Kingspan AIR-CELL Insulbreak 70 – Advanced Thermal Break, Insulation & Vapour Barrier in One

Kingspan AIR-CELL Insulbreak 70 is a premium-grade reflective insulation that functions as an insulation layer, a thermal break, and a Class 1 vapour barrier — all in one efficient product. With a nominal thickness of 8mm, it offers increased thermal performance compared to Insulbreak 55, making it ideal for high-spec steel-framed buildings.

Whether you’re insulating walls or roofing systems, Insulbreak 70 helps prevent thermal bridging, controls condensation, and improves energy efficiency across your project.

Thicker Core for Greater Thermal Resistance

Insulbreak 70 features a denser, thicker core that delivers improved R-values. Therefore, it’s an excellent option when you need higher energy efficiency or want to exceed NCC thermal break requirements.

Moreover, the additional rigidity makes it easier to install on uneven metal frameworks, supporting a smoother finish.

Lightweight, Durable and Installer-Friendly

Although it’s strong and tear-resistant, Insulbreak 70 remains lightweight and flexible. You can cut it cleanly with a utility knife, which helps speed up installation. Because it’s non-fibrous and non-toxic, installers can handle it safely without gloves or masks.

Furthermore, it reduces waste on-site due to its clean handling and minimal mess.

Combines Moisture Control with Radiant Heat Protection

In addition to its insulation value, Insulbreak 70 provides a Class 1 vapour barrier. This helps control internal moisture movement, especially in roof and wall cavities. As a result, you lower the risk of mould, water damage, or corrosion inside the structure.

Meanwhile, the reflective foil surface significantly reduces radiant heat gain under metal roofing. This makes it ideal for hot Australian climates where solar exposure is intense.

Integrates Seamlessly with Kingspan Systems

Insulbreak 70 works perfectly with other Kingspan products — including Kooltherm K12 for walls and Permicav XV for cavity applications. Therefore, you can build a complete insulation envelope with consistent thermal performance throughout.

In addition, using a single system simplifies installation and helps ensure compliance with NCC/BCA energy standards.
