Description
Kingspan Kooltherm K12 Insulation – Premium Wall Insulation Made to Perform
Kingspan Kooltherm K12 Insulation is a high-performance range of rigid phenolic boards designed for use in external timber and steel wall systems. Thanks to its advanced thermoset core, the K12 series delivers ultra-low thermal conductivity — as low as 0.022 W/m·K to 0.023 W/m·K .
Because of this, you can achieve higher energy efficiency without increasing wall thickness. Whether you’re building new or upgrading an existing structure, K12 offers a smart and space-saving solution.
Multiple Thicknesses for Flexible Insulation Design
The Kooltherm K12 range is available in 25mm, 30mm, 40mm, 50mm and 60mm variants. This wide selection allows you to match the board thickness to your project’s energy goals and wall structure. Additionally, it ensures that both residential and commercial applications can benefit from the same trusted performance.
Moreover, each board maintains its rigidity during installation, resulting in a snug fit and improved airtightness.
Quick to Install, Built to Last
Installing Kingspan Kooltherm K12 Insulation is straightforward. The boards are lightweight, easy to cut, and simple to position. As a result, builders can work more efficiently, saving both time and labour costs.
Furthermore, the phenolic core resists moisture, which protects long-term thermal performance. This makes K12 a reliable option for Australia’s varied climate conditions.
Works Seamlessly with Other Kingspan Kooltherm Boards
In addition to wall insulation, Kingspan offers Kooltherm K3 Floorboard and Kooltherm K10 Soffit Board. These compatible products allow you to create a complete insulation system across floors, walls, and ceilings. Therefore, your entire building envelope benefits from consistent high performance.
Choosing a full Kingspan system can also simplify compliance with NCC/BCA requirements.
