Types of heaters for a wooden house

Houses made of lumber demand duebenefits that they currently pose. Natural atmosphere in a wooden house, gives comfort and warm positive energy. But this does not mean that a house does not need insulation.

Mineral wool - the best insulation

Mineral wool - the best insulation

The best option for insulation of wooden house- mineral wool. It is believed that the highest-quality insulating materials - URSA, ROCKWOOL and ISOVER. Insulators listed brands have excellent insulating properties, low thermal conductivity and a record low hygroscopic. The raw material in this case is rugged basalt rock.

Why are mineral wool?

Mineral materials are recognized as one of thebest helpers for the protection of wooden houses from adverse weather conditions. Why? Mineral wool - non-combustible material, which is indifferent to the effects of mold, fungi and insects, has no toxic substances in the composition and promotes the conclusion of vapors into the environment.

What experts recommend

Professionals engaged in the construction houses of timber, and according to their thermal insulation, it is advised to pay attention to the following materials:

  1. URSA fibrous materialsmade from mineral dolomite and quartz. Coefficient of thermal conductivity equal to 0.032 W / mK. Their main advantage - the flexibility and increased elasticity, greatly simplifying the installation process.
  2. Material Ursa FRONT destined for insulating walls. It is a rigid plateglass fibers treated with a water repellent solution additionally. Ursa FRONT plastered with black glass-fiber high-density, eliminating the need for installation of the wind protection film coatings.
  3. ROCKWOOL mineral wool with a specialhydrophobic impregnation, which consists of basalt rock. The thicker the insulation the mineral fibers are arranged in a chaotic manner, which leads to high strength. A minimum quantity of binder contributes to maintaining the original shape in a heater for a long time. The market offers different options: plates, mats, rolls of different thickness and softness. Thermal conductivity ranges from 0.033 to 0.043 W / mK.
  4. ISOVER mineral wool, fiberglass, and based onIt has remarkable characteristics teplosberezheniya, structural stability and durability. The upper surface is covered with glass plates, and hence the need to install diffuse membrane disappears. In the case of a two-layer insulation of this type of heater is used as the top.

Insulated from the inside or the outside?

The question is, perhaps, care of everyone whoreflects on the problem of how to insulate wooden house. Warming increases the thermal insulation on the outside wall, without reducing the living space. The walls are sheathed in this case film, which is placed on top of a heat insulator. The best laid staggered to the joints of the layers do not coincide.

Thermal insulation inside the undertaking, if planneddrywall finishing. The frame can be made of metal profiles, which are laid under the sealing layer. After laying and fixing screws mineral wool should close its film. Only then proceed to installation of gypsum boards.

From the correct location depends on insulationsuccess of the campaign, entitled "how to insulate the house from a bar." If dense materials insulation, do not let the condensation, placed inside the premises and porous - outside, create excellent conditions for keeping warm is not difficult.

It is important!
The air gap between the insulation and the wall is needed to protect the wooden house from the ravages of fungi and mold.

Stoning houses of timber can be ceramic or concrete blocks, stone, brick. Insulation while sandwiched between facing and a wall.

External insulation technology

insulation construction consists of the following components: paroizolyator, frame, insulator, a second carcass ply paneling.

insulation components

The circuit arrangement of functional layers of external thermal insulation


Insulation of the house from a bar begins with the devicevapor barrier. It can be plastic film, aluminum foil or roofing felt. Paroizolyatora task - to ensure the ventilation of the facade under the film coating. If the house is built of round logs, such a problem is not necessary, but if the walls have a smooth surface, it is necessary to fill them narrow vertical slats 2.5 cm thickness in increments of 1 meter. Then, the entire surface of a vapor barrier is placed. Top and bottom rails are made between holes 20 mm in diameter. Ventilated paroizolyatorom layer between the wall and does not give moisture to accumulate under the film, and thus help to avoid wooden walls rot lesions.

It is important!
Places paroizolyatora fasteners (nails or staples) are sealed with tape.

frame device

The frame is made of planks 100 mm wide and 50 mm thick. Boards stuffed on the wall vertically, on edge, so that the distance between them was less than 2 cm width insulation.
Thin board use is not: they will be useful for fixing the lining.

heat insulation

mineral wool slabs are placed between the frame boards. Make sure that there are no gaps between them. Two 50 mm mineral wool thickness of each layer must be laid so that the joints of the first layer is communicated with the means of the second plate.

This need to know!
Plates of mineral wool is quite tough and resilient, have a density of 80-120 kg / m3, which allows them to be retained, not sliding, no additional fastening between boards.


On top of a heat insulator to be laidwaterproofing material. The film should be free flowing steam, but retain water. Waterproofing is applied on top of a heat insulator and nailed to the frame with nails or staples. To film the docking place of 10 cm, self-adhesive sealing joints.

The second carcass ply

On the carcass stuffed with insulation boardRacks 3 cm thick and 50 mm wide. It is necessary for the free circulation of air between the outer shell and paroizolyatorom and condensation drying. Below the resulting space is needed to close a thick metal mesh for protection against insects and rodents.


Cladding - plastic or wood, performsmainly decorative function. What material is better to use - a matter of style, inherent in your home as a whole. Note that the increase in wall thickness at warming by 10-20 cm deepen the doors and windows, so you need to think about how to insulate the system will be shut down by the window openings - siding, trims and new sills.

Handwritten warming home from a bar

In general, it is desirable to solve the problem of warming at the stage of designing the house - it will help to think carefully about all the progress and save a considerable amount of money. Consider the main stage of warming.

Eliminate heat loss through the foundation

Often, carrying out insulation of a wooden house,insulation of the foundation are not taken into account. But if this is not done, the floors in the house are very cold. Structural insulated prior to construction of floors and walls.

Insulation of basement

Insulation of basement

The easiest way - to the level of filling of the base of the future insulated floor ground. The method is applied to the charging wall.
Not less popular keramzit - inexpensive insulating material, for which you want to build the formwork.

This need to know!
To manufacture the formwork can be second-rate or slate boards. The slots between the floor and closed expanded clay mineral wool.

Styrofoam - is also a reliable way of warming. Plates are glued on top of the waterproofing layer of mastic. The thickness of the plates depends on the depth of the base, the soil properties, common climatic conditions, the presence of the basement. Expanded polystyrene is necessary to bring to the floor level of the first floor.

Warm floor at any season

floor Warming

floor Warming

Floor insulation technology will depend on thestructure. If the earthen floor, it is suitable as a heat insulation layer of foam or granshlaka covered with screed. If the floor - a design that is installed on poles, it is possible the installation log from the bottom hem of their draft board, on which is placed a layer of heat insulation similar height lag.

This may be a layer of polyurethane or mineral wool,laid without gaps. Thickness - not less than 100 mm. Over lag and heat insulation is applied waterproofing film, and then - the boards of the floor. Between floors floors are insulated in the same way.

Walls will not miss the cold

On the wall insulation was told in detail in analyzing the structure of the device insulation. Recall that the layers must be such (inner skin out):

wall insulation

wall insulation

  • paroizolyator (from getting moist air protection);
  • insulator (insulation thickness of 100 mm);
  • waterproofing (film which passes steam but retains moisture).

How to insulate the ceiling

Thermal insulation of the ceiling is no different fromfloor insulation, but instead used the lag beams spanning the house. Between them is placed a thermal insulator, surrounded by steam from the bottom and top - waterproofing. The construction is sheathed with boards, which will be attached drywall - the basis of the floor of the second floor.

It should know!
If the device is not intended to attic, the sheathing boards are not necessarily.

Do not forget about the attic

It is important to remember the sequencestacking layers. Part of the insulation must match the insulation of the roof, and the walls and ceiling of the attic should be insulated according to the principle described above. Only one layer "sandwich" coincide with the previously described circuitry will not. Waterproofing must be filed by the entire surface of the roof, which means that the horizontal and vertical surfaces (walls and ceiling) is further laid waterproofing is not required.

Be sure to insulate the roof

That's where, certainly not worth saving. Roof "runs" in particularly difficult circumstances, is affected by rainfall, changes in temperature, physical stress from the wind, so choosing the material, first think about the quality, and then - the cost.
Warming of the wooden house roof It depends on the intended useattic. The attic is not habitable place? Then, the inside can not insulate the roof, think only insulation attic floors. But if you plan on living attic, the insulation of the roof becomes a very necessary.

Thermal insulation of roofs

Thermal insulation of roofs

Before you begin, perform an audit of the roof parts for moisture, rot and damage. The wooden structure is treated with antiseptic, damaged parts replaced.

If the wooden house is in operation andIt has a flat roof, insulation possible from both inside and outside. While it may be that there will be quite enough for comfortable stay of the outer insulation.
To work need basaltic mineral wool -durable material, which not only protects against mechanical stress, but also has high fireproof performance, which is very important for wooden houses. Insulation of flat roofs in the following order:

  • deck vapor barrier of the film;
  • laying insulation layer (basaltic mineral wool);
  • flooring coil coating of synthetic material or roofing felt (gidrobarer);
  • bulk material.

Owners of cottages and country houses, choosingperfect thermal insulation, it is necessary to get acquainted with an interesting complex way to improve heat insulating qualities of the wooden house with the help of mounting facade thermal panels and change window size:

Now that you know how to properly insulate wooden house, which means that winter will be cold to you are not terrible: in the house from a bar is cozy and very warm.
