Drywall construction means structure installation made from gypsum boards (plasterboards). The load-bearing structure is made of galvanised profiles for which various suspension and connecting elements are installed depending on their type and shape. Various screw types are used during installation. After fastening the boards, all expansion joints between the individual pieces have to be reinforced in order to ensure their surface invisibility and protection against cracks. During the final surface treatment (skimming), aluminium or plastic beads are used as details on the board edges. The advantage of aluminium beads is their low thickness, the advantage of PVC beads is in the higher durability, additional impact protection and wide variety of visual detail.
