Kingspan K106 Cavity Board

Kingspan Kooltherm K106 is a premium performance, rigid thermoset phenolic insulation board for application within cavity walls with a residual 10mm cavity. Kooltherm K106 is faced on one side with a vapour-open polypropylene fleece, which is bonded to the phenolic insulation core during manufacture and protects against moisture penetration, and on the other side with a low emissivity composite foil. The core itself offers unrivalled thermal performance with its thermal conductivity of o.o18W/m2K.

Kingspan K106 insulation is made of high-quality phenolic foam. It’s CFC and HCFC free and has an ozone depletion potential of zero. Its environmental impact is therefore very low for a foam insulation material.

K106 insulation boards should be installed in accordance with the manufacturer’s installation guidelines – these should cover design and all aspects of the application of the insulation. Kingspan Kooltherm K106 is usually held in position by the wall ties used to tie the two skins of masonry together.
