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 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.
