4 Ways To Eliminate Sash Window Draughts

Sash Windows offer a beautiful finish to any historical building; but like all things in life, they will deteriorate due to not being treated, damaged or through sheer age. This deterioration takes the form of gaps that are created in the frame, regularly producing a ‘rattling’ sound. This indicates that the window is loose and is open to further elements – such as weather, noise, even dirt and debris from infiltrating your home. Another aspect, is the filtration of energy from inside of your home, to the outside. This will leave you cold, uncomfortable and paying a high heating bill for heat that you’ve not used.

Here at Kellys Sash Windows, we have a long experience in installing, fixing and restoring elegant sash windows in a wide range of properties.

Eliminating Sash Window Draughts


If a gap appears around a sash window fitting, it has the potential to create a hole that could be sized at around 6 inches – so it’s easy to see how easily elements from the outside can get inside a deteriorating window fitting. There a number of ways in which to treat or prevent draughts from entering your home.


Here are 4 ways in which sash windows are able to keep out draughts:

  • Draught Proofing. Offering the cheapest and quickest way in which to keep out elements from the outside, draught proofing is done by blocking and covering the holes that exist in the window fittings, preventing cold air from coming in and warm air from escaping. Whilst this is a good way to prevent draughts in the short term, it may need doing on a regular basis in order to maintain its effectiveness over a longer period of time.


  • Replacing Single Glazed Windows. Also known as insulated glazing, double glazing is the practice of placing two panes of glass into a window frame, which offers the home better protection from the elements outside. Whilst it’s possible for these elements to infiltrate one pane of glass, the space that exists between the two will stop them before they get through to the second pane, which is why double glazing is much better at insulating heat and reducing noise from the outside.


  • Replacing Older Types of Glazing. Although double-glazing is pretty-much commonplace nowadays, changes in technology and regulations mean that new types of double glazing better retain the environment in the home, than older, thinner double glazing. In cases like these, replacing your old double glazing would help to further reduce heat loss, as well as draughts.


  • Restoring the window fitting. Offering a cost-effective way in which to improve a deteriorated window frame, restoring a fitting will help to repair its faults as well as maintain its classic look.


  • Replacing the entire window fitting. Whether it’s due to the sheer deterioration or a purely aesthetic choice, replacing the entire fitting offers a complete solution in reducing draughts that emanate through a sash window. By replacing the entire fitting – either with a more-modern uPVC fitting or a more-traditional timber fitting – you will be putting in place a long-term solution to the many issues that affect such a classic property. Aside from the benefits of no draughts and savings made on energy bills – many homeowners with modern fittings have seen the value of their property rise. Over time, the investment in replacing the window fittings will pay for itself – showing why it’s a popular method for many.


Types of Sash Window Frames.

If you’ve decided to replace your existing window fittings, there are two main types of materials that you can use to create a new one with. Here at Kellys Sash Windows, we offer two types of frame; timber and uPVC.


  • Timber fittings – Classically used in traditional sash window installations, brand-new timber fittings are designed to retain the natural character of a property. Well-made, high-quality timber fittings are able to last for a very long time if regularly treated and provide a durable, hardwearing solution in preventing draughts and insulating heat.


  • uPVC fittings – Offering a modern solution to draught issues, uPVC (also known as PVCu) have been custom-made to contribute to the insulation of the home, be friendlier to the environment and unlike timber fittings, won’t need any regular maintenance which will save time, effort and cost in the long term.
