Is DIY Draught-Proofing Possible for Sash Windows?
Many homeowners wonder if they can tackle draught-proofing sash windows on their own. The answer is a resounding yes. With the right tools and a bit of patience, DIY draught-proofing can be both achievable and cost-effective. Start by inspecting your windows for gaps and cracks.
Once identified, these areas can be sealed with specialized draught-proofing materials readily available at hardware stores. Simple yet efficient, this method empowers homeowners to take control of their home’s insulation without breaking the bank.
Using Silicone: Is It Effective for Draught-Proofing Windows?
Silicone sealant is a popular choice for draught-proofing windows. Its flexibility and durability make it ideal for filling gaps and cracks around sash windows. Applying silicone along the window frames creates a tight seal, preventing cold air from seeping in. This method offers a relatively quick and easy solution, ensuring a snug fit that keeps your home warm and draught-free.

Effectiveness of Adhesive Draught Strips on Sash Windows
Adhesive draught strips are another practical option for sash window draught-proofing. These strips, made from materials like rubber or foam, can be easily attached to the window frames. When the window is closed, the strips compress, forming a seal that blocks out draughts.
This method is especially useful for older windows that may have irregular shapes or gaps. Adhesive draught strips are affordable, readily available, and simple to install, making them a popular choice among homeowners looking for effective draught-proofing solutions.

Brush Seals: A Reliable Method for Draught-Proofing Sash Windows?
Brush seals, also known as pile or bristle strips, are excellent for draught-proofing sash windows while allowing for smooth operation. These seals consist of densely packed bristles that create a barrier against draughts when the window is closed.
Brush seals effectively block cold air, dust, and noise, enhancing both comfort and energy efficiency in your home. They are durable and long-lasting, making them a reliable choice for those seeking a lasting solution to window draughts.
Temporary Solutions to Prevent Draughts: What Works?
While long-term solutions are essential, there are also temporary methods to prevent draughts, especially during extreme weather conditions. One such method is using draft stoppers or door snakes. These fabric tubes filled with insulating material can be placed along the bottom of the window, creating a barrier against cold air.
Additionally, heavy curtains or thermal blinds can be hung to provide an extra layer of insulation, minimizing draughts and maintaining a warmer indoor environment.
Professional Techniques for Efficient Sash Window Draught-Proofing
For homeowners seeking a comprehensive and tailored approach to draught-proofing, professional services offer specialized techniques. One such method is the installation of secondary glazing. This involves fitting an additional pane of glass or acrylic to the existing window frame, creating an insulating barrier that significantly reduces heat loss and draughts.
Sash Window Refurbish also often include a thorough inspection of the window frames and sashes to identify and seal any gaps effectively. These professionals use high-quality materials and tools to ensure a precise and long-lasting draught-proofing solution tailored to your home’s specific needs.
What sash window draught-proofing kit includes?
A typical sash window draught-proofing kit includes:
- Draught-proofing strips: These are usually made of rubber, silicone, or brush pile and are installed around the edges of the sash window frames. They effectively seal the gaps between the window frames, preventing cold air from entering and warm air from escaping.
- Sealant: This is used to fill larger gaps or cracks in the window frames. It ensures a tight seal and helps in reducing drafts.
- Beads and carriers: These are components that hold the draught-proofing strips in place. Beads are often installed on the window sashes, while carriers are fixed to the window frames.
- Brush strips: These are attached to the meeting rails (where the two window panels meet) to prevent drafts from entering through the top and bottom of the window.
- Fixing screws/nails: These are used to secure the draught-proofing strips, beads, carriers, and brush strips in place.
Proper installation of these materials can also help in reducing noise pollution and enhance overall insulation in the house.

Costs of Draught-Proofing
The choice of your approach will determine the expenses incurred for sealing your sash windows against drafts.
Self-adhesive weatherstrips are priced at approximately £5-£6 for a 5-meter roll, whereas self-adhesive brush pile carriers, measuring 2.2 meters, can be obtained for as low as £1.40.
As per the Energy Saving Trust, a comprehensive professional draught proofing service for your entire house could amount to approximately £225. (This estimation is based on a standard semi-detached property in England, Scotland, or Wales.)
FAQs
What is the best draft proofing for sash windows?
The best draft proofing for sash windows typically involves using weatherstripping and draught excluders. These can be installed around the window frame and sashes to prevent cold air from entering and warm air from escaping.
Are sash windows draughty?
Traditional sash windows, especially older ones, are often prone to drafts due to their design and ageing components. Gaps between the sashes and frames can allow drafts to enter, making them draughty without proper maintenance.
Are modern sash windows drafty?
Modern sash windows are designed with better insulation and materials, reducing the likelihood of drafts. However, if not properly installed or sealed, they can still develop drafts over time. Regular maintenance is key to ensuring their efficiency.
