Patent ID: 8745928

Claim:
A lining for surfaces, comprising at least two profiled frame elements extending in a longitudinal direction along the surface to be covered in spaced relationship to each other, at least one membrane element having a face side and a reverse side remote from the face side and disposed between said profiled frame elements and connected to said profiled frame elements, at least partially, by means of attachment means that engage said membrane element from behind, wherein said membrane element, when in a loose state, is capable of moving freely in said longitudinal direction, and means adapted to taughten said membrane element in a transverse direction between said profiled frame elements, comprising at least two vertically adjacent zip fasteners extending in the longitudinal direction and arranged such that closing of a first zip fastener of said at least two vertically adjacent zip fasteners produces a first, loose state of said membrane element between said profiled frame elements and subsequent closing of a second zip fastener of said at least two vertically adjacent zip fasteners causes a second, taughtened state of said membrane element between said profiled frame elements, wherein, for protection of said membrane element, at least one dimensionally stable protective cover is provided on said reverse side for draining off condensation water that is formed on a top surface of the lining, the protective cover having at least one of an arched or curved cross-section, wherein the protective cover covers an area that is larger than that of the membrane element and protrudes laterally beyond the membrane element, and wherein the protective cover includes at least one of a corrugated or ripped sheet or plate for draining water to the sides of the protective cover through wave troughs in the sheet or plate.
