Why We Are Leaders in Glass Block Panels

  • Preassembled windows. Quality Glass Block and Window Company provides customers with preassembled panels crafted from the metric sized Seves Glass Block. We offer standard sized preassembled windows that have the option for both ventolation and without ventilation.

  • Available in the Wavy pattern. This timeless classic will brighten up any room with a splash of color.

  • Energy-saving, low maintenance design. Windows from Quality Glass Block effectively eliminate the need for storm windows and reduce the amount of energy required for heating and cooling. When building with glass blocks, you do not require the additional caulking, puttying and painting that typically accompany weatherizing window fixtures. Glass blocks can not rot or rust, and the frame does not peel. Cleaning is as simple as hosing the outside and wiping the inside with a damp cloth.

  • The Seves Glass Block Promise. At Quality Glass Block and Window Company, we trust the most reliable name in the industry, Seves Glass Block.  The Seves Glass Block company backs its products with a five-year warranty.


It does not matter whether you are a builder, architect, contractor, or homeowner, the best materials and beautiful style should never be compromised.
