It consists of a plaster core, reinforced with reinforcing cardboard. The edges are thinned on both sides to allow jointing. The thickness is variable (9.5 cm and 12.5 cm for the most common). The usual height is 250 cm, for a width of 60, 90 or 120 cm. The weight of a BA 13 (12.5 cm thick plate) is 10.2 kg per m2. There are waterproof plasterboards on the two facings, for humid rooms, vapor barrier plates, resistant to the diffusion of water vapor and high impact resistance plates, for exposed places.
Handling and storage
Relatively fragile, plasterboard must be subject to special precautions. It takes two, or even three, to handle them, given their dimensions and weight. Carry them on edge, to avoid deformation. There are also plate holders and carrying handles that simplify handling. However, store them flat, one on top of the other, in a dry and healthy place.
Lightness, large dimensions, good impact and fire resistance are the great qualities of plasterboard. In addition, this material makes it possible to produce thin partitions having smooth facings which do not require any preparation for the use of decorative coatings such as wallpaper or tiles.
All types of partitions
Plasterboard allows the creation of distribution partitions, i.e. internal partitions in an apartment, as well as dividing partitions between two apartments - alternating or double reinforcements are then used. Today they are used more for the construction of light partitions than any other material.
