Double-glazed windows are an ideal energy-efficient choice with the added benefit of minimising noise. The sealed air gap between the two panes acts as an added layer of insulation. This added thermal resistance reduces the amount of heat escaping in winter and keeps your home at a more comfortable temperature.

Everything you need to know about double-glazed windows.

Windows play a large role in the efficiency of your home. But they can also be a big source of unwanted heat gain and loss. As the cost of energy rises, electricity bills become a burden. And, with up to 30-40% of heat energy lost through your windows, improving your windows’ efficiency can reduce energy costs.

What are double-glazed windows and how do they work?

Double-glazed windows are closed units made using two pieces of glass which are separated by an air gap of at least 12mm. The gap is sealed and acts as a break between the inside and outside pieces of glass. The air gap is filled with gas which increases the insulation between the glass pieces. Double-glazed windows are highly efficient, reducing your heat loss or gain by up to 30-40% when compared to single-glazed windows.

Single glazed vs double glazed windows

As its name suggests, a single glazed window is made using one panel of glass. This means the only thing between your home and the outside temperature is a panel of glass which doesn’t give adequate insulation. A single glazed window is not very efficient when it comes to heat loss or gain.

Double glazed windows use two panels of glass with a vacuumed air gap between them which creates an insulated barrier. Double glazed glass is laminated or tinted, but is similar to single glazed window glass otherwise.

What are the benefits?

The most obvious benefit of double glazed windows is the increased thermal efficiency. This means it is easier to maintain the temperature inside your house. This is important if you use air conditioners or central heating or cooling systems. Other benefits include:

• Energy-efficient
• Sustainable and environmentally friendly
• Reduces outdoor noise
• Durable with low maintenance
• Increases the value of your house
• Less condensation on your windows

The final word

The cost of installing double glazed windows is higher than single glazed windows. But they will pay for themselves with lower energy costs and a positive environmental impact. With so much to gain, these windows are the obvious choice for your house.
