From Pittsburgh Corning:
NON-LOAD BEARING
Glass block panels are non-load
bearing; adequate provisions
must be made for support of
construction above these panels.
Panels are mortared at the sill,
with jamb and head details
designed to accommodate for
building movement and lintel
deflection. The compressive
strength (for information
purposes only) of all hollow
glass block is 400 to 600 psi.;
