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.
