Element Resistant to Air Transfers and Thermal and Hydric Transfers in the Field of Construction, Especially for Lightweight Walls or Lightweight Facades

Abstract

An element is directed to the dry construction of lightweight walls, especially the construction of load-bearing lightweight façades or non-load-bearing lightweight façades, which do not contribute to the stability of the building. The element includes a panel based on a hydraulic binding agent and all or part of the face is coated with a polymer film obtained by polymerization under the action of radiation. The element also includes a structure, and a jointing component resistant to air transfers and thermal and hydric transfers. The element does not comprise any membranes that are resistant to air transfers and thermal and hydric transfers.
