Then, you can insert the sash cords into slots and holes in the lower sash. You can also put the counterweights in their pockets. You can test your work by moving the sash up and down to make sure it is moving smoothly without issue. Air and Drafts Leaks Sash windows may develop drafts or air leaks due the aging process, damage, or poor construction.

This type of joint is more complicated to disassemble and requires the use of a handsaw, a knife, or a pick to cut through the glueline. Sashes that were later made used glue, which is more simple to break apart. After the sash has been repaired then it's time to install the vinyl track in the frame.
