Wooden houses are still favorites to the private housing market, because they have the best climate, easy to breathe and the heat does not emit any harmful substances.But the level of heat saving can not be achieved to the maximum by a single tree, because the cold will penetrate from the street in the same way that clean air, iethrough the pores of the material.In addition, the tree is short-lived, and eventually its structure begins to break down, revealing more and more loopholes for penetrating cold.Therefore, the owners are trying to insulate the walls from rain by a finishing material and additionally insulate.It is often installed under the insulation of bar-shaped house siding, and some owners just sheathe frame.But the log and timber have their own characteristics insulation.Let us dwell on them in detail.


How is warminglog house from the outside?↑

House, delivered from whole tree, and looks very luxurious, so the installation of siding with insulation should not be held until the moment when the tree starts to crumble.If you are concerned about the purely economic aspect, it is estimated by experts: the cost of insulation and finishing in the wooden house of temporary residence (for example, the country), will be repaid only after 40 years, and in residential building - 15-20.But without warming you save the tree as healthy as possible, because no obstacles to ventilation.

House of whole logs
Do not try to warm log house from the outside until the moment when the tree starts to spoil, because you can not control a finished state timber

Another question, if the tree is old and in some places was crumbling, it is advisable to put the protection of thethe sun and the rain to stop the destructive process.But even in this case, do not rush to warming because teplozolyator whatever you choose, it would be bad for the preservation of wood.

Installing insulation
when installing insulation using basalt fiberglass insulation or use respirators to flying small particles do not fall into the airway

So, basalt and glass fiber insulation, the type of rock or mineral wool contains a lot of particles in suspension.It is easy to see when vstryahnesh plate.Then the space around you is filled with tiny particles flying.And as the air between the insulation and the log will go, all the suspension will inevitably penetrate into the wood structure, clogging pores, and some will reach the space, and you have to breathe it.In addition, the steam coming out of the house, will penetrate into the loose structure of the mineral wool.And if you do not provide adequate ventilation, wool loses its insulating properties.Moisture will settle on a tree, and the meaning of warming will come to naught.

Expanded polystyrene
Despite the high level of heat saving, polystyrene materials are contraindicated for wood, because they do not absorb moisture and provoke rotting walls

Do not use polystyrene for insulation materials, because, regardless of the quality of heat saving, they are poorly absorb moisture.Then, pairs of the rooms did not make its way through the insulation to get to the street and erode.And in the cold condensate will fall on the side of the beam, which is turned to the heater.Instead of a warm house after 10 years you will have a rotten log house, which will have to change most of the crowns.Question: do you need it?

Recommendations for external insulation of a log house ↑

But to protect the old building from the natural factors still stands.You can wall insulation from the inside, but on the streets simply sew up the log siding.When properly installed, you will extend the service life of wood about 10 years.You need to trim the vertical battens.It should be done only from a wooden beam.He's tough and easier to put on the uneven surface of the log.The thicker the crate, the better ventilated and less likelihood of the tree falling in the cold room.Therefore it is recommended to use a beam of 50-ku.In addition, it must be remembered that not stuffed siding from the roof before the house, and with a clearance from both sides of 5 cm. This is necessary to prevent moisture coming out of the tree could break out.

Warming angles log
For warming corners should be cut flush with the timber wall, covered with insulation and angle on both sides of the board to beat tight

only place recommended insulation - corners of the house.They freeze more than the basic wall by placing the timber.The best option for warming angles - mineral wool, because it is well ventilated.But it is better not to lay it under the siding, and a board or boards, creating something like a column, as did the old Russian masters.If you get a combined finishing with siding, then the frame will be protected from freezing.

what materials insulate better?↑

Unlike timbered buildings, insulation of walls of timber outside is justified not only an increase in heat-insulating properties of the structure.This allows you to save a useful area of ​​interior space.If you spend inside wall sheathing, then for every 10 will lose about a meter of usable area.

most suitable for wood technology is considered to be the creation of ventilated facades, because it allows the walls to breathe and, therefore, the microclimate in the house will not change.And siding - one of the best options for exterior finishing.

If we consider what and how warm the house from a bar, the least suitable materials are polystyrene (foam penoplex etc.).By themselves, these heaters work well on brick, block construction, but the wooden walls, regardless of the type of material, they are not suitable, as mentioned above.

Roll insulation
Round uncomfortable heaters mounted on the wall, and eventually under its own weight they begin to slump down

Selection of basalt and glass fiber insulation is huge and you can find both budget options, and quite expensive.They all work about the same due to a loose structure, excellent air retention.Just some of them (mineral wool) can saturate and lose moisture because of its properties, and the other (rock wool or glass) are deprived of this disadvantage.But if you create the right wall cake, the brand insulation is absolutely not important.Consider the installation of external insulation basalt wool for subsequent plating siding.

selection of insulation thickness ↑

is best insulation from the outside bar-shaped house not perform roll, and of plate heaters.They have higher stiffness, and eventually they do not opolzut down.The thickness of the wool selected taking into account the thickness of the timber.If the walls are made of 150-millimeter bar, then lay 100mm insulation.If the tree is thicker - 200 mm, it is sufficient to 50mm wool.

laying vapor barrier ↑

To protect the insulation from the vapor emerging from the interior, bar coat with special waterproof lining mastics or vapor barrier film.The second option (the film) is preferable because of its higher quality insulation.The film is fixed to the wall of the stapler, and the joints are glued shut.

Steam insulation film insulation protects against moisture penetration from the premises, and gives moisture from a tree comes out next layers of cake

Mounting batten ↑

on the bars recommended to put only the wooden frame.Metal profile will be colder in the winter the main wall, and between them there is a possibility of condensation.Crate stuffed with vertically plumb and level, because it will be installed siding.And any distortion will lead to distortions outdoor decoration.

Step bars are sized according to the width of the selected insulation so that it lay, without compressing or wrapping from the sides.Also take into account the distance between the holes for siding (find instructions on this in the installation instructions).Make sure all the frame advance promazhte antiseptic composition for preventing putrefaction.

Fixing heater ↑

When the crate is ready, begin warming the house from a bar: basaltic wool is fixed by means of special plug-umbrellas, trying not strongly pressed against the wall.A cheaper option fasteners - screws, length 10 cm. To their hat is not "drowned" in the insulation, mugs engravings of roofing or plywood and apply them before tightening the screw to the wool.The approximate square meter of insulation is 5 fixtures.

Stacking waterproofing ↑

Once the insulation is laid, it is necessary to protect it from moisture from the outside.To do this, crate lay superdiffuzionnaya membrane.This particular film, wherein the surface consists of pores that resemble a funnel.Wide side funnels trail to the heater, and a narrow neck - to the street.This ensures that the output pairs, accidentally fell into the heater, but do not let the water molecules from the siding.

Create ventilation gap ↑

the wooden slats frame is necessary to fill in the 5 cm thick, to between the siding and the film formed space.This will allow moisture trapped under the finish erode and settle membrane condensate.The movement of air created using the ventilation slots when installing siding, putting him not from the beginning of the roof to the bottom of the walls, not reaching them for a couple of centimeters.

Ventilation gap
order under the siding was not formed condensate, using strips, stuffed in the crate, create a ventilation gap

Installation of siding ↑

Reiki stuffed profiles, aligning the horizontal level, and start from the bottom assembly siding.

If the warming of the house is designed to meet installation technology, the wooden structure is not afraid of dampness, and the quality of preservation of heat you already feel the first winter.
