uPVC Windows
The Energy Efficient Solution
uPVC Windows can dramatically improve the energy efficiency for your home.
The low conductivity of uPVC as a material, the tight seals uPVC windows provide and the ease with which they can be fabricated for double and triple glazing, make uPVC an excellent choice in energy efficient buildings.
PVC is a natural insulator and doesn’t easily transfer heat from inside to outside, or outside to inside. Next time you are near an aluminium framed window, put your hand on the frame and feel its temperature.
uPVC is the material most widely used for windows across Europe and North America where the focus on energy efficient buildings began decades ago.
Up to 70% of heat is gained or lost through standard 3mm window panes and even more is lost with heat transfer through metal frames. In winter, a single-glazed, 3mm-deep pane of glass can lose from ten to 15 times more heat than an insulated wall of the same area. In summer, single glaze standard windows of an average home account for over 25% of total heat gain.
The rate of transfer of heat, or thermal transmittance, is also known as U-value. A high U value results in rapid gain or loss of internal heat to or from the ambient external environment, increased heating and cooling bills, and poorer occupant comfort.
Double glazing your windows reduces thermal transmittance which can be further enhanced by selection of high performance uPVC frames.
It’s a simple goal in modern-day home life ... keep cool in the summer and warm in the winter.
Keeping warm in winter: By cutting the transfer of heat from the warm inside to the cold exterior, uPVC windows will significantly reduce loss of heating warmth in cold weather and reduce the energy required to heat interior spaces.
Keeping cool in summer: Cooling a home in summer can use up to three times more energy than required to heat it in winter. Installing double-glazed uPVC window frames can keep you cooler in summer by reducing solar heat gain from outside. And in the evenings, openable Tilt and Turn window systems allows you to take advantage of natural cross ventilation to cool the home.
Australian windows are rated for energy efficiency by the Window Energy Rating Scheme (WERS). In Australia, uPVC windows consistently rate among the highest performers under the WERS and significantly outperform most aluminium windows.
They are proven performers in reducing energy consumption for heating and cooling and consequently, over their whole life cycle, can reduce greenhouse gas emissions by as much as 48-61% compared with aluminium framed windows*.
Using double glazed uPVC windows will therefore make a valuable contribution to lowering Australia's greenhouse emissions and lower your energy bills!
