With a thermal conductivity of just 0.018 W/m.K, the Kingspan Kooltherm packer board helps to minimise the overall system thickness required to achieve a desired U–value.
Typical thickness savings of 20 - 40 mm could be achieved, dependent on the individual scheme and build-up, when compared with a full Polyisocyanurate (PIR) system.
The lightweight boards are easy to handle and are fitted with a dry installation process. This can greatly reduce project timescales when compared with wet approaches such as screed to fall which can take 195 days, or more, to dry. In refurbishment applications, they can typically be installed above the existing roof surface (with a waterproof membrane), avoiding the time–consuming process of stripping the existing roof.
