Typical Details and Code Limitations

A. Hollow glass blocks, Standard Series - 3 7/8" thick, Thinline Series - 3 1/8" thick and special shapes. All blocks are designed for a modular face dimension of 4", 6", 8" and 12" using 1/4" thick mortar joints.

B. Mortar shall conform to ASTM C270 Type 'S' for maximum bond strength.

C. Horizontal reinforcing for Standard Series to be 2" wide of two 9 gauge parallel wires with cross ties at 8" o.c. Reinforcing for Thinline Series to be 1 5/8" wide. All reinforcing to have hot dipped zinc coating. Horizontal reinforcing to have a maximum spacing of 18" o.c., i.e. every third joint at 6" block, every other joint at 8" block and every joint at 12" block.

D. Panel anchors to be 1 3/4" x 24" x 20 gauge steel with elongated perforations and hot dipped zinc coating. Locate panel anchors in same joint as horizontal reinforcing. Panel anchor to be installed in horizontal joint of masonry wall if possible and embedded 12". For alternate connection, return panel anchor up face of jamb and add two 1/4" anchors with washers just above bend of anchor. Anchors to be in horizontal alignment.

E. Aluminum channels with panel anchors are an acceptable alternate.

F. Head and jamb channel to be 1 1/2" x 4 1/2" x 14 gauge for Standard Series and 1 1/2" x 3 3/4" x 14 gauge for Thinline Series. Channels used for exterior installations should have hot dipped zinc coating.

G. All glass block panels to be non-load bearing and isolated from surrounding structures/walls with 3/8" thick glass fiber or white polyethylene foam expansion strips at jambs and head. Sill to be coated with asphalt emulsion to serve as a bond breaker.

H. Structural members around glass block panels shall be limited to a deflection of L/600.

I. Provide for vertical expansion joints where straight walls and curved walls (radius larger than 24") intersect or at a reversal of the curved wall.

J. Expansion material at jambs may be omitted for panels with areas of 25 sq.ft. or less. Expansion joint at head must be maintained.

K. All steel on the outside, within the wall system and adjacent to wall on inside should have a coating of hot dipped zinc to minimize rust staining.

L. Silicone sealant may be used in lieu of mortar in which the exposed joints are approximately 1/8" thick and panels are limited to 25 square feet on exterior and 85 square feet on interior installations.

M. Limitation of panel sizes:

1. Exterior wall panels using Standard Series (3 7/8" thick) block exposed to 20 lbs./square foot wind load to be limited to 144 square feet when supported on all four sides. Area may be increased to 250 square feet when an intermediate stiffener is incorporated as an additional supporting member near the middle of the panel and span is not longer than 10 feet. Maximum height to be 20 feet and maximum width to be 25 feet except the Uniform Building Code limits height and width to 15 feet.

2. Interior wall panels using Standard Series (3 7/8" thick) block to be limited to 250 square feet. Max. height to be 25 feet and max. width to be 25 feet except the Uniform Building Code limits height and width to 15 feet.

3. Exterior or interior wall panels using Thinline Series (3 1/8" thick) block, exposed to 20 lbs./square foot wind load or less to be limited to 85 square feet when supported on all four sides. Area may be increased to 150 square feet when an intermediate stiffener is incorporated as an additional supporting member near the middle of the panel. Maximum height is limited to 10 feet for exterior and 20 feet for interior installations. Maximum width is limited to 25 feet for exterior and interior.

4. Check governing building code for additional details.

N. Contact Glass Masonry, Inc. for design of glass block panels subjected to a wind load greater than 20 lbs./sq.ft. or for design of free standing exterior panels.
