Qualitative characteristics, advantages and scopes of gypsum cardboard
About 20 years ago nothing was known of this finishing material though plaster was long since applied to a decor and arrangement of dwellings. And today designers of rooms do not represent the work without gypsum cardboard. It inspires on creation of difficult multilevel ceilings with effective illumination, on registration of niches, shelves, racks, curvilinear partitions etc. Sheets of gypsum cardboard possess sound - absorbing and energy saving properties, have small weight and are quite comfortable in work.
Popularity of material is explained also by the fact that it is absolutely harmless, and it is powerful argument in favor of its application for those who seek to make the dwelling not only beautiful, but also safe.
In its basis, as appears from the name, plaster - the strong natural mineral consisting of calcium sulfate, revetted on both sides with a cardboard. It is proved that plaster is a mineral with a low radioactive background - it is one of its main advantages. Operational qualities of natural plaster increase thanks to addition of the special additives doing material at the same time both flexible, and firm.
The cardboard carries out also a role of a strong framework, and forms an excellent basis for the subsequent putting any finishing material - plasters, paints, wall - paper and even a ceramic tile. Excellent physical and hygienic properties allow to use gypsum cardboard in all premises, including nurseries. Pleasant addition to all listed qualities - the low cost of such covering. And it means that gypsum cardboard can be used even in the most low budget repair projects.
And though some sceptics nevertheless abuse it for application of additives and education in dryness or humidity, gypsum cardboard remains the most demanded and safest material. Perhaps, these doubts are connected with property of gypsum cardboard to absorb the excessive moisture which is contained in air and to give it back in case air is too dry. Experts assure that it is safely possible to call all these claims far - fetched.
It is remarkable that all properties of gypsum cardboard can be increased many times if material intends for any specific goals.
Producers offer several types of gypsum plasterboards:
- Gypsum cardboard usual (marking of HL). Is ideally suited for rooms with the usual mode of functioning and humidity - rooms, offices, etc. Externally such gypsum cardboard differs from other types in the fact that its sheets have a gray shade.
- Gypsum cardboard moisture resistant (marking of GKLV) - modern revolutionary material which appeared in our market not so long ago. The covering is intended for finishing of rooms with the high level of humidity. Thanks to it began to carry out many works in damp rooms much quicker and easier. Unlike usual, moisture resistant gypsum cardboard contains the special hydrophobic, antimould and anti - fungal additives protecting it from influence of the damp environment. All edges of sheets of a zavaltsovanna cardboard edges. Despite the lowered moisture saturation, this material "breathes", so, prevents emergence of condensate. However, in that case if constant humidity of air higher than 80% indoors remains, not to do without the thought - over system of ventilation - even moisture resistant gypsum cardboard will begin to inflate and lose the original form over time. Before buying moisture resistant gypsum cardboard, pay attention to conditions of its storage. Material has to be indoors, and on its surface existence of stains is inadmissible. Useful will be to break off a leaf piece - in warehouses there are always sub - standard remains. In case material strongly crumbles, in this shop or a warehouse it is better to refuse purchase. According to the international requirements, sheets of moisture resistant gypsum cardboard are painted in greenish tone.
- Gypsum cardboard fire - resistant (marking of GKLO). This covering is developed especially for application in rooms with high requirements to fire resistance, so, differs in special characteristics. Usual gypsum cardboard, in cases of contact with high temperatures begins to evaporate moisture, becomes fragile, bursts, showered, and all design loses the initial durability. The fire - resistant covering reinforced by special vitreous fiber and added with special active agents begins to collapse only after 45 minutes of continuous influence of a flame. It is connected and with the fact that the structure of the plaster core enters about 20% of the gross weight of a sheet of kristallizirovanny water which, coming into contact with fire, begins "to extinguish" a covering from within. Fire - resistant gypsum cardboard differs in higher price and requires bigger attention at installation. You should not buy too cheap sheets, in this case you save on the safety.
