Aluminium Windows and Doors

What Are Thermally Broken Windows and Doors?

Thermally broken windows and doors feature a polyamide strip between the inside and outside aluminium frames, creating a barrier that prevents the transfer of thermal energy. This cutting-edge technology enhances energy efficiency by reducing heat loss or gain, making it ideal for eco-friendly construction and properties focused on sustainability. The ACA thermally broken range offers not only comfort but also a luxurious, energy-saving alternative to traditional aluminium systems.

The Perfect Solution for Modern Living

Our thermally broken aluminium systems provide the following key benefits:

Comprehensive Range: Available in a variety of windows, doors, and commercial frames to suit any project.
Energy Efficiency: Designed to maximize energy savings and reduce reliance on artificial heating and cooling.
Custom Engineered: Tailored to withstand the unique challenges of the Australian climate.
Thermal & Acoustic Insulation: State-of-the-art technology ensures superior insulation against temperature fluctuations and noise.
Durable and Stylish: Available in a wide range of powder-coat colours, combining durability with aesthetic appeal.

Performance and Testing

Meeting Australian Standards for Energy Efficiency

In today’s green building landscape, energy efficiency is a priority. ACA’s thermally broken window and door systems are designed to meet Australia’s strict AS2047 and AS4284 standards for performance, including tests for wind resistance, water penetration, and structural integrity. These systems are rigorously tested to ensure they deliver superior insulation, especially when paired with high-performance glass that blocks solar heat.

Tested to AS2047

A lower U-value means better insulation. ACA’s systems are designed to reduce heat transfer, helping you maintain a comfortable indoor environment year-round.

SHGC Ratings

The Solar Heat Gain Coefficient (SHGC) measures the window’s ability to block solar heat. With optimized SHGC ratings, our systems help limit heat absorption, making them ideal for Australian summers.

Advanced Thermal Break Technology

Engineered for Maximum Efficiency

The key to our thermally broken systems’ superior performance lies in their innovative design. Our windows and doors use dual aluminium profiles with a polyamide strip between the internal and external components, creating a thermal barrier that prevents unwanted heat transfer. This design reduces the need for additional heating or cooling, making these systems a smart, energy-efficient choice for both homes and commercial buildings.

Design Flexibility and Performance

Customizable Solutions for Every Project

Our thermally broken windows and doors are not just about performance—they also offer design flexibility for architects and builders. These systems allow for large sections of glass without compromising energy efficiency, making them perfect for projects that prioritize natural light, ventilation, and panoramic views. With ACA’s range of custom solutions, your design options remain limitless, without sacrificing performance or compliance with Section J energy regulations.

Acoustic Insulation

Quiet Comfort, Even in Noisy Environments

The multi-cavity design of ACA’s thermally broken systems, combined with high-performance insulating glass, significantly reduces noise levels, creating a peaceful indoor environment. These systems can bring outdoor noise down to as low as 24dB, even in busy urban areas where external noise levels reach up to 60dB.
