Rockwool stone wool: which lead to overheating of the gasoline or diesel engine, price and properties of the material
When the insulation of the premises, then be sure to use multifunctional material. Moisture resistance depends on its quality, noise insulation, fire safety and heat retention.
Stone wool has all these properties, differs in high manufacturability. And the sizes of such material allow to use it in various areas of the construction industry. Professionals find it very profitable to use Rockwool, as a multidisciplinary insulator.
Types of stone wool
This material is widespread in Russia, today it occupies a leading position among similar materials. There is a wide range of types of stone wool.
Rockwool attaches well to a variety of materials, which increase its quality. The price of such materials can reach 3000 rubles. These include:
- Skolholst;
- Foil.
In those places, where good sound insulation is required, it is better to use fiberglass. Rock wool is good for insulating working units.
Foiled Rockwool, able to withstand very high temperatures. This stone insulation is installed near a variety of devices, where there is a constant high temperature and there is a risk of fire.
Application
Rock wool has a natural origin. Basically Rockwool, this is a real natural stone. Therefore her, of different sizes, began to be used in various buildings.
The low price and excellent properties allowed to use this material as an excellent thermal insulator of the most various constructions.. These can be multi-storey buildings or small separate rooms. in addition, Rockwool can be used in institutions, to which they are presented high environmental requirements. These include:
- Sanatoriums;
- Hospitals;
- Polyclinics;
- Schools;
- Kindergartens.
Production
The process of obtaining stone insulation in some cases resembles a volcanic eruption.
After getting to the factory, stone is melted in furnaces, where tthe temperature reaches 1500 degrees. The result is a substance, very similar to a bench.
Then a special centrifuge is turned on, in which the resulting mass is treated with strong air currents. The result is stone fibers. They add special binders. They give the fibers the desired shape.
Special water-repellent components are also added to the composition of the obtained fibers. Then plates are formed from fibers, which are sent to the warehouse for complete cooling and curing.
Negative and positive qualities of Rockwool
The main purpose of stone wool is thermal insulation of various structures. Having different sizes and low price, it has become the most popular in the construction industry.
The material has high strength, it refers to non-combustible materials. Rock wool can withstand temperatures above 1500 °C .
Rockwool is used for insulation:
-
The walls:
- Floors;
- Roofs;
- Partitions;
- Facades;
- Pipes;
- Factory and non-residential premises.
Rockwool has a lot of positive qualities. This material meets all modern environmental requirements, does not harm health, creates conditions for saving a lot of energy.
Rock wool is an excellent sound insulator, has good moisture-insulating properties.
To the characteristic advantages of Rockwool can be attributed:
- Durability;
- Strength;
- Vapor permeability;
- Resistance to mechanical deformations.
Specifications
As already mentioned, such cotton wool can be made of different sizes. Its maximum height reaches 1200 millimeters. Moreover, the thickness of the plates may be in the range 40-2000 millimeters. The maximum width of the stone slab does not exceed 600 millimeters.
The value of cotton density also fluctuates. It all depends on the conditions, where it will be installed. The minimum value of density 30 kg / m3, and the maximum can be reached 210 kg / m3.
The disadvantage of Rockwool material is a favorable environment for the existence of small rodents. Harmful phenolic compounds may be present in Rockwool basalt wool. But this usually does not happen, as the process of making stone wool is carried out strictly in compliance with all technological requirements. This material is completely safe for humans, it does not harm the environment.
What is the cost of Rockwool?
Each brand of such stone wool differs in its characteristics, which have an impact on price formation.
Vent Butts insulated ventilated facades. The price of packaging reaches 600 rubles.
Light stone wool, having high hydrophobic properties, sold at a price 480 rubles.
Acoustic Butts, brand of stone wool, creates sound insulation, sold at a price 600 rubles.
Facade series, resistant to mechanical deformation, estimated at 680 rubles.
Ruf stone wool, which insulates the roof, can be purchased at a price 700 rubles.
«Rockwall Cavity Batts», that goes on warming of multilayered walls, costs about 550 rubles.
Fire safety
In case of fire, stone wool does not allow the fire to spread quickly around the room.
Fibers can withstand enormous temperatures, over 1000 degrees. They protect the structure from fire, prevent the destruction of the building. Rock wool does not emit smoke when ignited, there is no strong heat, there are no hot drops.
Environmental friendliness
Rockwool, this is the first thermal insulation, is considered absolutely safe and meets the requirements of ecology. She was awarded the EcoMaterial Green. That is, it can be used to insulate any building, as well as children's rooms.
Quality control
When buying stone wool, you need to take into account its features. It should not spill crumbs. This is very easy to check, is it enough to just slap on the stove. No particle should fall to the floor. This test is especially true for facade insulation. After all, such work requires a dense insulation.
Rock wool should be in the composition the minimum number of resins. It must be resistant to high temperatures. In the accompanying documents, the maximum temperature and warranty period are indicated.
Let's summarize all the above. There are no general guidelines for the use of rock wool. This insulation refers to highly specialized materials. Therefore, everyone sees in it an individual solution to the problem.
