Mixed partition made up of two independent Pladur® linings, both braced on each side by a Pladur® partition wall. Each partition is made up of a structure of galvanised sheet steel profiles, built on studs (vertical elements) and channels (horizontal elements), on whose interior side, depending on the free-standing height, the studs will need be braced with brackets attached to the core of the studs and the Pladur®, partition, leaving a space between the structure and the partition base of a minimum of 10 mm. On the exterior 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 floors and ceilings, etc. Completely finished with Quality Level 1 (Q1) 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 project). Core of each Pladur® structure filled completely with mineral wool. Installed according to Pladur® recommendations, UNE 102043 Standard and CTE requirements.
