Thermal Break DesignHelping Homes Meet BASIX and NatHERS Energy Standards

In Australia’s residential construction, energy efficiency and sustainability have become core priorities. Particularly in New South Wales and the ACT, the BASIX (Building Sustainability Index) and NatHERS (Nationwide House Energy Rating Scheme) are the key certifications that determine a building’s environmental performance.

Among all structural components, windows and doors play a crucial role in achieving compliance.

M&C Windows & Doors specializes in providing AS2047-certified, high-performance window and door systems for the Australian market.

By using double or triple Low-E (low-emissivity) glass combined with thermally broken aluminum profiles, our systems achieve superior insulation, significantly reducing energy loss and improving a home’s overall NatHERS star rating — helping both developers and homeowners easily meet BASIX and NatHERS energy targets.

The Science Behind Low-E Glass

Low-E glass is coated with a microscopically thin metal oxide layer that reflects infrared heat while allowing natural light to pass through.

This means in the hot Australian summer, it minimizes unwanted heat gain; during winter, it reflects indoor heat back into the room, maintaining a stable and comfortable indoor temperature.

Together with our thermal break structure, the overall U-value (thermal transmittance) and SHGC (solar heat gain coefficient) meet or exceed BASIX and NatHERS energy benchmarks.

Tailored for Australia’s Diverse Climates

Australia’s climate varies greatly — Sydney’s coastal humidity, Melbourne’s fluctuating temperatures, and Brisbane’s intense sunlight each require different performance solutions.

M&C designs each system to suit the local environment, optimizing glass thickness, profile configuration, and sealing systems to achieve the best balance between comfort and energy efficiency.

Factory-Direct Quality, Local Support

As an AS2047-certified source factory, M&C provides not only manufacturing and export but also on-site support for local installation.

From design consultation and energy simulations to delivery and commissioning, we ensure every step aligns with Australian standards — bringing lasting comfort and value to your property.

Energy efficiency is the future of housing.
