Issues with Single Glazed Windows

Properties with single glazed windows normally suffer from insulation issues and higher energy bills, but there’s a solution to this and that is reglazing. Upgrading your single glazed windows will rejuvenate your home and help you make the most of your existing windows. This doesn’t make cleaning them any more difficult to clean, but if there are any that you can’t comfortably and safely get to, contact a window cleaning service and they will be able to take care of this for you.

What is a single glazed window U-value?

U-values are important when it comes to windows as it measures the rate of heat loss; a higher value indicates poor insulation, meaning heat you’ve paid for is escaping. This is a clear sign that reglazing might need to be considered to improve the energy efficiency in your home.

A single glazed window typically has a U-value ranging from 5.8 to 6.0 W/m²K which is far higher than double or triple glazed windows which prevent heat loss far better. However, with older windows or sash windows, it may not be possible to add double glazing which is where a professional can assist and advise on options such as vacuum glazing and getting Enhanced Comfort with Secondary Glazing.
