100mm Kingspan Kooltherm K108 Cavity Insulation Board 1200mm x 450mm (2.7m2/Pack)

Kingspan Kooltherm K108 Cavity Insulation Board with a 100mm thickness. This rigid phenolic insulation board is designed for partial-fill masonry cavity wall applications. It features a fibre-free rigid thermoset phenolic core faced on both sides with low-emissivity composite foil to improve thermal resistance within the cavity. The board assists in maintaining a clear cavity to resist moisture penetration while supporting efficient thermal performance in masonry wall designs. Its lightweight, rigid construction aids straightforward handling and secure retention using standard wall ties during the progression of brickwork. The 100mm board is suited to cavity wall constructions requiring maximum insulation depth within partial-fill designs to meet high-performance thermal targets.
