Buildings boards or 'sheathing boards' are used within the façade build up, behind the external cladding panels. Their purpose is varied – from strengthening the lightweight steel frame racking structure to adding acoustic, fire and weather / moisture protection. They also offer a flat surface to adhere insulation to.
Drywall, also known as plasterboard is made of gypsum mixed with water and spread between two large sheets of paper. Drywall is used for the construction of interior walls and ceilings. Plasterboard is installed by lifting the pieces and attaching them to wall studs.
In residential housing construction and lightweight framed commercial construction, plasterboard is attached to studs to create walls but can also be attached to masonry walls including brick. It is also used as a ceiling lining and to create architectural design features such as arches, eaves and curved walls.
The Process of Skimming Over Plasterboard
One of the advantages of using dry lining or plasterboard is that you can apply paint directly on to the surface without having to plaster, or wait for the skim coat to dry. The joints between the boards need to be taped and jointed however, to achieve a flat surface.
Also known as plasterboard or drywall, the gypsum board is a technical name given to a plaster-based wall finish that helps in creating light walls. Even though it is an umbrella term, all of its types use gypsum, a non-combustible core, and paper surface covers them.
The cost of re-rendering/plaster versus a plasterboard dot and dab covering/plaster is cheaper for the plaster boarding. Also much quicker and drying out of new materials much faster.
While all plastering provides a form of insulation, wet plastering is somewhat more dense and more airtight than plasterboard and will therefore retain warmth better. Pros: Easy to use on any shaped project, smooth finish. Cons: Expensive, not for the DIY-er
You can paint straight onto/over plasterboard in most cases, you simply need to cover the joints and any holes created by your fixings first. Being able to paint directly onto the surface of the new wall is convenient and saves time and money. You can also plaster over painted plasterboard at a later stage
