Draughts are usually caused by gaps between the sash and the frame. They can also trigger rattling and reduced sound-proofing. Various methods can be used to limit air leaks within a sash window, including sealing beads, specialty products and secondary glazing.
A common problem is a gap that exists between the top of the sash and the jamb frame, or the bottom of the sash and the sill. This could cause moisture to leak into the wood, which can cause rotting and growth of mold. Seal the gap using silicone, polyurethane, or foam sealant.
If a gap is hindering windows from closing and opening smoothly, it may be necessary to put in new spring bronze or sash runners.

Tubular weatherstripping also can be used, however it is more likely to tear and can alter the appearance of your window.

It should be cut to a square shape and then positioned in a way that the ends are aligned to the angle of the window sill. Use stainless steel screws since brass can rust.
