What is the thermal conductivity of Gyproc ThermaLine laminates?

Our Gyproc ThermaLine laminates comprise of Gyproc WallBoard (thermal conductivity 0.19 W/mK) and rigid foam insulation (thermal conductivity ranges from 0.02 to 0.04 W/mK depending on type). Therefore we do not quote a composite thermal conductivity value but do quote a composite thermal resistance value (m2 K/W).
