What Is 70mm Kingspan Kooltherm K107 Board?
70mm Kingspan Kooltherm K107 Board is a premium thermal performance insulation designed specifically for pitched roof applications - ideal for both new build and refurbishment projects.
It has a rigid, fibre‑free thermoset phenolic core and achieves a thermal conductivity of 0.019 W/mK across all thicknesses, placing it among the most thermally efficient commonly used insulation products.
Applications
70mm Kingspan Kooltherm K107 is engineered for use in warm roof constructions - installed between rafters in tiled or slated pitched roof spaces.
It supports compliance with modern building regulations where high insulation performance is required.
Benefits
- Premium thermal performance (0.019 W/mK)
- Fibre‑free phenolic core, rigid yet lightweight
- Foil facings on both sides
- Easy to handle and install, compared to some other commonly used insulants
Weather Resistance and Moisture Control
70mm Kooltherm K107 Board features composite foil facings on both sides. These layers work to hold in heat and limit moisture from moving through the roof, while still allowing the space to remain breathable - protecting the insulation's condition in the long term.
Installation Guidance
70mm Kingspan Kooltherm K107 boards are supplied in standard panels measuring 2400 mm x 1200 mm. They can be trimmed by hand using a utility knife and hand saw.
Appropriate safety gear, such as goggles and gloves, is recommended.
Performance Standards for K107
Kingspan Kooltherm K107 boards are manufactured under certified management systems:
- ISO 9001: 2015 - Quality Management
- ISO 14001: 2015 - Environmental Management
- ISO 45001: 2018 - Health & Safety
- ISO 50001: 2018 - Energy Management
This ensures stable performance in pitched roof installations under normal conditions.
