The gaps between sash frame are the primary cause of draughts. They can also cause noise and rattling, which can reduce soundproofing. Sealing beads, special products and secondary glazing can all be used to minimize the air leakage within a 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 can lead to moisture leaking in the wood, rotting and the growth of mould. The gap can be sealed with silicone or polyurethane caulking or foam sealant.
If a gap in the window is preventing the windows from closing and opening easily, it could be necessary to install new sash runners or spring bronze. These bronze strips are tied or stapled to the lower sash edges in order to prevent the rattling of the sides. They can be bought at DIY stores. Tubular weatherstripping also can be used, however it tends to rip and may alter the look of your window.
When replacing sash runners, it is important to take full measurements of the window opening. It is recommended to measure from the top of the sash up to the horizontal centerline of the rails that meet, and from the bottom of the sash down to the sill. These measurements can be incorporated into the new runners, which will ensure a perfect fit and better operation of the window.
In older buildings the gap between the frame and sash is typically wider around the leading edge. It can be draught proofed by using a self-adhesive Vstrip, however it is crucial to account for this when cutting and measuring the material.
The strip should be cut at the height of the sash, with an inch more on each side to allow for movement. It should be cut squarely and positioned to align with the angle of the sill. It is also important to use stainless steel screws since brass can rust and a high-quality silicone or polyurethane adhesive.
Refurbishment
The Sash window is a beautiful historical feature in many homes. But despite their beauty, these windows are prone to a myriad of issues. Common issues include rattling draughts or sticking.

A full refurbishment can also include adding draught proofing, re-attaching the sash furniture/ironmongery and replacing the parting bead (the dividing strip between the two panes of glass). It is also recommended to put in brush pile weather strips in order to minimize rattle and increase insulation.
If a new sash is needed, it can be made with the same design to match your old frame. This will help preserve the traditional style of your property. This is particularly important for listed buildings where any changes to windows will require planning permission.
Compare the metal tabs of the new window to the old sash prior to installing it (see below). If the tabs are different shapes, the new sash won't fit properly into the slots of the window frame.
It is crucial to determine whether to repair or replace a damaged window, as each will require a different degree and cost of expertise. For instance, if a sash window has a significant piece of glass missing then replacement is the best choice. If the glass is only damaged in a small area or a sill is rotting or rotting, then a repair could be more appropriate.

A poor seal can also be fixed by a few easy fixes instead of a costly full frame tear-out and replacement.

A specialist can help restore windows made of sash to their original splendor, or even bring them up to current energy standards. This may include reconditioning the frames and fitting secondary glass to prevent heat from escaping through the window. It may also be beneficial to put in a brush pile strip to stop rattling and reduce drafts.
To begin a repair project take out the window stops (the moldings on the front of the lower sash). Then, loosen the staff bead, then remove the lower sash. Remove the chains and cords from both sides. Finally, disconnect the sash weights from the bottom of the cavity and remove them. Keep the hardware in a secure position. The heat gun will soften old, hardened filler or putty. Scrape it away with the blade of a putty.

Getting the window to come apart begins with the removal of any security fittings in front of the lower sash. Then, take off the staff bead. Then, remove the sash at the bottom. Then, pull out the chains or cords on both sides and knot them to prevent them being pulled back into the frame by the attached weights. The next step is to take out the upper sash. Take out the sash stops, a thin vertical strip of wood that is used to hold the sash. Also, remove any painted-covered hardware. Pull the sash to reveal the balancing weight which is a heavy iron cylinder that is encased in a hidden cavity and held by a rope. To stop the sash from falling into the void, pierce it with a nail and then let the weight go.
After the sashes are removed clean the jambs as well as the rails that meet. Remove the glazing bars and the cords of the sash. Then employing a utility blade take off any paint that is on the sash stop. After the sashes have been put returned to their original positions, you can attach the stops using nails that are small enough to prevent puncturing the weight that is balancing.
To reassemble the sash place the top sash onto its track first, and then the lower sash. Make sure that the sash stops are in the correct alignment with the frame, and reattach the parting beads if needed. Then, reconnect the sash cords or chains and then re-attach the axles of the sash pulleys.
