About Double Glazing

How does it work?

The magic of double glazing is in the separated space filled by Argon gas, the insulation caused by this pocket reduces heat transfer and sound transmittance. Argon gas is a colourless, odourless, inert gas that acts as a better insulator than regular air. Double glazing is effective in reducing heat transfer through conduction, convection, and radiation.

We liken double glazing to an esky. If the esky has warm things inside, it will stay warm. If there are cool things inside, they will stay cool. This is the same as your home.

In Canberra, it is important to get as much of the winter sun into your home as possible so that you receive free heating. The sun will enter your windows as shortwave and then once inside will convert to a long wave. The heating inside your home is already a long wave.

Glass is a good heat conductor and if the window is single glazed, the heat will transfer readily to the outside. You may notice in your single glazed home that by 4 pm, the home gets cooler and you need to turn on your heating – this is because your heat from the sun is travelling back out the window and as the sun is going down, there is no more heat coming in.

With double glazing, the air trapped inside the double glazed units is a poor conductor. If you have argon, it is a viscous gas and is denser than air. It would be like a top of the range doona with lots of air pockets. The trapped air (gas) sets up insulating protection between cool air on one side and warm air on the other. This is why your home stays warm in winter.

The opposite works in summer. We recommend that once the cool night air arrives, you open all your windows and doors and trap the cool air inside. Close them before retiring for bed and the cool air will remain in your home.

When paired with insulated uPVC frames, double glazing becomes a powerful shield against energy loss in your home.

Benefits of Double Glazing

Increased Comfort
By double-glazing your home, you can achieve a home that is warmer in the winter and cooler in the summer. Insulating the cavities where single-glazed conductive frames are typically found contributes to a well-sealed building envelope. This helps with maintaining your inside temperature, using your heating and cooling for less and ensuring that you are not loosing heat in the winter or gaining heat in the summer.

Noise Reduction
Standard double glazing can reduce transmission of medium to high frequencies (human voice), with at least a 12mm gap. For low frequencies (traffic) using a different thickness of glass in each pane, or using a laminated glass, can help to cut noise.

To achieve the best noise reduction, choose double glazed units with a very wide air gap between the panes of glass. The next best outcome is to use a laminated glass on the outside pane of the double glazing. An added benefit to this is that laminated glass is often harder to break than standard panes.

Energy Savings
Double glazing is an insulated product and will save energy costs such as gas and electricity in your home used for heating and cooling. By double glazing your  home, you will get the benefit of lower energy bills and help lower the carbon footprint of the building.

Putting solar panels on your roof will also cut down energy bills, however, it won’t provide the comfort that double glazing provides. You will still have draughts and uneven temperature in your home. Insulated windows and doors alone can save up to 45% on your energy bills and up to 75% when paired with solar panels.

UV Protection
We offer double-glazed glass units with low-emissivity coatings that block a significant portion of harmful ultraviolet (UV) rays from entering the building. This helps protect furnishings, flooring, and other interior surfaces from fading or damage caused by prolonged exposure to sunlight.

Bush Fire Attack Level
Our windows and doors are self-extinguishing and BAL rated, ensuring exceptional protection against bushfires. Designed to meet stringent Australian standards, these products provide enhanced safety and peace of mind while maintaining superior energy efficiency and aesthetic appeal. For BAL rated areas we upgrade the screens to aluminium mesh and thicker glass.

Why double glaze in Canberra

We live in one of the coldest places in Australia, and yet single-glazed aluminium, timber, or steel frames are the norm in our homes. In Canberra, we often use our heating for almost eight months out of the year and are constantly fighting to retain the perfect indoor temperature all year round. Uninsulated windows and doors are a recipe for disaster when it comes to feeling comfortable in our homes. Taking up over 30% of wall space, windows and doors become a weakness to the building envelope.

“Compared to Australia’s other capital cities, Canberra is unique. It has the fewest average rain days each year and is the country’s third-sunniest capital, but also freezes through an average of 99 frost days and 44 fog days each year. In summer it’s much hotter than its big neighbours to the north and south, and in winter it’s significantly cooler. Sometimes it even snows.”

By insulating and sealing the whole building envelope with insulated windows and doors, you will have a very comfortable home that is warm in winter, cool in summer, quiet and with no draughts, turning weak spots into the homes strongest feature.

Glass Types

A standard glass unit consists of two 4mm toughened glass panes separated by a 16mm spacer. For larger units and BAL areas, we use 5-6mm glass with a 12-15mm spacer for added strength. Depending on room orientation, privacy needs, or aesthetic preferences, a range of glass options is available to suit each space in your home.
