90mm Kingspan Kooltherm K106 Cavity Insulation Board 1200mm x 450mm (2.16m2/Pack)

Kingspan Kooltherm K106 Cavity Insulation Board with a 90mm thickness. This rigid phenolic insulation board is designed for partial-fill masonry cavity walls. It incorporates a fibre-free rigid thermoset phenolic core with a low-emissivity composite foil on one face and a water-tight, vapour-open polypropylene fleece on the other to manage moisture exposure within cavity constructions. The board maintains a 10mm residual cavity to protect against moisture penetration while delivering high thermal efficiency in masonry wall elements. Its lightweight, rigid construction supports easy handling and placement during brickwork progression. The 90mm board is suited to cavity wall designs requiring substantial insulation depth to achieve enhanced thermal performance targets.
