Polyurethane Window Trim Accessories
Polyurethane window trim accessories are decorative and structural elements—such as keystones, corbels, brackets, pediments, and window sills—used to enhance exterior window and door surrounds. They add classic architectural details to building facades, seamlessly connecting trim lines. Unlike EPS foam or concrete alternatives, high-density polyurethane accessories offer superior impact resistance, preventing cracking or denting. Their closed-cell, waterproof structure prevents rotting, freezing, and peeling over time. Lightweight and easy to install, they put no extra load on the facade and can be painted with any exterior paint. Polure offers premium, high-density polyurethane trim accessories engineered to withstand harsh weather conditions while maintaining a smooth, flawless finish.
