Partition made up of a structure of galvanised sheet steel metal profiles 90 mm wide and 0.7 mm thick, with Pladur® CH-90 studs and Pladur® E-90 studs (vertical elements), spaced 600 mm on centre, and Pladur® J-92 channels (horizontal elements). Toward the inaccessible side (hollow area) a partition face is created enclosing a Pladur® CH plasterboard 25 mm thick with E-90 first and last studs and CH-90 studs in between, having a continuous band of Pladur® intumescent acoustic sealant between both materials. On the accessible side of this partition, one or more 15mm thick Pladur® F plasterboards are screwed on, including joint treatment. Afterwards a self-bearing lining is applied, consisting of a structure of profiles of galvanized steel sheet metal on Pladur® studs and channels (horizontal elements), on whose interior side, depending on the height to be covered, the studs must be braced with angular pieces that are attached to the core of the studs and the Pladur® CH partition, leaving a space between the structure and the partition of a minimum of 10 mm. On the exterior side of this structure one or more Pladur® plasterboards are screwed on. Commensurate amounts of Pladur® materials: screws, compounds, joint tape, resilient/acoustic perimeter joints, etc., as well as anchors for channels on the floor and ceiling, etc. Completely finished with Quality Level 1 (Q1) for tile finishes, laminates, furring, etc., with Level 2 (Q2), Level 3 (Q3), Level 4 (Q4), except on the inaccessible side of the system. Core of each Pladur® structure filled completely with mineral wool. Installed according to Pladur® recommendations, UNE 102043 Standard and CTE requirements.
