Sash windows are a timeless feature of many homes, particularly in period properties. However, while they offer charm and elegance, they can often be a source of unwanted draughts, leading to higher energy bills and a less comfortable living environment. Draught-proofing your sash windows is an effective solution that can help you retain the traditional beauty of your windows while significantly improving energy efficiency.
In this blog, we’ll cover why draught proofing is important, how to identify draughty windows, and the methods you can use to seal up your sash windows without compromising their look or function.
Why Draught Proofing is Essential
Draughts can enter through gaps in your sash windows, particularly around the edges where the sashes meet the frame. This can lead to:
Heat Loss: Cold air entering the home, leading to increased energy costs.
Condensation and Damp: Draughts can encourage condensation build-up, leading to dampness that may damage your walls, ceilings, and furnishings.
Reduced Comfort: A draughty room can feel cold and uncomfortable, even with heating.
By draught-proofing your sash windows, you can enjoy a warmer home, reduce energy bills, and lower your carbon footprint - all while preserving the aesthetic value of your property.
Identifying Draughty Sash Windows
Before you start the process, it's essential to assess whether your sash windows need draught proofing. Here are some common signs:
Cold Spots: If you feel cold spots near your windows, especially during windy days, there’s likely a draught.
Rattling Windows: Sash windows that rattle when closed often have gaps allowing air to flow in.
Visible Gaps: Inspect the area where the sashes meet the window frame. Even small gaps can let in cold air.
Methods for Draught Proofing Your Sash Windows
Draught-proofing a sash window doesn't mean completely sealing it shut. It involves carefully sealing the gaps around the moving parts while allowing the window to open and close smoothly. Below are some methods to consider:
1. Brush Strips
Brush strips are an affordable and effective way to seal the gaps around sash windows. These flexible strips are designed to slot into the window frame and block draughts without obstructing the movement of the sashes.
2. Foam Strips
Self-adhesive foam strips are another simple solution. They can be applied along the edges of the window frame to prevent air from entering through gaps. While foam strips are cost-effective and easy to install, they may need to be replaced more frequently than other materials due to wear and tear.
3. Draught Seals (Weatherstripping)
Professionally installed draught seals are a more durable and long-term option. These seals are fitted around the window frame and sliding sashes, creating an airtight barrier while allowing smooth movement. Draught seals are discreet and can significantly reduce draughts.
4. Secondary Glazing
For maximum insulation, secondary glazing is an excellent option. This involves installing an additional pane of glass on the inside of your sash window. While more expensive than other methods, secondary glazing not only reduces draughts but also improves soundproofing and energy efficiency.
5. Caulking
Caulking around the exterior of the sash window can help prevent draughts. Over time, the caulking may crack or peel, allowing air to enter. Re-caulking these areas ensures that there are no gaps where cold air can sneak in.
6. Sash Window Repair
If your sash windows are old or damaged, it may be worth repairing them before draught proofing. Warped or broken sashes can create significant gaps that allow draughts in. A professional sash window repair can restore the original function of your windows and prepare them for effective draught proofing.
Benefits of Draught Proofing Your Sash Windows
Lower Energy Bills: By reducing heat loss, draughtproofing can help cut your energy consumption, leading to lower heating bills.
Increased Comfort: With draughts blocked out, your home will feel warmer and more comfortable, even in colder months.
Preservation of Your Windows: Draught proofing ensures that your sash windows remain functional and attractive without needing to be replaced.
Eco-Friendly: Less heat loss means less energy is required to heat your home, which reduces your carbon footprint.
Improved Soundproofing: Draughtproofing can also reduce noise from outside, making your home more peaceful.
Professional Draught Proofing vs. DIY
While some draught proofing methods, such as foam strips and caulking, can be tackled as a DIY project, others, like brush strips and secondary glazing, are best left to professionals. A specialist can ensure that your sash windows are correctly sealed without compromising their movement or appearance.
Draught-proofing your sash windows is a practical way to maintain the beauty of your home while improving its energy efficiency. With several options available, from brush strips to secondary glazing, you can choose the solution that best suits your needs and budget.
