How does double glazing prevent heat loss?

31 January 2022

When it comes to improving your home’s energy efficiency, installing double glazed windows is one of the best things you can do. Not only do they look great, but they also help to prevent heat loss in the winter and keep your home cooler in the summer. But how does double glazing work? And what is the science behind insulated windows? This blog post will take a closer look at how double glazing prevents heat loss and why it is such an effective insulation material.

The air between the two panes of glass in a double glazed window acts as an insulator, preventing heat from escaping. In the winter, this trapped air helps to keep your home warm and cosy. And in the summer, it helps to keep the sun’s heat out, preventing your home from becoming too hot.

In addition to the air between the panes, double glazed windows also have a high R-value, which measures a material’s ability to resist heat flow. The higher the R-value, the better the insulation. Double glazed windows typically have an R-value of around R-11, which is much higher than the R-value of a single pane window.

Double glazing also reduces the need for window treatments like curtains or blinds; however, using these in conjunction can improve your home’s energy efficiency.

If you are looking to improve your home’s insulation, installing double glazed windows is a great way to do it. Not only will you see a noticeable difference in terms of comfort and energy savings, but you will also be doing your part to help reduce greenhouse gas emissions and fight climate change.
