Sash Window Draught Proofing

Draught proofing your sash and casement timber windows will have a dramatic effect on the thermal efficiency of your home, removing draughts and reducing noise.


We fully recommend the installation of draught proofing to all our London, Hertfordshire, Essex and Middlesex customers’ sash and timber casement windows to eliminate draughts and reduce noise, while not effecting the traditional look of the windows.

Once installed, draught proofing your timber windows will not only have a dramatic effect on the thermal efficiency of your home, but your sash window will function with ease, moving smoothly and quietly…no more jams or rattles!

With any restoration or repair work, where sash windows are removed, we thoroughly suggest installing draught proofing at this point, maximising on improvements to the window whilst they are removed.

With any restored and refurbished sash windows from London & Herts Sash Windows, draught proofing will be fitted as standard.
