What Is ‘Low-E’ Double Glazing?

If you’ve been shopping around for new windows online, you’ve almost certainly encountered the phrase “low-E glazing.” Home improvement websites often include it as an optional upgrade, but what exactly is it? And is it worth investing in?Here at Ecostar, we’ve been singing the praises of double glazed windows for a long time. Regular double glazing is an excellent choice, but if you want to really knock it up a notch, it’s worth choosing low-E windows. Why? Here’s why.

Low-E Glass Explained

Low-emissivity glass, or low-E as it’s widely known, is a relatively new invention. It’s a type of glass that’s had a thin, transparent coating applied which reflects infrared and ultraviolet light back into the outside world. Despite being thinner than human hair, this coating is remarkably effective. It helps keep the home’s interior temperature consistent by minimising heat transfer, all while still letting in plenty of sunlight. 

To put it simply, low-E glass takes all the energy benefits of regular double glazed windows but raises them to the next level. Low-E windows have better U-Values and are ideal for reducing your energy consumption. We have an unpredictable climate here in Australia, but when you can manage household temperatures easily, you’ll need to use the air conditioning and heating a lot less. Your bills will drop, along with your carbon footprint. This is a major benefit of all double glazed windows, but low-E ones are even better. 

The other advantage of low-E windows is that they protect your furnishings. By blocking UV rays, they reduce the risk of furniture colours fading. Got a favourite armchair that you want to keep looking its best? Swap your nearby windows for low-E ones and it will retain its colour for years. 

Are Low-E Windows Worth It?

In brief, yes. Low-E windows are well worth investing in, but here’s the thing. Remember in the opening paragraph where we said that most places include it as an optional extra? At Ecostar we don’t do that. We provide low-emissivity glazing as standard in all of our windows.
