CHOOSE YOUR PATTERN
To make sure your new window will fit
properly, measure the window opening
as if the frame were already removed.
The rough opening size should be 1/2 in
to 2 in larger than the actual size of your
Clearly Secure Glass block window. The
space between the window and the
rough opening will be filled with the
installation mortar.
Remove the window sash and then
remove the window frame by bending
the top and bottom in toward the center
or by cutting it. Remove the old mortar
sill if necessary.
Set the new window into place on top of
2 wood shims, check that it is plumb and
level, then secure it with 2 shims at the
top. If you are installing a vented
window, the vent latch should be located
on the inside at the top.
Mix the mortar according to the
instructions on the bag. Apply the mortar
around the perimeter using a grout bag
or a margin trowel. Make sure the joints
are completely full.
When the mortar begins to set, remove
the shims, fill the holes, smooth the
joints with a trowel and clean the glass
with a cloth.
When installing into wood frames, wall
ties should be nailed into the frame prior
to setting the window to give the mortar a
better grip. Tool the mortar back
approximately 1/4 in from the outside
face of the glass block, then apply
caulking between the glass block and
the wood frame.
These are general instructions. Due to
variations in window construction your installation may differ.
