Do you ever walk by your Windows in the winter and notice a draft in the area? Are your heating bills higher than you want, and do you feel you can’t keep your house warm? Do you fight to keep things cool during the summer, when you can feel the heat from the sun blazing through your windows? Let us look at how Double Glazed Windows improve indoor temperature.

If any of this sounds familiar, you may want to consider getting double-glazed windows. Read on to learn more about how double-glazed windows work and discover the benefits they can bring to your home.

How Heat Travels

Before we get into the science of how double-glazed windows work. We need to know how heat gets into and out of your house. Heat travels through your exterior walls through two primary processes: radiant heat and heat loss.

Heat loss happens when heat seeps through cracks around doors and windows and into a colder space. For instance, if you walk by a door and feel a draft in the winter, you feel heat loss in action.

Radiant heat comes from the warmth of the sun shining through glass. When your pet takes a nap in the sunny spot on the rug, they enjoy the benefits of radiant heat.

What Are Double-Glazed Windows?

Now that we know more about how heat travels, what are double-glazed windows, and how do they stop heat transfer? In simplest terms, a double-glazed window has two layers of glass instead of one. A small space separates these layers – usually between 12 and 16 mm.

However, the space between these two panes of glass isn’t filled with normal air. This space is vacuum-sealed and is usually filled with a non-conductive gas, such as argon or krypton gas. As we’ll discuss later, these gases help slow heat transfer even more and make your home more comfortable.

Extra Pane of Glass

The first line of defence double-glazed windows offer against heat transfer is an additional pane of glass. Even single-pane windows stop much heat from moving into or out of your house. Adding another pane reduces heat loss even before we discuss other measures here.

Vacuum-Sealed Chamber

One of the biggest factors in double-glazed window insulation is the vacuum-sealed chamber between the panes of glass. As you likely know, heat moves through normal air very easily. Although we can’t see it, our air comprises many tiny molecules, jostling and bumping together, exchanging electrons and letting heat flow.

By vacuum-sealing the gap between the two panes of glass, window manufacturers reduce the number of molecules floating around in that space. It’s much harder for heat to pass through the resulting vacuum because there are relatively few molecules to hitch a ride on. And by filling that space with argon or krypton gas, which don’t easily share electrons, they can still improve that heat resistance.

Improved Frame Construction

Although it often gets overlooked, many double-glazed windows make their frame construction much more efficient. Single-pane windows, especially those manufactured today, are very cheap and cheaply made. They use materials that don’t do much to prevent heat transfer and are more likely to have gaps and cracks that let heat through.

Because double-glazed windows are a little more high-end, they’re made with better materials and more care. The frames are constructed with materials and coatings that resist heat loss and radiant heat transfer. And they’re built to fit together snugly, ensuring you don’t have any gaps for heat to leak through.

Reflective Coating

In addition to the visible light spectrum – light and colours, we can see – the sun emits invisible light rays, including infrared and ultraviolet. These rays can bleed through normal glass, just like visible light, heating our homes and damaging our belongings. Double-glazed windows often have a reflective coating on the glass, which helps them resist heat transfer.

Some manufacturers put a protective coating on the glass in their double-glazed windows. This coating helps to reflect infrared and ultraviolet rays, keeping some of that heat out of your home. But don’t worry – these coatings don’t reflect visible light, so we don’t lose our view outside.

Other Benefits of Double-Glazed Windows

Reducing heat transfer is just one of the double-glazed windows many benefits to your home. For one thing, the extra layer of glass and insulating chamber can help to reduce noise. Just as that vacuum-sealed chamber keeps heat out, it can also stop sound waves dead, keeping your home quieter.

Double-glazed windows can also add a little more security to your home. Although they don’t guarantee a break-in won’t happen, they can deter burglars looking for an easy target. Two panes of glass are harder to break than one, and the improved frame construction makes these windows harder to damage.

Double-glazed windows work twice as hard to keep your home comfortable as single-pane ones. Everything from the vacuum-sealed chamber and reflective coating to the improved frame construction can help to retain heat from moving into or out of your home. These windows can also keep your home quieter and may provide some extra security.
