How to insulate a house outside with a brick. How to insulate a brick house

Building a brick house is quite popular throughout the Russian Federation, because brick walls have many advantages. They are reliable, fire resistant and able to stand long years... But there are also disadvantages, for example, they do not retain heat efficiently enough. The problem can be easily eliminated if additional external insulation of the brick walls of the house is carried out with special materials. How to insulate brick house almost every owner thinks outside.

Work in progress brick house, you have to spend a lot, which is why very often the question arises of how to carry out work on the insulation of a house with your own hands. Everything is quite simple, and if you thoroughly approach the issue, study all the nuances and choose the right material, insulate the house from silicate bricks, it will work without the involvement of hired specialists. The answer to the question of how to insulate a brick house from the outside, knows any seller of a hardware store.

There are a lot of insulation technologies, for a start we will consider a type of insulation for siding.

The question, what is the best way to insulate a brick house from the outside, is very common in specialized forums. It is worthwhile to thoroughly study all the information provided, and choose what suits you. The main division of insulation for walls occurs according to the principle of installation, there are those that require additional finishing, and which do not need it. There are simply a huge number of varieties of materials for insulation and sound insulation, many of them are similar in characteristics, and differ only in price and manufacturer.

• Mineral insulation (Minvata). It is very often used, due to the fact that the price for it is quite low, and the characteristics are suitable. For example, its thermal conductivity is 0.04 W / (m * K). In addition, it is quite environmentally friendly and even an inexperienced person can mount it. Minwata is capable of burning, so it has low level fire safety, which can be considered a minus, and during installation it will be necessary to carry out additional work related to moisture insulation of the walls, because the material absorbs condensation well.
• Expanded polystyrene (polystyrene). Thermal conductivity 0.036 W / (m * K). Lightweight, practical, with high moisture resistance. Just like mineral wool, it is environmentally friendly. The disadvantages of insulating a brick house outside with expanded polystyrene are toxic emissions during combustion, fragility, vapor resistance.
• Extruded polystyrene foam (penoplex), a warm brother of ordinary polystyrene. But it is produced using a different, fundamentally new technology. Thanks to this, it has improved characteristics of heat and sound insulation, as well as steam and water permeability. House insulation with foam is very popular.
• It is possible to insulate a brick house from the outside using modern methods, using foaming technology. Mounting polyurethane foam. The product is new, but has already conquered most of the market. Perfectly insulates and protects against moisture. Minus, the application is carried out using special equipment.

Two types of insulation that do not require additional finishing

• Another method of insulation brick wall from the outside, using a thermal panel under a brick, this is enough new technology... The main advantage is that there is no need to hide such panels under the siding. They have a beautiful appearance.

Insulation for a brick house using warm plaster

Installation scheme for siding

Surely not everyone knows how to properly insulate a brick house from the outside, or rather how exactly to mount the insulation. Installation, a group of heaters for siding, is fundamentally similar for all types of materials in this group. Before insulating a brick wall from the outside, it is necessary to expose the frame for the subsequent installation of siding. To do this, you will need to have:

• A hammer drill with an 8 mm drill, or an impact drill with a drill of the same diameter.
• Screwdriver.
• Construction level.
• Building corner.
• Roulette, hammer.

As a material for the manufacture of the frame, you can use a metal profile 60 * 27mm., Or wooden bars with a section of 50 * 50 mm.

Work should begin with cleaning the wall from anything that would interfere with the installation of the frame. Dismantle the ebb and flow from the windows. After that, you can start installing the extreme bars. If the wall to be insulated is flat enough, then the frame can be made of wood, and the bars can be fastened with a dowel - nails, through and through. For exterior walls with irregularities, it is better to use a metal profile.

The extreme bars are installed, using the building level, strictly vertically. After that, between them, for convenience, a lace is pulled, it is convenient to control the installation of the remaining bars along it. All installed bars should be at a distance of 60 cm from each other in the same plane.

Insulation, cut into pieces of the required length and fit between the bars. It should be fixed using dowels - nails for insulating materials, having previously drilled holes for them in the wall.

If additional vapor barrier is necessary, it is mounted before installing the bars, directly on the wall, and only then proceed to the installation of the frame bars. If a metal profile is used as a frame, the whole scheme looks about the same, only instead of bars, profiles are installed using special suspensions.

Insulation with polyurethane foam

The process of insulating the brick walls of the house from the outside, using polyurethane foam, is slightly different in the order of work. Start by cleaning the wall and removing anything that interferes correct installation frame. The next stage is marking and installation of hangers on the wall for mounting profiles. After mounting the suspensions, they start applying the polyurethane foam. The last step after applying the foam is the installation of the profiles. As in the case of the bars, the extreme profiles are first installed, and then the lace is pulled and the rest are mounted with it. The profiles must be in the same plane.

Important: The hangers, before applying the foam, should be bent in such a way that they are ready for the installation of profiles in them, if this is not done, then after applying the foam it will no longer work.

After installing the frame and insulation, the next stage is the installation of siding. The installation scheme depends on the type of siding panels, but general points are worth noting.

• Installation is carried out starting from the bottom of the house.
• Installation of the first panel is carried out strictly horizontally using a level.
• Each next panel is mounted on the previous one.

Finishing the facade of a brick house can be carried out using other technologies. For example, mount plates of mineral insulation (mineral wool) and then plaster and paint the surface. Or insulate the walls outside with foam and brick it.

Insulation of the facade of a brick house using a clinker thermal panel has a fundamental difference from the installation of mineral wool and other similar types of insulation. It consists in the fact that the installation of the frame and, accordingly, siding is not required. The pattern of clinker panels can be different, there are panels for brick, a natural stone, etc.

Before installation, as in the case of conventional insulation, the wall must be cleaned of dust, dirt and anything that may interfere with installation. Clinker panels are installed from the bottom up. The process from the outside resembles the assembly of a puzzle. First, the corners and the base are collected, then the inner part of the wall is gradually filled. Fastening takes place using dowel nails for insulating materials, as well as a small amount of mounting foam, which is applied under the insulation and then glues it to it.

Warm plaster

Abroad, for a long time, this type of insulation of the outer walls of a brick house is considered one of the best and is used almost everywhere. In Russia, the advantages of warm plaster have not yet been properly appreciated, although many builders are already using it in practice.

Warm plaster, has a composition almost the same as ordinary plaster, only instead of sand, bubbles of foam, or perlite or vermiculite are added to it.

Styrofoam - good insulation, anyone even unfamiliar with construction technologies man. The use of plaster with the addition of foam will allow you to insulate the house without high costs, and in a short time. Plastering does not require special preparation of the walls. Simply moisten with water and the mixture can be applied. Thermal insulation using warm plaster is quite effective because no joints, cracks or other defects remain on the wall through which heat can escape. Another indisputable advantage is the complete incombustibility of the plaster and the absence of the need to replace the slopes on the windows, which also allows you to save on finishing.

In addition to the article, watch the video:

Of course, you can also raise the temperature using conventional internal heaters. But electricity and gas are expensive these days.

Using them to overheat the room and combat low temperatures will only lead to a disproportionate waste of resources. In simple terms, you will be wasting resources. After all, such a situation could have been avoided.

For example, if you insulate a house with mineral wool, use polystyrene, Penoplex or any other material, then its internal temperature in winter, even without preheating, will increase by several degrees.

Insulation here will play the role of a kind of barrier for low temperatures. Due to its extremely low thermal conductivity, this material practically does not exchange temperatures, and therefore does not allow the structures near it to cool.

1.1 Types of heaters, their differences

The modern construction industry offers a huge number of insulation materials to choose from, which can be used as you please. It is possible to single out a few of the most important ones, but you will have to make the decision itself.

Only after evaluating a specific situation and your ability to really understand which one is best for each case. We will help you better understand the basic nuances of using heaters, their properties and details.

For external insulation, they are most often used:

• Styrofoam;
• Penoplex;
• Mineral wool;
• Penoizol;
• Glass wool on.

Polyfoam is the most common and popular material that is used to insulate facades almost everywhere. Some people say that you still can't find anything better than polystyrene, but this is not so.

Of course, foam has many advantages. It is convenient, lightweight, perfectly protects the house from heat loss, and is quickly assembled. And its price is quite low. With such quality characteristics polystyrene is cheaper than any other insulation. Is this not an indicator of quality?

But foam has its drawbacks. For example, low strength and susceptibility to combustion.The low strength of the foam plays a disservice to him. But for wall insulation, this indicator is not yet so critical. But the flammability of the plates is already a big problem.

Remember that you are in the business of decorating exterior walls. In case of fire, it is the facade that is the first carrier of fire across the floors. If the facade is on fire and there are no firefighters nearby, consider that the house is lost.

Penoplex is a type of foam. In fact, this is an improved polystyrene foam that has passed the extrusion process. Penoplex has better characteristics, better withstands loads and insulates the surface much better. But it costs more.

Also, Penoplex is not free from the disease of polystyrene - flammability. Although Penoplex is still a little more practical in this regard, because it does not burn, but melts. Which is already a big plus. But nevertheless, Penoplex must be used carefully and with a device of correct preparation.

Mineral wool especially needs no introduction - these are slabs or rolls of basalt fibers, which have excellent thermal insulation characteristics, can be installed by hand.

Mineral wool is more expensive than polystyrene, but it retains heat better, is completely environmentally friendly and allows the walls to breathe. In addition, mineral wool is a non-combustible material.

Its main drawback, as in the case of c, is swelling upon prolonged contact with water. And although most manufacturers have already learned how to solve this problem, we still do not recommend using mineral wool in a bath or other places with high humidity.

A little has already been said about penoizol above. After curing, Penoizol is very similar to polystyrene, but it also has some differences. It does not burn in fire and, moreover, extinguishes it by expanding its molecules.

Another thing is that penoizol can only be poured with professional equipment and it costs a lot.

Glass wool is a type of mineral wool insulation, but in all its parameters it is inferior to standard basalt wool... Therefore, now it is practically not used in construction.

2 Technology of exterior wall insulation

The process of warming itself, as mentioned above, does not have difficult moments or pitfalls. Although, building experience during the work is still required.

An interesting fact is that almost all heaters are mounted according to a general identical scheme. Only nuances differ, and even then not always.

Stages of work:

1. We prepare the surface, clean it from dirt.
2. We prepare the insulation.
3. We mount the insulation on the wall.
4. We are waiting for the solution to set.
5. We fix it to the wall with additional elements.
6. Close up the joints if necessary.
7. We apply the first layer of plaster and plaster mesh to the insulation.
8. Apply the second and third layers of plaster. We are preparing the base for finishing.
9. We decorate the facade with facing materials.

The above algorithm is a general scheme and there are many details in it, but it will do for understanding the whole procedure.

Polyfoam is most often mounted on a glue-type solution. The same is done with mineral wool, although this is not necessary. Additional fastening of the insulation to the brick wall is carried out by installing disc dowels. 4-6 dowels are enough for one square meter.

Sealing of joints is carried out on polystyrene and Penoplex, mineral wool does not need such actions.

Penoizol insulation is carried out according to a different procedure. Here, first, the frame is mounted under the insulation, then it is poured with the composition. After curing of penoizol, they are taken for plastering the surface and finishing. The last stages of work practically do not differ from those described above.

2.1 Installation of foam insulation on the walls of the house (video)

Despite the huge amount of modern building materials with the help of which residential buildings are being erected, brick is still becoming very popular in construction processes. However, after building a brick house with your own hands, you should remember about the need to insulate the walls outside, otherwise the microclimate inside the room will be disturbed. Today I will tell you what modern facing materials can be used to decorate the facade of a brick structure and how to insulate it.

The need for thermal insulation work

Insulation of a brick house outside

I, like any beginner, was very interested in why it was necessary additional insulation walls outside the house. Asking advice from his neighbor, who has always been engaged construction works, I got a specific answer. As it turned out, for high-quality thermal insulation, the thickness of the brick wall must be at least three meters - of course, this is irrational and meaningless. That is why those who build their houses out of bricks use more popular methods of wall insulation outside.

Important! Even at the stage of erecting a brick structure, one should think about thermal insulation measures. Thus, the insulation will be included in the overall project of the house and this will make the process more convenient.

In order to choose the most suitable type of insulation, it is worth considering in more detail all the options that you can do yourself.

External thermal insulation

We insulate a brick house using modern methods

Insulation on the outside is necessary for a good reason, which is the dew point. If thermal insulation is made for the walls inside the house, then condensation will collect between the insulation and the wall, which will lead to early destruction and mold. In addition, carrying out such work indoors leads to a decrease in area.

For a brick house, insulation materials such as:

1. Styrofoam
2. Ecowool
3. Mineral wool
4. Glass wool
5. Penoizol
6. Expanded polystyrene

Let's look at the features of each material in a small table:

View	Features, advantages and disadvantages
Mineral wool	It has excellent thermal insulation properties, but is often used for walls indoor space... Technical performance ranges from specific gravity material. Among the disadvantages: absorbing moisture, mineral wool begins to lose its properties
Ecowool	The difference between ecowool and mineral material is that it requires the use of a special impregnation. A cheap way to insulate a home, however, due to moisture permeability properties, it is better to use it inside the house
Styrofoam	It is still one of the most demanded methods of insulating various buildings. Convenient installation, use under plastering and low cost speak for themselves
Fiberglass	If you decide to decorate the walls with your own hands, then it is better to choose a different type or still use the services of professionals. This solution is necessary due to the toxicity of fiberglass. In all other respects, the material has good thermal insulation characteristics and therefore it is often used for mountains and attics.
Penoizol	An innovative material that is used not only as insulation, but also as a repair material. If, for some reason, the layer of mineral wool is damaged, or rodents have gnawed holes in the foam, then penoizol will help to qualitatively close up the gaps that have appeared
Expanded polystyrene	Used both outdoors and indoors. It is slightly inferior to mineral wool. Does not absorb moisture. However, it has flammability properties and is not a vapor-permeable material

Outdoor technology

We insulate the walls of a brick house

There are several technologies by which you can make thermal insulation outside or inside a building. They all differ from each other and therefore each of them should be familiarized with in advance:

1. Sandwich - thus, the process of thermal insulation of a brick structure was laid down at the stage of wall construction
2. A wet facade is a boring method for everyone, when a heater is attached to the wall, after which it is covered with a layer of plaster, before that it is reinforced with a special mesh
3. Ventilated - very common recently, as it allows not only to produce thermal insulation, but to equip the facade and completely transform it. This is very beneficial when old walls have already lost their appearance.

Among other things, the second and third options can be performed independently at any stage, and not only during the construction of houses.

Important! If the house has lost its appearance, then the arrangement of the ventilated facade will allow not only transforming it, but also radically changing it. There are enough siding panels on the market today that perfectly mimic how brickwork, and natural wood or ship timber.

Brick ventilated facade

Ventilated facades for brick houses

Modern materials that are used for thermal insulation of brick structures can be quite expensive, especially if you have chosen a ventilated facade for your home. Definitely, with this method, you will have to use siding trim. Therefore, having completed all the work outside with your own hands, you will be able to save additional funds. By the way, when arranging a ventilated facade, it is possible to use glass wool slabs as insulation for walls.

Arrangement of a brick structure in this way occurs in the following sequence:

• To begin with, the surface is cleaned of dirt, dust and greasy stains
• Then the lathing is attached, which can be made using wooden beams or a metal profile. For myself, I chose the metal profile, since it is not subject to decay. The distance between the guides should be such that the insulation plates enter with little force, that is, close
• Do-it-yourself fastening of thermal insulation plates with the help of adhesive mortar and umbrella dowels
• When the insulation has been carried out, a hydro-barrier should also be made, after which you can begin the final finishing of the facade of the brick structure using siding panels

Insulation from the outside in this way occurs much faster than the usual plastering of walls.

Outcome

Warming a house with foam

Self-insulation of the house outside can be done independently. An abundance of construction and thermal insulation materials allows you to choose the most interesting in terms of work and at a price, thus it becomes possible to decorate the facade with any technology. Do not forget that for high-quality processes, you should choose good materials and use tools that simplify all stages of wall insulation. Do not forget that all processes are best done in warm and dry seasons, exclude rainy and too hot weather, as this can negatively affect the finish. Brick buildings require a serious approach, both in the construction process and in matters of insulation, so think over all possible options in advance so that you do not have to redo all the stages later.

To make living in the house cozy and comfortable, you need to take care of thorough insulation of the brick house from the outside. And although the brick is vapor permeable building material, builders use a heat insulator when insulating a brick house, which still has an increased level of vapor permeability. Today, various modern methods are used to insulate a brick house from the outside, thanks to which it is possible to achieve the best result in terms of heat preservation. Also for house insulation, it is worth using for window insulation.

For thermal insulation of brick walls, various modern materials are used today, thanks to which it is possible to select a specific insulation technology. This will allow you to achieve maximum comfort in the house and at the same time not spend too much money in financial terms. The following insulation technologies remain the most common:

Materials

To spend external thermal insulation brick house, you can use materials such as mineral wool, polystyrene and expanded polystyrene.

Styrofoam

The use of foam is the modern and most popular method of insulating a brick house. This is due to the fact that the material retains heat well and is inexpensive.

Polyfoam for insulation of a brick house

But how to insulate the box of an entrance metal door with your own hands, and what materials are most suitable for this, you can read

In order to insulate a brick wall with foam, you must use the following instructions:

1. Remove debris and dust from the wall surface, level it carefully and apply a primer.
2. Dilute the glue, apply it to the insulation sheets with a spatula.
3. Apply the styrofoam to the wall surface and then press down firmly. Fasten the sheets at 5-6 points using a dowel-nails.
4. After 3-4 days, the sheets are completely dry, so you can remove the cracks with polyurethane foam.
5. Eliminate seams and irregularities using adhesive solution.
6. Reinforce insulation sheets with a special mesh. Its installation takes place on glue. The mesh is installed with a slight overlap.
7. When the insulation is dry, you can proceed to the installation of the finishing facade cladding.

Expanded polystyrene

Today, very often inexperienced people argue that foam and expanded polystyrene are the same materials. But this is far from the case. The materials in question are simply made from the same raw materials, but the methods of their production are different.

For the production of foam, a dry method is used. The process of processing the pellets is carried out with steam in order to obtain a reliable adhesion. But expanded polystyrene is obtained by extrusion, when the granules are melted to a uniform consistency. This way you can insulate entrance metal double doors.

Expanded polystyrene for home insulation

In terms of strength, density and sound insulation, expanded polystyrene is a couple of times superior to foam. Such a heat insulator is convenient for installation under siding and other materials for final finishing. The insulation process boils down to the following:

1. Clean the surface of the wall from debris, plaster and dust. Apply the putty to the places where there are cracks. Primer the wall.
2. Install the starting profile. Its fastening should be done with anchors, glue or special pastes. The glue is distributed in the middle of the insulation and along its perimeter. For maximum coupling, it is worth using the dowel-nails.
3. Seal the joints between the plates using polyurethane foam.
4. Install a reinforcing mesh on top of the insulation. It must be protected from the influence of acids and alkalis. Fix a galvanized corner in the corners to give the entire structure strength.
5. The fastening of the reinforcing mesh is carried out using an adhesive, and on top, apply another layer of adhesive.
6. Wall treatment with primer and plaster. You can give the plaster a different texture, thereby improving the appearance of the building.

Mineral wool

To insulate a brick wall from the outside with mineral wool, you need to use the following instructions:

But how the insulation of a cold attic floor with mineral wool occurs can be read

Thanks to a wide selection of modern materials for insulation, it is now completely easy to isolate a brick house from the cold and keep it warm for a long time. When choosing a method and material for thermal insulation, it is necessary to take into account the operating conditions and climatic conditions in your region. If you live in the northern regions, then it is worthwhile to carry out thermal insulation in 2 layers, otherwise you simply will not be able to get the desired effect.

A brick structure is a solid and durable housing. But this material has increased thermal conductivity. And if the walls are not thick enough and the house is cold, people have the question of how to insulate a brick house. It is better if this is incorporated in the building project and is done during the construction process. But what to do if problems arose during the operation of the building. Read on ...

In modern realities, a wall of ceramic hollow bricks 60 cm long does not retain heat sufficiently. Only increased masonry, which creates an additional load on the foundation, or the use of insulation create the conditions for the fulfillment of modern building codes and help to improve the operational characteristics of the building.

According to Russian building codes, for the Moscow region, the required wall thickness of ceramic hollow bricks should be one and a half meters. By applying 10 cm of expanded polystyrene on the outside, we get a 35 cm thick masonry that meets the requirements.

Walls are made of hollow or solid bricks. When laying, various solutions are used. And the structure of the masonry can be either solid or with an air pocket (well). Hence - different requirements for wall thickness and insulation. Insulation of brick walls requires calculation of the thermal insulation layer in terms of thickness and method of placement, taking into account all factors.

How to properly insulate a brick house? For solid masonry - it is recommended to insulate from the street side. The thickness and type of thermal insulation depends on the characteristics of the enclosing structure, the climatic zone and the required thermal resistance of the wall cake. If the masonry is well, insulation can be done inside, between bricks or external insulation. The presence of heat-insulating material in the interlayer reduces the heat loss of the building, but the risk of moisture accumulation is possible.

The material for insulation and the thickness are selected on the basis and taking into account the vapor permeability of the layers of the finished wall structure.

Algorithm of actions for warming a brick house

Instructions for insulating a brick structure are as follows:

1. Choose the appropriate insulation available in your area.
2. Pick up finishing materialyou want to cover the thermal insulation with.
3. Choose a façade system that uses the previously selected insulation and decoration.
4. Determine the required value of the heat transfer resistance of the building envelope in your area. To do this, you need to know the number of degree days in your area. For example, for Moscow, the thermal resistance coefficient of a wall is at least 3.2 m2 × ° C / W.
5. Next, use a calculator for calculating insulation (for example, smartcalc.ru), where you enter the layers of the future wall. By the way, the calculator for many regions already contains data on the required thermal resistance coefficient and degree-day, you just need to select the city of construction.
6. If the wall is not warm enough according to the calculator, then either we increase the thickness of the insulation, or replace it with another one with a better thermal conductivity. If the building is just being erected, then you can replace the masonry mortar with a warm one, which will also give an increase in thermal resistance.
7. When the wall is warm according to the calculator, that is, not less than the required thermal resistance coefficient, then a check is made for the vapor permeability of the layers.
8. If the vapor permeability of the layers meets the requirement of increasing the vapor permeability of the layers from the room to the street side, then get to work.

Insulation suitable for a brick house

When choosing the best way to insulate, you need to consider the characteristics of each material. Thermal conductivity determines the required layer thickness. Also important are durability, performance, naturalness. Some of the materials can insulate a brick house from the outside, while others are used inside. The following popular types are used.

Sprayed (, ecowool).

• Polyurethane foam is originally a liquid component that is applied to a vertical surface, producing maximum thermal insulation. Before insulating a brick house from the outside, a frame is erected, into which it is poured and finished with cladding. And also the cavities in the walls are filled with polyurethane foam.
• Ecowool (cellulose wool) is a product of recycled paper raw materials. It is harmless to humans, resistant to microbes and fungi, non-flammable, impregnated with flame retardants (substances that prevent fire).

Plate heaters

Stone wool, foamed polystyrene foam, plate glass, are also insulated with extruded polystyrene foam. Basalt slabs made of fiber - fire-resistant insulation, which reduces heating costs.

Foam glass - insulation with a cellular structure. Produced in the form of slabs and blocks. And also does not burn, is environmentally friendly, is not affected by fungi, bacteria. Learn more about this material by reading our.

Insulation of a brick house with polystyrene is a reduced thermal conductivity of the walls, easy installation and relatively low cost. Disadvantages - flammability with the release of harmful substances, fragility.

House insulation with penoplex - effective heat preservation, strength, resistance to moisture penetration inside. (which is also the penoplex) insulate buildings, increasing the thermal resistance. The material does not crumble and is resistant to biological contamination. Most often used in the area of \u200b\u200bthe base.

Roll (glass wool, linen insulation).

Insulating a house with glass wool is inexpensive and easy, it perfectly insulates. For wall mounting, a crate is made, then cotton wool is installed. The cotton-lined house is covered with a windproof material and then a finishing material.
