Cam Watu insulation: characteristics, advantages, features of choice

Stone cotton wool as a heater has high demand in the building materials market. There are many stone wool manufacturers. We offer to consider the features, advantages and recommendations for the choice of this material.

Stone cotton wool: origin and manufacturing process

The origin of stone cotton wool is associated with the natural process of eruption of the volcano. When the molten lava rolls down, it is divided into fibers and wind, falling on it creates a fibrous structure. This material has high strength and operational characteristics.

The main component from which the stone cotton wool is produced by the rocks of basalt, metamorphic or mirgel origin. The most important indicator of high -quality stone wool is the property of acidity, which shows the number of acidic and main oxides in the composition of the cotton wool.

The most high -quality stone wool is made of basalt type breed, into which carbonate additives are introduced that regulate its acidity.

A high level of acidity of stone wool increases its water resistance, which means that it makes cotton wool more durable and durable. Another element that is part of the stone cotton wool is a binder. Its main function is the binding and fastening of fibers, and giving a certain form and consistency to the product. The binding elements acts:

binding based on bitumen;
binders of synthetic origin;
combined substances, which include several components;
Binding bentonite type.

The most popular connecting element of stone wool, which is most often used in the process of its production, is a synthetic material in which phenol -formaldehyde resins and hydrofibing plasticizing additives are present.

The material that has become the basis for the manufacture of stone wool is called pele hair. He looked like a thin thread that was formed from a volcanic rock. The modern stage of the production of stone wool resembles the process of eruption of the volcano. Rock rocks are sent to the furnace, the temperature in which reaches one and a half thousand degrees Celsius. They are melted and subjected to the process of separation into fibers. There are several ways to work this process:

BUSINESS method using fans;
centrifugal and rolling methods;
The method of blowing and centrifugal;
a combination of centrifugal dignit and filter method;
Other methods.

When the breed is divided into fibers, then the process of introducing binders and giving it to the form follows. This process includes spraying the binder, which is introduced into a cotton mass or watering of the mass with this substance. The stone carpet is sent to the process of heat treatment, during which the binder begins to perform its functions. The binder content is about three percent. Then the stone cotton wool is cut in accordance with the previously established dimensions, packaged and prepared for sale.

Stone cotton wool characteristics and advantages

The first and most important property of stone cotton wool, which determines its use as a heat insulator is its high heat -insulating ability. Thanks to this, it copes well with the process of regulating the temperature in the room. In the winter season, stone cotton wool does not miss the cold, and in the summer - heat. This property depends on the calculated coefficient, since various materials are characterized by different levels of thermal conductivity. Even at high temperatures, stone cotton wool does not lose its properties and still performs its functions. Therefore, stone cotton wool cannot be burned, does not ignite and protects insulated structures from fire.

The temperature of more than a thousand degrees Celsius does not affect the characteristics of stone wool. Even at such a high temperature, it does not melt, does not burn and performs its functions properly. Although the evaporation of the connecting element occurs at a temperature exceeding two hundred degrees. Due to the presence of fireproof properties, stone cotton wool helps to avoid fire and destruction of the construction of the building in its occurrence. Therefore, stone cotton wool has a fairly wide area of \u200b\u200bapplication, it is used for thermal insulation of both multi -storey and one -story buildings, schools, offices, private houses, cottages, etc.

Almost all the time of use, a binder, if it is high -quality, provides a lack of shrinkage and a constant shape of a cotton wool. This property helps Vata withstand mechanical influences. After all, it is used not only for thermal insulation of the walls, but also the floors that are under constant exposure and load. If low -quality materials are used as a binder for stone wool, it eventually loses its shape and does not perform its functions.

Due to the fact that the fibers of stone wool intersect, stone wool is an excellent sound insulator that protects the room from the effects of extraneous sounds and street noise. Interior walls, for thermal insulation of which stone wool are used, are characterized by the presence of a reduced sound level in relation to neighboring rooms.

Another function of the binder is stability before moisture and vapor permeability. These characteristics allow you to adjust the level of humidity in the room, while excess moisture is not absorbed into the insulation layer, thereby violating its structure, but is displayed out. The climate, the room becomes comfortable and favorable for living. The dry state of stone cotton wool leads to the fact that mold, fungus are not formed in it and other microorganisms are not diluted.

Stone cotton wool is environmentally friendly material, in the production of which natural materials are used that do not have a negative impact on the environment. The use of stone wool allows us to ensure significant energy savings, thereby improving the ecology and preserving electricity.

The scope of the use of stone wool insulation

Among the heater based on stone wool, the most common is stone wool from basalt breeds. It has the highest water -repellent properties, so it finds use when warming pools, baths or saunas. It allows the thermal insulation of pipeline systems and other engineering communications.

Thanks to the chaotic spread of fibers in stone cotton wool, it is able to withstand the largest loads. Therefore, it is used in the insulation of foundations and floors.

In the ratio with strength, stone wool is stiff and more elastic. The stone wool of the soft structure is used in unloaded areas of building structures, as well as when laying wells and ventilated facades, which have a low air flow and medium ventilation gap.

The use of semi -rigid stone wool is associated with the systems of the ventilated facade, which have an unlimited air flow. It is suitable for multi -storey designs. This type of cotton wool is well installed in air water structures, where it provides their heat, sound insulation and fire safety.

Stone wool of segment, cylindrical or semi -cylindrical type is used in thermal insulation of pipeline systems.

Hard basalt wool suitable option for structures that are subjected to a large load.

Coating stone wool happens:

fiberglass;
foil;
wire.

Studying about stone cotton wool reviews, we propose to consider the main sectors of its use:

1. The insulation of construction structures - stone cotton wool allows you to build thermal, sound and fireproof isolation in buildings of almost any purpose. Stone wool improves thermal insulation qualities of walls, facades, ceilings, floors, chimneys and ceilings.

2. When performing technical insulation, the use of stone wool allows you to equip ventilation, air conditioning or smoke removal systems.

3. When equipping fire -retardant systems, stone cotton wool increases the fiery resistance of building elements, such as ceilings or metal structures. The use of stone wool allows you to increase the fire safety level of the entire building.

4. In the industry of shipbuilding, stone wool provides thermal insulation of judden and their individual parts.

Recommendations for choosing stone wool

Before buying stone cotton wool, it is necessary to clearly determine its functional load and the volume of the area that needs to be insulated.

For a heater, stone wool, the price depends on such factors:

manufacturer;
The density of the material;
type of binder used in production;
type of breed from which stone cotton wool is made;
amount of material;
The presence of an additional coating layer.

Stone cotton wool for the facade should be strong and dense, since this part of the building is exposed to the environment.

Previously, the quality of mineral wool was determined based on its density, but this statement is not relevant now. Since modern stone wool manufacturers develop a material that, despite the low density, is well opposed to mechanical influences.

Therefore, when choosing stone cotton wool, pay attention to the ratio of the characteristics of the strength to the gap or to compress to the operational features of the use of insulation.

When choosing the material, carefully study the manufacturer's recommendations on its use. Most instructions indicate the scope of cotton wool. Stone cotton wool is an open -porous insulation that requires an additional layer that protects it from the influence of moisture and water.

Pay attention to the brand of the manufacturer, the most high -quality is the stone cotton wool Rockwul, Urs, Technonikol. If there is a choice between the German manufacturer and another company, it is better to give preference to the first, since the stone wool made precisely in Germany has the highest quality due to the fact that the certification organs of this country are the most picky for these products.

Keep in mind that its cost depends on the density of the material, so you should not choose too dense cotton, where the material of medium or low density will be enough.

You should not choose stone cotton wool based on its low cost, it is better to buy products more expensive. Since cheap material in a few years will lose its properties, and redoing the facade of the building or gender is much more expensive than buying a stone wool of higher cost.

Pay attention to the location of the fibers, there are three types of mineral wool determined by this criterion:

vertical,
horizontal,
The chaotic location of the fibers.

The first and second option increase the stability of mineral wool before mechanical influences, and the third - positively affects its thermal insulation and soundproofing properties.

Varieties of mineral wool in relation to its brand

In relation to the density, stone cotton wool is divided into:

1. Mark P - 75 - used for thermal insulation of unloaded horizontal surfaces, such as attic rooms, sometimes roofs. This material is appropriate when warming oil, pipeline and gas pipelines.

2. Mark P - 125 - used for thermal insulation of unloaded areas located both vertically and horizontally. With the help of such cotton wool, internal partitions are built, floors and ceilings are insulated. They are suitable for installation in a three -layer brick, aerated concrete, expanded clay concrete system.

3. Stone cotton wool - 175 - suitable for thermal insulation of walls, the basis of which is a metal profiled sheet or reinforced concrete in which there is no concrete screed.

4. PPG - 200 - high stiffness slabs that increase the fiery resistance of engineering and construction facilities.

In terms of stone wool, they depend on the manufacturer. The option of ordering individual sizes of roll or stone wool slabs is possible.
