Many modern homes in Australia have double glazed windows. These are insulated glass units that combine two glass panes in a single window system. Here are some main benefits of double-glazed windows.

Energy Efficiency

Australians pay the highest prices for power in the world. One of the ways you can offset energy costs is by installing double-glazed windows. These windows are energy efficient. The sealed gas gap between the two glass panes provides thermal insulation. Double glazing locks in cool air during hot weather, leaving the excess heat outside. During cool weather, the windows prevent heat from leaving your house. 

A significant amount of energy in Australian households is used for powering heating and cooling appliances. The functions of double-glazed windows minimise your reliance on a heater and cooler. This results in huge savings in energy.

Prevents Water Damage

If you pour cold water into a glass pane, the glass becomes misty. This is called condensation. It occurs when warm air is subjected to cool conditions.

When your windows are subjected to heat from the outside, water droplets form on the windows. Similarly, when the air inside is warm and the outside air is cold, water droplets form on the windows. The water droplets can penetrate through your window frames or pass through your walls.

In the long run, this could lead to water damage. The consequences of water damage include health problems such as lung infection or asthma attacks. One advantage of double-glazed windows is how they minimise the chances of condensation and water seeping into your walls. The inner layer of the window is a barrier between the differences in temperature between the inside and outside air.

Soundproof

No one likes people eavesdropping or overhearing their conversations. Double-glazed windows can help minimise noise when you are involved in private discussions. The structural elements of your home insulate it against unwanted noise. Your doors and windows are the weakest elements against external noise. The performance of windows is measured using a weighted sound reduction index. 

This index measures how well a door or window blocks external sound. The higher this rating, the better your window is at blocking noise. The space between double-glazed window glass panes helps minimise external noise. These windows have a higher weighted sound reduction index and are often soundproof. You can add special acoustic layers to the glass to improve its insulation and sound reduction properties.
