The gaps between sash and frame are the primary source of draughts. They can also lead to rattles and reduce sound-proofing. Sealing beads, specialist products, and secondary glazing can be used to limit the air leakage in the shutter.

A common issue 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 in, rotting wood and growth of mold. The gap can be filled by caulking made of silicone or polyurethane or foam sealant.

Getting the window to come apart begins with the removal of any security fittings on the front of the lower sash. Next, remove the staff bead, then pull out the bottom sash. Remove the chains and cords from both sides, and tie them in such a way that they won't be pulled back by the attached weights. Now it's time to remove the upper sash. Unscrew the sash stoppers (a thin vertical strip of wood that holds the sash) and then loosen any paint-encrusted hardware. The sash should be pulled back to reveal the weight. It is a large iron or lead cylinder that is concealed in a cavity and is supported by a cord. To prevent the sash from falling into the void pierce it with nails and remove the weight.
