What Is 60mm Kingspan Kooltherm K5 External Wall Board?
Kingspan Kooltherm K5 is a high-performance insulation board designed for use on external masonry walls. It’s made with a fibre-free phenolic core and finished with glass tissue on both sides. The board is suitable for installation behind lightweight render systems and dry cladding and is built to resist the movement of water vapour through the wall system.
Measuring 1200mm by 600mm, the boards are manageable on site and easier to install, especially when compared to some other commonly used insulants. Each board has a thermal conductivity of 0.021 W/mK, offering excellent insulation performance in a slim profile.
60mm K5 is typically used on masonry walls, which are built using blocks, bricks, or stones laid in mortar. When fitted as part of a full external wall insulation system (usually with a polymer-modified render) K5 helps reduce heat loss through the building envelope.
Kingspan manufactures Kooltherm K5 under a management system certified to ISO 14001:2015, and its compressive strength exceeds 100 kPa at 10% compression.
Phenolic Core
At the heart of each board is Kingspan’s rigid phenolic core. This material doesn’t contain fibres and is laminated on both sides with glass tissue. Among commonly used insulation materials, phenolic foam stands out for its thermal efficiency.
The 70mm Kooltherm K5 board has a thermal conductivity of 0.021 W/mK, which means it slows down heat transfer more effectively than many alternatives. That’s one of the reasons phenolic insulation is often used where high performance is needed in a limited space.
Phenolic insulation has the lowest thermal conductivity rating of all commonly used insulation materials.
Available Thicknesses
Kooltherm K5 boards are sold in a range of sizes, with 50mm, 60mm and 70mm thicknesses available.
This allows specifiers and installers to choose a thickness that meets thermal targets without overbuilding. It also makes it easier to match existing build-ups when retrofitting or replacing sections of wall.
