Sash Window Draught Proofing

This is recognised by HMRC as being a ‘significant energy saving measure’ which enables us to charge VAT at the reduced rate of 5%.

For a fraction of the cost of replacement windows we can thoroughly service and draught-proof your windows as detailed below and providing these benefits:

Sash Window Draught Proofing

A New Two-piece Parting Bead (1)

  • U shaped section screwed into original parting bead groove.
  • Detachable pile carrier snapped into U section to allow removal of sashes.
  • Height of draught-proofing pile selected to eliminate air infiltration and allow low friction sliding

Mid & Bottom Rail (2 and 4)

  • Grooves routed to sash mid rail and bottom rail.
  • Pile carriers installed.
  • Draught-proofing pile (weatherstripping) is selected to suit varying widths of gaps.

Staff Bead (3)

  • Existing staff bead replaced by new staff bead incorporating the draught-proofing pile.
  • Painted with acrylic white primer conforming to BS 5082.
  • Fitted with brass screws for easy release.

Note 1) – All Weatherstripping is selected to suit varying widths of gaps. It meets all requirements of BS 7386 Specification for Draughtstrips for draught control of existing doors and windows in housing. It is also silicone treated to repel water and is ultra violet stabilised.

Note 2) – The windows will be left easily removable from the new, high quality sash cords.

The sashes will be left perfectly counter-weighted and any extra lead required for this will be supplied free of charge.

Listed Buildings & Conservation Areas

A draught-proofing system such as ours is automatically approved and often suggested by Conservation Officers as it does not ‘alter the character’ of the window.

Please see what Cheltenham Conservation have to say about draught-proofing on p.9 of their document: ‘The Conservation and renewal of timber windows’

However, if you live in a listed building or in a conservation area you should contact your Conservation Officer for specific advice if you plan to change the character of your property. This would include replacing your windows.
