Engineered installation and maintenance ease in transit applications, EXTECH/Exterior Technologies Inc. (EXTECH) has offered its GRIDLOCK glass brick wall system. Its patented 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.
Demonstrating its low maintenance, the prefabricated aluminum frames feature no exposed fasteners. Unlike mortared systems, these fully gasketed joints will not deteriorate, effloresce, collect dirt or discolor.
Validating its vandal-resistance, glass bricks successfully passed a ball drop test, where a 4-inch, 4.060-pound solid metal ball is dropped 54 inches directly on the solid glass brick without visible or structural damage.
GRIDLOCK presents narrow sightlines that enhance daylighting and visual security goals. Glass brick options include clear, etched or back-screened (painted). Its aluminum framing members can be anodized or painted in numerous colors.
In addition to its GRIDLOCK glass brick wall system, EXTECH’s other standard transportation-focused systems include CLEANWALL porcelain wall panel systems; KINETICWALL dynamic façades; SKYGARD 3300 and 3700 skylights; SKYSHADE 2500, 3100, 3700 and 8000 canopies; and TECHVENT 5300 windows for transit shelters, pedestrian walkways, protective windscreens and parking structures. All of the EXTECH systems are manufactured in Pittsburgh, and are compliant with the “Buy American” mandates Fixing America’s Surface Transportation (FAST).
