Mortarless Glass Block Grid Walls

Today's architects and designers are always looking to reduce the carbon footprint of their project. With that goal in mind, GBA has introduced our new Mortarless Glass Block Grid system. The integral metal framework of this system provides strength for any size wall or window with no visible mullions or grout joints. Leveraging function and design, the Mortarless Glass Block Grid System offers designers and architects a versatile structure that fits any setting, window or wall. Enhanced light transmission and clean lines are created through an internal steel or aluminum grid.

The idea for a glass grid system of this nature was derived from the idea of hidden framing structure. This system is perfect for interior/exterior use as a window, wall, and even for exterior windscreens. Glass bricks can be laid within this system in addition to traditional glass block. The steel or aluminum grid can be customized to have the brick laid in a stack bond or running bond option.
