The gaps between the sash and frame are the primary cause of draughts. They can also trigger rattling and reduced sound-proofing. Sealing beads, specialist products and secondary glazing can all be used to minimize the air leakage inside the shutter.

A common problem is a gap between the top of the sash and the jamb frame or between the bottom of sill and the sash. This can cause moisture to leak into the wood, which can cause rotting and growth of mold. The gap can be filled by caulking made of silicone or polyurethane or foam sealant.

If a gap in the window is preventing the windows from opening and closing smoothly, it may be necessary to replace sash runners or spring bronze. These strips of bronze are tied or stapled to the lower sash edges in order to stop sideways rattling. They can be bought at DIY stores.

It is important to take measurements of the entire window opening before installing new sash runners. It is recommended to measure from the top of the sash up to the horizontal centerline of the meeting rail and from the bottom of the sash to the sill.
