New building regulations require houses to be energy rated. Windows are a major factor when designing a house and meeting the strict compliance requirements, for example; a window on a south facing wall with standard glass will rate very poorly, bringing the overall energy rating of the house down by a considerable amount.

Using ECOadvantage double glazed windows will greatly reduce heat loss in winter and heat transfer in summer, and therefore help achieve the rating reqired.

This means a truly comfortable home all year round and massive dollar savings on energy bills.

Window Energy Rating Scheme - (WERS).

WERS is an energy performance rating sceme that ranks residential windows on a scale of 1-5 depending on their anual energy performance, the star rating that a window recieves depends on how much annual heating energy needs to be added to a house, and the amount of annual cooling energy that must be used to keep the house within a comfortable temperature range.

This generates star ratings for cooling and heating.

WERS conveys information about the window on three levels:

• Star ratings for heating and cooling
• Indicative % reduction in heating and cooling needs
• Thermal, solar and optical performance data

The Aspect Windows ECOadvantage range of windows have achived fantastic NATA test results. By using ECOadvantage windows in your home coupled with innovative glazing options you can expect a reduction in heat transfer through your windows by over 55%. This translates as direct savings on energy bills, less impact on the environment and the achievment of a more comfotable home.

The eco advantage range can achive a Uvalue as low as 1.4 and a SHGC value of less than .25.
