The gaps between the sash and frame are the primary cause of drafts. They can also lead to noise reduction and rattling. Sealing beads, special products, and secondary glazing may all be used to reduce the air leakage inside a Sash.
A common issue is a gap that exists between the top of the sash and the jamb frame, or between the bottom of sash and the sill. This can cause water leaking into the wood the wood, rotting, and mould growth. Seal the gap using silicone, polyurethane, or foam sealant.
Installing a new sash runner, or spring bronze might be necessary when a gap is preventing windows from closing and opening smoothly. These strips of bronze are tied or stapled to the lower sash edges to stop sideways rattling. They can be bought at DIY stores. Tubular vinyl weather-stripping is an alternative option, but it is prone to tear and affect the appearance of a window.
When installing replacement sash runners, it is important to measure the entire width of the window opening. It is best to take measurements from the top of the sash up to the horizontal centerline of the rails that meet, and from the bottom of the sash to the sill. These measurements can be transferred to the new runners, which will ensure a good fit and better operation of the window.
In older buildings there is a larger gap between the sash and the frame around the leading edge. It is possible to draught-proof it using a strip of V-strip which is self-adhesive. However, it is important to take this into consideration when measuring and cutting material.

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.

The sash stops must be removed and a thin strip of wood that holds the sash. Also, take off any painted-covered hardware. Pull the sash to reveal the balancing weight, which is a heavy lead or iron cylinder enclosed inside a hidden compartment and secured by rope. To prevent the sash falling into the void, you must pierce it using a nail, and sacrifice the weight.
After the sashes are removed clean the jambs as well as meet rails. Remove the glazing bars as well as the sash cords. Then employing a utility blade take off any paint from the sash stop. Reattach the stops when the sashes have been put back in place. Use nails that are small enough not to puncture the weight of the balancing.
