Stop the Draughts. Not the Window  Double-hung windows need room to slide - which is exactly why they can be so draughty. Air leaks around the sides and bottom of the lower sash, as well as through the centre join between the two panes.

This kit uses self adhesive fixed brush seals along the sides and bottom of the window. The sash slides past the brushes, so you can still open and close it normally. A slim EMV-seal closes the remaining gap where the upper and lower sashes meet.
