DIY draught proofing

According to the Energy Saving Trust 18% of heat loss in the home is through windows, so by fitting draught proofing you will not only feel more comfortable but you will also save money.

An average window or door will cost around £10 to draught proof if you install the products yourself.

Watch our step by step video on how to draught proof doors and sash windows:

To draught proof your doors and sash windows you will need:

  • A Tape Measure
  • A Junior Hacksaw
  • A hammer
  • A nail punch
  • A pair of wire cutters
  • A Bradawl or drill – for making additional holes in the strips
  • Masking tape can also be useful to hold strips in place

Tip: A thick stiff piece of cardboard can be a useful aid to protect windows when hammering

Where can I buy the draught proofing materials?

The Energy Advice Team based at 222 Upper Street stock the materials used in the video as well as other energy saving items. See our full range of products here

  • Q Lon SBS - For the vertical sides of the window frame
  • Q Lon FS - For the point where the sashes meet
  • Q Lon 21L - External door draught strip
