Pittsburgh Corning Mortar Glass Block Installation System Assembly Instructions Introduction: The Mortar I System utilizes Pittsburgh Corning perimeter channels on all four sides. You will also use Universal Mortar Spacers and glass block mortar to produce clean, consistent 1/4" joints and a traditional grid look. The Mortar II System does not use the Pittsburgh Corning perimeter channels but instead utilizes expansion strips, panel reinforcing and panel anchors.
This is a reference guide for where “REGULAR” and modified spacers are used. = “REGULAR” Spacer = “FLAT” Spacer = “H” Spacer 4. Mortar Preparation The following gives an idea of the number of blocks that can be installed per 50 pound bag of mortar. White Premixed Glass Block Mortar Number of blocks per 50 lb. bag of mortar Block Sizes (Nominal) 4" x 8" 6" x 6" 6" x 8" 8" x 8" 12" x 12" No. of Premiere Series (4" thick) 34 34 30 26 18 No.
D. Use a soft, dry cloth to remove the excess film. A common household plastic scouring pad can also be used. E. Cut the expansion strip to a 1-1/2" width and insert it between the top of the blocks and the frame. 7F TOP HALF CHANNEL 7E 7G F. Apply sealant to the back of the half-section of channel and install it between the expansion strip and frame. G. Apply glass block sealant around the perimeter to seal the glass block and channel. Also seal the top channel to the frame at the head.
D. Bend each panel anchor 90° to produce a short arm (approximately 4"). 90° 4” 2D E X P A N S I O N 2E E. With scissors or utility knife, trim the expansion strip for length based on the distance between anchors. Trim the expansion strip width to 2-1/8" for Thinline® Series block and 2-7/8" width for Premiere Series block. S T R I P 3. Mortar Preparation This chart will give you an idea of the number of blocks that can be installed per 50 pound bag of mortar.
S. Install a vertical panel anchor after the second block and screw the short leg of the anchor to the curb. All panel 4S anchors should be attached using #12 x 1" zinc-plated head screws. Use two screws per anchor. Note: If attaching the panel anchors to tile or masonry, plastic screw anchors should be used. T. Apply mortar so that the long leg of the anchor is embedded in the vertical joint. 4T U.
E. Remove the previously installed “T” spacers at both jambs at the top of the second row and apply a 3/8" to 1/2" ve mortar bed on top of mocers e R pa bs this row. s m a “T” oth j b at 5E F. Install panel anchors at both jambs by completely embedding them in the mortar and fastening them to the jamb. 5F G. Reinsert the “T” spacers you previously removed. Note: Additional mortar may need to be applied to cover the anchor.
M. Screw the short leg of the anchor to the top of the opening. 5M B. With moderate pressure, run the striking tool over all the joints. It is best to strike all the horizontal joints first, then the vertical joints so that the pattern is uniform. Fill any voids with mortar. Note: Striking removes excess mortar and compacts it to create a smooth, concave, moisture-proof seal. N. Continue this two block procedure across the final row.
