Cascade’s New Vinyl Cap Stock Window is offered in a variety of shapes, sizes and configurations to meet your architectural and design needs. One of the main advantages of this process is that the color is fully fused to the frames exterior which helps reflect sunlight, while limiting the thermal heat gain. Another benefit of the manufacturing process is that it eliminates loss of adhesion to the frames exterior surface. Our Cap Stock Windows and Doors have standard lead times and come in two exterior colors, Bronze or Black over white.
