High-performing windows and doors can make heating or cooling your home simpler and more cost effective, saving money on expensive electricity and gas. Although they are much larger framing systems, Elevate™ window and door systems are WERS-rated and tested to make choosing the right product as simple as possible to deliver comfort and performance in any environment.
To get the highest energy efficiency from your windows and doors, it’s important that they are installed by a qualified professional, and located in the best position to take advantage of natural cross ventilation, light and solar heat gain in both summer and winter.
U-values are the measure of how much heat is transferred through a window or door. The lower the U-value the more efficient it is at keeping the heat or cold out.
SHGC measures how much solar radiation passes through a window or door. In a cool climate, a high SHCG will allow more solar heat to enter your home.
WERS is the Window Energy Rating Scheme for windows and doors in Australia. It uses a 10-star system to rate the annual energy impact on a home, based on its U-value and Solar Heat Gain Coefficient (SHGC). The more stars, the better.
