Head Flashing Tape
• This instruction step depicts one of many options
for proper flashing.
• Moisture infiltration problems in any type of
building can be reduced by properly flashing and/
or sealing around all building openings, including
windows and doors. Proper flashing under and
around window and door openings can reduce
moisture problems, but the performance of
any building system depends upon the design
and construction of the building system in its
entirety, which should address local environment,
climate, building codes and product and material
limitations. The design and installation of flashing
and sealing systems are the responsibility of
the architect, contractor, installer, and/or the
manufacturer of the building exterior specified for
the project.
Side Flashing Tape
Unit must be properly flashed and sealed for
protection against water and air infiltration. Use
non-reflective flashings. Highly reflective flashing
tapes can raise the surface temperature of the vinyl
to the point where vinyl deformation and product
damage may occur.
