Mortar I System is for panels 25 square feet or less which are enclosed on all four sides by perimeter channels - perfect for a DIY glass block installation. Mortar II System is for panels larger than 25 square feet or for panels not supported on all four sides. This system uses panel reinforcing and panel anchors to tie the block together and to the surrounding structure.
We also offer the ProVantage glass block installation system using silicone and spacers.

 

Mortar I System
For Applications 25 Sq Ft or less.
Easy to use and ideal for do-it-yourself mortar applications because the channel helps keep the wall/panel level and plumb. If your application is larger than 25 sq ft you can use this method by adding panel anchors and reinforcing wire.
