Does Double Glazing Keep the Summer Heat Out?

Summer is nearly here – which is great news until you get your energy bill. 

Heating and cooling accounts for 40% of household energy costs on average. With the price of power tipped to rise 50% in the next two years, Australian families are in for a shock. 

Federal Treasurer Jim Chalmers told ABC TV that Australians will “have these challenges ahead of us for a little bit longer than we’d like” and admitted he didn’t know when costs could ease.

The Government is looking long-term. 

Households should be doing the same. 

But unlike the Government’s decades-long investment timeline, you can make an investment now that will start paying off as soon as this summer.

Double glazing is a highly effective insulator that regulates your home’s temperature in all weather, cutting heating and cooling requirements by up to 50%.

How double glazing keeps Perth homes comfortable in summer

Double-glazed windows and doors limit thermal transfer. Unlike regular glass, which has almost no effect, double glazing clad in uPVC frames improves your home’s thermal performance.

Up to 87% of a home’s heat comes through single-panel windows

Double glazing can halve your home’s heat transfer 

Energy-efficient glazing means your AC unit can be 30% smaller

Installing double-glazed windows, doors, and skylights will significantly reduce cooling requirements in summer. Provided, of course, you get high-quality custom-made doors and windows designed for the harsh Perth sun. 

It works like this:

An outer layer of coated glass reflects long-wavelength UV rays fade furniture and cause skin cancer.

Exterior heat (sunlight) is reflected back.

A gap filled with argon gas or desiccated air slows heat particles.

The internal pane adds another heat barrier.

Interior cool air reflects back off the inner pane.

All three layers in double glazing work together to regulate internal temperatures. Secondary glazing – adding a panel to single-glazed windows – can have some benefits, but the cost and hassle outweigh energy savings.

Do the benefits of double glazing scale?

You can be forgiven for thinking that the benefits of double glazing in Perth drop off for large panels. But the opposite is true.

The bigger the glass panel, the bigger the energy savings. According to the DCEEW, replacing single-pane glass with double glazing and less-conductive uPVC frames can halve heat transfer.
