How to make windows work for energy efficiency


“Glazing is the weak point in the thermal envelope if you’re using standard glass and a standard frame like aluminium.”

Wheeler says a good rule of thumb to follow is to have windows making up no more than 25 per cent of the total floor area of the house, and to place them carefully.

“Once you go beyond that 25 per cent there will be a heat exchange through that house that no amount of insulation in the walls and roof will compensate for,” he says. “You need to look at position, orientation, size and how the windows open. And if you’re going to glaze more than 25 per cent, upgrade your glass.”

Australian Window Association CEO Tracey Gramlick says up to 40 per cent of a home’s heating energy can be lost through windows and up to 87 per cent of its heat gained through them, so it’s well worth investing in energy-efficient windows.

Renovations; New Doors New Windows This may help deciding what you need


If there’s one thing guaranteed to cause arguments, it’s renovations.

Aside from the disruption of having tradies traipse through your home, the confusion over whether certain facts were actually communicated, and the sharp sense of unease watching the bank balance shrink, the biggest bone of contention has to be the vast array of choices.

We’ve gotten through bathroom taps, the toilet, the hand basin and what to cover the floor with. But the showstopper this week was something seemingly innocuous – the door.

The statement “I’ve ordered the door”, was met with stony silence. On one side of the fence is the argument for a bog-standard single-pane glass entry door that lets in plenty of light and garden views, but also heat and cold.

On the other is the desire for, at the very least, double-glazing, preferably with a low-emissivity (low-e) coating on one face to make the set-up more efficient.

Both sides of the fence are happy with a timber frame, which although requires more maintenance, suits the style of the house and is more energy efficient than standard aluminium.

The main sticking point is the price difference of the two different glazing options (several hundred dollars at most suppliers), and the fact that, as most companies don’t offer double-glazing as standard, it will throw the wait-time for the door out past Christmas.

For all the talk of building more energy-efficient homes, it seems most suppliers are still playing catch up. Few have off-the-shelf double-glazed doors, and those that do, stock them in limited sizes.

One company I contacted this week said they used to do a double-glazed unit, but found the double-glazing didn’t fit their doors so now they only offer single glazed.


While the argument is not yet settled on the domestic front, and the door deposit has not actually been paid, there has been plenty of reading of the Window Energy Rating Scheme (WERS) website, in particular the climate zone map and the window comparison tool on the Efficient Glazing site.  NOTE: this is for Australia;  USA uses Energy Star check out their website at: http://www.energystar.gov

DIY: New Windows

For the experienced DIYer, installing a new window should be a comfortable weekend project.

Keep in mind they are heavy objects to haul and lift, so you’ll need to enlist a burly helper to assist.

And pay particular attention to correct waterproofing.

Will putting in new windows add value to your home?  Contact the appraisers at www.socalappraisalserv.com for value questions.

Check with your local council first to see if you require approval for the window. If it’s going into an entirely new spot or is significantly larger than the one being replaced, chances are you’ll need to put in a development application (DA).

Getting started

There are many different windows to choose from: bifolds, sash windows, sliding windows, louvres, casement windows etc.

Browsing a few window supplier websites or showrooms will give you a good indication of the type of window best suited to your application.
