EXTECH's MATRIXWALL is a patented glass block wall system that’s ideal for industrial and transit applications and can take the form of a windscreen, shelter, partition, or even accent wall. Easy to install, maintain, and replace, MATRIXWALL utilizes an aluminum structural grid hidden within the joints of the blocks.  The use of solid glass blocks creates windows and walls with high-durability, resistance to vandalism, and perfect alignment.
One of MATRIXWALL’s key benefits is that it doesn’t need mortar - the glass blocks can be inserted and removed with minimal effort and equipment. MATRIXWALL incorporates a snap-on elastomeric joint cover strip, which protects the silicone from exposure to UV rays.
