Kingspan K108 Insulation is a premium performance cavity wall insulation for use in a partial cavity wall insulation construction. Kooltherm K108 insulation has a super low thermal conductivity of 0.018 W/m-K. Having a higher grade of insulation in the cavity allows for a thinner insulation to be used on the interior of the construction. Therefore giving a greater available living space. Being a partial fill cavity insulation it leaves a clear cavity space and resists moisture penetration. Kingspan K108 insulation is a lightweight easy to handle insulation material and is easy to install. This high performance board when used at 120mm thickness and with aerated blocks can achieve ‘U’ Values as low as 0.12 W/m-K.
