Insulation of the facade with mineral wool - process features Thermal insulation of the facade with mineral wool - technology of work

To save on heating in winter, maintain a comfortable temperature in summer, prevent the formation of fungal colonies and mold, insulate materials will help provide sound insulation.

Mineral wool can be used for this purpose for a long time, and even now has not lost its relevance. Let's talk about insulating the facade with mineral wool.

The main properties of mineral wool

Mineral wool is used to insulate the inside and outside of the building. This became possible due to the following qualities of the insulation:

  1. Low level of thermal conductivity, due to which heat losses are minimal, and in summer the air temperature outside practically does not affect the atmosphere inside the room.

  2. Non-flammable - it can withstand high temperatures, is non-flammable. When smoke is generated, toxic substances will not be released.
  3. Steam permeability - the material can give off steam absorbed into the atmosphere, due to which the reproduction of pathogenic microscopic organisms is excluded.
  4. Sound insulation - the structure of the fibrous type of mineral wool perfectly traps extraneous noise, and also prevents them from getting into the building.
  5. Chemical passivity - due to this, when the metal comes into contact with the insulation layer, corrosion does not develop.

Mineral wool is completely fireproof, has high vapor permeability and excellent water-repellent properties. Before insulating a house with mineral wool, you should study all its advantages and disadvantages, and also determine whether it is rational to apply it specifically in your case.

Advantages

The advantages of the material for thermal insulation are obvious, as they follow from the technical parameters:

  • Insulation of the facade with mineral wool - process features High level of thermal insulation due to low thermal conductivity.
  • Safety for human health due to fire safety and resistance to aggressive substances.
  • Durability due to the high level of strength.

  • Easy to install due to flexible material.
  • Versatility - suitable for surfaces of any kind (aerated concrete, wood, etc.), in addition, mineral wool is used not just for facades, but also for attics and floors.

When choosing thermal insulation materials for a future building, you need to know about all its pros and cons. Based on the advantages listed above, thermal insulation using mineral wool is a very effective method of thermal insulation, which helps to significantly save money.

Disadvantages

Along with positive qualities, mineral wool also has some disadvantages that limit the range of its use:

  • Installation must strictly follow the recommendations of the material manufacturer.
  • Despite the low level of hygroscopicity, cotton wool can absorb moisture, and this negatively affects its quality characteristics, and therefore requires additional thought on waterproofing.
  • The multitude of offers on the market creates the risk of purchasing low-quality products, which are toxic and, therefore, dangerous to human life.
  • Due to the structural features, it is required to carry out insulation work in special clothing in order to protect the skin and mucous membranes.
  • The cost of mineral wool is more than that of polystyrene, but the price is fully justified, since its quality and strength parameters are much higher.

Often the material is used to insulate floors and roof structures. Disadvantages are conditional and when choosing a high-quality insulation material, as well as observing the installation technology, you can achieve excellent results.

Varieties of mineral wool

Mineral wool is subdivided into separate varieties, depending on the raw material that was used in production process:

  • Rocks.
  • Fiberglass.
  • Slag.

Many people are interested in what is better - mineral wool or basalt. Insulation of the facade of the house with mineral wool is the best choice, and basalt is a subspecies of mineral insulation. It is important to understand the differences between basalt wool and basalt. The difference lies in the fact that the basalt itself is a rock, which is only one of the constituents of the heat-insulating material, and cotton wool is a heater. The comparison table will help you to clearly see how the basalt wool differs in terms of parameters and operation from mineral wool.

Mineral wool Basalt wool
Density the material is low, which affects the moisture absorption coefficient, and therefore, to maintain the thermal insulation qualities, it is necessary to additionally lay special membranes. The difference between basalt wool in this aspect is significant. High density helps to increase the thermal insulation parameters, and further increases the service life of the insulation material.
Due to the fact that the material is malleable and easy to transport, it quickly regains its original shape. This insulation is produced in the form of slabs, and therefore the conditions for its use are limited.

Very convenient to install, since soft and long fibers will not crumble and break. Basalt wool is inelastic, and mineral wool can crumble during installation and cause irritation of mucous membranes.

Before the start of the insulation work, you need to decide on the selection of heat-insulating material - mineral or basalt wool. Which is the best of these two materials? it is required to take into account the operating conditions, the required thermal insulation degree, as well as the characteristics of the room that will be insulated.

The best manufacturers

A huge number of mineral wool manufacturers are represented on the construction market.

At the end of the year, the most popular brands were named:

  1. Leader - insulation ROSKWOOL. Products from this manufacturer have a high level of thermal insulation and sound absorption. It is absolutely safe for humans, which will make it possible to use it even for the insulation of public institutions. Its high quality characteristics made it a privilege, and this influenced the price. According to experts, the technical parameters of Light Butts from Rockwool rightfully give it the opportunity to be called one of the best.

  2. TechnoNicol is a leading manufacturer of low-cost material. It is very easy to install, but if you do not follow the installation rules, the sheets may start to break. Basalt wool from the manufacturer has excellent vapor permeability values.
  3. The ISOVER brand is no less popular in the building materials market. The manufacturer offers glass wool and stone wool, which are safe and environmentally friendly.

    The insulating qualities of materials are at a height, while the cost is quite acceptable.

Still, experts single out the following manufacturers, namely URSA, KNAUF and PAROK. Products from such brands are often used to insulate log houses and other buildings. The listed thermal insulators retain heat well and are easy to install. These are quite expensive materials, but their cost is consistent with the quality.

Experts recommend the Beltep brand from mineral wool for the facade in the middle price category. Fire safety, excellent level of vapor permeability, excellent rigidity and ease of installation, combined with an acceptable cost, made the Belarusian manufacturer extremely popular.

When insulation is required

Warming of houses and warehouses outside mineral wool or industrial premises is relevant in regions with any climate. The installation of such a material not only makes it possible to maintain a comfortable temperature level, but also provides excellent noise insulation. Wall insulation outside with cotton wool can be done even under plaster, siding or other methods.

The main thing is that the installation rules are followed in order to achieve the desired result and avoid the shrinkage process.

Tools

Before you start insulating facades with mineral wool for plaster or other finishing method, you need to prepare all the necessary tools:

  • Insulation of the facade with mineral wool - process features Hammer.
  • Screwdriver or screwdriver.
  • Drill or hammer drill.
  • Finishing material.

  • Primer.
  • Membrane type materials.
  • Knife and metallized tape.
  • Hardware - self-tapping screws, screws and dowels.
  • Roulette and building level.

  • Beams made of metal profiles or wood.

If you have everything you need at hand, after choosing a heater of the required thickness, you need to choose the option for finishing the house facade.

Varieties of finishes using mineral wool

Insulation of the facade of the building with mineral wool is carried out for different finishing options. The choice will depend on the features of the building, as well as the personal preferences of the owner.

Wet façade

For a wet façade, mineral wool is ideal as a heater.

The most popular finishing method is considered to be plastering, or wet facade. Thermal insulation of a residential building with mineral wool by this method will ensure contact between walls and insulation. Additionally, using dowels, you can guarantee the strength of the fastening of the material. After plastering, the surface should be subjected to additional finishing.

Ventilated façade

Insulation of the facade of a building with mineral wool using a pre-prepared frame made of a metal profile is called a ventilated façade.

This method provides for the presence of air space between the insulation and the wall, which ensures the drying of the walls, namely, natural ventilation. This option significantly increases the service life of the material for thermal insulation. the peculiarity of the process lies in the fact that the procedure is required only on flat walls.

Facade cladding with siding

Insulation of the facade of the house with mineral wool from the outside is almost always accompanied by finishing by means of siding. This will make it possible to significantly increase the operational life of the timber, while maintaining the external beauty of the building and aesthetics.

For this, you can use any type of panels:

  • Acrylic
  • Metallic.
  • Vinyl.

They perfectly resist the influence of ultraviolet radiation, precipitation, and are also pathogenic to microscopic organisms.

Installation technology of insulation

In order for the thermal insulation to be of high quality, it is required to insulate the facade with mineral wool exactly according to the technology. All processes must be carried out in a clear sequence and use high quality materials for this.

A detailed scheme for insulating a frame-type house with mineral wool will look in a certain way.

Priming walls

It is the primer that helps to ensure perfect adhesion, protect the surface from mold and mildew, and also prevent it from getting inside the walls and steam insulation. It must be applied in a thick layer, and the rest of the processes should be carried out after perfect drying, and the period will depend on the brand of the composition.

Labout

When insulating the walls of a frame house with mineral wool, it is important to first carry out the marking. This will make it possible to fix the material to the maximum evenly.

For marking, a rule and a building level are required. It must be carried out horizontally and vertically.

Installation of the basement profile

This process helps to remove unnecessary stress, protects the material from getting wet and ensures secure fastening. Installation requires fasteners, a drill, a level or even a screwdriver. It is required to carry out the procedure according to the marking, since all the insulation of the frame-type house with mineral wool will depend on how smoothly the strips are fixed.

Installation of plates by means of dowels

For thermal insulation, hardware must be used. They are needed at different stages. With their help, it is possible to carry out direct insulation of the walls of the building with mineral wool, fixing the insulation plates with dowels. In advance in the wall you need to make holes for the dowels, and you must first fix the outer hardware part, and then the central one. The hat should sink a little in the mineral wool, and it is important to hide the recess that appears with an adhesive.

Installation of boards on the adhesive

Wall insulation by means of mineral wool from the outside can be carried out on the adhesive. The diluted solution is required to be applied over the entire sheet surface, additionally smearing the corners. The lower part should rest tightly against the profile so that there are no displacements.
