Sunlight streaming through energy-efficient windows

Energy Efficiency

Create Your Energy-Efficient Home

Up to 40% of your home's heating and cooling load is lost through windows and doors. Upgrade to double or triple glazing and feel the difference from day one.

The Science

How Double & Triple Glazing Saves Energy

Heat moves through single glazing almost unimpeded, conducting through the glass and radiating from the inner surface. Double and triple glazing create sealed cavities that trap still air or noble gas, dramatically slowing this transfer in both directions.

In Perth's climate, this works both ways: keeping summer heat outside in January, and keeping your heated air inside during cooler months. The result is a home that requires far less air conditioning and heating to stay comfortable.

Lower U-Value = Less Heat Transfer

Our double glazed units achieve U-values from 1.0 W/m²K; triple from 0.6 W/m²K, compared to 5.8 W/m²K for single glazing.

Low-E Controls Solar Heat Gain

Different Low-E coatings can be specified to either block solar gain (west-facing windows) or allow it (north-facing in winter), the right SHGC for your orientation.

NatHERS Star Rating Improvement

Upgrading from single to double glazing can improve a home's NatHERS rating by 1–2 stars, a significant improvement for resale value and rental yield.

Our Tiers

Regular vs High Performance

Both deliver a massive improvement over standard windows. Your choice depends on noise levels, climate zone and sustainability goals.

Regular

Double Glazing + Low-E + Argon

  • U-value from 1.0 W/m²K
  • Rw 32–38 acoustic performance
  • Warm-edge spacer bars
  • Dramatically better than any single-glazed product
  • Available in uPVC or aluminium
Recommended

High Performance

Triple Glazing + Acoustic Glass + Krypton

  • U-value from 0.6 W/m²K, passive house
  • Rw up to 53 dB noise reduction
  • Laminated acoustic inner pane
  • Krypton gas fill for thinner units
  • Maximum NatHERS star contribution
