Cool Climate Zone in VIC, NSW, SA, & ACT
7 Star energy efficiency guide for Vic, NSW, SA and ACT
Under the NCC 2022 energy efficiency provisions, all new homes and building permits issued from May 1st, 2024, need to meet a minimum energy efficiency rating of 7 Stars. Here we’ll help you understand how your windows and doors can help you achieve this, regardless of whether you’re building or renovating. |
Climate Zones in VIC, NSW, SA and ACT
As VIC, NSW, SA and ACT have a heating temperate climate, it's important that your home stay comfortable throughout the year—keeping warm in winter and cool in summer.
To meet the 7 Star energy efficiency standard, one of the most effective strategies is to choose windows and doors with a low U-Value and a low Solar Heat Gain Co-efficient (SHGC). A lower U-Value means better insulation, which helps retain indoor warmth and reduces the need for unwanted heating. The U-Value is a key factor in enhancing thermal performance in these climates.
Achieving greater performance with eX Hybrid
|
Energy efficiency exists on a scale, with cost and design preferences changing what you might choose for your home. eX Hybrid offers a balanced solution, providing sufficient U-Value coverage to achieve 7 Star performance, without the cost of a fully Thermally Broken solution. The below shows our good, better, best options—designed to help you find the right fit for your needs. |
GOODEX HYBRID + DOUBLE GLAZED CLEAR |
The starting point of improved energy efficiency is to upgrade to the eX Hybrid with clear double glazing. The eX combines Thermally Broken technology with Stegbar’s standard frames, which significantly improves thermal performance, but without the price tag of a full Thermally Broken product. |
BETTEREX HYBRID + DOUBLE
|
Take the next step in energy efficient glazing by combining the eX Hybrid with Low Emissivity (Low-E) soft coat glazing. The Low-E coating is applied to the inside of one piece of glass. This coating reduces the amount of heat or cold that is transferred. While it represents a higher initial investment, the combination provides tangible long term benefits in energy efficiency. |
BESTEX HYBRID + DOUBLE GLAZED LOW-E DOUBLE COAT |
Our best performing glass is Double Glazed Low-E Double Coat, using both a Soft and Hard Low-E coating on surfaces 2 and 4 of your glass. These two coatings lower the U-Value even more, while the enhanced eX Hybrid sash or panel helps with compliance in more complex projects. |
SUPERIORENVIRA COLLECTION +
|
Our superior offering is our Envira Collection, available with single or Double Coat Low-E Double Glazing. Providing a range of options to suit the most advanced energy efficiency needs. |
