How is drywall made? Drywall consists of various components. The main components are plasterboard panels and a substructure. This can be made of wooden posts or aluminium profiles. The connection seals, nail plugs and other fastening materials are also used. As the name suggests, the materials are delivered to the construction site in a dry state, meaning that the wall can be constructed immediately. Gypsum plasterboard is made from stucco plaster, additives and multi-layered cardboard - these are the most important raw materials. A distinction is made between building boards and fire protection boards, which are abbreviated to GKB and GKF. Fire protection boards are used, for example, for shafts that connect several fire compartments. A distinction is also made between impregnated and non-impregnated boards. Impregnated boards are used in damp rooms and are abbreviated to GKBI and GKFI. There are different types of metal stud profiles. Horizontal UW profiles are attached to the ceiling and floor (U-shaped straight end). In between, the CW profiles are aligned vertically with a certain centre-to-centre distance (C-shape with chamfer), depending on the dimensions and requirements of the wall. Openings are created using UA profiles, e.g. for doors. A wall is erected as follows: 1. the course of the wall is marked on the floor, taking door openings into account. 2. the course of the wall is then transferred to the ceiling. 3. the UW profiles are fixed to the floor and ceiling with connection seals and nail plugs. 4. the CW studs are normally aligned to a centre distance of 62.5 cm, these must be placed with the open side in the direction of installation. The spacing of the CW profiles may vary depending on the utilisation category. 5 After the metal studs have been attached, the first side of the wall is planked with plasterboard, ensuring that the joints are offset. Auxiliary points on the board can be very helpful here. 6 Depending on the wall type, the cavity between the profiles is filled with insulation. The wall can also remain hollow if no thermal or acoustic requirements are placed on it, e.g. for facing shells for sanitary installations. 7 The second side of the wall can then be closed with plasterboard and the wall is ready for priming and painting. For timber substructures, it is important to use straight and warp-free timber. Dry construction systems are not only used for walls, but also for ceilings. Suspended ceilings or ceiling panelling are often made with drywall. There are also ready-made systems for loft conversions. ÖNORM B 3415 provides detailed information on drywall construction work. This ÖNORM is very important for us planners as well as for the contractor and must be applied during production.
