It keeps drafts from blowing through the gaps, making your house too cold or let noise from outside into. You can purchase ready-to-use material in different sizes or cut it to fit window sashes.
For single-hung windows, place the strip between the joining rail and sash, and the same between the upper and lower sashes. In addition, install the same strips on the sides of the frame to prevent rattle.
Weather strips are required on both sides of double-hung windows. You may need to add strips within the frame at the bottom. The strips stop the window from snapping shut and also prevent dust and insects from blowing through the gap between the jamb and sash.

Then, if the pockets on each side of the frame remain in place, prise them out using the hammer and nail set or the help of a Crowbar. You may also need to remove some of the old sash material.
