What are Double-Glazed Windows?

Double-glazed windows have become increasingly popular in modern construction and home renovations. They comprise of two glass layers separated by a small gap, often filled with insulating gas like argon or kept as a vacuum.

Designed to reduce heat transfer, double-glazed windows help homes stay warmer in winter and cooler in summer. They are also energy-efficient and offer additional benefits like noise reduction, setting them apart from regular windows.

How Do Double-Glazed Windows Work?

Double-glazed windows work by creating an insulating barrier between the two panes of glass. This space, as previously mentioned, can either be a vacuum or be filled with an inert gas.

• Thermal Insulation: The space between the double glass windows acts as an insulating barrier. This barrier prevents the cold air outside from coming in during winter and stops the warm air from entering during the summer. It also reduces heat loss in your home.
• Noise Reduction: Beyond just thermal insulation, the double layers of glass and the insulating gap also help eliminate outside sound. This makes double-glazed windows an excellent choice for homes in busy areas or near highways. 
   

What Type of Glass is Used?

Double-glazed windows can be made using a variety of glass types, each tailored to specific requirements and purposes.

• Clear Glass: This is the most common type, offering clear visibility while providing insulation.
• Low-E Glass: Low-emissivity (Low-E) glass has a thin metallic coating on its surface that reflects heat, making it efficient at thermal insulation.
• Tinted Glass: Tinted types can reduce glare and absorb heat, making them a good choice for homes in sunny regions.
• Laminated Glass: Comprising two or more layers of glass bonded with an interlayer, this type offers improved security and noise reduction.

The Benefits of Double-Glazed Windows

Double-glazed windows offer countless advantages that go beyond just looks and are a testament to how advancements in construction technology can improve our daily living conditions. Here are some of the main benefits that make them the best windows for new homes.

Minimise Noise 

Noise can be a huge concern for those living in active city areas or near busy roads. Double-glazed windows act as a barrier against sounds from the outside world. In double glazing, the two glass panes, combined with the insulating gap between them, effectively reduces the outside noise from coming inside our homes. Single glazed windows lack the noise-reduction capabilities that double glazing provides.

Energy Efficient

One of the biggest features of double-glazed windows is their excellent energy efficiency. The insulating layer of double glazing, stops the transfer of heat from fresh air to cool air. This means during colder months, the warmth from your heating system stays inside, and during warmer months, the heat from the sun is kept out. As a result, there's less use of a heater or an air conditioner, leading to lower energy bills.

Improved Security

Safety is a top priority for every homeowner, and double-glazed windows offer an added layer of protection over single-pane windows. The presence of two glass panes and multiple layers enhances their durability, making them tougher to break and more difficult for potential intruders to gain access. Additionally, many double-glazed windows come equipped with advanced locking systems, further reinforcing their security features. 
 

Improved Climate Control

Beyond energy efficiency, double-glazed windows give homeowners better control over their indoor conditions. The double glazing means fewer cold spots, and less heat, resulting in a more consistent and comfortable temperature throughout the home. This type of control over air space is particularly beneficial for homes in areas like remote Queensland, where extreme seasonal temperature changes are common.

Protects Against Condensation

Condensation, which often forms on single-pane windows during colder months, can lead to mould growth and damage to window frames. The insulating gap in double glazing makes sure the inner pane and entire window remains closer to room temperature, reducing the chances of condensation forming. Extending the lifespan of your window frames.

Single vs. Double Glazed

The biggest difference between single and double-glazed windows is their structure and insulation properties. Single-glazed windows have just one pane of glass, while double-glazed windows have two, separated by an insulating gap. This can make double-glazed windows heavier and more expensive compared to their single-glazed counterparts.

How Much Do Double-Glazed Windows Cost?

The cost of choosing double-glazed windows varies based on factors like size, type of glass, frame material, and the cost of installation. They can also have higher upfront costs compared to single-glazed windows. 

Considering the long-term savings on energy bills and potential increase in property value, many homeowners find the investment in double glazing well worth it. On average, they can cost $800 per square metre up to $1,500 per square metre installed, depending on the size of your home.
