Glass wall

Extech/Exterior Technologies Inc. now offers its Gridlock glass brick wall system, designed for ease of installation and convenient maintenance in transit applications. The system’s grid design allows 2-inch-thick solid glass bricks to “snap in” place without the need for mortar, sealants or adhesives. The system adapts to various opening sizes, including long structural spans. Gridlock’s lightweight, prefabricated aluminum frames feature no exposed fasteners, and it presents clean, narrow sightlines.
