Yes, replacing misted or blown double glazing can make a noticeable difference to your heating costs. When a sealed unit fails, it no longer insulates properly, allowing heat to escape and cold air to enter your home.
Modern replacement glass is manufactured to high thermal standards and provides a much better U-value than failed units. This means your home retains heat more efficiently, reducing the need to keep your heating on for longer periods.
By replacing only the glass and keeping the existing frames, you get improved energy efficiency without the high cost of full window replacement. It’s a cost-effective way to make your home warmer and more energy efficient.
