Sash windows are designed to let air in at several points, but by fitting the correct seals at the correct places, you can really tell the difference in terms of warmth and comfort.
Where the Draughts Get In
The Draughts Enter Through Several Places Around the Sashes and Top and Bottom of the Window, as Well as Through the Meeting Rail in the Middle of the Window.
Pile Seals Along the Sides
Pile Seals Along the Sides of Sash Windows – Brush Seals for Sash Windows Pile Seals (often referred to as brush seals) are fine fibres, pressed into a channel (a groove) cut into the staff bead of the sash window. This type of seal runs the entire length of the sash window and is perfect for sealing the gap between the sashes as they travel up and down. The brush seal does not impede the movement of the sashes, and is therefore a fantastic option for sealing draughts in sash windows.
Sealing the Meeting Rail
This is often the worst place for draughts to enter, particularly horizontal meeting rails in the middle of sashes. A good quality compression seal is fitted to this area, which will shut the gap between the two sashes when closed. As confirmed by the Energy Saving Trust this can make a significant difference to the warmth of a home.
What a Professional Job Involves
Sash window repair and draught-proofing can go hand in hand as many windows require joints and sections of timber to be repaired prior to having seals fitted.

Done properly, the sashes should then open and close freely, but be much tighter against the air.
