Statistics show that about 40% of the energy spent on heating / cooling 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 with urban residents, but it is very relevant to the private owners.As a rule, additional insulation of walls of apartment buildings is not carried out, and private brick and wood house needs proper insulation.Therefore, this issue will be considered in the article.

Warm house - a fortress ↑

Earlier, in the past century, the concept of home-fortress 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, but because the then architects wanted in this way to keep warm and use less wood for heating.Just before more effective heaters were not, and that's served while bricks and insulation and construction materials.

And today was a kind of "division of labor": brick houses responsible for the strength and the heat stored special heaters.They help to create 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 this insulating material 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 a decade heat the street.The prospect of a good, that's only necessary to have certain information, and to realize how warm the house in each case.

analyzing the experience of countries with high living standards, we can conclude that reduce heat loss through the insulation can be 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 to insulate the house from the outside or the inside yet?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 of such a method 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 exterior walls are out of work and did not take part in the preservation of the heat, and in fact could and "work."

Another unwanted fact - at the junction of heaters will produce temperature difference, and as a result, accumulation of condensate, which adversely affects the service life of the heater and the wall of the building.Also will create good conditions for the formation of a very bad fungus.So, if we insulate the walls, and then only from the outside.

advantages of external insulation ↑

They can say and weighty challenges:

- layer insulation sees sharp fluctuations in temperature, and thus increases the life of the structure, walls less amenable to deformation;

- you can choose the appearance of the facade, even when the house is completely built;

- no limited range of finishing rooms;

- the opportunity to spend a long time building the house warming;

- the immutability of the interior space;

- during external insulation interior shall not be affected, in the house you can live in a familiar environment.

methods insulating walls outside ↑

today use three variants of warming the house, each has its own characteristics and advantages.Location

insulation in the "pit» ↑

insulation material is placed inside the walls, that is, between the wall and the layer of cladding material, such as brick.It turns out that if the insulator is locked inside the wall.This three-layer system is good, but that's just not suited for already built homes.

«wet" insulation with gluing ↑

layer of insulating material is glued directly on the wall, and then additionally fixed with dowels.On top of the insulation reinforcing mesh is applied, as well as multiple layers of coatings: reinforcing intermediate protective and decorative.This method requires professional qualifications of performers and flawless execution of all process.

Wet facade

ventilated facade systems ↑

In principle, this system is similar to kolodtsevoy masonry, that's just as outer wall cladding used a variety of materials (sheet, plate).The heater is fastened to the wall with the frame and the anchor system.It is the most popular method of insulation of town houses, as options the external cladding home a lot - ground and vinyl siding, ceramic panels.

Ventilated facade panel improves insulation quality of construction and building materials extends operating time

significant advantage of this technology is that, if necessary, can be fairly easy to get to the insulation layer, it is enough to remove several panels.Plus, you can use this method for buildings in which insulation was not planned at all.Ventilated facades are installed on brick walls, and wooden and concrete surfaces.

Basic requirements for thermal insulation materials ↑

works on warming homes should be comprehensive, the 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 - foam, and as the house of wood, it is more suitable mineral wool.Of course, this is not the ultimate truth, since each heater has its own strengths and weaknesses.

main characteristics that need to be considered when choosing the material, such:

  • breathability;
  • vapor permeability;
  • hygroscopic - the absorption of vapor from the air;
  • thermal conductivity;
  • fire resistance and fire resistance;
  • biostability;
  • chemical resistance;
  • hydraulic conductivity;
  • thermal.

For example, polystyrene has almost ideal characteristics, but still there is one drawback - the high flammability and recovering 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 create a rational thermal insulation design, then we can avoid such unwanted 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 from the outside and make it warm and beautiful?It is best to insulate the house from the wood mineral wool: it's light, well-kept warm and not at all expensive.It is soft and flexible material that is easy to style, also is not affected by thermal deformation and do not arise cold bridges.After warming the house facing possible material, 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 required for buildings of wood ↑

Insulation of wooden houses begins with a vapor barrier.It can be used as an aluminum foil, plastic wrap or a special film-paroizolyator.The main objective of this process - ensuring ventilation of the facade.In case of round logs house, this problem disappears, and if the surface is smooth, then stuffed uprights, and on them is mounted a vapor barrier.

Important: obligatory between the base strips above and below need to make holes for ventilation - 20 cm in diameter.

Places fixture vapor barrier material (staples, nails) are sealed with tape to prevent water back have been reported.

frame - the foundation for insulation systems ↑

of the boards - the thickness of 40-50 mm and a width of 100 mm, the frame is performed for insulation.Boards are punched on a wall 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 ↑

boards mineral wool boards are installed between the frame without leaving cracks and gaps.Mineral wool is placed in two layers (50 mm each) as follows: the joints of the first layer should be combined with the second middle of the plate.Mineral wool - a semi-rigid and elastic plate, so they are kept between the boards without additional fastening, that is, they do not slip.

Placement waterproofing layer ↑

waterproofing heat insulating layer is covered with a film, which should free flowing steam and retain water well.This film is nailed or stapled to the frame.

Important: it is desirable to leave the overlap at the joints of 5-10 cm, and the adhesive tape sealing the joints.

frame - the second layer ↑

on board with the insulating layer (on top of the waterproofing) stuffed rail - width 50 mm, thickness 30 mm.This is done in order to ensure free circulation of air between the insulation and paneling.This means that condensation and moisture, which falls on the waterproof layer will be dried.At the bottom of the space with the closed metal grid (required thick), the necessary measure will protect the wall from penetration of insects and rodents.

siding - finish ↑

At this stage of warming the house of wood is completed, the final cladding mostly performs a decorative function.That is why the choice of cladding material - a matter of taste and personal preference.

This should also take into account the increased thickness of the walls - about 20-25 cm, respectively deepened the existing doors and windows.For this reason it is necessary to consider the protection of a warming system from windows.

Video: opinion and advice of the builders of wooden house warming ↑

There are many conflicting opinions about whether or not to insulate the house from wood.In the video you will find answers to many questions of professionals.

Proper execution of all phases of work on warming provides a good temperature in the house - warm in winter, and in summer - cool.And by verifying 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.
