Warming of the facade with mineral wool: technology, installation, insulation

Thin walls cause 30-35% of the heat to simply flow through them. Thus, almost a third of the money that is paid for heating is wasted, and if you collect them in a year or two, you get a pretty decent amount, which, if you save, you can start anything: rest by the sea, travel to the country you like, purchase New furniture - lots of options.

But how to save money? Do not sit in a cold house? To start saving, you must first spend - make the insulation of the facade minvate. The technology of this process is quite simple, you can do all your work yourself. The only thing you need to do this is to know how to choose the material, how to handle it, and what the sequence of work is. Further about this and much more in more detail.

Basics of choice

But that the material really could perform all the functions and keep the house warm, it should only be of high quality. Not all types of insulation, which are currently on sale in the construction market, we can say that they are of high quality. However, there are firms that produce mineral wool that meets all the requirements and has all the necessary properties. This "Beltep", IZOVOL, Paroc and others.

The list of the best manufacturers is headed by Rockwool. It is a branch of a Danish company. And he is not alone: throughout the country there are factories of this brand that offer high quality products without price wraps.

Insulation Characteristics

Minvata "Rockwool" - one of the best materials, which is characterized by a number of enhanced characteristics. The most important of these are:

1. Excellent sound insulation. Due to this, the fibers are chosen to improve the acoustics of the rooms, the production of noise shields.
2. Low thermal conductivity.
3. Environmental compatibility, which confirms the certificate EcoMaterial Green.
4. Water vapor permeability.
5. Refractoriness - mineral wool can withstand temperatures up to 1000 degrees Celsius, while in other manufacturers this figure is 600 degrees. In the fire, the fibers do not shrink, so very dangerous voids are not formed inside the high temperature.
6. Ease of installation.
7. Possibility to choose an outer insulation in rolls or plates.
8. Durability. Moreover, during the operation, the fibers are not destroyed, they do not deform, they keep the dimensions well.

In addition, what is very important, the Rockwool heater does not rot, it is not affected by rodents and various microorganisms.

Product overview

The company "Rockwool" produces several brands of mineral wool. Among them the most popular:

1. Wentirock Max. It is a mineral wool in the form of mats, intended for use in the insulation of enclosing walls, high partitions and external walls with subsequent facing in the form of glass, stone, corrugated board. The cost of Wentirock Max minivat - from 600 rubles. For 1 square. M with overall dimensions of 100 x 60 x 10 cm.
2. "Conlit". This name is worn plates and shaped products. Available in two versions - with aluminum lining and without it. Some products are finished with a layer of fiberglass. This type of products is designed for installation on sites that are subject to increased fire safety requirements. To fix the plates "Conlit" on the surface to be coated, you will need to additionally purchase the adhesive specially designed for this purpose.
3. Light Batts. These are lightweight waterproof heat-insulating slabs that do not shrink and are easily mounted. The cost of "Light Batts" minivates depends on its thickness (5 or 10 cm) and plate sizes and varies from 450 to 565 rubles.

In total, the manufacturer produces 24 types of insulation, which allows you to choose the most suitable option for a particular purpose.

Material selection

Before you buy your favorite mineral wool, be sure to pay attention to where it will be installed and whether it is intended for this. So, if the installation of mineral wool is carried out outside the building, then the material should be facade, because it has a higher hydrophobicity, repels moisture and has a good density. A heater intended for indoor installation has lower properties and can not cope with its intended purpose if installed outside the building.

Unfortunately, the minivate, like any building material, has not only merits. He also has disadvantages - the need to strictly follow the technological process. If the manufacturer's recommendations for installation are violated, the insulation will lose its thermal insulation properties. One of the variants of the technology violation is the rejection of the reinforcing layer. Such a solution will lead to the fact that the facade will appear, and eventually spread the cracks.

Thermal insulation technology

Experts advise very carefully and seriously to take recommendations for the installation of insulation and properly prepare the walls - only this guarantees the quality of the result, and the process itself will not take much time. How should the facade be insulated with mineral wool? The installation technique consists of several stages. It:

1. The product of the markup.
2. Setting the profile.
3. Installation of insulation.
4. Fixing of insulating material.
5. Reinforcement.
6. Waterproofing maintenance.
7. Finishing of surfaces.

After marking, it is necessary to remove cement stains from the walls, protrusions sticking out metal pins, and then remove wires, drain pipes and other objects, so that eventually rust from them does not appear on the surface of the facade. Then all the cracks should be sealed with a solution. After this, it is necessary to apply a protective agent against the fungus all over the insulated surface. And it needs to be done, even if the fungus on the wall surfaces is not noticed. If the walls are wooden - they need to be impregnated with an antiseptic.

Preparation of the facade

Warming of walls with mineral wool is carried out in the following sequence:

1. Priming the walls. And it is necessary to use a material that penetrates deep into the surface of the walls.
2. Mounting the guides. It can be wooden beams or a metal profile. Horizontal guides should be of the same thickness as the thermal insulation material. Given that the mineral wool can be squeezed slightly during installation, the profile can be used thinner by 1-2 cm, it is quite acceptable. The distance between the rails depends on the size of the slabs.
3. To ensure that the plates are packed tightly, without gaps and slots, the distance between the guide rails needs to be made slightly smaller. But this figure should not exceed 2 cm.
4. Fix the guides using self-tapping screws or dowels.
5. Lay the Rockwool heater between the rails. Begins laying from the bottom and ends at the top. You can put the heater on the glue or strengthen it with dowels. If there are still gaps between the thermal insulation material and the guides, they must be filled using the remnants of the insulation.
6. To reinforce the insulated wall on its surface, it is necessary to apply glue and gently press the reinforcing mesh. Then, the adhesive must be applied again from above. This will prevent deformation of the surface and will additionally protect the insulation from moisture.

Mounting under siding

If the siding is used as the final finish, it is best to arrange a ventilated facade, performing the insulation of the facade with mineral wool. The technology of this action is as follows:

1. Secure the vertical profile. All elements are installed at a distance of 40-50 cm from each other.
2. In the interval between the vertical columns, Minvata "Rockwool" is laid, which is fastened with plate dowels.
3. The waterproofing membrane closes the heater. Joints are glued with butyl tape. This must be done to protect the insulation from moisture. Depending on the material of the walls, clamps or liquid nails are used to fix the vapor barrier film .
4. Installing the control unit.
5. Installation of siding.

Warming for plaster

Warming of the facade with mineral wool under the plaster eliminates the use of steam-and-wind insulation and crates. The works are carried out according to the following plan:

1. To fix on the surface of the facade minivat, using for this glue or poppet dowel. It should be ensured that no gaps remain, and the joints of the next row of plates are located approximately in the middle of the previous row.
2. Mounting reinforcing mesh. Cloths are stacked with an "overlap" of 10-15 cm - this will not allow the cracking of the plaster.
3. When the reinforcement layer becomes dry, an exterior finish is performed.
4. Using a spatula, remove the adhesive streaks.
5. If it turns out that the reinforcement did not level the wall surfaces, you can first use the rough plastering
6. Carry out the final lining. To improve the aesthetic properties of the building it is desirable to use decorative plaster.

Tips from specialists

Those who are engaged in construction professionally, say that it is possible to conduct the warming of the facade with mineral wool itself. The technology is not complicated, but there are some nuances, without knowing which to perform the work at a high level will not work:

1. For outdoor installation, the "Rockwool" mineral wool in the slabs is best suited - this material has a high density, so in time it will not sag.
2. It is best to take a warming material of such thickness that it can be installed in one layer. If the installation is carried out in two layers, the seams should not coincide.
3. During installation, care should be taken that no voids remain - they will be bridges of cold, provoking condensation.
