Kooltherm K8 Cavity Board

Kooltherm K8 Cavity Board Product Wedge

Rigid Cavity Wall Insulation

Kingspan Kooltherm K8 Cavity Board is a high performance, fibre-free rigid insulation suitable for cavity wall applications. It has a thermoset phenolic insulation core, sandwiched between two layers of reflective, low emissivity composite foil autohesively bonded to the insulation core during manufacture. This reflective, low emissivity surface improves the thermal resistance of any cavity adjacent to the board.

  • Made in Australia
  • Clear cavity is maintained
  • CodeMark-certified for NCC compliance
  • CFCs/HCFCs free, zero Ozone Depleting Potential (ODP), and low Global Warming Potential (GWP)

Assumption and Key

The R-values shown are Total R-values for the building element as required by the Energy Provisions of the Building Code of Australia. Kingspan Kooltherm products are manufactured, tested and packaged in conformance with AS/NZS 4859.1.

The contribution of the product Total R-values depends on installation and environmental conditions. The R-value will be reduced in the event of the accumulation of dust on the upward facing surfaces and in those cavities that are ventilated.
