The radiant barrier is installed beneath the roof covering (roof tiles or fibre cement sheeting), laid over wooden battens or purlins with a 150 mm overlap at all joins, and secured with staples. It sits between the roof covering and the rafters, creating an effective thermal barrier that reflects radiant heat away from the building interior.
