When it comes to double glazing, there is a lot to know and understand. Regular questions can arise on how to gauge the quality of the windows, how it’ll affect your energy bills and whether or not it will result in an increase in your property’s value.

So you have a better understanding when you come to invest in them, here are six frequently asked questions to do with double glazing and their answers:

What is double glazing?

Double glazing refers to a window or door that’s made up of two panes of glass, which have a space between them containing air or gas. This trapped air or gas works as an insulator, keeping heat inside, as well as strengthening the window.

This is different to a standard window which is made of just one pane. There is no trapped air to work as an insulator, meaning it’s far easier for heat to escape.

How do I find out how energy efficient a window is?

New windows now come with an energy efficiency rating from A to G. A is the best and G is the lowest rating.

Anything above C is considered to be ‘good’, but over the years more money can be saved by investing in a more efficient window.

How much money can be saved?

This all depends on what double glazed windows you decide to go for and their energy efficiency rating, as well as your house size and how you use the heating.

As an average, a property can expect to save around £200 when switching from old single glazed windows to at least B rated double glazing.

Would double glazing ruin the appearance of an older property?

There is some debate over whether double glazing would alter the rustic appearance of an older house.

While it’s completely subjective, people will often choose to go with double glazing regardless of whether it’d affect the character or appearance of the building. The added security and better energy efficiency is enough to show people how useful double glazing can be for their home.

However, today you can get double glazing that’s designed to complement the features of a period property. This may cost more initially but is well worth it in the long term if you want to ensure you retain your property’s style and charm.

How would it affect the property value?

This all depends on what type of window you go for. Single glazing has been proven to have a negative effect on whether people buy a property or not in the same way that cheap, low quality double glazing has.

Prospective buyers see single glazing and low quality double glazing as something that they’d need to replace – meaning more costs for them. While double glazing wouldn’t necessarily add more money on to your property, it certainly can make your property much more attractive than if it was without.

How would a listed property get double glazing?

It can be hard work or even impossible for listed property owners to be allowed to fit double glazing on their property. In that instance, secondary glazing is available.

Secondary double glazing involves installing a second pane of glass over the first. Although it doesn’t work as well as full double glazing, it is a good compromise if rules and regulations prevent you from installing real double glazing.
