The gaps between the sash and frame are the primary cause of draughts. They can also lead to noise reduction and rattling. Sealing beads, specialist products, and secondary glazing may all be used to reduce the air leakage within the shutter.
A common problem is a gap between the top of the sash and the jamb frame, or between the bottom of the sash and the sill. This could cause moisture to leak into the wood, rotting it and growth of mold. The gap can be sealed with caulking made of polyurethane or silicone or foam sealant.
If a gap is preventing the windows from opening and closing smoothly, it may be necessary to install new sash runners or spring bronze.

In older buildings, the gap between frames and sash is typically wider around the leading edge. It can be draught-proofed by a self-adhesive Vstrip, however it is essential to take this into consideration when cutting and measuring the material.
A strip must be cut to the length of the sash, and with an additional inch each side to allow to allow movement. It should be cut to a square shape and then positioned so that the ends are matched to the angle of the window sill. Use stainless steel screws as brass may be rusty.
