EXTECH's GRIDLOCK is a glass block grid system that “snaps in” – no mortar, glue, or tape necessary. This snap-in technology delivers shorter installation times – no need to wait for adhesive to dry, and no disruptions to pedestrian traffic – and simplifies the installation process because no masonry is required.
The GRIDLOCK mortarless glass block system utilizes lightweight, prefabricated aluminum frames that are also easily and quickly installed – a huge advancement over traditional mortar and heavy pre-glazed systems. A variety of framing patterns and finishes allow you to create stylish structures that lock in long-term performance.
GRIDLOCK is great for industrial and transit applications, and can be used for windscreens, shelters, partitions, and even accent walls. The system utilizes 2-inch thick glass blocks, which are nearly unbreakable, provide superior graffiti resistance, and deliver the safety and comfort of daylighting.
