How To Install My Pittsburgh Corning Glass Block

Installing glass block gives an alternative to a solid wall construction.

Pittsburgh Corning glass block systems provide the advantage of a dividing surface and window type addition in the same space. They can be used as dividing walls that don't block light, as shower enclosures, as bathroom windows to provide privacy or as basement windows. The glass blocks are thicker than windows, providing more insulation. If you choose a style that is not transparent they can provide light without anyone being able to see into the area enclosed. Installing them is not difficult.

Things You'll Need

• Measuring tape
• Level
• Glass blocks
• Block spacers
• Mortar
• Mortar pan
• Trowel
• Foam paintbrush
• Silicone caulk

Instructions

1. Measure the area where the glass block will be installed. Determine the size and shape of the glass block you wish to install. Common sizes range from 4-by-8 inch blocks to 8-by-8 inch blocks. The typical shape is square; however, they also come in other shapes such as curved corner, triangular for corners or even rectangular for angled walls.

2. Purchase the amount and style of blocks in an adequate number to complete the job. Include the spacers, mortar and other materials in the same purchase to be sure everything needed for the job is in supply. Consult a sales associate to be sure you have accurately calculated supplies needed.

3. Prepare the surface of the area where the installation will take place. If it is a wall type installation on a floor, prepare the floor surface and install the frame for the area. The manufacturer suggests building a curb for a floor installation to avoid things such as vacuum cleaners hitting the wall.

4. Insert the spacers needed to begin the first row. Consult the manufacturer's manual to choose the correct diagram for installing the spacers. The number and type of spacers depends on the type of wall you are building and the size. A small enclosed window will have a different spacer diagram than a glass block wall.

5. Add blocks and spacers until the first row is completed. Place a layer of mortar on the first row and begin the second row. Continue to add blocks, spacers and mortar to complete the project area using the recommended diagram.

6. Finish the wall or window space and allow the mortar to dry. Caulk the glass block perimeter. Add trim or glass block wall siding to hide the frame if desired. This siding is especially made to add a trimmed look to a finished glass wall, especially one that is free-standing.
