Where Glass Block Shines

Glass blocks bring together what usually feels like a tradeoff: daylighting + privacy, beauty + durability, design freedom + performance. With the combination of any custom RAL color, they create a crisp, dimensional look while still letting light travel through a space.


Common Applications

  • Accent / feature walls (commercial lobbies, restaurants, offices, homes)
  • Interior partitions (room dividers)
  • Bars, bulkheads, columns, and architectural highlights

Popular Applications of Glass Block

Glass Block Walls

Many interior designers like to feature an accent wall to draw attention to a specific focal point of a room. When creating an accent wall with glass brick, design options are expanded because glass brick adds the feature of illuminating natural light. Glass Block walls are easily designed and engineered to meet any project need. The new GBA Architectural Grid features glass block or glass bricks that are laid into a hidden grid in either a stacked or running bond formation. 

Glass Block Bar Designs

The addition of glass block to any modern bar design truly makes that bar stand out. By adding LED lights to the counter, the bar's appearance will be high-end with an added ambiance.
