How Effective is Double Glazing?

Double glazing is a growing trend in Australian residential construction for its many benefits, but as with everything that’s ‘trendy’, there are plenty of misconceptions as well surrounding its efficacy in insulating your home.

Here’s the nitty-gritty of double glazing window efficiency and how Stop Noise beats out traditional double glazed windows with its superior technology.

No Amount of Glazing Fully Insulates

It doesn’t matter what it’s made of, windows are always the weakest point of insulation in a home. Having said that, single glazing is wholly ineffective against the elements with an R (insulation) rating of about R0.15.

Double glazing more than doubles the effectiveness by boosting the R-value to R0.5. Compare this to an insulated wall with an R3.0 and it’s clear to see that no amount of glazing will turn a window into an insulated wall.

Put that into perspective. An insulated wall is six times more effective than double-glazed windows. Obviously, no one would want to build a home without windows for the sake of better insulating efficiency, but the choice of how many windows and of what calibre they are will have profound effects on heat absorption, dissipation, and also sound reduction capabilities for your home.

Determine Glazing Efficiency Reliably

If you’re in doubt about the efficacy of glazing and insulating R-values in your home, consult the Australian Building Codes Board for their NCC 2019 Glazing Calculator which lets you determine how effective your insulation will be.

Stop Noise’s double glazing technique has proven to be reliable for all of the benefits that double-glazed windows provide and more. For this reason, our technique is not trying to ride the wave of double glazing as a trend but rather showing through experience and proven results that our double glazing technology works wonders for homeowners.

Australian Window Association

Are you unsure about the claim of a double-glazed window manufacturer about the veracity of their effectiveness? The Australian Window Association has prepared a website, EfficientGlazing.net, which empowers Australian consumers (you!) to make informed choices when considering different types of windows for your home.

As a point of interest for those considering double glazing, the Australian Window Association advocates for double glazing over other alternatives such as low-e glass. Not only is it more effective at insulation and noise reduction, but its cost is coming down as well due to its use in over 50 per cent of all new residential construction in Australia in recent years.

Is it Cost-Effective?

Definitely yes. Double-glazed windows are so popular that their cost has lowered significantly, making it only marginally more expensive than single-pane windows. The upfront costs are not all, however.

In terms of ongoing costs, double-glazed windows offer far better results in insulation, which itself greatly lowers the costs required to heat or cool the home. In the long-term, double-glazing, especially using the technique of Stop Noise, puts money right into your pocket and helps the environment at the same time.

Stop Noise

Many homes still use single-pane windows and need to be removed and replaced with double glazing to make them more efficient. There is another option. Stop Noise offers retrofitted double glazed windows custom built to fit right over your existing window for a much-needed boost in insulation, noise reduction, and cost-efficiency.
