Custom Glass Block Windows | Quality Glass Block and Window

Preassembled Panels and Windows

Quality Glass Block and Window Company is an industry leader in preassembled glass block panels. We use American-made blocks to bring you the highest quality panels and windows that provide ample light and a high level of privacy.

Our warranty-backed glass blocks are made by industry leader Pittsburgh Corning, and our vinyl windows are made by Silver Line, an Andersen Company.

Why We Are Leaders in Glass Block Panels

  • Preassembled windows. Quality Glass Block and Window Company provides customers with preassembled panels crafted from Pittsburgh Corning 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: DELPHI® Pattern, ICECAPES® Pattern, DECORA® Pattern and Wavy Mist® 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 Pittsburgh Corning Promise. At Quality Glass Block and Window Company, we trust the most reliable name in the industry, Pittsburgh Corning. The company provides a comprehensive variety of patterns, styles and sizes. When the glass blocks are used exclusively with Pittsburgh Corning accessories, the company backs its products with a five-year warranty.
