Draught Proofing

Where replacement windows are not an option, our expert draught proofing service can optimise the performance of your existing timber windows.

Suitable for both sash and casement windows, our draught proofing solutions can help to minimise heat loss, reduce outside noise, and prevent dust penetration. Precision matched to your existing windows, our carefully installed draught proofing solution helps to improve the all-round performance of your windows, for exceptional results.


Exclusive to The Original Box Sash Windows Company, the ‘Sashslide’ draught proofing solution uses a combination of hand-crafted timber control strips and precision-applied silicone coating to block draughts, damp air, noise and dust from entering your home from outside.

Fitted by our expert installers, ‘Sashslide’ is a neat and discreet solution that has the added benefit of assisting your sash window to slide more easily than before.

New weights and cords are included in the service if required.


Our ‘Sashseal’ draught proofing solution is designed for casement windows, delivering all the benefits of the ‘Sashslide’ solution to your hinged windows. Using the same, high quality timber and silicone system, ‘Sashseal’ keeps casement windows operating smoothly and improves the performance of your windows while remaining sympathetic to their original character and style.  

Like ‘Sashslide’, ‘Sashseal’ is available in natural timber or your choice of colour finish.
