Classic Window Trim Corner Blocks

Classic window trim corner blocks are decorative elements designed to aesthetically complete the corner joints of window and door frames on both exterior facades and interior spaces. Used at the upper and side intersections of window and door trims, they eliminate the need for complex 45-degree miter cuts while highlighting corner transitions. Made from high-density polyurethane, these classic corner blocks offer complete resistance to harsh weather conditions, rain, frost, and UV rays. Unlike wood, they do not rot, and unlike concrete or plaster, they do not crack. Their lightweight structure ensures no extra load is added to the building facade. Easily paintable and quickly installed using exterior adhesives, these products offer significant labor savings. Polure produces high-density polyurethane window trim corners that provide maximum durability against external factors and flawless joint surfaces.
