GBA ARCHITECTURAL GRID

Mortarless Glass Block & Brick Walls, Reimagined

A precision steel grid and structural silicone system that delivers uninterrupted, mortar-free glass surfaces — beautiful, modern, and built to last.

The GBA Architectural Grid is a next-generation installation system engineered to overcome the limitations of traditional glass block and glass brick construction. Instead of mortar, it uses a precision-engineered steel grid with structural silicone — resulting in a seamless, all-glass aesthetic that mortar joints simply cannot achieve.

Each glass unit sits in its own cell within the grid, allowing for unlimited panel spans, single-side installation, and easy individual block replacement without disturbing surrounding units. Stack or running bond layouts are both supported, and the system integrates seamlessly into feature walls, partitions, and backlit installations.

“As the Senior Project Manager for the general contracting company responsible for completing all aspects of the historical restoration, structural rehabilitation, and adaptive reuse modifications to the derelict Triboro tuberculosis hospital, one of the most difficult challenges was finding capable and qualified subcontractors for the key restoration trades that are both committed to quality construction and respectful of the historical restoration process.

If only more companies active on site would follow in your companies steps these buildings would be cut and dry and run very efficiently. Thank you! – Jake M. Behler, Cameron General Contractors
