My husband and I cannot fault the service we received from design studio consultant Megan at the Central Coast showroom. She was so friendly throughout our initial emails, and couldn’t be more informative when I visited the showroom itself. I had been gathering multiple quotes from other local window suppliers and Megan really stood out from the rest.

What is Thermal Break?
Bradnam’s thermal break products are expertly designed to ensure the utmost resistance to heat transfer – using reinforced polyamide extrusions and double glazing with warm edge spacers as barriers to thermal conduction. This advanced technology effectively minimises heat and cold exchange through the windows and door frames, keeping the home cooler in summer, and warm in winter.
The most energy efficient solution available, Bradnam’s thermal break range ensures year-round comfort, reduced energy costs, and exceptional insulation performance. Whether you’re designing for a modern home or a high-performance commercial space, Bradnam’s thermal break systems deliver cutting-edge designs that don’t compromise on thermal performance.
Why choose Thermal Break?
Protecting the home from extreme temperatures, Bradnam’s thermal break windows and doors deliver superior insulation and energy efficiency, creating a more comfortable indoor environment while reducing reliance on artificial heating and cooling.

High-performance Thermal Break
When selecting energy-efficient windows and doors, two key factors matter most – U-value, and design. A lower U-value means stronger insulation and resistance to heat transfer, while a design that’s configured for optimised thermal performance enhances comfort and efficiency – reducing energy use and lowering electricity costs year-round.
