Mixed partition made up of two independent Pladur® linings, both braced on each side by a supporting wall (to be determined by the design). The final thickness of the mixed partition is determined by the base wall. Each lining is made up of a structure of profiles of galvanised sheet steel, built on studs (vertical elements and channels (horizontal elements), on whose interior side, according to the free-standing height, the studs will need be braced with brackets attached to the core of the studs and the base wall, leaving a space between the structure and the wall of a minimum of 10 mm. On the exterior side of each lining structure, one or two 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 on the floor and ceiling, etc. Completely finished with Quality Level 1 for tile finishes, laminates, furring, etc. Also with Level 2 (Q2), Level 3 (Q3), Level 4 (Q4), according to the surface finish (to be determined by the design). Core of each Pladur® structure filled completely with mineral wool. Installed according to Pladur® recommendations, UNE 102043 Standard and CTE requirements.
