Double glazed units are good insulators because they have an air space between two or more panes of glass.

A still layer of gas and a spacer made of a metal or polymer strip usually with a drying agent are used to separate the glass panes. This extra pane prevents heat from passing through the window, making them highly effective insulated glass units with great thermal performance.

In cold climates, double glazing is really important for your home's overall energy efficiency and can dramatically reduce heating costs during the winter months. In hotter climates, it works as a barrier against the sun's rays so you won't be paying extra to cool a room that has been overheated by direct sunlight.

The amount of double glazing which should be installed in homes varies depending on the local climate but generally, homeowners looking for energy efficient houses would benefit from having at least two layers of glass in each window.

Triple glazing is popular, but in some climates, it might be more effective to have four or six layers in each window.

The best thing about double glazing is that it can be fitted into an existing uPVC window frame, making it easy for homeowners to stay within budget and make the most of energy-saving technology without having to replace all the windows in their home.

Why are double glazed windows efficient thermal insulators?

Double glazing is highly effective at thermal insulation. This means that the trapped air between the two panes of glass prevents heat loss from inside your house, and saves you money on heating and power bill. It also prevents your windows from condensation when inner temperatures are warmer than outside.

The air gap between two sheets of glass prevents heat from passing through the window. In cold climates, double glazing is really important for your home's overall energy efficiency and can dramatically reduce heat loss resulting in decreased heating costs during the winter months.

In hotter climates, the increase in thermal performance it works as a barrier against the heat and direct sunlight from entering your house while preventing heat gain keeping your house cool so you won't be paying extra to cool a room that has been overheated by the sunlight.

It's important to note that the insulating efficiency of these windows depend on a number of factors including: the glass thickness, glass types, which gas is filled in the air space between two panes, low e glass and whether the glass is fully sealed or not.

How long do double glazed windows last?

A double glazed window will typically last for between 20-30 years, depending on the quality of materials used in its construction. If you are looking to improve your home's energy efficiency but are concerned about the exterior aesthetics of your windows over time, then installing double glazing is a wonderful idea.

Which is a better-insulated window, single glazed windows or double glazed windows?

Depending on the climate you live in, there are lots of factors that will affect whether you should have a single pane or double glazing installed. In cold climates, double glazing is really important for your home to be energy efficient and can dramatically reduce heating costs during the winter months. In hotter climates, it works as a barrier against the heat and sun's rays so you won't be paying extra to cool a room that has been overheated by the sunlight. However, it comes with the added benefit of not blocking out radiant heat. This let's warm and fresh light enter your house during all seasons. If you are looking to improve your home's energy efficiency but are concerned about the exterior aesthetics of your windows over time, then installing double glazing is a wonderful idea. This type of product is not only more energy efficient but also more cost-effective for homeowners who do not wish to upgrade their entire window frame.

What insulation is used in double glazed windows?

Double glazing is an insulator because it has an air space filled with gas between two panes of glass. This air space prevents heat from passing through the window, saving homeowners money on yearly energy bills. Quartz glass is becoming increasingly popular in thermal window construction because it has unbeatable thermal insulation properties. The inert gas contained inside this type of glass can help to improve its overall insulation performance by nearly 4%. Another popular glass is the low e glass which can help alter the light transmission capacity of a window when heat, light or voltage is applied to it. Double glazing units are made up of two panes of glass separated by a sealed air gap chamber, which makes them excellent insulators against both forms of heat transfer (conduction and convection).

What gas is used in double glazed windows?

Double glazed windows get their insulating power from the air or gas inside the sealed cavity between the two panes of glass. This gas is usually argon, krypton or xenon. Argon and Krypton are inert gasses, which means that they do not react with other compounds around them; this makes them perfect for regulating the pressure in double glazed window units.

What does uPVC mean?

uPVC stands for Unplasticized Poly Vinyl Chloride - a type of thermoplastic polymer resin which has become one of the most popular types of window (and door) frame material other than aluminium frames to be installed in homes across Great Britain because it is durable , cost-effective and aesthetically pleasing . Many uPVC window manufacturers offer double glazing made from this material, but make sure you ask them what type of gas they fill the cavity with; argon and krypton are more energy efficient than air.

Do double glazed windows reduce household energy costs?

A double glazing window system will typically reduce the amount of heat energy needed to cool up your house by between 8 and 15 percent by blocking out unwanted heat gain while maintaining your home to a comfortable temperature. This can help you make significant savings on air conditioner costs.

By installing double glazing units in your home, you can save up to 20% on energy costs during the winter months and keep cold air inside when temperatures rise outside due to its better thermal performance.

Also, double glazing works to help prevent condensation from forming on the panes of glass inside a room so you don't have to worry about water droplets from the air obscuring your view or window frames rotting away from the condensation caused due to the excess moisture trapped next to them. The Australian Government's Your Home website has some great information on glazing.

How long does it take to install double glazed windows?

Typically, a team of professional window installers can finish the job from start to finish within a day if everything has been pre-ordered correctly and there are no obstacles in their way. If you have just bought a new home but still have single glazing installed, then it might be best for someone to return once all your double glazed units have been delivered so they can get started right away.

Do double glazed windows reduce outside noise?

Yes - an excellent example of this is when you look at how much more insulated car windshields are compared to the windows in your home.

A soundproof double glazed unit can help reduce high-frequency noise up to 10dB.

Noise pollution has been proven time and time again to have a negative effect on people's sleep patterns and general well-being, but double glazing can help to alleviate this problem for homeowners who live in neighbourhoods that are regularly subjected to loud noises from traffic or industrial machinery by providing maximum noise reduction.

In addition, double glazing often come with special coatings that prevent rain from getting through them while still allowing light rays from the sun inside - these coatings will do a lot to ensure good visibility without any distracting reflections from the outside world.
