Additionally, the passive condensation management promotes healthier indoor air quality. We’d recommend ATI to any builder focused on quality and efficiency.”

Ross Head, Owner

Home Owner Experience

“After a quick Google search, I came across Australian Thermal Industries (ATI) while researching thermal break and wall cavity options for my new home.

ATI provided exceptional support, giving me all the details I needed to persuade my builder to choose ATI’s Cavi-Vent batten over inferior alternatives.”

“For us, it’s a no brainer. We’ll definitely be using the ATI Cavi-Strip in more projects. It’s just so simple and easy to use and cost effective, so it’s definitely the product we’ll be using ongoing.”

Justin Brooks, Director

WST Building & Construction

“I decided to go with ATI Cavi-Break® and let me tell you, the customer service I received was second to none. What’s more, it was competitively priced, even beating the competition who had a far less superior product.”

“Installation was a breeze, especially because there was no need for any power tools. I was surprised at how quickly the strips went up, ready to install the cladding.”

Sam Payling, Director

Coco L Construction

“It was price efficient but also really labour efficient, which should attract many commercial builders on the market.

Other products require additional labour during the attachment, such as fibre cement battens, because you have to screw them on and measure and make sure it’s all right.”

Zach, Project Manager
