How Much Energy (and Money) Can You Save With Double Glazing?

How Much Money Can You Save With Double Glazing?

 

Installing double glazed windows and doors can help homeowners in Australia save up to 20% on their energy bills every year, while improving home comfort and reducing external noise. If your air conditioning and other cooling products run constantly in summer or your heating struggles to warm your house in winter, the real culprit could be your single glazed windows and doors. Poor door and window insulation leads to unnecessary energy loss, driving up both electricity bills and discomfort. Upgrading to double glazing is one of the most cost effective and efficient ways to fix this problem without getting new, major renovations.

Wouldn’t it be nice to sleep through the night again? With modern double glazed solutions, you can transform your house into a new, peaceful, and energy-efficient home that stays cool in summer, warm in winter, and quiet all year round in Australia.

Lower Your Energy Bills: Why Double Glazing Works

Double glazing works by creating an insulating barrier between your home and the outside environment. Standard single glazed windows and doors consist of just one pane of glass, providing little resistance to heat loss or heat gain. In contrast, double glazing windows and doors use two panes of glass separated by a sealed air or argon gas layer. This gap dramatically reduces thermal transfer.

Here’s how double glazed windows and doors reduce your energy consumption:

• Two panes of glass act as a physical barrier to heat flow.
• The argon gas between the panes provides superior insulation.
• Low-emissivity coatings reflect infrared heat, helping regulate temperature.
• Quality aluminium frames prevent leakage.
• Proper sealing during the installation service eliminates drafts.

 

By maintaining a stable indoor temperature, double glazing reduces reliance on air conditioning and heating products, directly lowering your consumption.

Window Type	Energy Efficiency	Heat Transfer	Noise Reduction
Single Glazed Window	Low	High	Minimal
Double Glazed Glass	High	Low	Up to 80%

Double Glazing vs Heat Loss: How Your Home Loses (or Saves) Energy

In Australian homes, windows and doors are often the weakest point in the building envelope. According to building energy efficiency studies, up to 48% of a home’s winter heat loss and around 90% of summer heat gain occur through windows and doors. Poorly sealed or outdated single glazed window and door product designs make your air conditioning and heating products work harder than necessary.

Installing double glazed windows and doors effectively reduces:

• Heat loss during winter
• Heat gain during summer
• Unwanted outside noise

 

By reducing leakage through your windows and doors, you’re able to run your heating and cooling systems less often, saving money.

Other product design options, such as sliding doors, double sliding doors, sliding windows, awning windows, casement units, hinged doors, bi-fold windows, or fixed panels, can all be configured with double glazing products to improve performance without compromising your home’s aesthetic. Whether in residential or commercial applications, modern double glazing is designed to suit both heritage properties and new builds in Australia.

5 Critical Factors That Affect Double Glazing Savings

Your potential savings depend on several key factors:

1. Glass Type and Coating: Low-E (low-emissivity) coated double glazed units can enhance thermal performance by reflecting heat.
2. Argon Gas: Filling the gap between panes of glass with argon gas reduces heat transfer significantly compared to air-filled units.
3. Window Frame Quality: New aluminium frames with thermal breaks help to minimize energy loss.
4. Professional Installation: Quality installation service by experienced double glazing installers ensures an airtight seal and long-term performance.
5. Window Placement and Size: Large north-facing windows will benefit most from energy-efficient upgrades. Choose appropriate designs like sliding, casement, or awning units to optimize efficiency based on your home’s design.

 

Choosing the right combination of these factors can maximise your savings and improve comfort year-round.

Is Double Glazing Worth It? Payback Time, ROI & Real Savings
