About Mortarless Glass Block

Mortarless Glass Block

Glass Block Windows & Walls

Industrial, Commercial and Transit Glass Block Systems

EXTECH® has developed a series of mortarless framing systems for use with glass blocks, most often solid glass blocks 8" x 8" x 1 1/2" (or 3") thick.  These provide ideal walls or screens for applications where low maintenance and vandal resistance are important.

These solid glass blocks can be factory installed in relatively small framing units (for example, using nine blocks) and the pre-assembled units can then be snapped into aluminum receptor systems in the field.  Alternatively, the EXTECH® aluminum framing can be sent to the job site pre-assembled and the glass blocks then installed in the field.

EXTECH's patented glass block walls and window are easy to erect, maintain and replace. Mortar-less glass block systems are ideal for industrial and transit applications. With aluminum framing the glass block walls are durable and perfectly aligned.

The benefits:

  • Exposed aluminum will not deteriorate like mortared joints do
  • Available in a variety of finishes 
  • Blocks available in various sizes for design flexibility
  • Replaced blocks look just like old blocks
  • Quick and easy installation
  • Easy to maintain
  • Vandalism and graffiti resistant
  • Most of our systems utilize SOLID glass blocks, which are 1- ½”, 2” or 3” thick.
