Sealing
Sash windows can look stunning in old buildings, however they require maintenance and can be subject to problems like wet rot, cracked putty, and drafts. It is possible to minimize energy loss and increase the efficiency of windows made of sash by replacing the windows, repairing or sealing them.
Draughts are mostly caused by gaps between the sash and the frame. They can also trigger noise and rattling, which can reduce soundproofing. Different methods can be employed to limit air leaks within the sash window, such as sealing beads, specialty products, and secondary glazing.
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, which can cause rotting and growth of mold. The gap can be filled with caulking made of polyurethane or silicone or foam sealant.
If a gap in the window is preventing the windows from opening and closing without a hitch, it might be necessary to put in new sash runners or spring bronze. These strips of bronze are tied or stapled to the lower sash edges in order to prevent sideways rattling. They can be purchased at DIY stores. Weatherstripping made of tubular vinyl can also be used, but it tends to rip and can alter the appearance of your window.

It is recommended to take measurements from the top of the sash up to the horizontal line on the rail that connects them and from the bottom of sash down to the sill. These measurements can be incorporated into the new runners, which will help ensure a proper fit and better operation of the window.
In older buildings there is a greater gap between the sash as well as the frame at the leading edge. It can be draught-proofed by using a strip of V-strip that is self-adhesive. However, it is important to take this into account when cutting and measuring material.
A strip must be cut to the width of the sash, with an extra inch each side to allow for movement. It should be cut square and positioned so that the ends are matched to the angle of the window sill.
