Suitable for a variety of pitched roof applications, Kingspan Kooltherm K107 offers outstanding performance and easy retrofitting, making it ideal for attic floors and flat ceilings. With a fibre-free rigid thermoset phenolic core, the Kooltherm K107 is perfect for insulating warm roof spaces in either ventilated or unventilated pitched roofs, under slates or tiles.  

K107’s superior thermal conductivity at 0.019 W/mK allows for a thinner installation while achieving target U-Values, replacing Kingspan Kooltherm K7. The low emissivity foil outer facings enhance thermal resistance, optimising energy efficiency. These Kooltherm K107 pitched roof boards are easy to handle and easy to cut to suit rafter spacings for an efficient installation process. Kingspan K107 also helps to eliminate cold bridging through roof timbers.
