Are Double-Glazed Windows Worth Installing in Your Home?

There are a handful of home improvements that are quite commonly cited as being incredibly beneficial both while in use and for increasing your property value. Hardwood floors, a new roof, and bathroom remodels all come to mind, but double-glazed windows are one such investment that are almost always worth considering for your home.

What are Double-Glazed Windows?residential windows

Just about every new home in Australia comes with double-glazed windows as a standard, so they’re extremely common and perhaps the only places where you’ll find single-pane glass windows are heritage homes or structures that don’t necessarily care about double-glazing, such as storage sheds.

Double-glazed windows are windows consisting of two panes of glass separated by a narrow gap either filled with air or with an inert gas (e.g. argon). This gap provides insulation as well as a bevvy of other benefits when compared to single-paned windows, so much so that there are virtually no practical benefits to these old windows in any liveable space.

Double-Glazed Window Energy Efficiency

The first and most frequently mentioned benefit of double-glazed windows is their energy efficiency. All windows are generally inefficient, but of course you need windows in your home. Single-paned windows often lose 70% of more of heat from within your home, but double-glazed lose around 50%.

In terms of energy bill consumption, double-glazed windows can lower bills by about 30% due to their superb insulative properties that help keep homes cooler in the summer and warmer in the cooler months of the year. To give an example, if you’re spending around $1,300 per year on energy for your home, double-glazed windows could potentially save you around $250-$400 every year.

Noise Reduction

Another great reason to consider double-glazed aluminium windows for your home in Melbourne or elsewhere is their superb ability to block out unwanted ambient noise from the street such as traffic, neighbours chatting, and so on.

Single-paned windows do block out some noise, perhaps around 25dB or so, but double-glazed windows can block out around 50dB so long as the window panes are thick enough and the gap is well-spaced.

Increased Home Security

Most burglars in Australia are opportunistic and aren’t like those caricatures you might have seen on children’s cartoons, carrying around a sack of lockpicking equipment to break into properties.

A burglar will most often try to open the front door, and if it’s locked, perhaps try a window if within reach. Double-glazed windows provide an essential first line of defence and deterrence to burglars since they can be fitted with locks and can pose too much of a hindrance to a potential burglar.

Increase Your Property Value

Like with hardwood floors, a new roof, and bathroom remodelling, double-glazed windows are an investment that is well-known to increase property value. Prospective buyers are keen for these sorts of improvements and, because double-glazing is essentially standard for new builds, it is practically an expectation from buyers.

Is it Worth Installing Double-Glazed Windows in Your Home?

There is no doubt about it: double-glazed windows are a must-have for homeowners. If your home still has single-paned windows, you’re missing out on the many benefits of double-glazed windows. For most homeowners in Melbourne, double-glazed windows are an absolute must-have.
