Accessories
• Glass Block Anchors—to secure installation to surrounding frame. When
installing 6" (150 mm) block, set anchors 18" (450 mm) apart; for 8" (200 mm)
block, set anchors every 16" (400 mm); and for 12" (300 mm) block, set
anchors 24" (600 mm) apart. Attach short arm of anchor to jambs and heads,
with long arm extending a minimum of 9" (225 mm) into the joint.
• Glass Block Reinforcing—to strengthen glass block installation. Place in the
same joint as anchors, along the entire length of joint.
• Expansion Strips—made of dense, fibrous glass or white polyethylene, inserted
at heads and jambs to allow panel expansion and contraction.
• Glass Block Spacers—plastic or galvanized steel spacers speed installation
and promote uniform joint spacing. Plastic spacers are used for vertical
and horizontal joint alignment, galvanized steel spacers are used for
horizontal joints only.
• Asphalt Emulsion Adhesive—used for bonding expansion strips to head and
jambs to isolate glass block from framing.
Substrate Preparation
All framing, pocket recesses or chases must be complete, accurately placed and
measured to correct dimension prior to receiving glass block. The opening should
equal the nominal length and height [including the ¼" (6 mm) mortar joints] of the
total number of blocks that will fit, plus ½" (12 mm). Clean glass blocks, removing
any foreign substances to promote a proper mortar bond. Pre-plan the installation
to determine where anchors and reinforcing will be placed. Anchors should be
cut to 12" (300 mm) lengths, bent to produce a short arm [3" (75 mm)] and a
long arm [9" (225 mm)]. Attach short arm of anchor to jambs and head, with
long arm extending into joint. Follow anchor spacing requirements as outlined in
the accessories section above. Reinforcing should extend the entire length of the
glass block row. When more than one reinforcing bar is required per joint, overlap
the reinforcing at least 6" (150 mm).
