ThermalHEART™ Energy Efficient Windows & Doors – How It Works

ThermalHEART™ is an innovative thermal break technology integrated into the aluminium frame. Here’s what makes it different:

• A non-conductive polyamide strip is inserted between the inner and outer aluminium frame sections
• This break interrupts the transfer of heat and cold through the frame itself
• The result is a frame that performs closer to timber or uPVC in thermal efficiency, while retaining all the strength and durability of aluminium
• Significantly reduces condensation on interior frame surfaces
• Compatible with double and triple glazing for maximum performance
• Suitable for both residential and commercial applications

ThermalHEART™ aluminium windows and doors are an ideal solution for Melbourne homes seeking to meet or exceed the National Construction Code (NCC) energy efficiency requirements. They are up to 51% more thermally efficient than standard non-thermally broken aluminium framing.

The Role of Windows & Doors in Energy Efficiency

Windows and doors are among the greatest sources of heat gain and heat loss in any building. In fact, poorly performing windows can account for up to 40% of a home’s heating energy loss and almost 90% of heat gain in summer.

Choosing energy efficient windows in Melbourne is one of the most effective ways to:

• Reduce unwanted heat entering your home in summer
• Retain warmth inside during Melbourne’s cold winters
• Lower your reliance on air conditioning and heating systems
• Decrease your household energy bills year-round
• Improve the overall comfort of your living or working environment
• Reduce your building’s carbon footprint

Upgrading to thermally efficient aluminium windows and doors is a long-term investment that pays dividends in comfort, cost savings, and sustainability.

How Is a Window’s Energy Efficiency Measured?

When evaluating energy efficient windows in Melbourne, there are several key performance metrics to understand:

• U-Value (Thermal Transmittance) Measures how much heat passes through the window. A lower U-value means better insulation and less heat loss in winter.
• Solar Heat Gain Coefficient (SHGC) Measures how much solar heat passes through the glass. A lower SHGC reduces heat gain in summer, which is important for Melbourne’s warm seasons.
• Visible Light Transmittance (VLT) The percentage of visible light that passes through the glass. Higher VLT means more natural light inside your space.
• Star Ratings Windows in Australia are rated under the WERS (Window Energy Rating Scheme). Higher star ratings indicate better overall energy performance for both heating and cooling climates.
• Condensation Resistance Thermally broken frames significantly reduce the risk of condensation forming on interior frame surfaces, improving comfort and preventing moisture damage.

Why You Should Choose Energy Efficient Windows and Doors

Investing in energy efficient windows and doors in Melbourne delivers benefits well beyond your energy bill:

Lower Energy Costs

Thermally broken aluminium windows and double glazing reduce heating and cooling demand, delivering measurable savings on your electricity and gas bills over time.

Year-Round Comfort

Maintain a more stable indoor temperature regardless of Melbourne’s unpredictable weather with energy efficient windows and doors. Less heat in summer. Better warmth retention in winter.

Reduced Condensation

ThermalHEART™ frames significantly reduce condensation on interior surfaces, preventing mould, moisture damage, and deterioration of window furnishings.

Acoustic Performance

Double-glazed, thermally broken windows also act as an effective acoustic barrier, reducing outside noise from traffic, neighbours, and urban environments.

Increased Property Value

Energy efficient homes are increasingly sought after in the Melbourne property market. Upgraded windows and doors are a tangible selling point for buyers and tenants alike.

Environmental Responsibility

Reducing your energy consumption lowers your carbon footprint. By investing in energy efficient windows and doors, you contribute to a more sustainable built environment.

NCC Compliance

Our ThermalHEART™ systems help residential and commercial buildings meet or exceed National Construction Code (NCC) energy efficiency requirements.

Frequently Asked Questions About Energy Efficient Windows and Doors in Melbourne

What makes ThermalHEART™ windows more energy efficient than standard aluminium windows?

Standard aluminium frames conduct heat and cold readily, which reduces their thermal performance. ThermalHEART™ frames incorporate a non-conductive polyamide thermal break within the aluminium profile, interrupting this transfer of temperature.

Combined with double glazing and Low-E glass, ThermalHEART™ windows deliver significantly improved insulation compared to conventional aluminium windows.

Why are energy efficient windows worth the investment in Melbourne?

Melbourne’s climate — with hot summers and cool winters — makes thermal performance particularly valuable. Energy efficient windows reduce your reliance on heating and cooling systems year-round, delivering ongoing savings on energy bills. They also improve comfort, reduce condensation, and can increase your property’s value.

Can I retrofit energy efficient windows into my existing Melbourne home?

Yes. Regency Windows can replace your existing windows with ThermalHEART™ energy efficient aluminium windows as part of a renovation or upgrade.

Our team will assess your current openings, advise on the best product configuration, and manage the full installation process with minimal disruption.

Do your energy efficient windows meet Australian Building Standards?

Yes. Our Designer Series with ThermalHEART™ is manufactured in accordance with Australian Building Standards and helps residential and commercial buildings meet National Construction Code (NCC) energy efficiency requirements.
