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 - you can remove and replace a block in under 2 minutes, since there is no need to wait for adhesive to dry. This limits 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.
