And although wooden buildings look very beautiful and rich, they also need to be insulated from the outside. This will not only allow you to create reliable protection from moisture, but also from cold. Installation work are not particularly complicated, but if you do not have proper experience in this matter, then it is better to seek help from a specialist.
A wide selection of thermal insulation materials allows every owner wooden house pick yours perfect option taking into account cost and performance.
This material can be cut even with a regular knife. Since the slabs are light in weight, they are very easy to transport even in a passenger car.
Stone wool
When laying stone wool it must be mounted in the space between the sheathing posts, and then laid vapor barrier material from the inside and a layer of waterproofing from the outside. But how to insulate a wooden house from the outside with mineral wool under siding will help you understand this
This material is characterized by its environmental friendliness. Cellulose fibers were used in its production. Produced in compressed packaging. The process of insulation with the material in question can occur in several ways:
This material is considered one of the most inexpensive. It does not absorb moisture, so when installing it, care must be taken to install a moisture-proof membrane. When working with polystyrene foam, maximum care is required, because it can crumble and break.
Styrofoam
It is sold in the form of two-component substances. When applied, they foam under the influence of air. The principle of applying this heat insulator is similar to polyurethane foam. With its help, all voids in the wall are filled. Excess material is cut off.
Thus, it is possible to obtain a monolithic layer of insulation that will prevent heat from escaping from the house. Polyurethane foam is also characterized by water-repellent properties. It’s worth paying attention to what’s happening
This category of thermal insulation materials includes slabs made of straw, clay, and sawdust. They are distinguished by their environmental safety and low cost. Their main disadvantage remains the complexity of manufacturing. Flax fiber should also be classified as a natural insulation material.
Sawdust for insulation
The material has excellent antiseptic properties and prevents the formation of fungus and mold. It is easy to cut, install and does not cause allergies. But how this happens and how to do it correctly, the information at the link will help you understand and figure it out.
The process of installing insulation varies depending on which material option was chosen. If the heat insulator is presented in the form of mats, then installation requires the following steps:

If a wooden house has a brick cladding, then it can be insulated from the outside using various thermal insulation materials. When choosing suitable option it is necessary to focus on thermal engineering calculations, thanks to which you can understand the effectiveness of a particular heat insulator, as well as its useful thickness.
It is also worth paying attention to what materials are the best.
This material is most often used when insulating a wooden house with brick cladding. Its main advantage remains low price and excellent thermal insulation qualities. Before installing foam plastic, a brick wall should be cleaned and leveled. But what is the technology for insulating the facade with polystyrene foam, and how difficult it is to do it, is indicated
Foam plastic for insulation
Fastening is carried out using special bolts. They are screwed through the heat insulator into the masonry. Facade plaster is applied on top of the foam.

This insulation material has been in wide demand for many decades. Mineral wool has excellent sound and heat insulation properties, provides decent ventilation and has low flammability. On to the cons mineral wool It is worth including a decrease in thermal insulation properties over time.
Mineral wool for insulation brick house outside
This modern material allows you to achieve maximum heat savings inside the house. Thermal insulation is produced in the form of rolls or solution. To insulate a wooden house, you must use liquid composition. It is pumped by special pumps into the space between the wall and the brick. Using roll material a number of difficulties arise, so it is not used so often.
Application of isolon
Isolon is characterized by excellent impact strength, which has a positive effect on its service life. The only disadvantage of the heat insulator is that it has an unattractive appearance. So you will have to take care of additional finishing.

I want to insulate a log house lined with brick.
I want to insulate my house. The house is log and covered with brick.
First you need to organize general ideas and myths about wall materials. New materials don’t inspire confidence in you, but old ones - bricks, logs, with which you have already flown in the heat - do they inspire confidence?
Most people think that the warmest are logs and bricks. And you are going to insulate a log + brick, that is, you are breaking this myth.
If a house breathes, this means that it does not maintain internal temperature well - in winter it independently exhales heat and inhales frost, and in summer it is the other way around. The normal option is when the owner regulates breathing. With an area of up to 200 sq. m there are enough vents for this, and in big houses do ventilation.
There is a wonderful PPU material - polyurethane foam, yes, not the cheapest, but this is compensated by minimal labor costs. Drill holes either from the side of the log or from the side of the brick and use cylinders to fill the former ventilation gap. This is a wonderful insulation material; in addition, as it expands, it will hermetically seal all the cracks and block the access of moist air from the street, that is, it will protect the wood from rotting and all kinds of bugs and spiders. It will bind logs and bricks into a monolith - that is, it will significantly increase the strength of the wall itself. And you can do all this alone, without particularly straining, in 2 - 3 days.
September 4, 2016If you are looking for ways to insulate brick house outside, then you are on the right track, since this method is much better than internal insulation. However, if you suddenly want to do it on both sides, then this option will be even better, or rather, the best. I want to tell you about the difference in insulation, as well as its execution technique, and also show a video in this article.
There are three main methods of wall insulation for brick walls: insulation can be installed on the outside, inside and in the middle (well masonry).
What the insulation of internal walls portends for us:
External wall insulation will be most optimal:
How good is this method:
In the photo - mineral wool
The production of mineral wool is carried out in accordance with GOST 31913-2011 and EN ISO 9229:2007 and, in fact, this is the insulation of a brick house from the outside modern methods, that is, accessible and effective. But here you should be selective, since there are three types of minerals that are used to make such products. It is divided into:
So, all this is made from melts of materials of the same name, which behave differently under certain conditions.
Thus, slag wool, made from blast furnace slag melts, contains particles of iron that are susceptible to corrosion from moisture (dew point) and the material sags, losing its insulating properties. Therefore, the instructions do not recommend the use of slag wool in such cases..
Those who have worked with glass wool know how harmful it is to health (dust particles of glass) and how it irritates the skin - you only need to work in a respirator and clothing that covers all parts of the body as much as possible.
It is quite natural that the best option here would be basalt wool, besides, to work with it, only gloves are enough, although most installers generally work with bare hands.
As you may have noticed, in the photo above there is foil and plain cotton wool. The foil layer simultaneously serves as a waterproofing and heat reflector (reflects infrared radiation), which significantly increases the insulation power, however, at the same time its cost also increases.
Polystyrene foam is a common insulation material, and it has slightly greater power than mineral wool. In addition, it is much more convenient to mount it on walls and.
This material is produced in the form of square 1000x1000 mm panels with thicknesses of 20 mm, 30 mm, 40 mm, 50 mm and 100 mm. But for domestic purposes, two types of densities are used - 15 kg/m3 and 25 kg/m3, although 15-th sheets, when cut, greatly crumble into granules, which cannot be said about 25-th panels.
Very similar in appearance and in structure to extruded polystyrene foam. But this material has a density of 35 kg/cm3 and 45 kg/cm3 (the latter is even used for insulating runways).
Panels extruded polystyrene foam for such purposes, 1200x600 mm is usually chosen, and its thickness is from 10 mm to 100 mm with all values divisible by 10. Of course, the thermal insulation properties are better here, but the cost is naturally much higher.
There is also such insulation as penoizol or urea-formaldehyde foam. This is, in fact, the same polystyrene foam, only in liquid form, which is applied to the wall using a pump by pouring.
Its density ranges from 6kg/m3 to 60kg/m3, although usually it is 10-15kg/m3, in any case, these parameters are still used in construction today. In private construction, such material is used very rarely, although it gradually began to gain more and more popularity. For example, insulation timber house- lined with bricks can be produced in this way for intermediate insulation.
Expanded clay is produced by firing clay and/or shale, resulting in a light porous material in the form of oval granules of different fractions. It varies in density - 350kg/m3 to 600kg/m3.
But as the density decreases, its thermal insulation properties increase. Expanded clay is usually used for intermediate insulation of walls and for floors, as bulk material.
Of course, the best way to insulate the brickwork of a house is up to you to decide, but looking at the diagram above, you can at least roughly estimate the capabilities of different materials.
A very common method is when the insulation for walls outside and inside is mounted between the profiles, laying it close to them (foam plastic and extrusion) or pressing it with dowels using fungi, as in the top photo. This is certainly very convenient.
However, the problem is that the profile itself, especially if it is metal, is an excellent conductor. That is, the entire sheathing serves as cold bridges for the main wall. In some cases, of course, gaskets are placed under the brackets, but, nevertheless, certain areas (under the profile) are still left without proper protection.
But it is better and correctly to insulate a wooden house - lined with brick or simply made of brick with cladding, when the insulation completely covers the entire surface of the wall. This is not difficult to achieve - simply install the insulation before installing the profiles.
That is, first the brackets are mounted, thermal insulation is put on them, then waterproofing, and only after that the sheathing is installed. These methods are applied both inside and outside the building - the location does not matter.
Now let's see how to properly install polystyrene foam and extruded polystyrene foam inside and outside under plaster and putty. In such cases, panels of the required thickness are simply glued to the wall.
And, although there is a special glue for this, in most cases builders (myself included) use any brand of tile adhesive, although it is best to use it from the street universal formulations, for example, Ceresit CM 11. The panel here does not need to be completely smeared like ceramic tiles- it is enough to do this pointwise, in 10-15 places per square meter.
After the foam or extrusion panel has been glued to the wall, it is pressed with dowel mushrooms. For polystyrene foam, five points are optimally needed, and for extruded polystyrene foam, three (along the sheet).
To do this, make a hole in the wall through the panel with a puncher, and then insert a dowel into it, which must enter the wall at least 50 mm (otherwise it will not hold), and then hammer a spacer nail into it. By and large, under each fungus you need to cut out a hole with your own hands in order to recess the cap. But this takes too much time, so they are simply pressed harder against the insulation, compensating for the convexity with putty or plaster.
No matter how much we talk about home insulation, this topic will always be relevant. Many more houses need to be protected from cold and drafts, and each insulation has its own story. There are no similar houses, which means it is impossible to give ready-made answers to everyone. But some general provisions everything still exists. Insulating a wooden house from the inside and outside are different methods.
Of course, when insulating from the inside, there is a high probability that incorrectly performed work will shift the dew point, then the materials will become wet and the walls log house become covered with fungus and mold.
And if the house is made of wood, then the wood may rot. According to physical laws, couples always strive to go outside. In the same time cold air It will penetrate into the room through all possible cracks and cracks in the walls and exit through the ceiling. Wooden houses remove steam well due to the structure of the material. Therefore, insulation from the inside must be well thought out and carried out in compliance with all technologies.
There are situations when insulating a house with inside, this is the only possible way.
House insulation scheme
Some owners wooden houses cover it with bricks. Therefore, there will be no other options for insulating a log wooden house, only from the inside. With brick, the house really becomes warm, but due to the fact that the wood under the brick does not dry out and smolders. If you make a vapor barrier layer inside so that thermal insulation layer did not absorb moisture, it will be warm, but in return you will get a completely non-breathable room in which it will not be very comfortable to live all the time. And do not protect the tree from decay.
If you are insulating a wooden house, then it would be correct to do it yourself as follows:
Applying plaster You can also use ecowool to insulate walls. This environmentally friendly material that won't do any harm wooden house. The finish will look like this:
But if the house is not lined with brick, then it is possible to decorate the outside of the house.
External insulation, in addition to being more effective, also does not take away useful meters of the area of a log wooden house.
The choice of insulation will be yours. They also insulate houses, but synthetic insulation is airtight. It is better if you use Rockwool or Ursa mineral wool for a wooden house.
Starting to insulate the outside of a wooden house, we seal all the cracks in the facade with our own hands. Ideally, linen or jute tow is used for these works. You can use sealant. External insulation of a wooden house, between the beams using sealant, can be seen in the video:
Then you need to lay a layer of vapor barrier with your own hands. For this purpose, special membrane films are used. If the house is made of timber, then the walls are quite smooth and in this case you will attach the vapor barrier directly to the walls. But if you are insulating a log house from the outside, then you need to stuff vertical slats with your own hands to attach the vapor barrier layer. This layer is overlapped without gaps and secured with tape. It is necessary to achieve absolute sealing from moisture.
The sheathing is stuffed for laying insulation. The sheathing boards are attached vertically to the wall. The pitch between the boards is slightly smaller than the width of the insulation so that it can be inserted by slightly squeezing it.
It will help you to insulate the house from the outside. For insulation, mineral wool sheets must be laid in two layers. The joints of the second layer should not coincide with the joints of the first. This technique prevents the formation of cold bridges.
Exterior works The thermal insulation layer is covered waterproofing membrane. This material should not allow moisture to pass through from the outside. But, in turn, do not prevent the penetration of steam from inside to the street. This membrane is laid with your own hands, overlapping by 10 centimeters, and reinforced with tape.
A second layer of frame slats, thin and wide, is placed on this layer cake. This is necessary for installation air gap for air circulation.
When insulating from the outside, the lower part of the house is closed metal mesh to protect the insulation from mice.
The last step is decorative finishing Houses.
In order to estimate how much it will cost to warm houses made of timber, you need to calculate the amount of insulation; it will depend on the area of the walls of the house and the thickness.
Facing wooden building brick is a common occurrence. Brickwork allows you to update and give an old house a completely respectable look. However, often at the stage of this event, many do not immediately think about insulation, but during wintering it turns out that a brick wall does not protect the house from the cold. Insulating a wooden house lined with brick is not an easy task. Experts recommend thermal insulation of the building at the construction stage. facing works, but, unfortunately, not everyone listens to their opinion. How to insulate log house having brick facade? Let's look into this issue.
There are three ways to solve the problem:
The first method is the most acceptable from the point of view of heat preservation and safety of the wooden structure. But at the same time, choosing this option, you will have to sacrifice the aesthetic characteristics of the house, since all the beauty of the brick cladding will be hidden. In addition, a lot of investment in new finishing will be required.
The remaining two options have significant disadvantages, which we will discuss in more detail.
Many experts do not recommend filling the space between the walls with any thermal insulation material. And that's why. When facing a residential building or bathhouse with brick, be sure to leave a technological gap of about 25 cm. It is necessary for ventilation of the wooden triple. If the brickwork is made close to the wall, then after a certain period of time the wood will begin to rot, mold and mildew will appear on it, and it will all end in rotting of the wood.
This can also happen if the space is filled with insulation. Some, at their own peril and risk, resort to a similar method of thermal insulation, blowing into the brickwork holes penoizol. The material completely fills empty cavities, depriving wooden wall any ventilation. We do not recommend insulating a house in this way, as this can lead to unpleasant, but very predictable consequences.
Internal thermal insulation is also not the best option both for log and timber houses. This insulation has a number of disadvantages:
As you can see, it is extremely undesirable to insulate a wooden house from the inside if it is lined with brick. Moisture will stagnate in the wood, which will lead to the appearance of mold and mildew, and ultimately wooden structures may rot.
Regardless of what material and method of insulation is chosen, it is necessary to make holes in the cladding through which air will pass and ventilate the walls. In addition, the house must have a good ventilation system.
In this case, the house can be insulated with any materials suitable for.
You can insulate brick walls using:
For a wooden house, sawdust plaster, which consists of cement, clay, sawdust and paper, is best suited. Air passes through it, which allows the tree to breathe.
The work is performed in the following sequence.
