How Double-Glazed Windows Can Lower Your Energy Bills

Having double glazing in your home or business premises is such an obviously good thing that the only surprise is that some buildings in Australia don’t have it.

Double glazing makes sense for lots of different reasons. It makes the indoor temperature feel more comfortable by regulating the transfer of hot and cold in summer and winter, and it saves money on energy costs as a result. Never were two phrases more perfectly suited to each other, especially in Australia’s sometimes-unpredictable climate: regulate your indoor air temperature and save money. It’s an open-and-shut case.

So how much can you expect to save with double glazing? Are they worth the investment? Let’s delve into this topic a little further and explore how the improved levels of insulation with double glazing can help to lower your annual energy bills.

Improved Insulation

Double glazed windows offer a higher level of insulation compared to single-pane windows. They work by trapping a layer of air or an inert gas (such as argon) between the two planes of glass, generating a barrier that reduces heat transfer between the interior and exterior environment. This double layer of glass and insulating layer between them works to keep the building cooler in summer and warmer in winter.

Insulation coupled with uPVC frames also reduces drafts and fluctuations in temperature, creating a more comfortable and consistent indoor temperature. This reduces the need for air conditioning and, as a result, reduced heat loss in winter and reduced heat gain in summer.

Reduced Heat Loss in Winter

The space between the two panes of glass, which is often 6-20mm, acts as a thermal layer to reduce heat loss during winter. With temperatures dropping as low as 5°C (and sometimes 0°C in the outer suburbs) on the coldest winter nights, winter in Melbourne and Canberra can be unpredictable.

Heating costs can soar from June to August but there are several ways to bring down the price of your energy bill and make savings. Insulating your home better is one of the best ways to reduce heat loss and make the space more energy efficient.

Reduced Heat Gain in Summer

You don’t need us to tell you how difficult it is to keep your home cool on the warmest days of the summer. With average temperatures sitting at 26°C and occasionally soaring to maximums of over 40°C, sustaining a comfortable indoor temperature can be very costly.

Running a split-system A/C 8+ hours per day adds up and what’s the point in paying huge bills when the cool air is escaping through your windows? Upgrade the windows and doors in your home to double-glazing and you’ll notice a huge difference in your cooling costs.

Enhanced Comfort and Long-Term Savings

The effect double glazing has on homes all over Australia is amazing. Not only does it help householders to regulate the temperature, but it drives energy bills down because we don’t have to use the a/c or the heating so much. And as an added bonus, uPVC is pest-proof. Termites have zero interest in it because it is impervious to their natural munching habits, and because a closed uPVC window is sealed, they can’t squeeze in.

How Much Will I Save With Double Glazing?

How much you can save obviously varies from home to home, but the simple answer is: savings can be substantial when you choose high-quality Australian-made uPVC windows and get them fitted by a professional installation company. There are some specific factors that will directly determine the exact figure that you can expect to save. These include;

  • The size of your home and your windows
  • Local climate
  • Efficiency of your current windows
  • Features of the double glazing windows you’re installing (frame material, gas filling etc,)
  • Energy usage
  • Energy prices
  • Efficiency of your heating and cooling systems

They key takeaway? Find yourself a top supplier/installer who will remove and replace your current windows (and doors because the same advantages apply to them) and say hello to long-term savings on your energy bills.
