ENERGY EFFICIENCY

Windows and glass doors are complex and interesting features in a home or building. They let in light and fresh air and offer views that connect interior living spaces with the outdoors. However, windows and glass doors can be a major source of unwanted heat gain in summer and significant heat loss in winter.

A standard 3mm single glazed window or door has poor insulation qualities, with up to 70% of inside heat being gained (in the summer) or lost (in the winter) through a single glazed unit.   The poor energy efficiency of 3mm single glazed windows and glass doors has resulted in them being banned in many other countries.

Double glazed windows and double glazed doors are very energy efficient, as they reduce the amount of heat lost and heat gained which reduces your need for the use of heating and cooling appliances such as reverse cycle air conditioners.

The Hi Style double glazed range is Window Energy Rating Scheme (WERS) rated for energy efficiency. The WERS scheme allows windows to be rated and labelled for their annual energy impact on a whole house, in any climate of Australia. The scheme forms part of the quality assurance that smart manufacturers offer their customers. It is all about certified performance.

To participate in WERS, window makers must obtain energy ratings for their products from a rating organisation that is accredited by the Australian Fenestration Rating Council. The Window Energy Rating Scheme is managed by the Australian Window Association (AWA).

Hi Style Windows, is a member of this association. WERS-rated windows meet all relevant Australian standards.

If you’re renovating or building paying the extra for double glazed windows and doors, will make the areas where you and your family spend a lot of time more comfortable and help prevent those hot and cold spots near windows and doors.

The thermal efficiency of double glazing comes from a gap between the two pieces of glass filled with Argon gas for maximum performance. The greater the gap the better the performance.

Energy efficient windows and doors make your home more comfortable, dramatically reduce your energy costs and help create a brighter, cleaner, and healthier environment.

If you are renovating or building, your windows may require an energy rating. Your supplier should ensure that the U-value supplied matches the required U-value stated on the energy rating.

Remember the lower the U-value, the better.
