Gapseal Sash Window Insulation by Draughtex
Gapseal sash window insulation is a proven gap filler, designed to eliminate the cold draughts and improve the comfort and energy efficiency of your home.
The total gap length around a sash window can reach up to 4m in length and has an average gap width of about 2mm. This is the equivalent of a hole the size of a down pipe being drilled through your wall.
Stopping cold air from being drawn into a room and preventing heat loss will reduce your energy bill markedly and make your rooms more comfortable. Easy to install with the free applicator
