The high quality of mineral wool is also evidenced by the fact that it remains popular, despite the fact that innovative solutions for thermal insulation are entering the market today. Having become acquainted with the market of modern building materials, you will be able to understand that a fairly large share of it is occupied by the products of the Knauf company. This supplier manufactures mineral wool, the technical characteristics of which will be discussed below. If you also decide to purchase the described material, you should also read the reviews. They will definitely help you make the right choice.

Mineral wool "Knauf" is also called stone wool and is made, no matter how ridiculous it may sound, from stones. This material is also called bas alt wool, in the production of which stones of lava origin are used. They are melted down, and then binders are added to them. The fibers are formed into rolls or solid slabs.

Mineral wool can be produced using different technologies using different materials. The production process affects the technical characteristics of bas alt and mineral wool. Traditional mineral wool is good, but it can be afraid of moisture, dust and be harmful. All these troubles have been overcome in the framework of modern production. As a result, it is possible to obtain an almost perfect insulation.

Mineral wool "Knauf" is made without the use of formaldehyde and phenolic resins. Almost all the negative reviews about the dangers of mineral wool used to be directed precisely at the fact that when exposed to high temperatures, the material begins to emit phenol fumes, which are quite toxic.

In the described material there are no harmful resins, and therefore no harmful fumes. The same can be said about the ability to emit dust. It negatively affects the human lungs and irritates the skin. However, most often the mineral wool is not dusty. This characteristic is characteristic of glass wool. However, if the mineral wool fibers are poorly formed, they can break, which causes dust to be released.

The thermal insulation described in the article quite easily copes with the effects of temperature changes. It does not burn and is not permanently deformed. If you decide to purchase this thermal insulation, you should ask about thermal conductivity. For mineral wool, this parameter varies from 0.035 to 0.4 W/m. This indicates a low level of heat transfer. As practice shows, cotton wool does not transfer heat. It cannot cope except with thermal radiation, however, other heaters can be used for this, which can also be combined with mineral wool.

Knauf mineral wool, the characteristics of which you should study before purchasing this insulation, has low water absorption. Of the total volume, the amount of water can be approximately 2%. If we translate this value into simple language, then after the plate has been in water for several days, it will absorb only a few percent of the liquid, compared to the total volume of the material. This indicator is insignificant, which allowed mineral wool to stand on a par with polystyrene. With all this, the thermal insulation remains vapor-permeable.

Mineral wool "Knauf", the technical characteristics of which are presented in the article, does not burn and does not heat up. It can only char, but only with direct exposure to fire. It is also important to pay attention to density. This setting may vary. Several varieties of branded insulation are on sale.

Using mineral wool as thermal insulation

mineral wool knauf technical characteristics

Insulation with Knauf mineral wool is carried out by home craftsmen on their own. This material can be used for thermal insulation of the facade. The work can be based on wet type technology, which combines facade insulation and decorative plaster. This technique is actively used in places with a cold climate.

Wall materials can be:

  • concrete;
  • wood;
  • brick.

In the role of plaster, different types of compositions are often used. Mineral wool is placed under the decorative wet layer, which makes the structure stronger and saves money on heating. Plaster can be:

  • mineral based;
  • silicate;
  • acrylic;
  • silicone.

After drying, the layer can be painted in any color using facade paint.

Insulation technology

Facade at the first stage is cleared and freed from unnecessary elements. There should be no metal pins on the wall, because they will rust. If it is not possible to get rid of metal, then decorative plaster should not be used to finish the house. Before installing mineral wool on the walls, profiles should be installed. It is important to ensure that the straps are securely fastened. With the help of special glue, mineral wool is installed on the surface. Thermal insulation should additionally be covered with a reinforced layer, which will prevent deformation of the insulation materials. Using a spatula, an adhesive layer is applied to the surface, on which the reinforced mesh is strengthened.


Mineral wool "Knauf" is made of high quality, so when working with it, the masters will not feel the dust. There is no need to additionally protect the layer of such thermal insulation. Previously, consumers sometimes refused to purchase mineral wool rolls for the reason that they absorbed water in large quantities. However, these negative characteristics were eliminated over time. Today in the production processwater repellents are added to the fibers, which are able to repel water. That is why the Knauf mineral wool receives only positive reviews.
