Choose GBS for Unrivaled Inventory
At GBS, we strive to provide the broadest choice and most extensive inventory of glass block and glass brick products. Our warehouse stocks a variety of SEVES glass block patterns and sizes, including the SEVES Imperial Line, Design Line, Basic Line, and the Technology Line. We carry common sizes from Premiere Series 8″x8″x4″ glass blocks, and other 4-inch-thick options. GBS also carries less common metric sizes, including 3-inch-thick Thinline Series glass blocks.

Why SEVES?
The SEVES patented design features two sheets of low-emissivity coated glass inserts sandwiched inside the glass block, creating a two-chamber system. Air in the two chambers is replaced with argon gas. This noble gas, with its inherent thermal conductivity value, also contributes to these blocks’ increased energy efficiency. SEVES glass blocks feature the lowest U value in the industry, an indication of superior heat retention.
