Gypsum board frames usually consist of “C” uprights (studs) and “U” guides (tracks). A “U” guide is usually placed along the entire profile of the wall or ceiling, then “C” uprights are inserted into the wings of the frame, onto which the joints of the drywall panels are later made. The entire structure is made of cold-formed sheet metal profiles and is connected to the adjacent load-bearing elements by dry building. Its special feature is to increase thermal and/or acoustic insulation by using the cavity to improve thermal-acoustic performance. This profile proposed by PM is an elastic galvanised steel “U” track, ideal for making load-bearing structure for single or double layer drywalls with single or multiple claddings (double, triple, etc.). The special knurling guarantees greater plaster adhesion. The material, treatments, dimensions, thicknesses and special processing are defined with the customer to allow for the greatest possible customisation.
