Window fittings
Latches, locks, winders and other mechanisms attached
to the window frame may need to be removed temporarily while fitting the
ClearComfort tape and membrane.
If a window fitting is in the way, just unscrew the fitting, install the tape and membrane following the instructions, and then screw the fitting back in position.
Some types of double-hung
(sash) and awning windows have a latch that projects into the frame space
when the latch is turned (this type of latch is common on the top half
of double-hung windows, for instance). If your window has this type of
latch we suggest you fit the membrane to the outside frame of the window
in question.
