60mm Kingspan Kooltherm K107 Pitched Roof Insulation Board 2400mm x 1200mm (5/Pack)

Kingspan Kooltherm K107 Pitched Roof Insulation Board in a 60mm thickness provides premium thermal performance for tiled or slated pitched warm roof constructions. The fibre-free phenolic core achieves a low thermal conductivity of 0.018 W/m·K, supporting strong energy control within rafter-level and joist-level pitched roof systems. Both faces of the board are finished with a low-emissivity composite foil, enhancing thermal performance when installed adjacent to an air space. Its closed-cell phenolic structure remains unaffected by air infiltration and resists the passage of water vapour, maintaining stable performance within the roof build-up. A lightweight design allows efficient handling, accurate cutting, and straightforward installation across both new-build and refurbishment projects. The material is non-deleterious and manufactured using a zero-ODP, low-GWP blowing agent for responsible specification. The board supports improved thermal detailing around rafters and junctions, contributing to reduced heat loss in warm roof assemblies. Certification under responsible-sourcing standards ensures suitability for modern, low-energy construction practices. Manufactured with a 60mm thickness, it provides a balanced insulation option suited to warm roofs requiring increased thermal resistance.
