Sealing

The gaps between sash frame are the primary cause of draughts. They can also lead to noise reduction and rattle. Sealing beads, specialty products, and secondary double glazing Spalding may all be used to reduce the air leakage in a sash.

A gap between the top and Double Glazing Potters Bar bottom of the sash, and the jamb frame, is a common problem. This could cause moisture to leak in, rotting wood and the growth of mold. Seal the gap using silicone, polyurethane or foam sealant.

Installing a new sash runner or spring bronze could be required in the event that a gap blocks the windows from closing and opening smoothly. These bronze strips are tied or stapled to the lower sash edges in order to stop the rattling of the sides. They can be bought at DIY stores. Tubular vinyl weatherstripping can also 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.

These measurements can then be transferred to new runners, which will ensure a better fit and operation of the window.

In older structures the gap between the frame and sash is typically greater around the leading edge. It is possible to draught proof by using a self-adhesive V-strips, but it is crucial to take this into consideration when cutting and measuring the material.

The strip should be cut at the height of the sash and with an inch more on each side to allow movement. It should be trimmed square and placed so that the ends are aligned to the angle of the window sill. Use stainless steel screws since brass may rust. Also, make sure to use a high quality silicone or polyurethane glue.

Refurbishment

The sash stops must be removed, a thin vertical strip of wood that is used to hold the sash. Also, remove any painted-covered hardware. Reverse the sash to reveal the weight. It is a heavy iron or lead cylinder, which is tucked away in a cavity and is supported by a cord. To stop the sash from falling into the void pierce it using a nail, and then let the weight go.
