Choosing Windows for Brisbane Winters

Allkind Joinery & Glass sells, amongst many other prestige joinery products, timber windows. A look through their timber windows gallery will tell you half the reason why. There is no more timelessly stylish way to improve your home’s appearance than with timber windows and doors. While that alone may be reason enough to replace your aluminium framed windows with timber, it’s only half the reason. The other half is purely practical: timber windows can slash your energy consumption and save you money.

Brisbane is blessed with a relatively mild climate compared with other Australian capital cities. In the summer, average outdoor temperatures range from a pleasant 20 degrees Celsius to an equally pleasant 28 degrees. In winter, temperatures rarely dip below 10 degrees Celsius at night. While not too cold as compared to Melbourne or Sydney, Awning Windows Brisbanethat’s still too chilly for comfort in the home. The average temperature during the day in the Brisbane winter is around 21 degrees – perfect for jogging or working in the garden, but still a little too cool for comfort for relaxing in the home.

It’s no secret that energy bills are rising throughout Australia and if history is anything to go on, if you hold your breath and wait for them to fall, you’ll be holding your breath for a long, long time. The best way to fight energy bills is to tackle your energy consumption. One of the best ways to do this is to take steps to insulate your home against the winter cold. How do you do that? One of the best ways is with timber windows.

How Timber Windows Keep Your Home Warm in Winter

During the summer months, radiant heat from the sun is largely responsible for warming the house. During winter, a different type of heat transfer occurs. The Australian government’s Design for Lifestyle and the Future Technical Manual defines conduction as “the movement of heat energy through the glass and frame materials from the air on the warmest side to the air on the colder side.” In other words, while heat enters the home from outdoors during summer, it takes the line of least resistance to escape the home in winter. In almost all homes, the windows are that “line of least resistance.” The challenge to home owners is in finding ways to keep the house warm without turning up the heat or boarding up the windows.

Heat conduction is measured in “U-values.” Fortunately, you don’t need to be a physicist or an engineer to compute the U-value of your windows. It’s already been done for you. All you need to know is that the lower the U-value, the less heat that can escape your home. These are some of the U-values the independent experts have come up with for various types of frames and windows:

  • Aluminium frames have a U-value of 10
  • Timber window frames have a U-value of 2.8
  • 3mm clear glass has a U-value of 5.9
  • Uncoated 3mm double glazed glass with a 6mm gap has a U-value of 3.1

Those are some fairly dramatic looking differences, but do they make that much of a practical difference in your home? Well, the technical manual cited above suggests that your choice of windows can make an enormous difference, stating:

save money with timber windows“If your home has 70m2 of windows and glazed doors with aluminium frames with clear glass, on a winter’s night when it’s 15 degrees colder outside, the heat loss would be about: 6.2 x 15 x 70 = 6,510 watts.”

When the temperature dips to 10 degrees on an average Brisbane night and you’re trying to keep your home a comfortable 25 degrees, that’s probably the amount of energy you’re consuming if you have ordinary aluminium windows. If you replace your windows with double glazed timber windows, you can easily subtract 3000 watts from that number. How much is 3000 watts? It is equivalent to 50X60 watt light bulbs. Imagine how your energy costs would soar if you kept 50 lights turned on all night long.

While timber windows may cost more initially, they save money over time as they slash your energy bills both winter and summer. At the same time, they are a pleasure to live with and add substantial value to your home when you decide to sell. Your timber windows Brisbane specialist is Allkind Joinery & Glass.
