Double Glazed Windows Melbourne – A Practical Buyer’s Guide for Australian Homes


If you are searching for double glazed windows in Melbourne, chances are you are tired of high energy bills, cold winter drafts, or traffic noise coming straight through your glass. This guide is written for real homeowners, not architects or engineers. You will learn exactly what double glazing is, how much it costs, how to choose the best windows, and how to avoid the common mistakes that waste thousands of dollars.


What Are Double Glazed Windows?

Double glazed windows are made with two panes of glass separated by a sealed air or argon gas gap. This gap creates insulation that blocks heat, cold, and noise from entering your home.

Single glazing lets heat pass straight through. Double glazing slows that transfer dramatically, which is why your house stays warmer in winter and cooler in summer.


Why Double Glazing Is Important in Melbourne & Canberra

Melbourne weather is unpredictable. Canberra winters are harsh. Both cities suffer huge heat loss through standard windows.

Typical Australian homes lose:

  • 40% of heat through windows

  • 30% of air conditioning through poor glazing

Installing double glazed windows in Melbourne or Canberra instantly reduces heating and cooling costs while improving indoor comfort.


Main Benefits of Double Glazing


1. Lower Energy Bills

Double glazing reduces heat loss by up to 40%. That means:

  • Less heater usage in winter

  • Less air conditioning in summer

  • Lower electricity and gas bills every month


2. Noise Reduction

If you live near traffic, schools, trains, or busy streets, double glazing cuts outside noise by 60–70%.


3. Increased Home Comfort

No more cold spots near windows. No more condensation dripping down glass.


4. Improved Security

Two glass layers are harder to break, which increases home safety.


Why uPVC Double Glazed Windows Are the Best Choice

uPVC is the most popular frame material in Australia for double glazing.


Advantages of uPVC Windows

  • Naturally insulated

  • Does not rust, rot, or warp

Cheap Double Glazed Windows – What to Watch Out For

Cheap double glazing often means:

  • Thin frames

  • Poor seals

  • No argon gas

  • Weak warranty

This results in foggy glass, air leaks, and wasted money within 2–3 years.

Rule: Always invest in quality installation, not the lowest price.
