Minvata is a natural fibrous product derived from rocks and blast furnace slags. In the construction industry it is known as the most popular heat-insulating and stable material. Material made from raw materials is very high quality and is used for a long time. What can not be said about the minivate made of metallurgical slag. Such cotton wool is not absolutely reliable and durable. It quickly loses its qualities at temperature changes, high humidity and various loads.

There are several types of mineral wool :
- glass wool;
- stone( basalt) cotton wool;
- slag wool.
Properties
This material is successfully used in the construction of temporary and permanent buildings, as well as in the construction of summer cottages. In addition, it is necessary to distinguish the following important properties of mineral wool:
- excellent fire resistance( does not allow ignition of all contacting materials, and does not burn itself);
- non-hygroscopicity( perfectly prevents intensive penetration and absorption of moisture);
- vapor permeability( this is an important property, as in some rooms it is necessary to regulate the moisture level and create a suitable microclimate);
- high sound insulation( does not let sound waves through, therefore it is actively used in the construction of night clubs, discos and other noisy institutions);
- chemical and biological resistance( perfectly protects from harmful and corrosive substances);
- ecological compatibility( it consists exclusively of natural rocks that do not carry any harm in themselves, it has been checked by specialists);
- corrosion resistance( does not create corrosion of metals that are in close contact with it).
Technical characteristics of mineral wool
The density of mineral wool can be different - from 20 to 350 kg / m3.The required density should be chosen based on its direct purpose. For example, if you plan to insulate the walls, then you need to choose a material with a higher density, if the ceiling is insulated, then you can do less dense option.
Technical characteristics of mineral wool can also vary depending on the type of material.
Each type has its own technical characteristics, so you can specify the average values for the material as a whole:
- the maximum heating temperature is up to 700 degrees Celsius;
- coefficient of thermal conductivity varies from 0.03 to 0.1 W / m * K;
- hygroscopicity is high.

Advantages of
Also, it is worth highlighting the advantages of mineral wool: it is very light, fast and convenient to install, perfectly protects from a variety of negative factors, it is inexpensive and is used for years. This is an excellent solution for modern building crafts.
Disadvantages of
But, there are also disadvantages: it has an increased fragility, it often clings and compacts, it can rub into dust, and the mouse feels good in it.
In general, the reviews on the minvat are quite positive. Many builders use it to insulate their facilities, even though it has small flaws. This material is popular because of its advantages. It will be used in construction, until a more convenient and convenient alternative appears.
