Consider Installation Methods When Installing Glass Block

In a previous post about installing Glass Block, we covered height, load support, and anchoring guidelines for your project. In this post, we will cover the more general issue of whether to choose an installation method that uses mortar or to do a mortar-less glass block installation; and the options within these choices.

When installing Pittsburgh Corning Glass Block, these are the four general installation methods and their specifications that you should consider.

Mortar I and Mortar II

Mortar I:Mortar GlassBlock Installation
The installation recommendations are for small residential panels of 25 sq. ft. or less. This method is not for use in constructing curved glass block walls. Interior and exterior panels must be framed on all four sides.

Note: The joints of the Mortar I and Mortar II Systems utilize a traditional installation method using a mortar finish for the classic “grid” look. Glass block sealant should be used to seal the perimeter on both sides of the panel.
