Your Double Glazing Questions Answered

Most of us have heard of double glazing, but how many of us know exactly what it is? We’ve answered some of the top double glazing questions to help you understand how it works.

There are 5 things it’s essential to know if you want to understand double glazing.

Whether it’s about the type of glass or the gas that is used in windows, we’ll shed some light on double glazing here.

1. Why is it called double glazing?

You probably already know this, but just for clarification, double glazed windows have two panes of glass. They’re separated by spacers to make a thicker pane, but more on that later.

2. How does double glazing keep more warm air in?

The two panes of glass are separated by spacers, with the gap filled with Argon gas. Argon is denser than air, which means it stops cold air passing through the final pane of glass that’s inside your house.

Ideally, you’ll want a 20mm gap between each pane. Since you can’t have really thick windows, this measurement has been set as the best space to have between the panes of glass.

3. Is there just one type of glass?

No. These days, you can have self-cleaning, anti-glare, sound reduction glass – just to name three. All of the different types of glass have their own unique properties that can be beneficial to you, depending on your circumstances.

4. What is “Low-e” glass?

Low-e glass, or ‘low emissivity’ glass is the most popular tint that you may have heard of recently. Glass with a low-e tint reflects heat, so you should place it on the inner pane of your window to stop heat from escaping.

As well as low-e glass, there’s a tint called low iron. It does the opposite to low-e so allows heat in, meaning it’s perfect for the outer pane of your window.

5. Will I have a warmer home with double glazing?

This is possibly one of the most important double glazing questions. You should notice that your home is warmer and free from draughts with double glazing. But windows must fit perfectly into the frame and the space around them, otherwise they could be letting heat escape.

You’ll know if your windows aren’t fitted properly because you’ll be able to feel draughts from around the windows. You might also notice damp or mould near or on window frames.
