Today, no one will remember how long mineral wool is used to warm houses and buildings for various purposes. This material is also called stone wool and is offered today by many manufacturers. This insulation is one of the most reliable, which is why it lasted so long on the market. For several decades, the material did not give up its positions.
Which manufacturer's cotton wool to choose
The high quality of mineral wool is also indicated by the fact that it remains popular, despite the fact that today innovative solutions for thermal insulation are coming to the market. Having familiarized yourself with the market of modern building materials, you will be able to understand that the products of the Knauf company occupy a rather large share of it. This supplier makes 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 certainly help you make the right choice.
Description of mineral wool brand "Knauf"
Minvata "Knauf" is also called stone wool and is made, no matter how funny it sounds, from stones. This material is also called basalt wool, in the production of which stones of lava origin are used. They are remelted, and then astringents are added to them . Fibers are formed into rolls or solid slabs.
Mineral wool can be made according to different technologies using different materials. The production process affects the technical characteristics of basalt and mineral wool. The traditional mineral wool is good, but can be afraid of moisture, dust and turn out to be harmful. All these troubles were overcome in the framework of modern production. As a result, it is possible to get an almost perfect insulation.
Minvata "Knauf" is made without the use of formaldehyde and phenolic resins. Almost all negative reviews about the dangers of mineral wool used to be directed precisely to 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 hence 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 mineral wool does not dust. This characteristic is characteristic of glass wool. However, if the mineral wool fibers turn out to be poorly formed, then they can break, which causes dust emission.
Specifications
The thermal insulation described in the article quite easily copes with the effects of temperature extremes. It does not burn and does not deform irrevocably. If you decide to purchase this thermal insulation, you should ask about the 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 can only cope with thermal radiation, however, other heaters can be used for this, which can be combined with mineral wool.
Minvata “Knauf”, the characteristics of which you must have studied before purchasing this insulation, has low water absorption. Of the total volume, the amount of water can be approximately 2%. If you translate this value into simple language, then after the stove is in water for several days, it will absorb only a few percent of the liquid, compared with the total volume of the material. This indicator is insignificant, which made it possible to stand mineral wool on a par with polystyrene foam. For all this, the thermal insulation remains vapor permeable.
Minvata "Knauf", the technical characteristics of which are presented in the article, does not burn and does not heat up. It can only be charred, but only with direct exposure to fire. It is important to pay attention also to density. This parameter may vary. On sale are several varieties of branded insulation.
Technical characteristics of mineral wool "Teploknauf Cottage Plus"
Thermal insulation "Cottage Plus" from the company "Knauf" is offered for sale in the form of plates. Their thickness is 10 cm, and the thermal conductivity is equal to 0.037 W / m * 0, which is true at 10 ° C. This non-combustible material has an airborne sound insulation index of 45 RW (W). The length and width of the material are 6148 mm and 1220 mm, respectively.
Technical characteristics of “Acoustic” mineral wool
This mineral wool “Knauf”, the price of which is 1600 rubles. per cubic meter, used for thermal insulation of communications. The material is flexible enough, which ensures its tight fit and eliminates the formation of cold bridges. Minvata “Acoustic Knauf” is able to maintain its original shape for a long time, which guarantees a high level of sound insulation.
This material is characterized by an increased level of elasticity. This allows you to reduce the level of shock and sound noise up to 1.5 times. Installation of this thermal insulation can be carried out in ceilings and partitions, as well as suspended ceilings.
Reviews of varieties of mineral wool "Knauf"
Mineral-cotton materials from the manufacturer “Knauf” can be divided into two lines:
Each of them is used to solve certain problems and was developed for their implementation. Consumers love the Iinsulation range in that it has exceptional quality. This material, according to buyers, is professional and quite expensive, but has one important advantage - versatility. According to home craftsmen, it is convenient to lay it on a large scale when it becomes necessary to process multiple areas.
The Insulation line has excellent performance and durability. Mineral wool of this type can protect the house for several decades. The manufacturer himself gives a forty-year warranty. This does not mean that after this period nothing will remain from the stove. She will be ready to serve a longer period, but only on condition that the cotton wool was operated under normal conditions.
Minvata “Knauf”, reviews of which should help you make the right choice, is also offered for sale in the Teploknauf line. Consumers like that this insulation is simpler, it can be used for domestic purposes. With its help, consumers decorate country houses and small cottages.
The use of mineral wool as thermal insulation
The mineral wool “Knauf” is insulated by home craftsmen independently. You can use this material for thermal insulation of the facade. The basis of the work can be wet-type technology, which combines facade insulation and decorative plaster. This technique is actively used in places with a cold climate.
As the material of the walls can be:
In the role of plaster, quite often different types of compositions are used. Mineral wool is placed under a decorative wet layer, which makes the structure more robust and helps save money on heating. Stucco can be:
- on a mineral basis;
- silicate;
- acrylic;
- silicone.
After drying, the layer can be painted in any color using facade paint.
Insulation technology
The facade at the first stage is cleaned and freed from unnecessary elements. There should be no metal pins on the wall, because they will be covered with rust. If there is no way to get rid of metal, then decorative plaster should not be used for home decoration. Before installing mineral wool on the walls, install profiles. It is important to securely fasten the slats. Using special glue, mineral wool is installed on the surface. Thermal insulation should additionally be covered with a reinforced layer, which will exclude the deformation of insulation materials. Using a spatula, an adhesive layer is applied to the surface, onto which the reinforced mesh is fixed.
Conclusion
Minvata "Knauf" is made with high quality, so when working with it, the craftsmen will not feel the dust. Additionally, it is not necessary to protect the layer of such thermal insulation. Previously, consumers sometimes refused to purchase mineral wool rolls also for the reason that they absorbed water in large quantities. However, these negative characteristics have been eliminated over time. Today in the manufacturing process, water repellents are added to the fibers that are able to repel water. That is why the mineral wool “Knauf” receives only positive reviews.
