Features of warming a wooden house from the inside. How to insulate the walls in a wooden house from the inside with your own hands What kind of insulation is better for the walls of a wooden house from the inside

On the need for insulation wooden house the owners think about the low temperature in the rooms in winter, the appearance of dampness and mold on the walls, the high cost of heating.

Professional builders recommend insulating the walls of buildings from the outside, but there are situations when this is unacceptable. In such cases, thermal insulation is mounted indoors. Such work will be inexpensive. The article tells how to insulate walls in wooden house inside and outside.

Features of wall insulation in a wooden house

The wood used in construction has features that must be taken into account.

Wood is a vapor-permeable material; if used improperly, it becomes damp, becomes infected with a fungus, becomes covered with mold, and is destroyed by pests. Over time, the house settles in logs or timber cracks appear.

Old house made of logs, traces of aging of the outer walls are visible

A properly designed and installed insulation system reduces Negative influence to a minimum - otherwise there is no need to talk about the durability of the structure.

Comparison of thermal insulation methods

Insulation of wooden walls is possible from the inside and outside, each of the methods has advantages and disadvantages. Accept correct solution the information collected in the table will help about the method of installing thermal insulation.

Advantages	Flaws
Insulation inside the building
Preservation appearance Houses	The outer parts of the walls are not protected from adverse weather conditions
Can be combined with major or cosmetic repairs	The useful area of ​​​​rooms is reduced by the thickness of the insulating structure
Reconstruction does not depend on the time of year	The dew point moves inside the building, condensation may occur
No scaffolding required, one person can handle the job.	Loss of heat storage properties of wood
External thermal insulation
Usable area is saved	Insulation is protected by external decoration - the volume of construction work increases
The dew point from the wooden walls is shifted to the insulation layer - the walls do not collapse, there is no condensation in the rooms	Thermal insulation is carried out in the warm season
Insulation according to the ventilated facade method prevents the appearance of fungus and mold	Working at height will require strict adherence to safety measures. Can't work without helpers.

Before deciding on the method of carrying out the work, it is necessary to familiarize yourself with the options for insulating a wooden house from the inside or outside.

Material selection

To insulate the internal surfaces of the walls of the house and facades, many specialized heaters have been developed, each of which, however, requires proper use.

Insulation is supplied in the form of piece products or rolls.

When choosing, take into account:

• price;
• service life during which the performance characteristics and the geometric shape of the thermal insulation are maintained;
• fire and sanitary safety (availability of certificates);
• thermal conductivity characteristics;
• resistance to mechanical damage and climatic conditions.

Polystyrene has long been successfully used for thermal insulation of buildings. The mechanical properties and size of the sheets allow you to insulate the house with your own hands, and if you have the skill, you can do without helpers. In thermal insulation, two types of sheet material made from polystyrene are used. They differ in the way they are made.

Expanded polystyrene is called polystyrene foam. Represents plates white color. Balls are visible on the crack different sizes.

Expanded polystyrene (polystyrene)

Erudite polystyrene is most often light yellow or orange color, it is denser than foam.

Styrofoam

The material is well suited for warming a wooden house.

Advantages:

• light weight - 98% of the volume of the product is occupied by air;
• maintaining dimensional accuracy during long-term operation;
• low thermal conductivity;
• the possibility of mounting in different ways;
• self-extinguishing within 4 seconds - without maintaining combustion with an open fire, the foam goes out.

Foam Disadvantages:

• releases toxic substances when heated above 80 o C;

• easily damaged by mechanical action;
• quickly destroyed by exposure to sunlight;
• low vapor permeability, which must be taken into account, and facade ventilation should be provided.

When buying a heater, it should be borne in mind that a material with a density of 15 kg / m 3 cannot bear a mechanical load, therefore it cannot be plastered. Styrofoam with a density of 25 kg / m 3 can be plastered and used for street insulation. With a mass of insulation of 35 kg / m 3 and above, you can walk on it and most often the material is used for thermal insulation of floors. It is not economically feasible to use foam with such a density for walls.

Extruded polystyrene

Insulation on sale is found under the names Penoplex, Penoplex. Sheets have grooves (selections) along the edges, which allows them to be stacked with an overlap. This eliminates additional sealing of seams. The density of the material is higher than that of polystyrene, any extruded polystyrene can be plastered.

Jointing seams of extruded polystyrene

As with the use of foam plastic for insulating wooden houses, ventilated facades are arranged.

Mineral wool

Mineral wool is obtained by melting rocks. It is a fiber, between which there is a large amount of air, which provides thermal insulation properties. It is supplied to trade organizations in rolls or in the form of plates of standard sizes.

Material advantages:

• ease of installation;
• democratic price;
• does not support combustion;
• high rates of heat and sound insulation;
• environmental friendliness;
• high vapor permeability, commensurate with wood;

The main disadvantage is the ability of mineral wool to absorb water, while losing thermal insulation properties. Over time, the material shrinks and shrinks, and performance decreases.

To reduce the impact of water and moisture from the air, mineral wool is protected with a special waterproofing film.

glass wool

The structure of glass wool is similar to mineral wool, but inferior in performance and manufacturability. When exposed to water and moist air, it quickly loses its thermal insulation properties. Over several years, it becomes caked, which leads to a deterioration in performance. Installation of glass wool requires strict observance of safety precautions - the smallest particles penetrate the lungs during breathing and enter the eyes, causing irritation of the mucous membranes.

Ecowool

The material is obtained from waste paper and cardboard during the processing of waste paper, as well as waste from the textile industry. Additives prevent rotting, caking, combustibility of ecowool, insects and rodents consider the material unattractive for eating and nesting.

The process of applying ecowool

Laying ecowool on your own will not work - the material is sprayed, mixed with water by special installations.

Isoplaat

Wood fiber boards from sawdust coniferous trees produced without the use of chemical components.

Isoplatate sheets

The surface of the pressed sheets is treated with paraffin, which reduces the susceptibility to decay. The vapor permeability of the material is approximately equal to the characteristics of wood, which eliminates the accumulation of condensate between the wall and the insulation. It is applied to external and internal way of installation.

Foil insulation

The material is a foam substrate with a glued layer of aluminum foil. It is found on sale under the names Penofol, Isolon, Izodom, etc.

The material performs several functions:

• thermal insulation;
• soundproofing;
• waterproofing;
• wind protection.

Foil insulation

Products are resistant to chemical, thermal, biological effects and decay. Installation is reduced to fixing on a wooden surface with a stapler or with the help of nailed rails. When using foil materials, the insulation is nailed with a stapler, then the master has to decide how to sheathe the wall - drywall, distillation, plastic siding.

Warming process

Thermal insulation in log house It will be of high quality if you follow simple rules and a sequence of manipulations. Deviation from the algorithm and incorrect alternation of layers will make the results of labor meaningless.

There are two methods: frame and frameless. They are applicable for outdoor and indoor use.

Frameless way

Without pre-fabrication of the frame, it is possible to insulate with polystyrene foam and extruded polystyrene, basalt mineral wool, Isolate - that is, materials with structural rigidity. The foil material also does not imply a frame structure, although it can be used as one of the layers of the "pie".

Before installing the insulation, the walls are thoroughly cleaned of dust and dirt. Cut off or grind irregularities - the insulation should fit snugly against the base.

The simplest and fast way insulate the house - use Isolate plates. They are simply nailed with wide-head nails or screwed with self-tapping screws. Of the tools you will need a hacksaw for cutting sheets to size, a hammer or a screwdriver. The surface of the slab is plastered or trimmed with siding. Absence finishing will lead to the destruction of sheets under the influence of climatic factors.

Polystyrene sheets are attached to a wooden base with self-tapping screws, using wide plastic washers. Under the influence of ultraviolet, the foam quickly loses its mechanical properties, therefore, with external insulation, plastering work will be required within 20-30 days.

At the first stage, cement-based adhesives are used. Use a special mounting adhesive for polystyrene foam or glue for ceramic tiles.

The surface of the foam is covered with a thin 1-1.5 mm layer of glue, a fiberglass mesh is applied and sunk into the applied solution. The adhesive composition is re-applied and leveled. After drying, the base is treated with a primer and plastered using any composition compatible with cement. For example, plaster beetle. Surface can be painted facade paints.

House insulation basalt slabs

Similarly, insulation is carried out with basalt slabs.

Frame option

The frame method of installing insulation can be used for any materials, but it is mainly used for installing mineral wool. In the case of using foam, the grate can be used to fasten a finish on it, for example, siding.

Frame method of insulation

Installation sequence:

• surface cleaning;
• treatment of wooden walls with a bioprotective primer (antiseptic) and flame retardants (fire retardant impregnation);
• frame installation;
• installation of insulation between the crate;
• installation of a windproof membrane or plate;
• finishing installation.

The opinion is often expressed about the need to install a vapor barrier film between the beams of the walls and the insulation. Such a membrane can fulfill its purpose if the insulation is. For materials that are not vapor-permeable, such a layer is useless - moisture will accumulate at the “wood-insulation” border, accelerating the processes of decay.

For roll materials, the sequence may be different:

• surface preparation, chemical treatment;
• fixing brackets on the wall surface, on which the crate will be attached in the future;
• fixing the roll material with dish-shaped dowels.
• cutting into mineral wool holes through which the brackets protrude outward;
• Installation of a hydro-windproof membrane;
• Fastening finish coat to the frame.

By choosing the right heat-insulating material and following the above rules, you can qualitatively insulate a wooden house from a bar or boards. Comfort on winter evenings and lower energy bills will be a reward for hard work.

Wall insulation in a wooden house from the inside must be done, of course. After all, penetrating moisture contributes to the destruction of wood and not only does the structure become unusable, but as a result of this, the room will be damp.

How to insulate the walls in a wooden house from the inside, we will consider today. Also on the video in this article and the photo you can see the whole process of doing the work clearly.

Preparation for the main types of work

Insulation of the walls of a wooden house from the inside is done according to certain rules and in compliance with the desired sequence. This will depend on the quality of the work performed.

Before starting work, it is necessary to take measurements and calculate the material. And so, it is necessary to make calculations for the further choice of insulating material, taking into account, among other things, its properties (see Material for insulating walls inside: characteristics). Do not forget that during such work, membranes are used (steam insulating and waterproofing).

When calculating, set:

• Dew point output. This is one of the most important points in this type of work. Everything is explained very simply - how, in the end, it will be humid in the room, it directly depends on this, even in cases of high-quality material, and well-done work. The location of the membranes, and their properties (for different manufacturers they may differ), and of course the properties of the insulation (density, resistance to wetting) are taken into account.
• Calculation of the total area of ​​\u200b\u200bthe room, given that it will decrease. It may not turn out to be a comparison (an increase in slopes, and in the presence of a furnace, the safe distance will change, between the wall and the furnace, which is unacceptable for fire safety).

Important: The need for work to establish the dew point is not discussed. It is an inseparable part that ultimately provides the meaning of the whole work. You need to understand - the humidity of the room depends on the location of the dew point, and humidity is rotting, smell, in the end - premature decay.

Rules for performing insulation work

Do-it-yourself wall insulation of a wooden house from the inside is done if there is quality materials. Preference should be given to trusted brands, you can save a little on Chinese material, but you will significantly lose in performance.

What is needed to carry out the work

Insulation of wooden walls from the inside is done with heaters, there are quite a few of them. But you need to start from the structure itself and what you want to get in the end.

By definition, the insulation must meet the requirements:

1. Have low thermal conductivity;
2. Meet the requirements of fire safety;
3. Comply with environmental and chemical safety standards.

Attention: When choosing a heater, the density and heat transfer qualities are determined, taking into account the place of its application, weather and temperature characteristics, as well as the state of the building itself.

• The material used must not support combustion, emit hazardous compounds into the air, contain hazardous chemical elements. For interior work, the material is selected with great care, environmentally friendly and safe. This is important because - in a confined space, with constant contact, even a seemingly insignificant deviation from the norm can be dangerous, both for people and for pets.

Types and types of insulation materials

When deciding which method to use, you first need to decide what material will be used. This is interconnected, since the method and method directly depends on the type of material.

From possible ways used indoors - use:

Mineral wool	It happens in slabs and rolled, different density. In fact, there is almost no difference in application. Any of these materials assumes a closed type of application, that is, after laying, it must be closed ( finishing material in the form of plates, sheets, boards and slats). Such a heater does not burn, is not toxic, has a low thermal conductivity. But he is afraid of moisture, which means that it is necessary to use insulating membranes (insulating films).
Foam boards (expanded polystyrene)	It is not recommended to use it indoors, due to possible toxic release (hydrogen cyanide, styrenes, etc.). It is possible to use extruded polystyrene foam, but such material is also designed for laying with subsequent closing.
glass wool	Relatively inexpensive material, slightly higher thermal conductivity than mineral wool (a thicker layer is needed). There is a special option for interior work, and with the obligatory use of films for covering. When working, it is also necessary to observe safety measures (protect Airways against small particles, use protective equipment). After laying, it is necessary to close.
Isoplet	This material is environmentally friendly, it consists of flax fibers and wood shavings. Represents the pressed plates 12-25 mm thick. since this is a fairly rigid material, there is no need for a strong barrier (crate). Environmentally friendly, suitable for indoor applications. The disadvantage is a higher thermal conductivity, and the cost, at the same time, is higher than that of alternative materials.
polyurethane foam	It is applied using special equipment, it does not burn itself, but when high temperatures, toxic substances are released. It consists of 2 main components, when mixed, it transforms into foam, reminiscent of construction. It is sprayed with a small layer of 3-5 cm (the total area is slightly reduced), with the addition of "additives", it becomes water-repellent. The price of work increases significantly due to the use of a special installation. After spraying, it must be closed.

Now let's figure out how to insulate wooden walls from a practical point of view.

Sealing gaps, preparing the surface for insulation

From the moment the building was built, during its operation, the wood dries out, the house “shrinks”, the constant movement of materials. As a result, gaps and cracks are formed that must be repaired to stop heat loss.

• Joints between logs (or timber) - caulk. This is done available material, or the same as what was done before (tow, jute, sealant). As a result, heat loss must be stopped.

Everything about wall insulation from the inside of a wooden house: what material is better to use, the need for internal insulation, preparation and lathing of walls, how to properly insulate with mineral wool inside.

According to the masters, the external insulation of a wooden house is much more preferable than the internal one. This is related to the concept of dew point.

The formation of condensate on the walls inside the building under the insulation will go deep into them, while on the outside it will not go further than the hydro - or thermal insulation and will not reach the wood.

Wall insulation from the inside of a wooden house is possible only if other options are not acceptable for any reason.

The need for internal insulation

Before deciding on such interior finishes, you should consider what they can be fraught with:

1. Violation of the natural "breathing" of the walls, which will have to be restored by creating ventilation.
2. Changing the microclimate in the rooms due to high humidity.
3. Reducing the area of ​​each room.

If such good reasons are not a reason to change your mind, then you should look for the positive aspects of internal insulation and focus on them:

1. The ability to insulate the walls of a wooden house from the inside with your own hands at any time of the year, devoting as much time to this as possible.
2. A beautiful view of the facade, especially if it is made of logs, can be preserved in its original form.
3. Such work requires easier installation, which even a beginner can do.
4. The internal insulation of the walls of a wooden house is several times cheaper than the external one.

Modern materials and technologies make it possible to carry out construction and finishing works of any complexity and quite at a decent price. Before deciding on any action, you should be well acquainted with what materials the modern market offers and answer the question, what is the best way to insulate the walls of a wooden house inside.

Of course, the choice of material directly depends on the qualities that the building will require from it. If this frame house, then these will be some properties, and for a log house of thick logs - others.

Today, manufacturers of heaters offer the following types of materials:

All of the listed materials have a place to be in the modern construction market, but the choice is up to the consumer, to which of them he entrusts the safety and warmth of his home.

Wall preparation and lathing

As always, the insulation of walls in a wooden house from the inside (the video will tell about this) begins with preparing the walls for work:

1. Even the most best wood may form gaps at the joints during shrinkage. They should be sealed with sealant or in another way.
2. It is imperative that as a preventive measure it is necessary to carry out bio- and fire protection of the walls. Since thermal insulation is mounted for years, this will save it under any unforeseen circumstances.

   To protect the house from decay, without fail, when laying thermal insulation, you need to make an air gap between it and the wall. This does not apply to walls made of logs.

3. Caulking of walls is necessary if they are made of timber. Jute is well suited for this, as the cheapest and proven by many generations of builders material.

In no case should the preparation of the walls be ignored, as this may affect the durability of the thermal insulation and its quality.

Owners should think not only about how to insulate the walls of a wooden house inside, but also how to do it. It is imperative to make a crate. It is because of it that, first of all, the area of ​​\u200b\u200bthe room inside decreases, but it also gives the entire structure a shape and the necessary stability.

For the crate, a square bar with a section of 50 mm is used, and the step depends on the size of the insulation. It is important to install the bars so that the material fits tightly into the formed cells, if it is mineral wool, or they are exactly sized for expanded polystyrene boards.

Prior to installation, the bars must be treated with fire-fighting and antifungal agents. All structural elements are attached to the wall with screws.

After the crate is installed in each room, you can proceed directly to solving the issue of how to insulate the walls inside a wooden house.

Wall insulation from the inside of a wooden house

mineral wool

As a rule, mineral wool in a roll or in the form of a “mat” is used to insulate walls from the inside. To cope with the first, you will need work in 4 hands, while the second can be handled on your own.

Laying is carried out from the floor to the ceiling, observing a tight fit so that the seams are not visible. If there are any gaps, then they need to be repaired, and then proceed with laying the next layer of the “pie” - the vapor barrier layer. It is necessary rather to protect the mineral wool from exposure external environment rooms than walls.

The vapor barrier should be overlapped with a stapler so that there are no seams, and if there are any, then they must immediately be covered with adhesive tape.

After the work done, it is necessary to mount another crate, but opposite to the first. It is on it that the finish coating will be attached.

Styrofoam

This material can also be attached to the crate, but there is an easier way that does not take up much living space. The prepared and processed wall must be smeared with a layer of glue and put foam sheets on it in dense rows.

After the adhesive base is completely dry, the plates can be fixed with nails, cover the gaps and proceed with the finishing.

In conclusion, the following conclusions can be drawn:

1. Internal insulation is not desirable, but is acceptable if necessary.
2. There are materials suitable for these works.
3. Before proceeding with the insulation, you need to properly prepare the walls.

If there is not enough knowledge on the composition of the material and the correctness of its installation, you should consult with a specialist so that after years you will not regret the wasted money. Even such a simple, at first glance, work as caulking the walls requires skills and attention, and without creating ventilation, the “life” of the building can be significantly reduced. All this should be considered before the start of warming. internal walls wooden house.

Insulation of a wooden house from the inside using, among other things, is a necessary set of measures in order to increase the level of comfort when living in it.

When insulating the roof, ceiling, attic and floor, in most cases one technology is used. In this case, thermal insulation can be provided with mineral wool or foam.

1 Insulation of the walls of a country house from the inside

Before you start warming the walls in a wooden house with your own hands, you should thoroughly clean all surfaces from dust and dirt. If the house is made using timber, then thermal insulation can be provided with foam or mineral wool.

Before that wooden surfaces country house, including the surface of the ceiling, the ribs of the timber, the walls of the attic, and the inner surface of the roof, must be subjected to detailed treatment with a special insect repellent emulsion. All insulation work of a country wooden house, brought inside with your own hands, consists of:

• Caulking of cracks in the walls of the attic, the surface of the ceiling and inside the roof, as with;
• Creation of a vapor barrier for the floor using timber;
• Lathing installation;
• Laying insulation and ensuring the sealing of the roof of a country house;
• Creation of a ventilation system between the walls of the attic;
• Internal finishing works for the preparation of beams, ceilings and roofs.

In addition, at internal insulation the walls of a wooden country house made of timber with your own hands, you need to carefully monitor the condition of the electrical wiring.

For example, if the walls of a country house are made using timber, and the technology involves wiring surface wiring on the walls of the attic, then it does not have to be separated from the wall surface.

To do this, it is enough to hide the wiring in special decorative casings. Inside them, the wiring will be safe.

After the walls are cleaned and the thermal insulation is prepared, it is necessary to caulk all the existing cracks.

Caulking is carried out not only on the surface of the walls of the attic, but also in the inner surface of the roof. It is known that in the case when a house is built using a beam, the floor, attic walls and the inner surface of the roof are re-caulked only a year after the building is put into operation. .

In the case when people immediately began to live in a house with a timber, drying the ceiling, floor and inner surface of the roof will be much slower.

Based on this, it makes sense to carry out the second caulking in at least 2-3 years. By the way, for caulking the walls of a house made of timber with your own hands, in most cases, jute fiber is used.

After that, you should proceed to the insulation of the walls with foam or minata. Inner surface the ceiling and roof (in the attic) can also be insulated with foam plastic with your own hands.

2 Creating a vapor barrier

When insulating a wooden house with your own hands, it is extremely important point is the creation of a vapor barrier inside the walls of the attic.

This is because the space inside wooden base The attic wall consists of those bars that are locked between two heat insulators.

In this case, the humidity level in the rooms will certainly increase, which will lead to the appearance of a "thermos effect" in the space from the ceiling to the roof.

This will lead to the fact that the entire structure will stop "breathing". Excess moisture is eliminated by ventilation.

The main thing is not to allow the tree to become damp, while slow decay of the entire structure may begin. To avoid this, before starting the installation of a heat insulator, the entire surface of the wall to be insulated must be equipped with a vapor-water-proofing film.

When implementing installation work as in the case of creation related to the crate on load-bearing walls made using a bar, an additional metal profile is installed.

This is especially true when finishing and vapor barrier will be made with the participation of moisture-resistant drywall.

After that, a strip of mineral wool is located inside, in the space between the bars. And its layers will join the base of the wall with the help of anchors equipped with enlarged round caps. A second layer of vapor barrier film is laid on top of the insulation.

2.1 Creation of ventilation insulation of walls with foam plastic

A well-designed ventilation system should not have direct outdoor hoods in its communications.

Most suitable option- this is a combination of a system into one circuit through the communications of the ceiling and the attic.

This is done through ventilation ducts. Any axial fan with a low or medium power rating can be used as a supercharger.

When activating the ventilation system using winter time of the year for half an hour, you can influence the parameter of optimal air humidity.

Inside, the second layer of vapor barrier film is attached to the beams using staples of a construction stapler. After the bar is installed, it should be sheathed with a clapboard made of wood.

This will give the room a certain degree of aesthetic appeal and insulate its contour. In addition, it is desirable to finish the room inside with a vertically located planken.

In addition, the walls can be insulated from the inside with foam. It makes sense to start installation work with the selection suitable sizes sheets. They can be much thinner than with the behavior of external insulation work. Styrofoam is different:

• Simplicity and ease of installation;
• Low degree of thermal conductivity;
• High soundproofing characteristics;
• Long operational period.

When the internal walls of a wooden house are insulated with such material as penofol, convection and significant heat loss through the cracks will stop forever due to the fact that the caulking was produced poorly.

If the timber will have a relatively small thickness, then frost formation will not be observed in the corners and on the walls of the house in the winter season. When using polystyrene foam, the space of the room from floor to ceiling will warm up quickly enough.

2.2 Floor insulation

In addition to a set of obvious advantages, in the event that the wooden floor is insulated, the level of heat loss in the house will significantly (up to 20 percent) decrease. That's an example.

The most simple and sufficient effective method floor insulation is associated with the use of mineral wool as a heater.

The technology of insulation using mineral wool is quite simple and not expensive. Particularly relevant is the insulation of the floor with mineral wool in the case when it is mounted directly on the surface of the soil.

The choice of a type of heat insulator directly correlates with the features of the arrangement of the floor. So, if the installed insulation will not be subjected to regular technical loads, it is recommended to opt for a mineral wool with a density of 50 kg / m3.

If the load on the slabs is carried out with a periodic frequency, then the limiting density of the min-slab can reach 160 kg / m3.

In this case, the material is not mounted with fasteners, but is laid freely. Another option for warming a wooden floor is associated with the use of foam.

First you will need to dismantle the old coating. After that, you need to take care of installing a waterproofing layer.

For this purpose, polyethylene can be used. After that, you can start applying penoplex, which is characterized by low hygroscopicity.

In some cases, it is possible to insulate the floor of a wooden house using foam boards. You can use for this one of its varieties - expanded polystyrene, which is a fairly relevant heat-insulating material.

The whole process begins with the fact that a gravel cushion is formed on the ground, the thickness of which can reach 30-40 centimeters. This layer is thoroughly compacted, after which cleaned sand is poured on top with a layer of 10 centimeters.

2.3 Ceiling insulation

At present, despite the enormous abundance insulation materials in the modern construction market, a large number of homeowners prefer to insulate the floors in a wooden house the old fashioned way - with sawdust.

This method is primarily characterized by its high environmental friendliness parameter and relative cheapness.

However, the work associated with the presented material is quite troublesome. In addition, this method requires some preliminary preparation.

For example, sawdust must be carefully treated with an antiseptic before starting insulation in order to avoid the appearance of mold.

Sawdust should also be sprayed with a flame retardant in order to improve their fire-resistant qualities, as with. Before backfilling, this material must undergo a long drying.

And in order to prevent rodents from climbing into the insulation, it must be diluted with fluffy lime. This mixture must be poured into the voids formed.

Moreover, its layer can reach a height of 20 centimeters. For floor insulation, modern materials such as mineral wool, polyplex, expanded clay and foil-type polyethylene foam can be used.

It is not bad to use such alternative heaters as glassine. It can cover foam boards.

Insulation of a wooden house from the inside - layout of materials

When choosing one or another material, special attention is paid to the financial capabilities of the owner of a wooden house. Based on this, you should decide on the price segment in which this or that heater is located.

2.4 How to insulate a wooden house from a bar? (video)

To insulate a house in which there is no interior decoration much easier than doing it in an already fully equipped and ennobled house. Do not rush into any internal works until every room in the house is properly insulated. Thanks to modern materials, you can do it yourself. Any room will be cozy and comfortable if you approach the matter competently and carefully read the technology for insulating the ceiling, walls and floor.

Insulation of the ceiling of a wooden house

As a rule, ceiling insulation is not treated responsibly. Many people think that it is not necessary to insulate it, but this is far from the case. The air that people try so hard to warm in winter rises up and goes through the ceiling to the street. Making a serious mistake - leaving the ceiling not insulated, many themselves, without knowing it, lose half of the heat, they waste cash on warmth fading into the unknown.

Ceiling insulation material:

• Mineral wool. This material is not expensive, but reliable and easy to install. He is one of the few heaters with whom you can work on your own without calling for help from other workers and, most importantly, do not pay them money.
• Glassine. Used as a waterproofing material is used.

For frame structures and sheathing you will need:

• Cutting board.
• Nails, glue, polyurethane foam.
• Drywall.

Ceiling insulation tools:

• Hammer.
• Hacksaw.
• Screwdriver.
• Electric jigsaw.
• Tile adhesive.

Stages of ceiling insulation:

1. From edged boards we make a frame, you need to be prepared for the fact that this will reduce the height of the room. The distance between the boards of the frame should be no more than 1 meter.
2. Between the boards of the frame it is necessary glue glassine without leaving empty seats In order for the material to hold well, it needs to be slightly smeared with tile adhesive.
3. Over glassine we lay the insulation- mineral wool. Do not leave holes between the insulation. If the material does not hold, use tile adhesive in small quantities.
4. The last step is plasterboard ceiling lining. Using a screwdriver, we fasten sheets of drywall to a wooden frame.

It is necessary to insulate the ceiling from the inside in the warm season and not earlier than 1 year after the construction of the house. Only in this case, the insulation will pass correctly and last for many years.

If it is decided to insulate the walls of a wooden house from the inside, you need to know what, in this case, the walls can condensation will form. The northern places of the globe are especially subjected to this, where it is very cold in winter and warm in the rooms. This happens due to the effect of a temperature difference, during which the dew point moves into the insulation layers. This situation can be corrected film, which is used together with a heater, or to carry out good ventilation.

Required inventory

• Jigsaw, impact drill, screwdriver, mallet, tape measure, level, plumb lines, chisel, screwdriver, hammer.
• Wooden bars.
• Felt, foam or tow.
• Material for wall insulation, for example, glass wool.
• Drywall.
• Putty.

Modern materials for thermal insulation of walls

• Ecowool- this material perfectly fills all the cracks and voids present in the walls, at the same time preventing blowing through the walls. It does not allow moisture to penetrate inside, thus preventing the occurrence of fungal infections. One of the few breathable materials.
• glass wool- choosing this material in the insulation, you should take care of the thermal insulation in the room, as glass wool allows a small amount of moisture to pass through, as a result, thermal insulation properties deteriorate.
• Styrofoam- one of the most common materials for wall insulation in wooden houses. First of all beckons with its cheapness. Also positive qualities are elasticity and lightness. The material has heat and sound insulating qualities.

wall insulation technology

All cracks in the wall must be sealed. foam, linen felt or tow. You can choose any material that is more convenient to work with. We make a crate from wooden beam. We place a place for installing the extreme elements of the crate. Particular attention should be paid to this it depends on the first bars how smoothly the next ones will be attached, so use a level and plumb lines to verify.

If the definition of the first beam is completed, it should be fixed with screws and dowels. Should be fixed every 25-30 cm. Then we measure 1 meter from the first beam and fasten the second one in the same way parallel to the first, etc. until the full perimeter of the crate is formed on the entire wall. If you meet on the way window openings, they should be beaten with bars in a circle.

Each beam must be treated with antiseptics to prevent rot and fungus. The crate is ready. Between the bars should be laid insulation. No need to use glue, the material will already hold tightly between the crate and the wall.

Making insulation. Used for insulation film or polyethylene, it is superimposed on top of the insulation with small allowances at the edges.

The last step is finishing. We cover the walls with plasterboard, we fasten it to the crate of the bars, it is important that the plates fit snugly against each other. If cracks appear, they should be filled.

Insulation of the floor of a wooden house

Tools and materials for work:

• Hammer, drill, saw, electric jigsaw.
• Nails, tape measure, pencil, knife.
• Level, planer.
• Mineral wool.

The concrete floor in a private wooden house necessarily requires insulation. It is worth noting that the process of floor insulation is not easy, but you can do it yourself by spending your personal time and effort. Consider the method - "raised floor", it will raise the floor at least 6 cm, but makes the room much warmer.

Mineral wool for floor insulation

Mineral wool has been inexpensive but effective material.

Advantages mineral wool:

• This material sound and heat insulating.
• Excellent features and reviews.
• Duration service life.
• Low density.
• Does not deform practically under no circumstances.
• The price is always available for any citizen.
• Available in 2 types: flexible mats or rigid boards.

The only competitor to mineral wool is expanded polystyrene, which boasts of its practicality and ease of installation.

Insulation of a wooden house should be carried out completely, it is necessary to insulate ceiling, walls and floor. If the ceiling is insulated and there is no wall, warm air will still leave the room through microcracks and then all work will be in vain. On modern market you can buy a lot of thermal insulation coatings and tools for home insulation. If you approach the matter competently, even an old wooden house will be cozy and warm in the coldest winters.
