uPVC Double Glazed Windows in Australia

uPVC Double Glazed Windows in Australia: Video

 

Available across Europe and America for the past 60 years, uPVC window profiles are the most popular choice to deliver superior and proven performance worldwide.

More than half of all new and replacement residential windows worldwide are uPVC. That’s almost 290 million window units a year.

Chosen for their durability, low-maintenance, high energy efficiency, performance and style, the US and Europe have long focused on energy-efficient windows.

However, in Australia, we’ve traditionally used either timber frames which are good insulators but high maintenance, or aluminium window frames which need less maintenance than timber, but have poor insulation .

Thermal performance is one of the most important characteristics of a window. Double glazed uPVC windows can be as much as four and-a-half times more energy efficient than standard single glazed aluminium. The energy efficiency of a window system is commonly defined by two measures.

First, the solar heat gain coefficient (SHGC), a measure of the solar radiation going through the glazing into a building, and secondly by the rate of heat flow through a window system (uValue). For both measures, the lower the number, the higher the performance.

A common misconception in Australia is that double glazing is only for cold climates, to keep the cold outside. But double glazing is also just as effective in keeping the heat of an Australian summer OUT. In fact, standard glazed windows contribute to eighty-seven percent of the summer heat gain in a typical Australian insulated home. Choosing double glazed units with low solar heat gain and lower uValues reduces or eliminates the need for expensive artificial cooling. By replacing your windows with high-efficiency upvc ones, you can reduce greenhouse gas emissions from household heating and cooling by more than one ton a year.

uPVC windows are considered durable, with expected life spans of 35 years, and leading brands have been tested specifically for resistance to australia’s high UV radiation levels. These windows will look good for years without the need for sanding or repainting, and being resistant to salt, are ideal for coastal locations.

uPVC window profiles have been carefully engineered to incorporate multi-point locking systems, providing a high level of security. They can be used in a wide range of styles for old and new heritage or contemporary homes, and they come in a variety of colors. Choose with confidence from a range of quality suppliers in Australia.

Wherever you live in Australia- Brisbane, Sydney, Canberra, Melbourne, Hobart, Adelaide or Perth, you can benefit fromt the qualities of uPVC double glazed windows and doors.

2016 Hottest Year On Record

Why Double Glazing? 2016 Was The Hottest Year On Record!

 

Using double glazing to  help cool your home is becoming more valuable by the year.

2016 is now officially the world’s hottest year on record. Just ask NASA and NOAA. It beat the previous record, which was set in 2015. Which beat the previous record, set in 2014. See a pattern here?

It’s a sobering thought, but anyone under the age of forty has never lived in a year that was not above the average temperature experienced over the whole of the 20th. Century.

As our summer temperatures get progressively hotter, it has a direct effect on our homes.

  • Hotter temperatures make us more uncomfortable.
  • Hotter temperatures mean that we use our air conditioning more, driving up our electricity bills- at a time when our tariffs are at a record high level, too.
  • The extra hours that your aircon runs, and extra on/off cycling, cuts down the life of your system, and increases the need for maintenance/servicing.

Fitting double glazed windows and doors to your home helps cut down the amount of heat entering in summer. If you also specify uPVC frames, you’ll get the very best combination of high thermal insulation, high acoustic insulation, and a long, maintenance-free lifetime.

Climate Change: More Heatwaves & Double Glazing

Australia can expect more and longer heatwaves due to climate change.

Study: Heatwaves Will Get Longer, Hotter & More Frequent

The evidence is in… again. The University of NSW has used a database that tracks the last 50 or so years of heatwaves , to discover any trends.

Their analysis shows that heatwaves are getting longer, more frequent and more intense in Australia. One of the climate scientists involved in the study, Dr Sarah Perkins-Kirkpatrick explains how and why in the video below. She also reflects on the value of using double glazing to reduce heat inside the home, and reduce air conditioner use. In an ABC 7:30 Report aired on 20/11/2015, one of the climate scientists involved in the study, Dr Sarah Perkins-Kirkpatrick explains how and why. The Interviewer is Julia Baird.

“JULIA BAIRD: And given that emissions are going to increase, obviously there is a debate about to what extent, are we at the point where we need a cultural change, a change in our thinking, where we all start to say okay instead of toughing it out this summer, instead of perhaps buying more air conditioners, we actually try to adapt to it and accept that our lives will be different now?

SARAH PERKINS-KIRKPATRICK: Absolutely I think we needed that about 10 years ago. People sometimes think that double glazing on their windows on their houses for example isn’t a good move because you only need that in cold climates to keep the heat in but insulation goes both ways, if you want to keep the heat in, you also want to keep the cool in and vice versa. So perhaps using those sorts of measures when we are building our houses, maybe making it easier, or cheaper for people to buy those sorts of resources.

That also goes for insulation in the walls of the house, in your roof, making these resources more available. So that goes into our architecture or how we live our daily lives. There are also other ways like maybe the times of days that we move, like it is peak hour out there now, I’m sure a lot of people don’t want to be out there in this hot weather. Perhaps if we moved at different times or could potentially work at home to stop people being out in this extreme weather and getting heat stroke as well. But I would say we needed those changes and that cultural shift to start quite a while ago.”

I couldn’t agree more. We shouldn’t need to point out that double glazing is insulation. and it works both ways. It’s nice to have a scientist remind us that double glazing helps keep us cooler in summer, as well as warmer in winter.
