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 doesn't conduct heat well therefore doesn't transfer temperatures 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 the US where the focus on energy efficient buildings began around 30 years 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.
Double glazing your windows is said to improve thermal resistance by 94%. The air pocket created between the two glass panes provides an insulating barrier, keeping the outside heat out and regulating your interior temperature.
Installing new double-glazed units is recommended when you are doing a major renovation and/or extension and are looking for a high quality, well-sealed product.
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 side of the window, 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 the energy 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, the openable Tilt and Turn window system allows you to take advantage of natural cross ventilation to cool the home.
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 India's greenhouse emissions and lower your energy bills!
