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.  These glass block windows utilize the European Clear Glass Block Collection.

  • Twenty one distinct patterns. Quality Glass Block preassembles all 21 glass block patterns in the European Collection using specialized glass block silicone that is mold and mildew resistant.  All patterns are available with white vents or as a solid window with no vent.

  • 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 do not rust or deteriorate. 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.

If you are a contractor, architect, home owner, builder or a do-it-yourselfer, these glass block windows will bring style and security to your next project.  Contact Quality Glass Block and Window to learn more about our product lines and accessories today.
