Low-E Glass: The Future of Glass

May 30, 2025 | Blog

The type of glass we use in our homes can make a world of difference in our comfort, as well as offering a variety of other benefits. But when there are so many options to choose from, how can you be sure you’re picking the right kind?

Low-E glass utilises innovative technology to help protect your home and boost energy efficiency. In this article, we’ll reveal what makes low-emissivity glass different and why it’s the right choice for new homes.

Understanding Low-Emissivity Glass

Low-emissivity glass refers to an additional coating that can be applied to single or double-glazed glass. This coating is a clear metallic substance that helps to block the transfer of heat or cold through the glass.

Essentially, it works as additional insulation for the home, protecting it from extreme temperatures and heat loss. While it helps to reflect and insulate against solar energy, it is designed to allow light to pass through, so you can enjoy natural lighting without any of the drawbacks.

Types of Low-E Glass

The Types of Low-E Glass

There are two different types of Low-E glass: passive coatings and solar-control coatings. These are each designed to focus on insulating against one kind of heating and solar energy.

While they can both offer general insulation benefits, a passive coating allows more solar heat to enter the home, while solar-control coatings do the opposite.

This is so that you can tailor your glass to suit your home’s needs. If you live in a hotter climate, you will likely prefer solar-control Low-E glass to reduce your need for air conditioning. Meanwhile, colder climates may prefer passive Low-E glass to encourage more heat to enter the home.

Hard and Soft

There are also two different ways of applying the Low-E coating to glass, resulting in either a ‘hard’ or ‘soft’ finish. A hard coating is created when molten metal is applied to the glass during manufacturing. Because both elements are heated, they become welded together, creating a stronger or ‘hard’ bond.

A soft coating is when the coating is applied at room temperature, so the bond is not as closely fused. However, to ensure the longevity of soft coatings, they are often enclosed in double-glazed units. This can ensure you get the insulating benefits of both Low-E and double-glazed glass.

Benefits of Low-E Glass

Low-emissivity glass has been used in various homes and buildings since the 1980s. It is an incredibly popular choice for windows, glass doors, skylights and more because of its sophisticated design and benefits.

Here, we’ll outline the main reasons Low-E glass stands out as an ideal choice.

1. Insulation

By helping to reduce the transmission of heat and cold, Low-E glass works to maintain an ideal temperature in your home. It can prevent heat from escaping, so you can stay warm throughout the year. Likewise, it can reflect heat away from your home during the height of summer, allowing you to enjoy cooler rooms.

2. Energy Efficiency

Low-E glass is a great way to put energy efficiency first. Its ability to insulate the home can help reduce the energy usage needed for heating and cooling.

Likewise, with strategically placed windows, you can enjoy plenty of natural lighting, further reducing electricity costs. Not only is this better for the environment, but it can also significantly impact your hip pocket and reduce future expenses.

3. UV Protection

The Low-emissivity coating reflects UV rays. This can help you protect the interior of your home and furniture from the sun. This way, you can enjoy natural lighting without worrying about potential fading or damage.

Finding a Provider

Low-E glass uses innovative technology to reduce the transmission of UV rays and other forms of heat and cold. However, it must be made with a high attention to detail and care to ensure it works properly. This is why choosing a reliable Low-E glass provider is crucial.

When looking for providers, carefully check what types of glass they regularly install. Likewise, assess how long they have been providing support. It’s essential that your provider has more than a few years of experience to ensure they handle your glass correctly.
