Draught Proofing for Sash Windows
Enhancing Comfort and Efficiency While Preserving Heritage

What is Draught Proofing?


Draught proofing is a specialised method used to seal unwanted gaps in doors and windows which prevent cold air from entering a home and also prevents the warm air from escaping. This not only improves energy efficiency but also enhances comfort and reduces external noise from busy roads. Draughts can often become a problem due to natural wear and tear of components or minor warping over time. The charm and beauty of original timber sash windows are undeniable, but without proper draught proofing, they can allow considerable heat loss, leading to higher energy bills and a less comfortable home environment.

Draught proofing addresses these issues by creating a barrier against air leakage while preserving the aesthetic and functional qualities of the windows. This is done by using high quality brush pile seals. It is particularly beneficial for period properties, where replacing windows with modern alternatives would diminish the historic character of the building.

Our Draught Proofing Services


At Traditional Sash Windows and Carpentry, we offer comprehensive draught proofing services tailored specifically to suite sash windows and wooden doors. We understand that each property is unique, and every window has its own characteristics, which is why we take a bespoke approach to every project. Our service includes:

  1. Initial Consultation: We start by conducting an in depth survey of your sash windows or doors to identify areas that are suffering from poor insulation. This includes checking for loose glazing, gaps around the frame, or any warped timber that might allow air to pass through.

  2. Quotation: After assessing your windows, we provide a transparent quotation outlining the work required and materials to be used, along with a breakdown of costs.

  3. Professional Draught Proofing Installation: Our team of experienced craftsmen meticulously install draught proofing systems using techniques that are sympathetic to the historic nature of sash windows, ensuring minimal visual impact.

  4. Free Aftercare Visit: Your satisfaction is our priority, which is why we offer a complimentary aftercare visit within 12 months of the installation. We’ll check that everything is functioning perfectly and address any issues that may have arisen completely free of charge.

We can also provide additional services such as sash window restoration, including reglazing and timber repair, to ensure your windows are in the best possible condition.

How We Draught Proof Sash Windows

Our draught proofing process is designed to be thorough yet non invasive, ensuring that your sash windows retain their original beauty and function smoothly. Here’s a detailed step-by-step breakdown of our method:

  1. Careful Removal of Sashes: The first step involves gently removing the sashes from the frame, allowing us to work on them without causing damage to the timber or glass. This is done using traditional methods that protect the structure of the window.

  2. Cleaning and Inspection: Once the sashes are removed, we clean all accessible areas of the window frame and inspect the components for any damage. This includes checking the condition of the sash cords, pulleys, and weights to ensure the window is operating correctly.

  3. Repair and Restoration (if necessary): If we find any defects such as rotting wood or broken sash cords, we carry out repairs using high-quality timber and materials that match the existing window. This is crucial in maintaining the structural integrity of your sash windows.

  4. Fitting of Draught Seals: We install discreet yet effective draught proofing seals around the window frame, parting beads, and staff beads. These seals are typically made from silicone or brush pile and are designed to compress when the window is closed, blocking any gaps that would allow air to pass through.

  5. Sash Reinstallation and Rebalancing: After fitting the draught proofing seals, we carefully reinstall the sashes into the frame. We then re-balance them, adjusting the weights if necessary, to ensure smooth operation and no rattling.

  6. Final Checks and Testing: The last step is to test the window for airtightness and ease of use. We ensure that the draught proofing system is effectively sealing the window while allowing it to open and close effortlessly.

The Materials We Use

We prioritise using materials that are both high-quality and sympathetic to the historical context of your property. For our draught proofing installations, we use:

  • Brush Pile Seals: These are made from durable materials like polypropylene, which provide an effective barrier against draughts while remaining discreet. They are ideal for sealing larger gaps around the window frame and offer excellent thermal performance.

  • Silicone Seals: Silicone seals are perfect for narrow gaps and create an almost invisible seal that does not compromise the window's appearance. They are highly flexible and resistant to weathering, ensuring long-term performance.

  • Timber for Repairs: Any timber used in repairs is sourced to match the original wood as closely as possible, both in grain and appearance. We use sustainable, high-quality timber that enhances the lifespan of your sash windows.

The History of Draught Proofing

The concept of draught proofing has existed since the early days of sash window design, with early homeowners often using rudimentary methods such as fabric strips or paper to block gaps. However, it wasn’t until the 18th and 19th centuries that more advanced techniques began to emerge, as homeowners and architects sought to balance aesthetics with practicality.

In the Victorian era, sash windows became more widespread, and draught proofing techniques evolved to include rubber and leather seals. During the energy crisis of the 1970s, there was a renewed interest in improving the energy efficiency of historic properties, leading to the development of modern draught proofing systems that we use today.

Interesting Facts About Draught Proofing

  • Energy Efficiency Benefits: According to research by the Energy Saving Trust, draught proofing sash windows can save up to £50 per year on heating bills for a typical home in the UK.

  • A Sustainable Solution: By draught proofing your sash windows, you reduce the need for energy intensive heating, lowering your carbon footprint and contributing to a more sustainable future.

  • Improved Property Value: Draught proofing is a cost effective way to enhance your property’s value. Well-maintained, energy efficient sash windows are highly sought after in the property market.

  • Noise Reduction: Draught proofing can also significantly reduce the amount of noise entering your home from busy Kent and London streets, making it ideal for properties located in busy areas or near main roads.
