window trim corner blocks
Window trim corner blocks are essential architectural elements used to seamlessly connect vertical and horizontal molding profiles around windows and doors. Designed for exterior facades, these corner joints prevent water infiltration and cover unsightly gaps at connection points. Compared to traditional plaster or concrete, polyurethane window trim corners are exceptionally lightweight, highly durable, and resistant to moisture, UV rays, and impacts. They do not crack, peel, or rot over time, making them a long-lasting solution that can be easily painted with any exterior paint and quickly installed using adhesive. Polure’s high-density polyurethane corner blocks offer millimetric precision and a smooth surface finish, elevating the aesthetic value of any exterior design project.
