How and what to insulate the house from the outside
Statistics show that about 40%energy spent on heating / cooling of buildings. Strange, because today people live in the modern world of advanced, so why throw the budget into the wind, because you can go radically different way and warm the house. Question: how to insulate the house from the outside is not too concerned about the urban population, but it is very relevant for private owners. Typically the additional wall insulation high-rise buildings is not carried out, and the private house and the wooden house needs proper insulation. Therefore, this issue will be considered in the article.

Warm house - a fortress
Earlier, in the last century, the concept of home-fortressIt meant building with thick walls and a half meters, look out the window, and there you can see the street, as if at the end of the tunnel. Houses were built so not because of full combat readiness, so that the then architects wanted in this way retain heat and use less wood for heating. Just before more effective heaters were not, then that's served bricks and insulation, and construction materials.
And today it was a kind of "separationlabor ": brick house is responsible for the strength and the heat stored special heaters. They contribute to the creation of comfortable conditions in the premises, as well as protect the walls from temperature fluctuations and extend the life of the building structure. The idea of selecting a heat-insulating material such: it is better to invest in high-quality thermal insulation of external walls and in the cold time of year to spend less thermal energy and money than heat the street for decades. The prospect of a good, that's just you need to have certain information, and to realize how warm the house in each case.
Analyzing the experience of countries with high living standards,it can be concluded that to reduce the heat loss can be by means of insulation of the building envelope: walls, roofs and windows. They shield the house from various atmospheric phenomena - low temperature, wind, humidity, solar radiation.
Outside or inside?
How warm the house correctly: Yet outside or inside? This question is raised by many people who have decided to make your home more efficient and comfortable. At first glance it may seem that the insulation inside more acceptable, but this is a misconception. Experienced builders such way of warming say a firm "no." You can bring sound arguments to this categorical position. Of course, there is no doubt that the heat-insulating material, padded inside, make the house warm and cozy, but it's not the best solution to the situation. The fact that in such positions the outer walls remain out of work and do not take part in the conservation of heat, and in fact could and "work."
Another unwanted fact - at the crossroadsheaters will produce a temperature drop and as a result, the accumulation of condensation, which adversely affects the service life of the heater and the wall of the building. Also will be created favorable conditions for the formation of a very unpleasant fungus. So, if and to insulate the walls, the outside only.
Advantages of external insulation
They can say and significant challenges:
- A layer of insulation sees sharp fluctuations in temperature, and hence, the term structure of operation increases, the walls are less amenable to deformation;
- You can choose the appearance of the facade, even when the house is completely built;
- In no way limited to the choice of finishes of rooms;
- The opportunity to spend a long time warming erected house;
- The immutability of the interior space;
- When carrying out external insulation interior spaces are not affected in the house you can live in a familiar environment.
Methods of insulation of walls from the outside
Today used three variants of warming the house, each has its own characteristics and advantages.
Location of thermal insulation in the "pit"
The insulation material is placed insidewalls, i.e. between the wall and the layer of lining material, for example, bricks. It turns out that a thermal insulator if trapped inside the wall. This three-layer system is good, but that's just not suited for already built homes.
"Wet" insulation with bonding
A layer of insulation material is glued directlyon the wall, and then additionally fixed with dowels. On top of the insulation is applied reinforcing mesh, as well as multiple layers of coatings: reinforcing intermediate protective and decorative. This method requires professional craftsmanship and faultless performance of the entire process.
The ventilated facade system
In principle, this system is similar tokolodtsevoy masonry, that's just as outer walls used a variety of facing materials (sheet, plate). Insulation fixed to the wall with the frame and the anchor system. It is the most popular method of insulation of town houses as exterior sheathing options are many home - vinyl siding and the ground, panels made of ceramics.
Powerful advantage of this technology isthat can be quite easy to get to the insulation layer, it is enough to remove several panels if necessary. Plus, you can apply this method and for houses where no insulation was planned. Ventilated facades are installed on the brick walls, and wooden and concrete surfaces.
Basic requirements for thermal insulation materials
The works on warming homes must be comprehensivecharacter, choice of insulation depends on the material from which the building is constructed. For example, better insulate the outside of the house, built of brick? Here the answer is simple - the foam, and as the house of wood, it is more suitable mineral wool. Of course, this is not the ultimate truth, as each heater has its own strengths and weaknesses.
The main characteristics that need to be considered when choosing the material, as follows:
- water vapor permeability;
- hygroscopic - the absorption of vapor from the air;
- thermal conductivity;
- fire resistance and fire resistance;
- chemical resistance;
- hydraulic conductivity;
For example, polystyrene has almost ideal characteristics, but still there is one major drawback - the high flammability and release of ethylene, harmful to human health.
A mineral insulating materials have good performance flammability, chemical stability, hygroscopicity and a high degree of sound insulation.
The main thing you need to strive to createsound insulating design, then we can avoid such undesirable things as excessive moisture penetration mice, as well as increased strength, durability and resistance to fire.
Warming of the wooden house
How to insulate wooden house outside and make itwarm and beautiful? It is best to insulate a house made of wood with mineral wool: it's light, well-kept warm and not at all expensive. It is soft and elastic material, which is easy to style, moreover it is not affected by thermal deformation and do not arise cold bridges. After the insulation lining material available at home, which is more like it. This can be boarding, with the appearance of the building will be traditional, but you can use a plastic siding and eventually get a radically new and modern exterior of the house.
Vapor barrier required for buildings of wood
Warming of the wooden house begins withvapor barrier. It can be used as an aluminum foil, plastic wrap or a special film-paroizolyator. The main task of this process - ensuring ventilation of the facade. In case of round logs home, this is no longer a problem, and if the surface is smooth, the stuffed vertical slats, and on them is mounted a vapor barrier.
Important: be sure to between the base rails on top and bottom is necessary to make holes for ventilation - 20 cm in diameter.
Places vapor barrier material fasteners (staples, nails) are sealed with tape, so that the water there did not act.
The framework - a basis for thermal insulation systems
From boards - thickness of 40-50 mm, width 100 mm,It carried out a framework for a heater. Stuffed wall boards vertically, on edge, so that the distance between them is a few centimeters smaller than the width of the insulation.
Important: undesirable to use more thin boards, as they will serve as an attachment for the liner.
Insulation - the next step
Plates of mineral wool installed betweencarcass boards without leaving cracks and gaps. Mineral wool is placed in two layers (each 50 mm) as follows: the joints of the first layer to be aligned with the middle of the second plate. Mineral wool - a semi-rigid and elastic plates, so they are held between the planks without additional fixing, that is, they do not slip.
Laying the waterproofing layer
The heat insulating layer is covered with waterproofing film, which should be free flowing steam and retain water well. This film is nailed or stapled to the frame.
Important: it is desirable to leave the joints overlap of 5-10 cm, and the sealing joints self-adhesive tape.
Frame - a second layer
On board with the insulating layer (topwaterproofing) stuffed rack - width 50 mm, thickness 30 mm. This is done in order to ensure free circulation of air between the insulation and cladding. This means that condensation and moisture that reaches the waterproof layer will be dried. At the bottom of the space with closed metal grid (required thick), this measure is necessary to protect the walls from the entry of insects and rodents.
Siding - finish
At this stage of the tree house insulationcompleted, the final lining for the most part performs a decorative function. That is why the choice of cladding material - a matter of taste and personal preference.
It should also take into account the increasedwall thickness - about 20-25 cm, respectively deepened existing doors and windows. For this reason it is necessary to consider the protection of a warming system on the part of the window openings.
Proper execution of all phases of work on theinsulation provides a good temperature in the house - warm in winter, and in summer - cool. A Controlled installation and configuration, you can be sure that the insulation will be long and to faithfully serve, and for a comfortable stay no longer have to pay extra.
