Draught proofing is one of the most effective ways to improve the comfort, efficiency, and performance of traditional timber sash windows without replacing them. At Matt the Sash, we use proven methods designed specifically for period windows.

 

 

What Is Sash Window Draught Proofing?

 

Sash window draught proofing involves fitting a discreet brush pile system into the existing window sashes and frames. This creates a tight seal that reduces cold air entering the property while still allowing the windows to operate smoothly.The system is carefully installed so it is:

​

• Visually unobtrusive

• Reversible

• Suitable for period and conservation properties

 

 

Benefits of Draught Proofing Sash Windows

 

Properly draught-proofed sash windows can provide:

 

• Reduced heat loss and improved energy efficiency

• Less rattling in windy conditions

• Smoother window operation

• Reduced external noise

• Improved overall comfort throughout the home

 

Many homeowners are surprised at how much difference draught proofing alone can make.

 

 

Our Draught Proofing Process

 

Our process typically includes:

• Careful removal of the sashes

• Inspection of cords, weights, and timber condition

• Installation of a high-quality brush pile draught proofing system

• Rebalancing and refitting the sashes

• Final testing to ensure smooth, quiet operation

•  

Where required, minor repairs can be carried out at the same time.

 

Suitable for Period & Conservation Properties

 

Draught proofing is often the preferred solution for:

• Victorian and Edwardian homes

• Georgian properties

• Conservation areas

• Listed buildings (subject to requirements)

 

Because the original windows are retained, draught proofing is usually acceptable where replacement would not be.
