A movable tile with head lock, equally elegantly proportioned and functional.No application is excluded, including redevelopments and renovations. The considerable sliding clearance allows for the very easy adjustment of the tiles to the roof battening – these are ideal pre-conditions especially for mansard roofs with short rafters. But TERRA OPTIMA also captivates with additional extraordinary characteristics. The double interlocking with lateral water path guarantees an optimal moisture protection. Gentle cavities result in an agreeably clam roof structure.
