Minvata Knauf: description, specifications and reviews

Today, no one will remember how long mineral wool is used to insulate houses and buildings for different 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 in the market. For several decades the material did not give up its positions.

Select which producer to choose

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

Description of Knauf mineral wool

Minvata "Knauf" is also called stone wool and is made, no matter how ridiculous it may sound, from stones. This material is also called basalt wool, in the production of which stones of lava origin are used. They are melted down, and afterwards astringents are added to them. Fibers are formed into rolls or solid slabs.

Mineral cotton wool can be manufactured using different technologies using different materials. The production process affects the technical characteristics of basalt and mineral wool. Traditional mineral wool is good, but can be afraid of moisture, dust and harmful. All these troubles were overcome in the framework of modern production. In the end, you can get an almost perfect insulation.

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

In the material described, there are no harmful resins, and hence no harmful vapors. The same can be said about the ability to release dust. It affects the lungs of a person and irritates the skin. However, most often the mineral wool does not dust. This characteristic is peculiar to glass wool. However, if the fibers of mineral wool are not well formed, they can break, which is the reason for the release of dust.

Specifications

The thermal insulation described in the article quite easily copes with the effect of temperature changes. It does not burn and does not deform irrevocably. If you decide to purchase this insulation, then you should inquire about the thermal conductivity. In 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 not cope with heat radiation, but other heaters can be used for this, which can also be combined with mineral wool.

Minvata "Knauf", the characteristics of which you should be studied before purchasing this insulation, has a low water absorption. The total amount of water can be about 2%. If you translate this value into a simple language, then after the plate has been in the 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 to stand mineral wool in a row with foam. With 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 char, but only with direct exposure to fire. It is important to pay attention also to the density. This parameter can be different. Several types of branded insulation are on sale.

Technical characteristics of mineral wool "Teploknauf Cottage Plus"

Thermal insulation "Cottage Plus" from the company "Knauf" is offered for sale in the form of slabs. Their thickness is 10 cm, and the thermal conductivity is 0.037 W / m * 0C, which is true at 10 ° C. This non-combustible material has an airborne noise insulation index within 45 RW (W). The length and width of the material are 6,148 mm and 1220 mm, respectively.

Technical characteristics of the mineral wool "Acoustics"

This minivat "Knauf", whose price is 1600 rubles. Per cubic meter, is used for thermal insulation of communications. The material is flexible enough to ensure its tight fit and exclude the formation of cold bridges. Minvata "Acoustik Knauf" is able to retain its original form 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 insulation can be carried out in floors and partitions, as well as suspended ceilings.

Reviews about varieties of mineral wool "Knauf"

Mineral wool materials from the manufacturer "Knauf" can be divided into two lines:

• Insulation;
• "Teploknauf".

Each of them is used to solve certain tasks and was developed for their implementation. Consumers like the Iinsulation line in that it has exceptional quality. This material, on assurances of buyers, is professional and rather expensive, but it has one important advantage - universality. According to home-made craftsmen, it is convenient to stack it large when it becomes necessary to process multiple areas.

The ruler Insulation has excellent characteristics and longevity. Mineral cotton wool of this type can protect the house for several decades. The manufacturer gives a forty-year warranty. This does not mean that after this period, nothing will remain of the plate. It will be ready to serve for a longer period, but only on condition that the cotton wool has been used under normal conditions.

Minvata "Knauf", reviews about which should help you make the right choice, is offered for sale also in the line "Teploknauf". Consumers like that this heater is more simple, it can be used for domestic purposes. With its help, consumers work out country houses and small cottages.

Use of mineral wool as a thermal insulation

Warming of mineral wool "Knauf" is carried out by home masters independently. Use this material for thermal insulation of the facade. The work can be based on wet-type technology, which combines a facade insulation and decorative plaster. This technique is actively used in places with a cold climate.

The following can be used as wall materials:

• concrete;
• wood;
• brick.

In the role of plaster, quite often different types of compositions are used. Mineral cotton wool is laid under a decorative wet layer, which makes the construction more sturdy and contributes to savings on heating. The plaster can be:

• On a mineral basis;
• Silicate;
• Acrylic;
• Silicone.

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

Thermal insulation technology

The facade is cleaned at the first stage and freed from unnecessary elements. On the wall should not be metal pins, because they will be covered with rust. If metal is not possible to get rid of, then for finishing the house should not use decorative plaster. Before installing the mineral wool on the walls should be installed profiles. It is important to ensure reliable fastening of the strips. Using a special adhesive, mineral wool is installed on the surface. The thermal insulation should additionally be covered with a reinforced layer, which will eliminate the deformation of the insulation materials. Using a spatula, a glue layer is applied to the surface, on which reinforced mesh is reinforced.

Conclusion

Minvata "Knauf" is made qualitatively, therefore at work with it the masters will not feel a dust. Additionally, there is no need to protect a 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 process, water repellents are added to the fibers, which are capable of repelling water. That is why the minat of Knauf receives only positive feedback.
