Achieve excellent thermal performance with this 100mm PIR Foil Faced Insulation Board, a versatile rigid insulation board suitable for walls, floors and roofing applications. Measuring 2400mm x 1200mm, it provides substantial insulation performance for residential, commercial and general construction projects. The high-performance PIR core offers excellent thermal resistance while maintaining a practical board thickness, helping to reduce heat transfer through the building envelope. Its 100mm thickness makes it particularly suitable for projects requiring higher levels of insulation, including new builds, extensions and energy-efficiency upgrades. Foil facings provide a durable finish to both sides of the board, while the lightweight rigid construction makes handling, measuring and cutting straightforward on site. Boards can be fitted accurately to help minimise gaps and maintain consistent insulation coverage throughout the installation.
