Sealing

Sash windows can look stunning in older buildings, but they require maintenance and are susceptible to problems like wet rot, cracked putty and drafts. It is possible to reduce energy loss and increase the efficiency of sash windows by replacing the windows, repairing or sealing them.


Draughts are mainly caused by gaps between the sash and the frame. They can also cause noise and rattling, which can reduce soundproofing. Sealing beads, specialty products, and secondary glazing may be used to limit the air leakage in the shutter.

A common issue 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 result in the leaking of moisture and rotting of the wood and growth of mould. Seal the gaps with silicone, polyurethane, or foam sealant.

Installing a new sash runner, or spring bronze might be required when a gap is preventing windows from closing and opening easily. These strips of bronze are attached by staples or nails 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, however it is more likely to tear and may alter the look of your window.

It is recommended to take measurements from the top of sash up to the horizontal centerline of the rail of the meeting and from the bottom sash down to the sill. These measurements can be transferred to the new runners, which will ensure a perfect fitting 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 can be draught proofed by a self-adhesive V-strip, but it is important to consider this when cutting and measuring the material.

A strip must be cut to the height of the sash, with an additional inch each side to allow to allow movement. It should be trimmed square and positioned in a way that the ends are matched to the angle of the window sill. It is also essential to use stainless steel screws, since brass can rust and a high-quality polyurethane or silicone adhesive.

Refurbishment

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). Finally, it's recommended to fit brush pile weather strips in order to minimize rattle and increase insulation.

Unscrew the sash stops (a thin vertical strip of wood that supports the sash) and remove any paint-encrusted hardware. Reverse the sash to reveal the weight. It is a heavy iron or lead cylinder, which is tucked away in a cavity, and held by an elastic cord. To prevent the sash from falling into the void pierce it with nails and remove the weight.

After the sashes have been removed clean the jamb and meet rails. remove the glazing bars and sash cords, and remove any paint off the sash stops with an utility knife. Reattach the stops once the sashes have been reinstalled. Use nails that are not large enough to puncture the balancing weight.
