The problem of heating homes facing humanity with the oldest long. Of course, modern materials allow to reduce heat loss from buildings, but they do not have the opportunity to give 100% result. In order to reduce heating costs, many prefer without the help of others to warm their homes.

Facade insulation serves two goals at once. First of all, is saving, and secondly - additional outer finishing. Qualitatively, the equipped insulation will help keep the heat in the building and at the same time it protects the wall from the impact of natural factors. Many bought services from the insulation in order companies, but such an option is necessary to spend, so that others prefer to do it yourself.
The choice of insulator
The first step in the process is the choice of insulation insulator. Many at this stage make a mistake and use all the same material. Meanwhile can preserve, if installed on different walls insulation of different thickness. For example, on the south side insulator layer may be thinner, but it should be on the corners increment.
The most widely used two materials received today: mineral wool and foam.
Mineral wool - fiber material, inorganic. It is now widely used for the creation of ventilated facades (wet method). The material can withstand temperatures up jumps 1000 градусов, characterized by a high heat-insulating properties, and a well sovladevaet mechanical impacts. Mineral wool does not absorb water and allows you to create excellent sound insulation. service life - up to 40 лет.
Thermal insulation characteristics of the material provided by the creation of technology, during which there is a lot of small bubbles. Таким образом, material comprised almost entirely of air, which ensures its low weight. Particularly attractive in the insulation due to its own price. Average, heat loss from the house, sheathed foam, reduced by 70%. It does not contribute to combustion. not recommended, if there are problems with rodents.
It is important to properly prepare the wall before starting work. First thing they removed all the speakers design, outdoor units Kondyukov, rain gutters, lighting, etc.. You should also remove and passing along the walls of communication.
All work should be created during the warm period, the outside air temperature must be within 5-25 degrees of heat, and the humidity in the area to stay 80%. After the end of each stage should ensure that, surfaces are protected from rain and direct sunlight. To ensure it can be, for example, polyethylene film.
Following you need to check the walls for strength with the assistance of tapping. Then, using the level or plumb find local irregularities, that marked. If there are strong projections or depressions, there are problem areas, they should be in their ability to correct. Since the wall surface is removed and mold fungus, remove oil paint, if available. Cracks and potholes over 2 mm primed and sealed with. The greatest cavity after smoothed pieces of insulation.
After leveling the surface of the wall can move on to the primer, and after it - to a specific warming.
The socket profile
Work start point to determine the lower surface of the insulate. After that, it is transferred to the building corners and connect the mark coated cord, thereby obtaining the starting line. Markings on set ground profile. It will keep the lower number of heat insulation plates, because he has too strong a motion of.
The width of the starting strips should correspond to the width of the insulator layer. It is mounted with dowels in increments of 30-35 cm. If nails are used for mounting, they wear washer. Connections are made at the corners of oblique slices or special connectors.
Installation of window sills
Experts recommend taking care of the window sill before installing insulation. Fixing tide carried to the window, Takeaway is on insulator thickness + 1 cm. If the window is mounted on the starter profile, the cavity is filled with a heat insulator under the windowsill with a mixture of adhesive.
In a subsequent step insulated outer slopes of plastic windows. Most often it is a distance of about 2-3 cm, but the foam is necessary to take the smallest thickness, since in the process will be more additional layers. We should not cut material, focusing on the wall - the foam should extend beyond the escarpment about 10 mm.
Mounting foam and mineral wool is placed on the adhesive. use it can be within 2-hours after mixing, so its manufacturer engaged directly on the construction site. The dry mixture was poured into the bucket and fill the necessary volume of water. The solution was stirred until a homogeneous mass.
Applied to the insulator plate, the adhesive may in several ways:
- in the case of irregularities wall to 1,5 cm, on heat insulator applied adhesive strip height 2 cm, then in the center add a few beacons;
- In the case of irregularities to the 1 cm, rather it will put a few bands on the perimeter and center.
the adhesive strip width must be 3-4 cm, in general it should cover up 6-% the entire surface of the sheet.
After stickers insulator on the slopes and install window sills begins step installation material on the walls. Modern includes two stages of work: first glued sheets, and after further nailed.
Work should start with the bottom edge, from the starting strips. To work will need a pair of spatulas: big and small. The latter will be used to set the adhesive mass at large. The mixture was overlaid on the heat insulator, and not on rock, thereby more evenly distribute it over the surface.
Fastening sheets carried thereby, to form letters in joints have a "T" therebetween. Therefore, applied together with mixing them in 2-3 cm, then pressed into the surface of the previously defined. Flatness inspect using a spirit level. The distance between the sheets should not exceed 2 mm, should ensure that, to the mixture is not leaked into the seams. The allowable thickness difference at the connections - not more than 3 mm.
The side slopes of doors and windows in any case should not fall in line with the compounds. It is necessary to maintain a distance of at least 20 cm. also fundamentally, that the joint has not come to a junction of different materials.
At the corners of the facade insulation create Teeth. To avoid long respective rows of the vertical plate seam it must be wedged into the surface of the adjacent walls. If necessary, after the corner connection arrangement insulator pruned.
Upon completion of gluing, wait about 3 days, during which the adhesive sets, and the material will sit. Otherwise, the material during the drilling will move away from the wall. Considering that, that the warming of the entire house with their hands immediately, material will hold the sun much longer, it makes sense to create a work in stages, individual sections.
For the fresh wall insulation nail fungus. This type of dowel consists of a plastic circle, the same plastic liner, and nail (plastic or metal), which is driven into the sleeve. It is better to choose a plastic nails, as the railways are more expensive and may create thermal bridges. dowel length should be at 5 cm greater insulator thickness.
Reinforce the sheets at the corners and at the center so, so that for each square meter had 6-8 dowels. Additional attachments are arranged next to the slopes. The number and pitch of the fastening element selected depending on the size of the plates, wind loads and structural dimensions.
Installation is performed as follows: first punch do the proper diameter of the hole. The hole should be at 1-1,5 cm longer than the length of the rod. Otherwise, the due to debris falling to score before the end of the dowel will be impossible. After preparing the holes in the spacer is inserted into it a nail and hammer fist or rubber hammer. If the fungus has not left to drive to the end, get it, and the hole dosverlivayut.
Apparatus reinforced layer
In the last step the device is made from mesh-reinforced layer, which increases the entire structure. Прежде всего, Share of reinforcing material are glued on the corners in the door and window openings, that will allow prevent the appearance of cracks in these places in the future. Patch Size - 20-30 cm.
To reinforce the external parts are used perfougolki aluminum or plastic (produced together with the grid strips). Installation is simple: first place glued, after which it is pressed against perfougolok and pressed with a spatula to heat insulator. If necessary, the corners are fixed with nails, is inserted through the perforation holes.
To strengthen the foam used a special fiberglass mesh, resistant to alkalis. Before starting the reinforcing glued sheets treated hand with sandpaper grater, which contributes to smooth out fluctuations in the joints. Following you need to carefully remove the residual grinding products. The grid is cut into strips of wall height.

Following the surface of the foam layer is applied solution rovnenko, mesh fabric is unwound, It is applied to the wall and a spatula solution vtaplivaetsya. Smooth out the net from the middle to the edges.
On the reinforcing layer is applied directly wet another solution layer thus, to mesh completely disappeared and been viewed by him. A day later layer can be sanded, and a few days, when all completely dry, on the wall is applied to the primer, which will facilitate the application of decorative plaster.
If desired, look at all the stages of the work can be, and video. It is more clearly, so it will help to clarify some points, if need be.
