How energy efficient glass saves you money.
Stay cool in summer and warm in winter - this is what glass can do for you.
Choosing the right 'performance glazing' (energy efficient glass) lets you control how much heat enters or escapes from a building. Let's go through the essentials in understanding how your home's energy flow works.
High performance (energy efficient) windows and glass are critical to a building’s energy efficiency.
With regular windows notorious for unwanted heat loss and heat gain, in most cases they will not be adequate for current home designs to meet increased building regulations.
However, with significant energy star increases available by specifying the appropriate high performance glass and frame combination, there is no need for consumers to limit glazed areas to achieve compliance.
Studies show that a home can achieve an increase of 2 to 2.5 stars by simply going from the worst-performing windows to the best-performing windows.
There is no ‘one size fits all’ solution. No single window can claim to ‘make’ a house achieve 6-star. What works well in Cairns will not necessarily be suited to a home in Hobart.
Even in the same location, two different homes may require different windows to achieve the same star rating.
And even two identical homes, located in the same climate, may require different windows or glass to achieve a given star rating due to their different orientations.
Factors such as customised placement of windows around the building and optimal orientation coming into play.
A common misconception is that high performance windows and glass are an expensive way of increasing energy efficiency. Economic findings address the financial implications of high performance windows more fully, however, it is safe to say that while windows – even ordinary ones – are a relatively high-value component of a building, they make all the difference between a nice (high market value) house and an awful (unsellable) one.
