...With All Accessories Needed to Complete Your Project

GBS has been selling glass block supplies to builders, dealers and the public for more than 15 years. We offer a wide selection of glass block and masonry supplies. We manufacture America's strongest glass block vent, and sell real glass block windows, not plastic.  

The newest, most user friendly product The Glass Block Supply Company now offers is its Clear Choice® window systems. They have set the foundation for the future. Builders no longer have to use plastic windows. Clear Choice offers REAL GLASS BLOCK in a vinyl frame with a nailing flange to easily insert into an opening. It can be finished off like all the other windows in a home. Clear Choice uses a mortarless system that combines strength and reduced weight to accommodate almost any application.
