Gypsum boards are increasingly being used in construction. This is explained by its low price and wide scope.
Main characteristics and purpose of drywall sheets
Drywall is used for the manufacture of interior partitions, leveling walls, figured or multi-level ceilings, various types of niches and shelves. For the installation of GKL, metal profiles are required to which it is attached. All the necessary work can be done independently, but you need to clearly define the characteristics of the future design. Suspended ceilings look beautiful and aesthetically pleasing and do not require serious financial costs. Drywall partitions are easy to install. There are several types of GKL, which differ in thickness and scope. The material putty is excellent, and wallpaper fits well on it, and it can also be purchased at any hardware store or on the market. If necessary, ceramic tiles or decorative stone laths are placed on moisture-resistant drywall.
Varieties of drywall
Gypsum boards differ instructure, density, thickness and material. The scope of their application depends on this.
There are several types of this material:
- Wall. The most common type of drywall is mainly used for interior wall cladding. Well suited for the installation of interior partitions. The thickness of the drywall partition will depend on the direct purpose of the partition, i.e. whether it will be interior or simply decorative.
- Ceiling. The main difference between this drywall and wall drywall is the thickness. Since the ceiling sheets are designed to be mounted on a suspended profile frame, they should not have a lot of weight, so their thickness is a few millimeters less.
- Arched drywall. Designed for the manufacture of uneven shapes, such as circles, semicircles, slopes of arches. It is distinguished from other types by the smallest thickness of drywall, which allows it to bend well. Experts recommend installing two layers of this material, since arched drywall sheets are very fragile due to their small thickness.
- Moisture resistant. This drywall has a large thickness, so it can be used for facing with stone or ceramic tiles. From the name it can be seen that the scope of its application is mainly rooms with high humidity (bathrooms, pools, baths). GKL does not swell from moisture due to the presence of a special film layer that does not let moisture in. Of course, everything is within reason. If you put it completely in water, then the protective layer will no longer save.
GKL dimensions
Depending on the type, the thickness of the drywall sheet varies from 0.65 to 1.25 cm. Also, the size of the drywall sheet depends on the application.
- Wall. Width 120 cm, length can be 250-300 cm. Thickness 1.25 cm.
- Ceiling has standard dimensions, but the thickness of drywall is less and is 0.95 cm (to reduce weight).
- Arched - the thinnest drywall sheets, this gives them flexibility. The thickness is no more than 0.65 cm. Because of this, large loads on the sheet are contraindicated.
- Moisture-resistant drywall, in view of its scope, has a thickness of 1.25 cm.
Additional materials for GKL installation
Of course, plasterboard sheets are not simply screwed to the ceiling or wall, special profiles are required for their installation. The thickness of the drywall profile is also different and depends on the structure being built.
The guide profile has standard dimensions: height 40 mm, width 50 mm, 75 mm or 100 mm. The dimensions will depend on the thickness of the drywall partition you have. It is important to know that according to SNIP, the minimum thickness of an interior partition should be at least 100 mm. It also depends on mechanical influences what thickness of drywall will be used. For structures with a large layer of insulationor soundproofing materials, a wide guide profile must be used. The thickness of the plasterboard partition varies from 100 to 300 mm.
What happens if you choose the wrong GKL thickness
When choosing drywall sheets, special attention must be paid to the thickness, since a special type of material must be used for each type of work. For example, if a moisture-resistant drywall of great thickness (and, accordingly, weight) is mounted to the ceiling, the structure may simply collapse, not to mention the extra waste of money. Also, if you use thin arched plasterboards on an interior partition, you get a fragile structure that is unstable to mechanical stress. Using ordinary drywall in high humidity conditions will cause it to swell and subsequently deteriorate. From the above, we can conclude that each type of material should be used strictly for its purpose.
Conclusions
As you can see from the article, before you get to work, you need to be well defined with the scope of the GCR. The thickness of drywall plays a huge role in installation. And in case of the wrong choice of material, negative consequences are possible. It should also be borne in mind that drywall is quite fragile compared to masonry, therefore, if possible, mechanical impact should be excluded. Definitely - the use of drywall during construction will significantly save the budget. And the result will please you with beauty and aesthetic appearance. good luck to yourepair!
