What Are Double Glazed Units And How Can It Help You

What Is A Double Glazed Unit?

Double glazing is an excellent addition to any home. It is an energy-efficient choice for your home that helps to keep the warmth in. A double glazed unit contains two layers of glass with space in between. 

It is a versatile product that most modern homes have. That is because of the energy-saving properties of double glazing.

If you enquire at your local home improvements company, they will most likely recommend double glazing. That is because double glazed units have been continuously proven to benefit homes throughout the UK.

How Double Glazing Works

Double glazing contains two layers of glass that creates an air space. They then fill the air space in between with either argon or krypton gas. That is because this gas slows down the heat transfer between the panes. 

When the cool air outside hits the outer pane, the cold transfers to the air gap, creating a slow transfer of cold due to the argon gas. 

If double glazing is working, the cold air should never reach the internal pane. That is why condensation on the inner pane may mean your double glazed units are failing.

Why Is It Better Than Single Glazing?

Single glazing is quickly disappearing throughout the UK. That is because there is a better alternative. 

Double glazing provides a much better form of energy-efficiency. That is because of the air space between the panes. With single glazing, once the cool air transfers through the glass, it is in your home.

Are They Energy-Efficient?

Double glazing windows are energy-efficient. They are a cost-effective option that can reduce heat loss through your windows. 

Although triple glazing is now an option for peoples homes, it is more costly than double glazing. Upgrading from single glazing to double glazing will improve efficiency and may help to reduce your energy bills.

What Type Of Windows Have Double Glazing?

Another benefit of double glazing is that it is versatile. Double glazed units are perfect with uPVC, Aluminium and timber windows

Double glazing can also be used with conservatories, skylights or many other applications.


Double glazing is a fantastic choice for almost any home. That is because it is energy-efficient and affordable. 

The benefits you can get from double glazing are an excellent way to improve your home. 

Therefore, if you are interested in upgrading your home to double glazing, you should speak to your trusted window supplier.
