Glass Block System

EXTECH has launched its Gridlock™ Glass Block System. The nearly unbreakable, 2-inch thick glass blocks snap securely into place without the use of sealants or adhesives. Installation and maintenance are quick and easy using lightweight, prefabricated, aluminum frames with no exposed fasteners. With no ledges to collect dirt and debris, and superior graffiti resistance, cleaning requires only a simple pressure wash. Unlike mortared systems, joints will not deteriorate, effloresce, collect dirt or discolor. Gridlock framing is adaptable to various opening sizes including long structural spans. The clean, narrow sightlines are available in frames of unlimited colors. Block options include etched or back screened. For more information, visit www.extechinc.com.
