Latches, locks, winders and other mechanisms attached to the window frame may need to be removed temporarily while fitting the ClearComfort tape and membrane.

Installing clear comfort insulation around window fittings

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.
