High soundproof and heat-insulating characteristics, as well as moisture resistance and fire resistance make mineral wool products indispensable for the construction of objects of various values. A modern alternative to insulation is ecowool.

Thermal conductivity of mineral wool

Mineral wool is a heat-insulating fibrous material that is obtained by melting metallurgical slags, rock silicate rocks and their mixtures. Thermal insulation boards are made of such material for construction projects, which can be used in external and internal insulation systems. If necessary, some types of thermal insulation are installed under stretch, plasterboard or suspended ceilings. Its properties make this material irreplaceable and widely used.

Due to the raw materials used for production, mineral wool is divided into slag and stone wool. In the latter case, such rocks as diabase, dolomite, basalt and limestone are used, and in the first case, slags (industrial metal waste). Raw materials are exposed to excessive heating with further formation of mineral fibers by centrifugal or blowing methods. The melt stream is influenced by centrifugal force, compressed gas or water vapor, resulting in the finest fibers, which are subsequently pressed. The resulting mineral wool has an increased sound and heat insulation capacity, moisture resistant and non-combustible.

Thermal insulation characteristics and properties are based on reduced thermal conductivity. The orientation of the compressed fibers plays an important role in this: the scattered arrangement guarantees better thermal insulation, however, the vertical position helps to create a lower density board while maintaining increased strength. Non-combustibility allows its use in the form of fire insulation, since products made of such a material effectively prevent the spread of flame and do not emit harmful and toxic substances under its influence.

Mineral wool - good sound insulation

Mineral wool is a fibrous thermal insulation material based on a synthetic binder, which is obtained from mineral raw materials. Basalt is the basis for the production of mineral wool. Mineral wool is a material with a low thermal conductivity. The average fiber thickness of the mineral scraper should be the minimum possible for a particular technology. The content of air pores and channels should be up to 95% of the cotton wool volume.

The thermal conductivity of air in a stationary state of mineral wool is very low, which allows it to be used in many areas and increases the efficiency of the material in construction and other areas.

URSA insulation is used to insulate walls, roofs, houses, floors, and facades. You can buy URSA thermal insulation here. URSA is a modern material that is stone wool formed by extruding polystyrene that is exposed to high temperature and pressure.

The following are the benefits of URSA isolation:

  • low thermal conductivity;
  • durability - it is almost not subject to wear and tear, its service life lasts for decades;
  • increased strength - the slabs hardly deform and withstand a load of 150 kPa for 20 years;
  • zero water absorption;
  • increased frost resistance;
  • environmental friendliness of the product;
  • biological resistance;
  • fire resistance - the material belongs to the G1 class, that is, it is difficult to combustible materials.

The sound insulation characteristics of mineral wool are also achieved due to the structural features of the insulating product. Sound waves are not created between the chaotically located fibers. The material receives its water-repellent characteristics by means of impregnation with special compounds, which, if necessary, makes it possible to carry out insulation work of objects even in rainy and damp weather.

Heat-insulating mineral wool products are used in heat-insulating multilayer systems, among which it is worth noting external insulation of a "wet" look, insulation of the internal walls of the structure (sandwich panels, three-layer reinforced concrete or concrete panels, laminated masonry), an insulating layer in ventilated curtain facades.

At those facilities where insulation is stressed during operation or during installation, rigid mineral wool heaters are used, which are also used for thermal insulation of basement buildings and in floor systems, not only insulating it, but also significantly increasing the sound insulation properties of floor ceilings.

Such slabs are designed for use for surface insulation without reinforced concrete screed or metal profiled flooring. For the most effective thermal insulation, the contact of the mineral wool with the surrounding air should be avoided.

Mineral mats are used for thermal insulation of heat carriers in road communication systems, as well as for insulation of equipment and pipelines of industrial enterprises. In addition, mineral wool mats are used to insulate rooms with increased environmental requirements.

Mineral wool is a filling material for sandwich panels. It is laid between the walls of the panels so that the position of the fibers is vertical, which in turn gives the panels additional rigidity and ensures their increased thermal insulation qualities.

High water resistance and fire resistance, low thermal conductivity, as well as the durability of mineral wool make it an indispensable product for sound and heat insulation of pipelines, industrial premises, residential buildings, and other objects, for these properties it is so popular. Today, mineral wool mats, slabs and other products are firmly at the forefront of efficient and environmentally friendly thermal insulation materials.

There are general rules that experts recommend when working with such material.

Mineral wool - useful tips for use

Strict adherence to the instructions on the packaging will avoid unpleasant mistakes and rework. Cutting of such material is carried out using a special knife.

When working with such material, you must pay attention to the fact that its edges are not torn and frayed.

From time to time, the material must be laid in several layers in order to obtain the desired thickness of the thermal insulation layer.

Mineral wool should adhere well to the surrounding structures. For a high-quality effect, the insulated space must be completely filled.

The alternative is Ecowool. What it is?

Ecowool is a modern insulating material that is in great demand among buyers and is gaining more and more popularity. Why is it chosen, what are its advantages and disadvantages?


Outwardly, it is a rather loose mass of gray color. It belongs to the category of cellulose insulation intended for insulation work during construction. In the production, they use ordinary waste paper, which serves as the basis. The process of making ecowool itself is quite simple and the business of manufacturing it is gaining more and more popularity. Along with the undoubted advantages that consumers speak positively about, ecowool has certain disadvantages. These include low density, which makes it impossible to use, for example, when laying floating floors. You can also not lay it as a heater in complex structures by hand, special equipment is required. The disadvantage of dry styling is that it is very dusty.


On the other hand, the advantages of this material outweigh its disadvantages and should be discussed. The first thing the consumer pays attention to is the efficiency of ecowool in comparison with everyone else. Building materials presented on the market. Molds, insects and rodents will not grow in this material. In addition to its environmental friendliness, it is resistant to fire, has high adhesion to all basic building materials - brick, concrete, glass, metal and wood. It is imperative to remind that it has excellent soundproofing properties, it is easy to work with it. If you have the necessary equipment, then this material fits into the most inaccessible places. The air permeability of this building material is quite low.

Ecowool has a number of unique and specific performance properties that can maximize the scope of this material. In industrial and civil construction, this material is widely used as noise-absorbing and insulating backfill or packing. Ecowool is used in the formation of heat-insulating layers on surfaces with low temperature resistance, in the production of heat-insulating materials for high temperatures. This building material can also be introduced as an additive to asphalt-bitumen mixtures and used in the construction of anechoic-type premises.

Installation is done either manually or using special equipment. In manual operations of laying ecowool, you must first loosen it as much as possible with the tools at hand, and then lay it out on insulated surfaces, or fill it in the cavity. When laying this material, the requirements for laying density must be observed. For walls, the amount of ecowool should be at least 70 kilograms per cubic meter, and for floors - about 40 kilograms per cubic meter.

With the mechanized method of laying ecowool, blowing machines are used, which first loosen it, and then a stream of air moves the material to the place of laying. This method makes it possible to fill the most inaccessible cavities and gaps, therefore, a continuous layer is laid without gaps. It is also possible to spray, which resembles the method of mechanized laying, only the material is applied using water or glue, which act as a binder. Such a technology for laying ecowool requires the use of a nozzle or a special spray for supplying water and glue under pressure.

The main difference between ecowool and other heaters

Using ecowool or ecowool for insulating your own home contributes to a much more efficient heat retention than insulation, with the same volume of more traditional insulation, such as, for example, mineral wool, basalt (or stone wool), glass wool, isover, etc. When using ecowool, there is a noticeable reduction in financial costs for heating in winter and air conditioning in summer.

A highly effective thermal barrier is created. When insulating a room with ecowool, all voids are filled, and additional protection is created for all other, more flammable building materials. And when it comes to fire safety, a wooden house insulated with ecowool is the safest among the majority of heaters.

Fire retardant as part of ecowool

According to the standard, ecowool contains 100% boric acid - an excellent ideal fire retardant. The borates contained in the acid are natural compounds that are absolutely harmless to humans and used in medicine. Borates are absolutely non-volatile substances and in their composition resemble table salt.

The material does not contain fibers that can lead to allergies on the skin and lungs. When insulating a house with ecowool, there is no concern for the health of all the inhabitants of the house, because the main component of ecowool is recycled waste paper. Other components used in the production - borates are also absolutely harmless to humans. When you insulate your house with ecowool, you do not have to worry at all that the insulation can harm your health and the health of people around you. The same cannot be said about stone wool and glass wool (isover), which constantly split off harmful and sharp fibers from themselves.

Installation is also its superiority over other heaters

Ecowool insulation is blown during installation by a special blowing unit or by manual filling. The material injected in this way completely fills all cavities of the structure, and does not leave voids between electrical wiring, plumbing and other engineering communications hidden in the cavity of the structure. In addition, during wet blowing of ecowool, water “dust” activates the adhesive properties of the material, absolutely without disturbing the composition and properties of the insulation. Ecowool is not afraid of moisture!

The use of this material is gaining momentum, due to its useful properties and characteristics, it is being introduced into many stages of DIY apartment renovation.
