Sash Windows: A Smart Investment for Your Home’s Energy Efficiency

Updated: 5 days ago

As a sash window expert, I often get asked about the benefits of installing these beautiful windows in homes across the UK. Sash windows offer charm and character, but they also provide some excellent practical benefits that can save money and increase your home’s value. In this post, I’ll break down the top reasons to choose sash windows if you’re considering new windows for your home.


Improved Energy Efficiency And Reduced Energy Bills


One of the best reasons to select sash windows is that they can significantly improve your home’s energy efficiency when double or triple-glazed. According to research by the Energy Saving Trust:


  • Homeowners can save £195 annually by installing A-rated double-glazed windows in a single-glazed semi-detached home.

  • With A++ rated double-glazed sash windows, savings can reach £235 annually.


These energy savings are thanks to the insulated air space between the glass panes found in double and triple glazing. This insulative layer slows heat transfer, reducing convection and conduction through the window. Your home retains warmth for longer, lowering your heating costs.

When assessing a window’s energy efficiency, I look at its U-value or thermal transmittance. The lower the U-value, the less heat is lost through the window. Sash windows with double or triple glazing provide excellent U-values.


Reduced Noise Pollution


Double-glazed sash windows reduce noise, while triple-glazing is even more effective at blocking external noise pollution. If you live on a busy road or under a flight path, new sash windows with triple glazing can make a big difference to the noise level entering your home.


Enhanced Strength, Durability, And Security


Sash windows require more robust window frames to accommodate double or triple-glazed units. The added strength improves the windows’ overall durability and security. Your new sash windows are built to last for decades while protecting your home.


Less Condensation


By installing new double or triple-glazed sash windows, you can minimize the amount of condensation that forms on the inside of the glass. This helps reduce damp and mould growth in your home.


Added Property Value


Improving your home with new double or triple-glazed sash windows can increase your property’s value when it comes time to sell. Many prospective buyers look for at least double-glazed windows so that this upgrade can maximize your home’s resale value.


In summary, sash windows aren’t just beautiful – they offer many functional benefits too. If you’re considering new windows for your UK home, explore the advantages of double or triple-glazed sash windows. Proper installation can save you money on energy bills, reduce noise, enhance security, minimize condensation issues, and add value to your property.
