Battens are narrow strips of material that are often made of woods. These elements are used beneath the roof cladding and over the main roof frames to provide a fixing point for roofing materials. Battens create an air gap that helps with the reduction of thermal bridging, condensation control and addition of roofing blankets. They are sometimes offered as a solution to improve the performance of the roof by ESD consultants in their Part J or performance solution reports.
