Draughts are mostly caused by gaps between the sash and the frame. They can also trigger rattling and reduced sound-proofing. Sealing beads, specialty products and secondary glazing can be used to limit the air leakage within a sash.

A gap between the top and bottom of the sash, and the jamb frame, double glazing repairs is an issue that is common. This can cause moisture to leak into the wood, which can cause rotting and the growth of mold. The gap can be closed by caulking made of silicone or polyurethane or foam sealant.
