Kooltherm K8 Cavity Wall Insulation Board

K8 Cavity Wall Insulation

Advanced partial fill cavity wall insulation with thermal conductivities as low as 0.020 W/mK

Kooltherm K8 is an advanced cavity wall insulation board with low emissivity foil facings and reaching thermal conductivities of as low as 0.020 W/mK. This means it allows for an extremely thin cavity wall construction, which in turn maximises the usable internal floor space within the building.
