  • Cavi-Vent®, applied horizontally, acts as a thermal break, ventilated cavity drainage batten and cavity closer

They can be used for all types of lightweight cladding and provide a quadruple function

  • thermal break strip for improved thermal performance
  • cavity batten to create a 20mm cavity
  • cavity drainage and cavity ventilation for condensation management
  • cavity closer

This integration improves thermal performance and building health, making it a leading choice for modern construction needs.

Thermal Performance

A superior, economical thermal break strip

ATI’s Cavi-Break® and Cavi-Vent® Strips are advanced thermal break and condensation management solutions, exceeding National Construction Code (NCC) standards with an R-value of 0.58 m² K/W—nearly three times the minimum requirement of 0.2 m² K/W.

In both steel and timber frame applications, the Cavi-Break and Cavi-Vent Strips provide an advanced thermal barrier between external cladding and the frame, significantly reducing thermal bridging. Additionally, they manage condensation, mitigating risks of rot, mildew, and mould to support healthier, more durable homes.

Customer Stories

Lifestyle Cabins unpluggedd

“ATI’s products have simplified our tiny home construction process. The self-adhesive design streamlines installation, reducing noise and dust on-site

With an approximate 25% boost in thermal efficiency across the wall envelope, we can offer long-term energy savings for our customers.

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

Brooks Builders

“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

Integrity New Homes Brisbane

“During our trial of the product we utilised the Cavi-Break Strips on the neighbouring build as they were so easy to handle, had great self-adhesive and saved time.”
