All about stone cotton

During the construction of a new home or reconstruction of an apartment in a residential high-rise building, a matter of insulation arises. Special material designed to maintain heat allows to significantly save on heating accounts, especially in homes and cottages. Quality insulation contributes to the provision of comfortable living conditions. However, it is not so easy to choose it. And all many give preference to stoneware.

What it is?

Stone Vata – Eco-friendly thermal insulator used for the arrangement of residential and industrial premises. The secret of the preservation of heat is hidden in air immobility located in the fibers. And what is the most interesting, these fibers are made of stone.

The insulation presented is based on basalt. And the manufacture of basalt insulation has a lot in common with the natural production method. Scientists, studying volcanoes in Hawaii, found that, when exposed to high temperatures, threads folded into a validiform form. Accordingly, it is simply impossible not to use such a phenomenon.

At the factories, aggregates that support temperatures up to 1500 degrees were installed. And with such an impact, rock rocks melted like a piece of ice. The wizard, the molten mass is pulled into fibers and connect with binding elements that give the cotton required consistency and shape. In most cases, synthetic substances play the role of binders.

Prepared fibers are sent to the polymerization chamber, where at a temperature of 200 degrees, material solidification occurs. Ready wool is wounded into rolls, rolls into the slab or mats. And at the end the product is packaged by film.

Stone heat insulator can be called universal material, which is recommended to lay out under siding, plaster and other types of sheathing.

Basic properties

Despite the existing types of insulation, stone wool has undeniable pluses and a few minuses. But before you should start with positive characteristics.

  • Stone wool refers to natural products, as natural resources are used in its manufacture.
  • This material can be used in different temperature modes.
  • Stone insulation has high quality thermal conductivity.

There are several parameters to disadvantages.

  • Mouse has mouse in stone cotton. Rodents though do not use the insulation in food, still spoil it.
  • High price.

Realizing that Stone Vata is one of the best insulation options, it is worth introducing it to its technical characteristics and properties.

Thanks to the possibilities of the modern world, it was possible to develop the technology of creating a waterproof product, covering its special substance.

Parp permeability

Modern owners of houses and cottages are experiencing about environmental friendliness, housing security, microclimate comfort and fear of the appearance of mold. In this case, there are two opinions. The first judgment assumes that the house must be like thermos. The second states that the buildings should “breathe” due to the vapor permeability of the walls. Stone wool refers to second judgment, as it has a property of vapor permeability. Water molecules penetrate through the heat insulator, not condensed on the fibers, due to which the cotton will not mock. Such a heater is recommended to use in wooden buildings so that the walls can “breathe.”

Ingestion of outdoor air indoors occurs not only through the velocity, but also through invisible slots and microcracks. If the walls are deaf, and the house is completely isolated from drafts, then after a while on the walls and the ceiling, mold sticks out. That is why adherents of ecology wish to have “breathable” walls. And without a stone insulation, withdrawing water evaporation molecule, can not do.

Foreign safety

As mentioned earlier, the stone wool is made on the basis of the non-combustible gabbro-basalt group. Melting stone in production scale requires a temperature of 1500 degrees. Such a heat is comparable to the stump of volcano. The household fire will never be able to achieve a similar temperature, respectively, the insulation when exposed to even an open flame will not deteriorate and does not light up. Its fire resistance corresponds to 100% quality.

In addition to the fruitlessness of fire, stone wool is opposed to heat, reducing its strength, thanks to which the design of the house does not suffer. Speaking with simple words, the construction is not collapsed, its individual elements are not melted.

In addition, the stone wool withstands the combustion temperature, it does not emit poisoning substances, negatively affecting human health.

Sound absorption

Stone insulation is distinguished by enhanced sound insulation, and all thanks to the complex cottage structure with chaotic intertwing fibers with air layer. This property had to do with the owners of the audio recording studios attached to the residential house. Working on the full power speech system does not interfere with the rest of the neighbors. The material reliably protects the owners from shock noise.

Durability

Like any other insulation, the installed stone wool passes the shrinkage procedure. But this process is so insignificant, which means it does not affect the service life of the material. Plates or rolled rolls do not lose production form, the draft tracks do not appear between them. Today, in the process of production of stone wool, the material is treated with a hydrophobizer creating a water-repellent effect. This feature allows you to maintain the structure of the insulation in dampness and in the rain.

Ecology

Stone wool refers to the list of environmentally friendly materials. Some manufacturers are even ready to provide the appropriate Eco Material Green certificate. And yet, in the question of the environmental friendliness of the stone insulation, it should be understood.

In the near past, studies have been conducted, which revealed that basalt wool is unsafe product. In 1995, in the booklets of several companies it was stated that the fibers of the basalt insulation are connected using synthetic resins obtained by the interaction of phenol and ant aldehyde. Resin in its characteristics has a lot of differences from natural fibers. And first of all – this is the difference in temperature. Fibers, being in the oven, do not melt until the temperature inside will exceed 1000 degrees. Resin, in turn, at 200 degrees begins to decompose, highlighting the caustic smell.

The other manufacturer was clarified that the number of phenol formaldehyde binders made by them by the stone insulation. So, they can’t harm human health. However, in 1997, the classification of insulating materials was published, where it is indicated that mineral wool has in the composition of dangerous alkaline earth metals, this theory has not been able to refute. Today, many manufacturers make a stone insulation based on the presented binder. And it applies to the 2nd class of the danger of volatile compounds.

Surely many are known that formaldehyde has in its composition high-tech allergens. And in the composition of the plates of the stone wool, this substance is more than 6%. But if you look at the other hand, formaldehyde throughout a person is near. It is present in furniture and even in street air. So it’s impossible to say that the stone wool is environmentally friendly, however, its composition has not yet caused serious harm to anyone.

Comparison with other materials

Before you know the difference between stone cotton and other insulation, you should dig deeper into the technical characteristics of the materials. Stone wool as glass gamble and slag, is a kind of mineral wool. Accordingly, the question is – what is better, mineral or stone wool disappears by itself. Difference only in production technology and used raw materials. Insulation, as part of which there is a broken glass and quartz sand, does not require the use of resinous substances. Accordingly, during installation, the material cries, and small particles can get into the respiratory tract of the person.

Insulation of clay and carbonate, which is a waste of the metallurgical industry, can not be used inside the residential premises. This material is toxic, can cause allergies. Basalt insulation is made only from natural materials that do not harm human health. Further is invited to familiarize yourself with the clear difference between the stone and mineral insulation. Don’t forget about such a kind of insulation like a penurix.

This material is a product of synthetic origin, which is already felt the difference between stone wool. Well, the cost of the polyplex is much lower than any of the variety of mineral wool.

Varieties

According to the criteria for invoice, form, composition and fitness, stone wool is divided into several varieties.

  • Soft. This material is made of thin fibers. They form many cavities, inside which air is held, which is an obstacle to heat loss. Soft cotton wool is used when insulation of points that do not involve serious loads. Speaking with simple words, it can be used as the shelter of facades and roofs.

  • Average rigidity. In this case, the manufacture of stone wool uses more rigid fibers. This material can be used in the insulation of the facades where strong air flows are present.

  • Hard. In this variety of stone wool, thick fibers are used. Such plates are designed for greater load. Stacking can be produced under the tie and inside the walls.

Soft stone cotton wool sold in the form of a rolled twist, and varieties of medium and high stiffness are made in the form of plates. Some builders claim that with a wool in rolls is much more convenient to work. And others are confident that the plates are more comfortable for mounting.

To date, another variety has been developed, namely the foil stuffing stone wool. The presence of foil provides a double warming property. Speaking with simple words, a foil variety leaves warmly behind its limits and reflects it, directing warm air inside the room.

This type of insulation may have both one-sided and bilateral foil, due to which it refers to the list of universal insulation.

Marking

Do not forget that stone wool, like any other building material, has its markings. The main difference between each individual brand lies in the density of the insulation. From here the difference of properties is viewed.

  • P-75. This brand of stone insulation is characterized by minimal density and is designed to cover horizontal planes with low load, for example, the attic.

  • P-125. This marking is designed for the insulation of interior walls, partitions and ceiling overlap. But the main thing is that the air contained inside the material is enough to block outsiders and keep heat.

  • P-175. Stone wool of this labeling is distinguished by increased density. It is used for the insulation of reinforced concrete floors. According to external data, VATA P-175 resembles a slab made of wood chips.

  • P-200. This marking is characterized by maximum density and rigidity. On each cubic meter of the material assumes a load of 200 kg. But, unfortunately, this material has several minuses. Because of the maximum density, noise insulation indoors becomes low, and the thermal conductivity leaves much to be desired.

Dimensions

To date, stone wool plates are presented in the most allowable sizes. The required dimensions are determined by the ratio of length and width, for example, 100×50 cm or 120×60 cm. The minimum thickness of the stone insulation is 10 mm. There are also options for 20, 30, 50, 100 and 150 mm. The choice of thickness depends on the free space in the walls and other floors requiring insulation.

Scope of application

Stone wool is a modern insulation that enjoyed greatly popular in the construction of new houses or overhaul of apartments. It can be used in the arrangement of not only residential premises, but also for the insulation of economic supplies. Stone Vata is the best facade insulation. Its thermal insulation properties guarantee the prevention of heat loss in the cold season and the conservation of coolness in the heat. In addition to the arrangement of a warm facade outside, stone cotton can be used for insulation of walls from the inside. Only from above will have to apply layer plaster.

Stone wool is also used as heat insulation. It is laid out the basis of the floor covering, after which he filled with a screed. It can also be used to insulate the balcony.

When insulating the roof or roof, be it flat and scanning option, it is recommended to use stone wool in a combined form. But the partitions inside the rooms should be covered completely. Stone wool you can cover columns, reinforced concrete floors, furnaces, air ducts and chimneys.

What is noteworthy, this material guarantees fire safety and has a multitude of universal properties. It also features a high level of noise insulation, which is due to the arrangement of recording studios. In addition to home arrangement, the stone insulation can be used in the bath. This material will not only retain heat indoors, but also will be a barrier for the occurrence of microelline.

Manufacturers

To date, many companies are engaged in the production of stone wool. But not all of them are ready to provide a certificate of conformity and guarantee the quality of the manufactured product. In order not to choose a bad material, it is recommended to familiarize yourself with the ranking of the best manufacturers of stone insulation.

  • “TEKHNONIKOL”. Due to the high quality of products manufactured, this company received recognition in many countries of the world. Special attention brand is paying for the creation of stone wool. On sale This product enters the series. For example, rocklaight, heatpower or technoacoustik. Each separate series has its advantages and relevant price.

  • Isover. French Building Materials Manufacturer Offering Customers Different Line Created Stone Wool. Samples of Isover Classic, Isover KL-37 and Isover KT-37 are widely popular. And the price of the product fully depends on the density of the material and the required number.

  • Rockwool. Well-known brand engaged in the production of high quality building materials. Stone insulation of this company is distinguished by strength, durability, and most importantly – the best heating power.

  • Knauf. The represented brand of the world name is engaged in the production and implementation of building materials of various types and directions. The range of the company is filled with a wide variety of insulation, where a huge value is attached to a stone cotton. This manufacturer has made a lot of effort to enrich its range of different types of stone insulation. And this diligence appreciated the fans of heat and comfort of residential premises.

FEATURES OF MONTAGE

Having understood with the peculiarities of stone wool, we suggest familiarizing yourself with the way it is mounted. And start with the technology of insulation of the outside of the house. This work requires the observance of a clear sequence of actions. Heater sheets, laid on the outside, need to be fencing from wind exposure. For these purposes, glass jammed flooring, chipboard or fibroplitis fit.

  • Initially, it is necessary to clear the working surface from the reinforcement, nails and other protrusions capable of damaging insulating cotton wool. At the bottom of the wall should be installed metallic cornice. The same mount is screwed to the ceiling. First, Vata will fall smoothly. Secondly, it is a serious protection against rodents.
  • The facade of the building should be projected. This is necessary to increase the tensile strength between surfaces. Then glue is applied on the back of the wool. After pressed to the projected working surface in the direction from top to bottom. As an additional fastener, you can drive in plastic dowels. When laying the plates, it is necessary to follow so that they are firmly shaken.
  • A windproof material is stacked over the stone wool, and the ground is applied on top.

This is where it is proposed to familiarize yourself with the process of installing insulation indoors. In this case, the prerequisite is the presence of a metal crate. If suddenly, wooden rails were used to create a crate, they need to be lacquered. The distance between the walls and the stone cotton must be no more than 2 cm. This is necessary to create an additional air layer. To remain the required distance from the wall to the surface of the insulation, the glue should be applied with a solid layer, but.

In the process of work, you will probably have to cut the insulation. To do this, use a sharp knife or hacksaw. Apply for cutting power tools meaningless. After installing the insulation, it is necessary to begin the arrangement of vapor barrier. It is attached to the guides with the help of bilateral scotch. The last stage of work – finishing. Prepared insulated surface is trimmed with drywall, then put off, and after the first cleaner is made.
