Гипсокартон является самым популярным на Today building material. It is durable and flexible. It is completely harmless to the human body and has a lot of other wonderful properties.
Characteristics of drywall
Drywall - a type of finishing material, which is made in the form of a sheet. In the middle of the product there is a plaster base, and on the sides there are several layers of cardboard that perform 2 functions:
- Protective. On the front side, the paper is stronger and more resistant to abrasion.
- Cardboard elements are able to stretch and hold the internal pressure of gypsum, which may appear when working with it or during operation of the finished structure.
But the compression cardboard does not work.
Basic views
Plasterboard constructions are often used to implement different types of work: finishing and creating all sorts of decorative elements.
Drywall is:
- ordinary;
- moisture resistant.
Further, variations in size andmoisture resistant plasterboard functions. In their composition, these systems have not only sheets of dry plaster, but also elements necessary in order to quickly mount the structures of the bearing base and configurations of high complexity. They can also be used to complete all the work on the dry finishing process in a short period of time; this will not require activities that are associated with the formation of high humidity (plastering and other actions). A truly high-quality drywall has really changed the approach in the construction and finishing works.
Advantages
Основными плюсом гипсокартона считается простота and ease of finishing, rather small weight and good environmental friendliness. Gypsum plasterboard professionals can create all sorts of, even the most unusual decisions of design and construction ideas. Moisture-resistant drywall is considered to be a very high-quality building material. Usually it is of standard size, so you can even before the construction of structures begins to easily miscalculate the required number of sheets and navigate the estimated costs.
Dimensions
The size of moisture resistant gypsum board can be:
- layer level: 9.5 - 12.5 mm, also from 8 to 24 mm;
- product width: from 1.2 to 1.3 m;
- height: ranges from 2.5 to 4.8 meters.
Dimensions of products may be different, depending on the preferences of the customer.
Appearance of moisture resistant drywall
The most popular manufacturer of drywallKnauf products are considered. Today it is one of the most famous companies. On each sheet there are printed letters by which you can determine the purpose of this material.
The basis of a large variety of drywallSystems are simple frame elements that can be mounted very quickly. Gypsum cardboard moisture resistant Knauf has amazing properties. For example, it can be given absolutely any shape, bend it in a moist form to create all sorts of decorative elements. Moisture-resistant drywall (VGKL) is impregnated with waterproof and antifungal impregnation, and the core is made with the use of additives that significantly minimize the absorption of moisture. Such plasterboard sheets are used for wet areas: bathrooms, kitchen, garage.
Moisture-resistant drywall "Knauf" is considered oneOf commonly used building materials among analogues. This building material is produced in the form of a rectangular sheet (two-layer cardboard, including gypsum with reinforced substances). The size of the moisture-resistant drywall sheet: 1.2 mx 3 m, a layer of 12.5 mm.
Moisture-resistant GKL "Knauf" has a high resistancemoisture absorption, and therefore is often used in rooms with high levels of humidity and poor air circulation, while completely environmentally friendly and harmless to health.
Hygroscopicity
Гипсокартонные листы гигроскопичны.This is considered both a plus and a minus. The ability to absorb moisture material limits the use of ordinary drywall sheets. For their installation, an auxiliary waterproofing is needed, so it is preferable to purchase moisture-resistant plasterboard for this purpose. In the bathroom, ordinary sheets will soon become unusable.
How to distinguish between a variety of drywall?
All drywall, which is produced in the lasttime, usually of typical sizes and has the abbreviation GCR, GKLO and GKLV (GKL - gypsum plasterboard, GKLO - gypsum plasterboard refractory, GKLV - gypsum plasterboard moisture resistant). One surface of ordinary plasterboard products has a brown tint, while the other has a natural paper color.
To determine which drywallmoisture resistant, just need to look at the color of the surface of the sheet. The moisture-resistant material is painted green and has special qualities due to the impregnation of antiseptic, antibacterial and hydro-resistant solutions. It is they who guarantee him maximum immunity to moisture. All additional substances that are part of the moisture-resistant material, a little reflected in the severity of the product. The weight of one sheet of moisture-resistant drywall of a typical size is only a couple of kilograms heavier than a sheet of drywall.
Technical characteristics of moisture resistantmaterials make it possible to use it in the decoration of the kitchen, bathrooms, but we must not forget about the protection of the outer side of products. To protect drywall use special primer or water-repellent paint. Can protect polyvinyl chloride or ceramic tiles located on top of drywall, all kinds of waterproof film.
What should I look for when buying GCR and profiles
Существуют так называемые упаковочные листы.In the production of gypsum sheets, the material is laid on large pallets, moved in packs by electric trucks or other loading equipment. The bottom sheet, which is a mechanical impact, as a result, is deformed. It is called the packaging. On these sheets leave a special label "Packing List". It should not be sold. He is thrown away like a marriage. When buying this is worth paying attention to.
При покупке следует осмотреть листы на integrity. Drywall should not be with broken corners, paper should not be torn off. Sheets must be stored in a recumbent position in closed warehouses.
Also pay attention to the level of the layer profiles and the hardness of products.
Profiles for drywall: UD and CD.
CD quality profile is not deformed underthe influence of physical force, and if you take the UD profile by the end and lift it with one hand, the profile should not create a feeling that it can break under its own weight. The reliability of the whole structure depends on the size of the profile layer. Naturally, the thicker the layer, the stronger the plasterboard structure will be.
Usually primed ends of profiles speak of bad galvanizing or improper storage. Galvanization should be seen uniformly shine, it should not be white marks.
CD and UD drywall profiles are 3 and 4 m long,but at the production plant (by pre-order) they can produce any length. This may be advisable if, for example, you want to finish the wall with a height of more than 4 meters, then you will not need to connect the CD along the length.
Application area
In the process of lining may be a question ofwhat specific surface should install moisture resistant drywall. Any product has special edges with different profiles. Such a useful solution is necessary in order to close up the gap between the products with the help of various building materials.
There are several types of edges:rectangular (no sealing required), come with steps (a thin profile made of reinforcing tape and plaster for putty) is required, as well as a rounded shape (putty without tape is required).
When laying drywall sheets outsideshould be located chamfering part. When using ordinary sheets of drywall externally should remain that surface, which is painted a lighter shade. The same instructions should be followed when installing a moisture resistant material.
Moisture-resistant drywall sheets canuse instead of conventional counterparts, but ordinary sheets instead of water-resistant should not be used. True, the cost of moisture-proof material is a bit more expensive and it is better to apply it exclusively for certain premises. Mount it instead of the usual meaningless. When using moisture resistant drywall, the manufacturer advises to control the required level of air circulation. It is necessary that drywall had the opportunity to return the accumulated moisture.
Conclusion
From all described it follows that the sizemoisture resistant drywall does not differ from the ordinary. At the same time, it is more multifunctional, which makes it possible with the help of it to carry out facing works indoors: this material is used to finish walls and ceilings, to build various partitions and other systems.
