The gaps between sash frame are the primary source of drafts. They can also trigger rattling and reduced sound-proofing. Various methods can be used to reduce air leaks in a sash window, including sealing beads, specialty products and secondary glazing.
A common issue is a gap that exists between the top of the sash and the jamb frame, or between the bottom of the sash and the sill. This can cause moisture to leak into the wood, rotting it, and mold growth. The gap can be filled by caulking made of silicone or polyurethane or foam sealant.
Installing a new sash runner, or spring bronze could be necessary when a gap is preventing windows from opening and shutting smoothly. These are bronze strips that are stapled or nailed into the edges of the lower sash in order to prevent sideways rattle. They can be purchased at DIY stores. Tubular weather-stripping made of vinyl is a different option but it can tear, and can make a difference to the appearance of a window.
It is essential to measure the entire window opening prior to installing the new sash runners. It is best to take measurements from the top of the sash up to the horizontal centerline on the rail that connects them and from the bottom of sash down to the sill. These measurements can be transferred to new runners which will ensure the best fit and function of the window.
In older buildings, the gap between frames and sash is typically greater around the leading edge. It is possible to draught-proof it using strips of V-strip that is self-adhesive. However it is crucial to take this into account when cutting and measuring material.
A piece of material should be cut to the height of the sash, and with an extra inch each side to allow for movement. It should be trimmed squarely and positioned to match the angle of the sill. It is also essential to use stainless steel screws because brass is prone to rust, and a high-quality silicone or polyurethane adhesive.

Unscrew the sash stoppers (a thin vertical strip of wood that holds the sash) and loosen any paint-encrusted hardware. Reverse the sash to reveal the weight. It is a massive iron or lead cylinder that is hidden in a cavity, and held by an elastic cord. To keep the sash from falling into the void pierce it with an hammer and then sacrifice the weight.
After the sashes have been removed clean the jambs and meet rails. Remove the glazing bars and the cords of the sash. Then, using a utility blade, remove any paint from the sash stop.
