property damage will result
Do not overdrive screws or
nails. Product damage may
result.
Do not overfill with low

immediately or product damage
may occur.
Do not store windows flat or in
the sun or product damage may
occur.
Use masonry screw when

application and compatibility
with this product.
Do not apply any type of film
to glass. Thermal stress
conditions resulting in glass
damage could occur.
Weep holes must face the
exterior and must be located at
the bottom of the window or
product and/or property damage
may occur.
When insulating between
unit frame and rough opening or
between units when joining, DO
NOT over-pack batt insulation or
overfill with foam.
