B. If installing glass block with angled wall sections
follow these steps:
• For walls with angles it is recommended that you
layout your wall before constructing a curb.
• Make sure the angled sections of your opening
or curb are congured correctly.
• The curb must be as wide as, or wider than, the
glass block thickness (4" or wider).
• Apply nish material to the curb. The curb will be
visible through the glass blocks. If installing
the glass blocks in a wet environment, take steps
to ensure that the curb is waterproof.
• Use a level to make sure the opening is level and
plumb.
• If there are any problems with the opening or
curb, adjust it before proceeding.
