It is important to understand the benefits of Double Glazed and Triple Glazed Windows, so you can make informed decisions about not only your window frame, but also the glass glazing choice, that will meet your requirements.
What is Double Glazing?
Glass Glazing refers to the number of panes which sit within the window frame. So Single Glazing is one pane of glass in the frame. Double Glazing means there are two panes of glass, sitting within the window frame, separated by a spacer. Triple Glazing means there are three panes of glass attached and separated by a spacer.
Other factors which impact the double-glazing effectiveness include:
- Glass Type and Window Film – Whether it is Low-E or tinted glass, and the glass thickness
- Window Frame – what type of material it is made from, such as aluminium or timber
- Gap Filling – the efficiency is impacted by what is in-between the glass (whether it is air or argon gas)
Our Window Experts will walk you through the different window glaze options, and help select the right type of glazing to suit your budget and lifestyle.

Triple Glazed & Double Glazed Windows
What You Should Look For
Making carefully thought out decisions and wise choices when choosing thermal glazing will greatly improve the comfort for those of you who are near or close to windows, especially very large windows. Our ideals of comfort are not just air temperature but we also take into consideration the entire surroundings that can have an major impact on our customers.
Our main objective is to have an indoor glass surface temperature that is as close to room temperature as possible. This equates to glass that is neither cold in the winter months nor warm in the summer months. The value of U-value (as Uw in windows) measures how well a window system conducts heat.
How It Works
The rate of heat is shown in terms of U-value in window assembly which includes the frame, the seals, the glass and spacers. The lower the U-value, the higher the window’s resistance to heat flow along with the greater its insulation value. The SHGC (solar heat gain coefficient) for windows shown as SHGC, measures show how quickly direct sun streams through a window system. The SHGC is the fraction directly conducted, as its absorbed and thereby released inward.
SHGC is rated in a number value between 0 and 1. The lower the SHGC, the less solar heat is being transmitted. The angle that solar radiation hits glass has a major impact on the amount of heat is being sent. At the point that the sun is perpendicular to the glass, it’s angled at 0 degrees. 85% of solar heat is transmitted with standard glass.
The angle will increase with the higher solar radiation being reflected and less being sent. Once the angle surpasses 55 degrees it falls sharply. The effective area of exposure to radiation reduces as the angle increases. Under the Building Code of Australia (BCA), manufacturers of windows are required to maintain windows and doors meet the minimum specs for structural adequacy and water seepage resistance under Australian Standard (AS) 2047. Energy adequacy provisions dictate that a window’s performance must met in agreement with guidelines of the Australian Fenestration Rating Council (AFRC).
Thousands To Select From
There are thousands of glass and frame styles to choose from. Choosing the ones that are right for you is critical to improving your energy effectiveness within your home. There are certain products that are deliberately designed to keep heat in or out and vary in regards to daylight, noise, maintenance and security. The price of a window and the cost of heating and/or cooling your home are succinctly related. The initial investment in energy windows will greatly reduce your heating and cooling bills.
Good energy efficient windows will also reduce those peak heating and cooling hours and reduce an air conditioning system by 30%. This in turn, will also reduce your costs, offering a greater savings.
The Australian Window Association has created a tool (see www.efficientglazing.net) that will calculate the savings you may experience with energy efficient glazing. This handy tool compares various window selections to a common aluminum window with 3mm clear glass.

Double Glazed Windows FAQ
While double glazed windows are not a new concept by any means, there are nuances and differences that exist between double glazed and standard windows. Knowing these differences can save time, energy costs, and hassle in the long run when looking to install or replace your windows.
Below is a comprehensive frequently asked questions (FAQ) list of some of the most commonly asked questions we get here at the Perth Window and Door Replacement Company. Have a question not covered in the below? Feel free to contact us and we will be more than happy to provide our expert advice.
What are double glazed windows?
Double glazed windows are windows that consist of two panes of glass, separated by a very thin layer of argon gas. This trapped argon layer boasts 2/3rds the thermal conductivity nature of standard air. This makes it a bad heat conductor. The poor conductivity leads to warm air being sequestered into the home, improving energy efficiency of your house or dwelling.
Additionally, the additional glass paine acts as an added sound barrier. This serves the purpose of keeping the home padded, as the window areas are where most sound escapes. It also serves to improve the overall strength and security of the window.
Are double glazed windows soundproof?
While double glazed windows are in no way completely soundproof, they do provide a significant increase in overall noise reduction. Installing double glazed windows instead of standard fixed window alternatives provides a clear reduction in the outside noise heard from inside, and the inside noise heard outside.
The overall amount of noise that is blocked or reduced by double glazed windows is dependent on several factors. A few of these include sizing of vents, age of the windows, structural integrity of the window frame, and quality of the double glazing process.
How are double glazed windows made?
The process to manufacture double glazed windows is surprisingly simple and straightforward. Initially, two single panes of glass are separated by spacers. Then, airtight, hermetically sealed gaps are created. These gaps are then filled with inert gases, with argon being the most commonly utilized. These gaps are filled in a vacuum, to prevent the formation of condensation, as well as stopping moisture from seeping in between the glass panes.
The expanse of the gap is dependent on both the type of windows and the type of gas used to fill the gap. Typically, the gap ranges from 10 to 20 millimeters. There is also triple glazing, which is made in the same process, but utilizes three panes of glass and two cavities of inert gases.
How does double glazing save heat energy?
Double glazed windows are far different from single pane windows. Through more advanced technology, and a thin layer of inert gas between layers of glass, the inner glass pane reduces the amount of heat lost through the window, and the outer pane of glass allows the sun’s heat to penetrate through and inside your home. You get the light, but without the intense heat of the Australian sun.
How much is double glazing?
The costs associated with installing double glazing into your home is entirely dependent on the size of your home, as well as the number of windows you are looking to upgrade. Regardless, it is a safe expectation to estimate several thousand dollars for a complete installation. Double glazing is a competitive market in Perth. For this reason, it’s important to shop around and determine the best possible deal for your new home or home renovation project.
Working with a tight budget? It may be beneficial to go piecewise, and double glaze the most used rooms in your home first.
Why are my double glazed windows wet on the inside?
The wetness seen on the inside of double glazed windows is condensation. This is often an occurrence when the surface temperatures of the windows are far cooler than the air found inside the rooms. If seals around the glazing have failed or are of poor quality, warm air is prone to entering gaps between glass panes.
When the warner air contacts the cold air present between panes of double glazed windows, condensation forms. This is no different than the condensation found on windows that are not double glazed. However, as double glazing in windows seals in the gap, there isn’t a place for moisture to escape.
If left completely untreated, window condensation can slide down the glass and onto the walls below your window. This can lead to issues from black mold to wet/dry rot. Double glazing condensation can also be disappointing as it leads to the fogging of views.
Do double glazed windows keep heat out?
Double glazed windows serve to keep the hot Australian sun from heating your home year round. The design of these windows created insulated breaks between the indoors and outdoors. This keeps the heat out during the hot summer months.
Traditional windows are made from single sheets of glass. Double glazed windows have two panes of glass and argon gas between, which creates an insulation break. The gap limits the heat from outside that can make it through to inside the home.
