What material do the insulation of the walls from the outside?
Only here is one of the existing thermal insulation to choose in order that the technology of insulation of external walls was simple, which can be done by oneself and the material itself was not harmful, and the effect was higher than expected. Widely known and widely available mineral wool has both positive and negative reviews of masters, producers stand for this material with a mountain, environmentalists categorically oppose its use.
Therefore, from sin, we will consider something new. For example, such material as peat-and-wood blocks of domestic production is very interesting. You have to independently master the warming of the walls from the outside with your own hands, video instructions can not be found.
But having executed in one layer a covering by the blocks, which dimensions are 500х250х880 mm, you will get a thermal insulation corresponding to a brick laying in the thickness of 2 meters.
Combustible thermal insulation materials, even those that are flammable at a sufficiently high temperature, should be impregnated with flame retardants before use.
If there is good ventilation in the premises, it is possible to cover the walls with foamed sheets, which are foamed polyethylene in a shell of aluminum foil. Their only drawback is absolute vapor tightness. That is, there may be a sauna effect in the rooms, only good ventilation will help out.
Otherwise, polyethylene foam - insulation is excellent: cheap, lightweight, strong and thin enough, it can be fixed with construction staples. The thermal conductivity of this material is one and a half times lower than that of fiberglass and basalt slabs. However, if you want something more familiar, why not make the walls warm with ordinary styrofoam or, simply, foam?
External wall insulation, what you need to remember?
First, let's find out why using only internal thermal insulation gives results that are significantly worse than the external wall insulation that was done by all the rules. You probably heard more than once about the dew point, that is, the area on which there is a zero temperature between the negative external and positive internal. So, in the absence of thermal insulation in general, this very point appears in the thickness of the wall, which negatively affects the properties of the material from which the house is built.
If there is only an inner insulation, the zero mark moves into the depth of its structure, and this means the appearance of condensation under the wall decoration and, often, the development of foci of mold or other fungus. And, finally, as expected, we have the insulation of the outer wall( no one forbids at the same time to cover with thermal insulation and the inner surface), in this case the dew point is moved out of the house, coming to the skin with a heat-consuming material.
Now the wall will not suffer, and the rooms will be dry and cozy. It remains only to protect from condensation materials for insulation of walls from outside, for which when decorating the walls should leave an air gap, as well as if the facing is made of special brick or blocks of building stone, do not forget about the ventilation holes.
Technology of insulation of walls from outside for different materials
Almost all types of insulation are fixed to the walls with dowels, except for glue or staples. Before installing the thermal insulation in the form of plates on the walls, it is customary to prick vertical bars so that later it is easier to fasten the lining. When working with expanded polystyrene it is possible to install the beams directly onto the insulation, they will become additional fixing elements.
Of course, if you intend to plaster the walls, the technology of warming the walls from the outside will be slightly different, the mounting net will be attached to the beam, which is necessary for a good adhesion of the finishing mixture. Non-standard method of insulation - if you use ceramic-polystyrene plates, which are nothing else than high-density foam with pressed into it clinker tiles of German manufacture.
This version of insulation will simultaneously and excellent thermal insulation, and a beautiful decorative coating. Fastening is carried out by 9 dowels in points prepared in advance for this purpose. After mounting the plates, the seams between them are rubbed together. If they have woven polystyrene or mineral wool, and decided to finish the blockhouse, in addition to the fact that all the elements you will be mounted end to end, it is recommended to perform the facing with concentric belts around the whole building, and not on each wall separately.
