a building. Ideal for residential homes, hotels, and historical restorations, these window surrounds define architectural lines and complete the facade's aesthetic. Compared to traditional plaster or concrete alternatives, polyurethane window mouldings are exceptionally lightweight, adding zero structural load to the building while ensuring easy transport and handling. Thanks to their closed-cell, non-porous structure, they are highly resistant to moisture, frost, and UV rays, preventing cracking, peeling, or blistering. Easily paintable with any exterior paint and quick to install using specialized adhesives, these products significantly reduce job site labor times and costs. Polure offers a diverse range of high-density polyurethane window trim elements featuring rich design options and flawless surface details.
