Draughts are mainly caused by gaps between the sash and the frame. They can also lead to rattling and reduced sound-proofing. Different methods can be employed to stop air leaks from the sash window, such as sealing beads, specialty products and secondary glazing.
A common problem is a gap between the top of the sash and the jamb frame or the bottom of the sash and the sill. This can result in moisture leaking in the wood, rotting, and mould growth. Seal the gap using silicone, polyurethane, or foam sealant.
If a gap is preventing the windows from closing and opening smoothly, it may be necessary to put in new sash runners or spring bronze.
