Draught Proofing Sash and Case Windows – What is it and why?
First we have to consider the design of Sash and Case windows and the effects of opening and closing over the years, decades or even centuries. It’s likely the windows were originally a tight fit that glided easily but with wear and tear and paint build up you can understand why they might have gaps and lumps etc. in the woodwork. The smoothness of the surfaces is important for clean operation of the windows.
The second area of consideration is modern living and the impact of central heating and how that can affect the operation of a Sash and Case Window. Our expectations of modern living and how we expect windows to seamlessly open and close, whilst expecting ventilation one minute and air tight the next has changed over the years. The variations of temperature inside and outside have an impact on the wood itself through contraction and expansion. Fractions of centimetres will make a difference regarding the smooth operation of the Sash and Case Window.
The third area of consideration when it comes to draught proofing Sash and Case Windows is the requirement to let the room breathe as without this some rooms could be susceptible to condensation and damp. Draught proofing must strike that balance of providing an operational and efficient window without compromising the living space and not detract from the window itself, i.e. hidden when observing the window either from inside or outside.
Draught proofing Sash and Case Windows is achieved by a skilled carpenter who will address the operational efficiency by stripping back years of paint and ensuring the windows are working properly. This may involve replacing the chords and pulleys to ensure efficient slide. The installation of the draught proofing is achieved by cutting a groove out of the top rail of the upper sash and the bottom rail of the lower sash. A weatherproof and hardwearing brush system is installed into both grooves so they meet when the windows are closed and the baton rods and parting beads are replaced with new timbers that have the integrated brush system. The draught proofing is discreet and hidden when looking at the window but highly effective in terms of draught proofing the Sash and Case Window.
