Sealing

Draughts are mainly caused by gaps between the sash and the frame. They can also trigger noise and rattling, which can reduce soundproofing. There are a variety of methods to reduce air leaks in windows with sash, including sealing beads, specialist products and secondary glazing.

A common issue is a gap between the top of the sash and the jamb frame or the bottom of the sill and the sash. This can result in moisture leaking in, rotting of the wood and growth of mould. The gap can be sealed by caulking made of silicone or polyurethane or foam sealant.

If a gap in the window is preventing the windows from opening and closing easily, it could be necessary to replace sash runners or spring bronze.

In older buildings there is a greater gap between the sash and frame around the leading edge. It is possible to draught proof by a self-adhesive V-strip, but it is important to account for this when cutting and measuring the material.

A piece of material should be cut to the length of the sash. There should be an extra inch for movement. It should be cut squarely and placed to match the angle of the sill. It is also important to use stainless steel screws, as brass can rust, and high-quality silicone or polyurethane adhesive.

Refurbishment

The sash window is an elegant and historic feature of many homes. They are beautiful but they can also be susceptible to issues. Draughts, rattling, sticking or leaks are all common problems.
