SunBlock Plus Windows
Hy-Lite upgraded the original SunBlock design with even more powerful UV inhibitors inside the resin to reduce solar heat gain coefficients to as low as .19. Windows come in two acrylic block sizes: 8 x 8 x 1 ½ inches and 9 x 9 x 1 ½ inches. They can be custom-cut to fit virtually any size or shape opening.
