Custom Windows at Quality Glass Block and Window Company, who is the industry leader in preassembled glass block panels, offers many patterns that provide ample light and high levels of privacy.

Our warranty-backed glass blocks are made by industry leader Seves Glass Block.

Why We Are Leaders in Glass Block Panels

  • Preassembled windows. Quality Glass Block and Window Company provides customers with preassembled panels crafted from Seves Glass Block. We offer customers the choice of standard or custom sizes, both with and without ventilation.
  • Four distinct patterns. We offer three unique patterns that provide varying degrees of light transmission and privacy: Diamond DM Pattern, Icy Pattern, Nubio Pattern Alpha Pattern and Clarity Pattern.
  • 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 don’t rust, they don’t rot and the frame doesn’t 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 company provides a comprehensive variety of patterns, styles and sizes. When the glass blocks are used exclusively with Seves Glass Block accessories, the company backs its products with a five-year warranty.
