Energy Efficiency

Reducing energy consumption in every aspect of our lives is high on the national agenda. The federal government has developed mandatory minimum energy efficiency measures. Selection and placement of glazing is one of the most critical elements in designing for energy efficiency.

The key focus is on minimising the rate of summertime heat gain and winter heat loss.

Glazing performance is measured in terms of U-value (for conduction) and solar heat gain coefficient (SHGC), and is based on the National Fenestration Rating Council (NFRC) conditions.

Window and door energy efficiency is the product of the framing quality, selected glass, and the installation method. The combination of these elements all contribute to the successful insulation of your home.

Our architectural range of windows and doors has been tested to comply with AS2047-1999 at the strictest commercial criteria. Additional to this they have also been tested to comply with the Window Energy Rating Scheme (WERS) requirements.

The major factors of insulation in windows and doors are both the U-Value and the SHGC.

  • U-Value - The insulation value of the frame and glass or the ability to keep heat in.
  • SHGC (Solar Heat Gain Co-efficient) - The measure of solar heat that can travel through to the inside of your home.
