Draughts are mainly caused by gaps between the sash and the frame. They can also cause rattling and reduced sound-proofing. Sealing beads, special products, and secondary glazing may all be used to minimize the air leakage in a shutter.

A gap between the top or bottom of the sash and the jamb frame, is an issue that is common. This could cause moisture to leak into the wood, rotting it and growth of mold. Seal the gap using silicone, polyurethane or foam sealant.

Installing new sash runner or spring bronze could be required in the event that a gap blocks the windows from opening and shutting smoothly.

In older structures there is a larger gap between the sash and the frame on the leading edge. It can be draught-proofed by using strips of V-strip that is self-adhesive. However it is essential to take this into consideration when measuring and cutting material.

The strip should be cut to the height of the sash and with an inch added on each side to allow for movement. The strip should be cut to a square shape and then positioned so that the ends are matched to the angle of the window sill. Make sure to use stainless steel screws since brass may rust. Also, use a high quality polyurethane or silicone glue.

Unscrew the sash stoppers (a thin vertical strip of wood that supports the sash) and loosen any paint-encrusted hardware. Reverse the sash to reveal the weight. It is a heavy iron or lead cylinder that is concealed inside a cavity and held by a cord. To keep the sash from falling into the void pierce it with nails and remove the weight.
