75mm Kingspan Kooltherm K108 features a low emissivity composite foil facing that is firmly adhered to the insulation core at manufacture. This reflective layer significantly boosts thermal resistance in unventilated cavities adjacent to the board.
The 75mm Kingspan Kooltherm core comprises a premium performance fibre-free rigid thermoset phenolic material, manufactured using a blowing agent with zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP).
