Kingspan AIR-CELL Insulbreak 90 – Maximum Thermal Break, Vapour Barrier & Reflective Insulation in One Layer

Kingspan AIR-CELL Insulbreak 90 is the thickest and most high-performing option in the Insulbreak range. It combines insulation, a thermal break, and a Class 1 vapour barrier into a single, high-performance solution. With a nominal thickness of 10mm, it delivers superior R-values and greater compliance for steel-framed buildings where energy efficiency is a top priority.

Whether you’re designing high-end residential or commercial steel-frame projects, Insulbreak 90 helps minimise thermal bridging, reduce heat flow, and control moisture — all while simplifying compliance with NCC/BCA Section J.

Exceptional Performance with Extra Thickness

Thanks to its 10mm closed-cell core, Insulbreak 90 offers higher thermal resistance than both Insulbreak 55 and 70. As a result, it’s an ideal choice when targeting low-energy builds, passive design, or strict commercial energy requirements.

Moreover, the thicker profile provides added compressive strength, improving installation on metal battens, purlins, or structural frames.

Designed for Faster, Safer Installation

Insulbreak 90 is non-toxic, fibre-free, and easy to cut. You can trim it on-site using a utility knife and install it directly over framing without special tools or PPE. This not only speeds up labour but also keeps job sites cleaner and more efficient.

In addition, its tear-resistant foil facings provide added durability throughout the construction phase.

Thermal, Vapour and Radiant Heat Control

While Insulbreak 90 excels as a thermal break, it also functions as a Class 1 vapour barrier. This prevents moisture transfer through walls and roofs, protecting insulation performance and reducing the risk of mould.

Furthermore, its highly reflective foil surface deflects radiant heat, making it particularly valuable under metal roofs or sun-exposed façades. Therefore, buildings stay cooler in summer and more stable year-round.

Fully Compatible with Kingspan Systems

Like other AIR-CELL products, Insulbreak 90 integrates seamlessly with Kingspan Kooltherm K12 and AIR-CELL Permicav XV, creating a continuous and compliant building envelope. As a result, you’ll streamline design, installation, and compliance while maximising overall performance.

Using a full Kingspan system also helps ensure consistent R-values throughout all building zones.
