Official Government figures from 2022 said around 88% of homes in England had double glazing. That was an impressive increase from a decade earlier when it was just 79%. It’s likely the total is even higher now. But, what about properties that can’t have double glazing? The best option here is to look at alternative solutions like secondary glazing. It can provide a big improvement over single pane windows. Let’s have a closer look, then you can talk to us if you want to arrange sash window restoration in Northumberland.

Why do some properties still have single glazing?

There are a few different reasons why a number of homes only have single pane windows. In some cases the property owners simply don’t want to pay to upgrade. More notably though, there are a number of situations where there are actually restrictions. This can include properties in conservation areas and Listed buildings. Here, the owner must get permission before they can upgrade the windows. In some cases this can be unlikely because the original single pane windows have significant heritage value.

What is secondary glazing?

As we said, the best solution if you want to improve the performance of single pane windows is to use secondary glazing. It adds a second layer of material, sometimes film, sometimes glass. The goal is to create a pocket of air to improve insulation, a similar philosophy as double glazing.

The most crucial thing with secondary glazing is it does not have an impact on the aesthetics of the windows. In fact, from the outside they won’t look any different at all. That is crucial when you need to retain the character. Talk to us about sash window restoration in Northumberland.

Does it work?

It’s natural to wonder if simply adding a film or another pane of glass will actually help. However, it’s proven to work. Whichever option you choose, the results can be noticeable, especially during the coldest parts of the year.

When you get secondary glazing, you’ll see an increase in the general temperature within the room. This happens because you’re making it harder for heat to escape through the glass. Even increasing the temperature by a few degrees and slowing the rate of heat loss can make a big difference. It can save energy bills and make the home more comfortable.

Another thing you’re likely to see is less condensation on windows. Single glazing is notorious for misting. One side can get extremely cold because of the external temperature. The other side will be warm because of air inside the property. As a result, you get the perfect conditions for moisture to condense on the glass.

Interestingly, secondary glazing can also provide a noteworthy additional benefit; it can block more external noise. Anybody with single glazing will likely be familiar with how easily noises from outside get into their home. Adding to the windows, whether it is film or glass, can make it quieter.
