Q What is double glazing? How does it function?

A. Double glazing is comprised of two glass panes and a layer of gas argon within the middle.

Why is argon gas needed?

Argon gas is not a good conductor of heat. When you place Argon gas in a middle you’re stopping heat from leaving leading to better energy efficiency and lower energy costs.

Q: Can double glazing help reduce noise?

A: Double glazing can offer noise-cancelling properties as the two glass panes limit the amount of sound that can be heard in your home.

Q: In the event that you find the windows scalding with steam but you can’t get rid of the condensation because it’s being in the windowpane it might be the right time to get the double glazing units replaced.

If this occurs then you might need replacement of the whole window, if there are any other issues with the frame or seal because this could prevent new double-glazed windows from being efficient.

Q: Can double glazed windows crack?

A Double glazing is composed of extremely durable materials, which means the chances of it cracking are low.

However, this doesn’t necessarily mean that double glazing is impervious to cracking, particularly after some time.

It is possible that it will crack because of severe weather conditions, in particular in the event of scratches. This can cause the glass to become more fragile and less durable.

The high humidity and temperatures also can have an impact – particularly in areas like the kitchen or bathroom where condensation can be in high levels.
