What to choose: cinder block or foam block. What is better to build a bathhouse from: general information, features and recommendations, which bathhouse is better to build Which foam block is better for building a bathhouse

Traditionally, a bathhouse is built from wood, but today it is very difficult and very expensive to find a good master carpenter who can competently build walls. Therefore, they are increasingly used for the construction of baths building blocks. Today there are many types of them, they have advantages and disadvantages, but their main advantage is that having at least some construction experience or friends who are builders, you can build both walls and piers yourself. And since most of the blocks are light in weight, this means that the foundation can be made lightweight, which saves time, effort and money.

Aerated concrete – refers to cellular concrete. It is made from cement, special foaming agents and quartz sand. This composition is poured into molds and water is added. As a result of the reaction, foaming occurs and the mass fills the mold. To give the material greater strength, the resulting blocks are treated with steam in special autoclaves. At high blood pressure under the influence of steam, quartz sand forms new strong compounds. Essentially it is a synthesized fake diamond high strength.

Aerated concrete block. The color of the block is closer to gray, so the main filler is cement

For construction load-bearing walls and partitions, it is advisable to choose autoclaved aerated concrete, but for insulation you can use non-autoclaved one - it is cheaper, but its strength is lower. Aerated concrete blocks come in different densities:

from 0.3 to 0.5 t/m 3 is used for thermal insulation;
from 0.5 t/m 3 and higher (up to 1.2 t/m 3) can be used for the construction of walls.

For the construction of small buildings, you can use aerated concrete grade D500 (density 0.5 t/m3) - it can well be used for the construction of boxes and for the construction of partitions, and costs significantly less than brands with a higher density. When erecting bathhouse walls, to reduce the consumption of blocks, they are placed on edge, so the wall thickness is about 200 mm. This is quite enough, since the block retains heat well, especially since the walls will be insulated.

The advantages of aerated concrete are its relatively low weight, ease of processing (it can be cut with a hacksaw or drilled a regular drill), does not burn and becomes more durable over time. Disadvantages are relatively high hygroscopicity when using low-quality material and a fairly high price. In order to reduce the amount of absorbed moisture, special additives are introduced into the composition of aerated concrete. It is recommended to lay aerated concrete blocks using special glue. When cement is used, they absorb moisture from the solution, which causes the thermal insulation to significantly deteriorate.

Gas silicate The main binding material differs from aerated concrete: for aerated silicate it is lime (62% quartz sand and 24% lime), for aerated concrete it is cement (up to 60%). Moreover, gas silicate is produced exclusively in autoclaves. These materials differ in color and hygroscopicity: aerated silicate is always white and actively absorbs moisture, as a result of which it can be destroyed, while aerated concrete simply allows moisture to pass through, maintaining comfortable humidity in the room, and if you choose from these two materials, then it is better to use gas concrete.

The gas silicate block has White color, so the main material is lime

Detailed information about construction from gas silicate blocks you can find in the video.

Foam concrete - one of the varieties of cellular concrete. It is made from a mixture of sand, cement and water, into which foam is mixed from a special foam generator. The manufacturing process is simple, allowing it to be produced privately. This is where the danger lies: there is a high probability of purchasing low-quality material, which will quickly begin to collapse.

The advantages of foam concrete include its lower cost (compared to aerated concrete) and better water resistance. Comparison of gas silicate and foam concrete blocks, see the video.

Cinder blocks made from poured concrete mortar slag - waste obtained after the combustion of coal or other materials. This type of material is the cheapest, but there is one feature: the slag should not be allowed to sit for a long time. less than a year, otherwise it allocates harmful substances.

Cinder blocks are the cheapest type building material

Sawdust can be used as a filler in the manufacture of building blocks. In this case, the material is called “sawdust concrete”. This material is easy to cut and drill, and has 2 times the thermal conductivity of brick. In addition, it is environmentally friendly and non-flammable (sawdust is insulated with a layer of concrete), and is lightweight. The disadvantages include a fairly high absorbency, but it can be reduced by almost half by pre-treating the sawdust with water-repellent solutions or by waterproofing the walls.

Expanded clay concrete - a material that in most cases replaced cinder block. In this case, the filler is expanded clay - foamed and fired clay. This material is absolutely non-toxic, almost does not absorb moisture, and has excellent heat-insulating properties. Expanded clay concrete blocks have relatively light weight, which makes it easier construction works. , more practical than foam blocks or aerated concrete: less heat-insulating materials are required and it is easier to install fasteners.

The thermal insulation properties of expanded clay concrete depend on the filler fraction - the larger the fraction, the better thermal insulation, but less dense. When building a bathhouse from expanded clay concrete, it is better to carry out insulation from the inside of the room (they recommend a layer of basalt wool, on top of which foil paper is laid with an air gap of 2.5 cm to finishing materials). The table shows some block parameters that will help you decide which one is preferable for you.

Ceramic blocks

I would like to say a few words about the possibility of using ceramic blocks to build a bathhouse. IN Lately You can see an advertisement for this building material, which claims that a ceramic block is much stronger and warmer than ordinary brick. As laboratory tests and inspections of objects built from ceramic blocks show, everything is not as good as the manufacturers are trying to present.

From what we saw above, we can conclude that ceramic blocks should not be used when building a bathhouse.

Features of building a bathhouse from blocks

Any construction begins with choosing the type of foundation. If you decide to build a bathhouse from blocks, you should stop at or - most blocks are light in weight, and bathhouses are usually a one-story structure and there is no need to spend extra time, money and effort on making a more complex base.

Laying blocks is carried out by analogy with brickwork, with the only difference that it is advisable to lay a metal mesh every 2-3 rows. It will add additional rigidity and strength to the entire structure. To make the work easier, it is very important to lay out the first row of blocks evenly. They need to level and compensate for all existing unevenness in the foundation. At the very top you can attach a crown made of timber, to which it will be convenient to attach rafter system and the base of the roof.

For insulation, it is advisable to use a layer of basalt wool, on top of which a foil film or vapor barrier membrane is laid. It is advisable to provide a gap between the foil (membrane) and the finishing materials by filling the slats with a thickness of 2.5 cm and then attaching the lining to them.

Most units require exterior wall finishing. Here everyone chooses to their own taste: you can plaster and paint, cover it with finishing stone or brick, etc. You can decorate the walls with siding, but for better ventilation there should be a distance from the wall to the siding (for foam concrete at least 5 cm). The roof for a bathhouse made of blocks can be any - to your taste without any special restrictions.

The first question that arises at the stage of preparation for construction work is the choice of material for the construction of walls. There are many options on the market and it is not easy to find yours among them.

One of the most popular wall materials They count foam blocks and cinder blocks. They have different technical characteristics and prices. To answer the question of which material is better and cheaper, it is necessary to analyze their advantages and disadvantages and position in the market.

Foam concrete is cellular concrete obtained through the hardening process of a solution that contains cement, sand, water and foam.

Foam blocks are a hardened mixture of binder, siliceous component and air cells that are formed due to the action of foaming agents. It is the latter component that ensures uniform distribution of air in the blocks. They are considered lightweight, warm structural building products.

They burn very poorly and protect other materials from fire. Houses made of foam blocks will be warm and reliable, and during operation they will allow you to save on heating the building. It is important that their thermal conductivity and volumetric weight are several times lower than that of sand-lime brick.

Foreman's advice: for laying load-bearing walls (internal and external), partitions of low-rise buildings, it is better to use foam blocks with a density of at least 500-500 kg/m³.

Cinder blocks are made from cement, sand, water and a special filler (usually blast furnace slag or expanded clay chips). They have good technical characteristics, but some significant disadvantages require a special approach to their use during construction. The owner needs to take care of high-quality waterproofing, insulation of walls and roof.

But this material is cheaper and easy to install (even a non-professional can do it). A cinder block bathhouse requires careful finishing of the interior walls. First attach to the surface wooden sheathing, then insulation, foil and on finishing stage- wooden upholstery.

Foam and cinder blocks have different technical characteristics and design capabilities. But if you follow the construction technology and choose the right product according to its characteristics, the selected building material will perform its task efficiently.

Foam block has better properties, but it costs significantly more. Cinder block is cheaper, but has some disadvantages that need to be compensated for by good thermal and waterproofing. The choice should depend on the financial capabilities of the construction site owner and housing requirements.

Cinder blockFoam blockConclusion

From the author: We welcome you, dear reader. In the article we provided comparative analysis the two most popular building materials so that you can decide on the choice: cinder block or foam block, which is better for building a house, garage or other building.

Source: http://sarstroyka.ru

If you asked me to express my opinion on the construction of houses, my choice would be clear: brick.

But our article is not about bricks, therefore, dear reader, opt for foam blocks. In short, foam block is better. At this point you can finish reading the article - and go to the warehouse store for the necessary building materials.

But still, not so fast. It’s worth finding out why foam block is still better.

To do this, we will divide our article into three parts. In the first, we will describe the advantages and disadvantages of slag blocks, in the second, we will characterize the foam block, and in the third, we will provide links to useful articles that will be useful to you in further work. That is, you will find out what you have to do after you build a structure made of cinder block or foam block - insulation, wall decoration, and so on.

Let's get started.

cinder block

A fairly popular material that has been used in construction for quite some time.

Not since ancient times, of course, but during massive construction during the Soviet era, this building material managed to prove itself well. It is quite strong, relatively durable, but most importantly, it is easy to manufacture and therefore cheap. Houses with cinder block walls still stand in their places.

But, naturally, their condition often leaves much to be desired. I wouldn’t like to use a cliched phrase and overly dilute our text with “water,” but “there could be many reasons for this.” The article “How to strengthen a wall from the outside: the second life of your home” describes the process of reconstructing cinder block walls, so we will not cover this topic in detail here.

Source: http://skorobogatko.com.ua

There is no single GOST for cinder block. Therefore, the weight of each element may vary. You can buy cinder blocks in warehouse stores, which are located in any more or less large locality in our country.

Let's name the advantages of cinder block:

relatively low cost. In the production of cinder blocks, a “secondary” material is used - slag.

However, this is clear from the name. Now you know what is cheaper. More specifically, the price of cinder blocks in Russia is this moment is about 20–30 ₽ per piece; the speed of construction of the structure.

Here, it is rather appropriate to compare this material with brick. Elementary, Watson: where you would put about seven bricks, you will put only one cinder block. But in terms of weight, naturally, one cinder block is not equal to seven bricks.

Bricks are heavier; theoretically non-toxic. In its production /must not/ be used materials that are harmful to the body of people and animals. But, again, theoretically, anything can be mixed into its composition.

Therefore, before purchasing a batch of this building material, it would be a good idea to check the certification to ensure the quality of workmanship; thermal insulation. The material itself can serve as a good heat insulator due to its structure. And in combination with home insulation produced using the right technology, you can be sure that you will not freeze in the cold season; versatility.

It is impossible to say unequivocally what is more practical: cinder blocks or foam blocks. The fact is that both of these materials are suitable for building both a house and a garage or other building. In a word, both building materials are universal.

Let us separately highlight one more fact that undoubtedly deserves your attention. Cinder blocks are used in foundation construction. And quite successfully.

As often happens in practice, when pouring a foundation, various construction debris is often “buried” there, which, by the way, not only does not make the structure worse, but in some way makes it stronger and more durable. Of course, if not everything was thrown there in a row, but various fragments of bricks, perhaps metal (for example, unnecessary pipes). So, cinder blocks also make a reliable and durable structure.

Now let's discuss the disadvantages of cinder block:

low sound insulation. More precisely, the lack thereof.

Due to its structure, the material is practically no obstacle to sounds, say, from the street. Therefore, if you built a house from cinder blocks, you will have to get used to the noise of cars passing along the street. Although, there is another way out - sound insulation.

But this is natural extra work, time and, of course, additional costs. Therefore, cinder block is more suitable for the construction of garages or other non-residential buildings. Or for erecting walls inside a house from, say, foam concrete; unattractive appearance.

If a brick wall, for aesthetic reasons, can be left without finishing exterior finishing, then a cinder block structure will not look very attractive. Let's just say, for a rare fan. Therefore we will have to do exterior decoration using siding, brick or other material.

At the same time, it is possible (and necessary) to lay insulation (foam plastic, extruded polystyrene foam, mineral wool) between the wall and the finishing material. But, again, if not a house is built, but a garage, there will be no need to bother with finishing. A garage is just a garage; subsequent processing is difficult.

To lay the necessary communications in the room with your own hands, you will have to try hard. It is better to hire professionals who will do the work for you; the need to build a reliable foundation. This cannot be called a disadvantage, since the foundation must be reliable.

That's why it's the foundation. But if you are planning to build a two or three-story structure on loose soil, this is not the best idea, since there is a risk that the building will “float”; the walls need to be waterproofed. The fact is that cinder block very actively absorbs moisture.

But for buildings (especially residential ones) this is completely useless. Moisture both destroys building materials and promotes the formation of fungal colonies, which also destroy building materials. In addition, mold is hazardous to health.

Well, we have analyzed the properties of the stone block. For construction, this material is not bad, but not excellent either. Personally, I wouldn't build a house out of cinder block.

But the garage is another matter. By the way, my garage is made of exactly this material. And they built it without much haste - in less than a couple of weeks (taking into account the time spent on cladding).

Enough about cinder blocks. Let's move on to foam blocks.

Foam block

We will not go into consideration of the technology for producing foam blocks. And this doesn’t make much sense in the context of our conversation today. Let's limit ourselves to noting: the foam block is obtained by foaming concrete using special equipment.

Most often this material is compared to brick. Many builders say that these materials are identical, but their main difference is the price. Foam block is not completely identical to brick, and its price is actually lower.

Let's consider the advantages of foam block:

low cost compared to brick; low thermal conductivity. The material itself is a good heat insulator.

Therefore, do not ask whether foam blocks or cinder blocks are warmer - in this regard they are identical; versatility. The material is suitable for the construction of structures of any type. Just like the shalkoblok; light weight.

You can build a house or garage from foam blocks on almost any soil and not be afraid of “seismic activity” on a local scale. But the foundation must still be strong and reliable - no one can cancel this; a sufficient level of sound insulation compared to the previous material; relative ease of processing. Conducting communications will not be as difficult as in the case of a cinder block.

Now is the time to reveal the flaws. In reality, these shortcomings are relative in nature and cannot be called shortcomings of the material. But in order not to write a slogan here like “Foam block is ideal!”, we will still present them for your consideration:

if the batch is defective, this is critical.

It is clear that defects are bad for any building material, but if you build a structure from foam blocks, the production technology of which has been violated, you will be in trouble. The material will simply begin to crumble. Although, you can identify defects at the procurement stage.

Just be careful; the material “does not like” moisture. More precisely, he loves, but for us, as residents of the house, this is not very good. Foamed concrete blocks actively absorb moisture, so proper finishing of the walls after construction is necessary.

OK it's all over Now. The material has no other significant disadvantages. It is quite easy to process, serves as a good heat insulator (but this does not mean that the house will not have to be insulated at all), and also has soundproofing properties.

As for the cost, one foam block with parameters 600×250×50 mm/5 kg averages 30–50 rubles. As we can see, it is more expensive than a cinder block.

But in terms of technical characteristics this material is superior to the previous one. But if you are not building a house where you will subsequently live, but, say, a garage or a greenhouse or even country house Where you will only occasionally spend the night, you can use a cinder block. Here it is appropriate to be guided by the advertising slogan that came to us from the era of perestroika: “Why pay more?” But if the house is built for permanent residence, - build from foam blocks (or better yet, from bricks).

Today, building houses, garages, fences and other structures is not difficult. The market offers a variety of materials for construction that even a non-professional builder can use.

Houses are built mainly from brick, wood and no less popular materials, which include cinder blocks, aerated concrete and foam blocks. If everything is clear with brick and wood, then the remaining three materials still cause mistrust. Only a specialist who understands the composition of the given materials and their technical characteristics can answer the question of which is better - brick or cinder block, foam block or aerated concrete.

If before construction the question arises about choosing suitable material, you should thoroughly study all the materials offered. Let's try to determine: what are the differences between aerated concrete, cinder block and foam block. After all, these seemingly identical materials contain a lot of distinctive features.

Aerated concrete in construction

Aerated concrete has become popular relatively recently. Perhaps its popularity was influenced by the global crisis: since it has a fairly low cost, anyone can buy it. Despite the cheapness of the gas block, it has a number of positive features.

The advantages of aerated concrete include:

additional insulation

As for the shortcomings, they are also present. Moreover, all its negative qualities completely coincide with brick.

The main disadvantage that is worth paying attention to is their moisture absorption. This feature characterizes the absorption of moisture into the material, which is why the house may be damp for several days after construction is completed. Also in winter, icing of the outer wall is observed, which leads to a decrease in heat in the house.

Return to contents

Before answering the question of which material is better, you should fully understand the advantages and disadvantages of cinder block.

They will help you accept correct solution when choosing.

Cinder blocks are used not only in the construction of walls, but also for laying the foundation.

Its low cost is explained by the use of waste materials in production.

The blocks are made from concrete mixture with the addition of the necessary fillers. The weight and dimensions of the block may vary slightly. Here the standards are not met, since production is carried out not only by enterprises, but also by private entrepreneurs.

A distinctive feature of cinder block is its low thermal conductivity in comparison with brick or foam block. But thermal conductivity also depends on the filler, so when choosing, you should pay attention to its composition. According to experts, cinder blocks made of lime are considered the most durable.

The advantages of cinder block include:

positive quality

This material has disadvantages:

low level of sound insulation; after construction is completed, it will be necessary to carry out external and internal finishing; it makes it difficult to install internal communications; cinder blocks are afraid of water; under frequent exposure to it, the service life of the blocks is noticeably reduced.

When giving preference to the material described, it should be borne in mind that it may be necessary to overlay external walls brick, and this leads to additional financial costs.

Initially, “small towns” – wooden chocks – were used as point supports. But over time, any wood rots and requires replacement, so it was replaced by concrete structures.

This type of foundation is good because its construction can smooth out the unevenness of the site: it is enough to deepen a row of foundations to the required level to obtain a level surface. Can be used in the construction of small one-story baths.

Pile gained great popularity, especially due to the fact that screw piles can be installed even in winter. Therefore, construction of other types of baths for which such a base is suitable can begin at any time of the year.

The essence is to twist specially made piles at equal intervals (the distance between them is regulated depending on the massiveness and size of the structure).

Pile foundations also include foundations made from bored piles; we recommend reading about this, as well as about pile foundations in general.

What is better to build a bathhouse from: the main question is the walls

The wall material directly determines:

type of foundation required;
types of insulation and their application (outside or inside).

Therefore, it is so important to understand the walls in the topic “What is the best material to build a bathhouse from.”

Blocks: what material are they made of?

Block baths have won love among builders and buyers for good reason: they are characterized by incredibly short construction times with a relatively low cost. If you have a certain amount of skills, you can independently cope with the construction of a bathhouse from blocks. The most common types of blocks include:

foam concrete;
expanded clay concrete;
aerated concrete;
gas silicate;
cinder blocks.

Block baths require decorative finishing, because... do not differ in special aesthetic qualities in their “pure” form.

Which blocks are best to build a bathhouse from?

Ease of manufacture cinder blocks leads to the development of handicraft production, which cannot maintain product manufacturing standards. However, they undoubtedly have one advantage - low price.

Gas silicate the blocks are highly hygroscopic, require high-quality hydro- and vapor barrier, in addition, it is important not to make a mistake in its types: they all have different parameters for strength and thermal insulation. Use for bathhouse construction is not always justified.

Therefore, answering the question: which blocks are best to build a bathhouse from, we say: they fit well aerated concrete and foam concrete– they are easy to use, light in weight and easy to process. The cellular structure guarantees excellent thermal insulation properties, but also requires high-quality vapor barrier and waterproofing.

Tree

The tree is one of the most traditional materials, which meet all environmental requirements. Today the industry offers different types processed wood:

log(the most thorough material);
timber(processed wood of certain dimensions, for example: 100*100, 200*200);
carriage(a log hewn from two opposite sides - especially popular in Scandinavian countries);
double beam(represents 2 boards with grooves, between which insulation is placed, most often mineral wool or ecowool).

What kind of wood is best to build a bathhouse from?

The main division of wood building material lies in the nature of the logs used: resinous (coniferous) or non-resinous (deciduous) species.

What kind of wood is best to build a bathhouse from? Made from dense and well dried. Aspen is one of the non-resinous species, but such wood is very expensive, and oak is especially expensive. The fundamental difference is that poorly dried coniferous forest will long time resin (smudges of resin will form).

Therefore, they are most often built from pine and other coniferous species. In addition to a lower price (compared to the same aspen), they have such advantages as:

smooth and straight trunk;
easy processing of logs;
knots do not spread inside the wood (as, for example, in birch);
retain heat excellently (aspen is significantly inferior in this characteristic).

In view of the above, if you chose pine as the answer to the question: what kind of wood is best to build a bathhouse from, then you should give preference to well-dried wood.

From which forest? is it better to build a bathhouse? It would be desirable if this were winter forest (that is, chopped in winter and dried during the summer under cover).

REFERENCE. Dead wood is periodically offered as a building material, and this is to some extent justified, such wood has a high density. But he demands special processing antiseptics, otherwise there is a high chance of damage by rot in places of high humidity.

Timber or log: what to make a bathhouse from?

Each of these materials has its own advantages:

log sauna does not require additional thermal insulation, except for inter-crown insulation;
timber bathhouse It’s easier to lay than from a log; a minimum qualification is enough to lay the beam with minimal gaps.

Therefore, when choosing a material and what to make a bathhouse from, use additional information from.

Which timber is better to build a bathhouse from?

To build a bathhouse, it is best to use well-dried timber: it will shrink less, and there will also be a lower risk that the timber will begin to bend. High humidity timber reduces its thermal insulation properties.

Which timber is better to build a bathhouse from? For, based on the type of wood from which it is made, you can use the table below:

According to the results of many studies, double timber is ahead of similar indicators ordinary timber, but used as internal insulation mineral wool casts doubt on its use in the construction of a bathhouse.

Useful video:

Watch a video explaining the benefits of double timber. It seems reasonable to conclude that the technology is more suitable for homes than for baths.

For good warm bath It is best to use a 200*200 beam; the use of a thinner beam or half-beam (for example, 100*50) will require significant financial costs for external insulation. Although, if the bathhouse is heated only in the summer ( country option), then not thick walls, 10 centimeters, may be enough.

Foam block

As already mentioned, it has a high ability to absorb moisture due to its porous structure, so proper vapor and waterproofing is required. About the benefits and strengths Foam concrete baths can be found in these articles:

, and .

Frame baths

They have gained great popularity due to the short construction time, as well as others that make it possible to carry out. You should be careful when choosing insulation for the frame, since a bathhouse is a building with increased temperature conditions use. Therefore, the insulation must be safe and not emit harmful substances when heated. You can read more detailed information in this article:.

Dedicated to choosing the type of foundation for frame baths.

Insulation

It was not for nothing that log bathhouses were so popular, because before there was no such assortment of insulation materials, so everyone made do with simple caulking: plugging cracks and gaps with natural materials: moss, flax, etc.

Bathhouses made of timber already require minor insulation from the outside, especially in areas with cold winters.

But during the construction of block and brick baths You can’t do without insulation at all.

What needs to be insulated in any bathhouse?

In any bathhouse, regardless of what building material it is built from, it is required. This is no accident: after all warm air always strives upward. If you do not insulate the ceiling, then all the heat will go outside. baths Frame baths have insulation already inside the frame, so additional insulation is appropriate if you are in an area with extremely cold winters. More .

Floor

Any floor needs insulation, especially if the foundation has not been insulated. Depending on the organization of the floor in your bathhouse (spill or non-spill), the choice of insulation depends. If the floor is torrential, then the insulation must be protected from moisture, otherwise when wet it will lose all its properties. More information .

Roof

Roof insulation will be needed if you organize attic floor, in this case you can use polystyrene foam or mineral wool.

Insulation from inside or outside

Most often, insulation is done from the inside; log bathhouses and saunas, which are used in winter in cold regions, are insulated from the outside. often combined with decorative finishing. provides the effect of a thermos and protects the wall material from damage high temperature. It should be remembered that.

A little about insulation

It is necessary to understand that you cannot purchase a batch of one type of insulation and use it to insulate the entire bath.

This topic is the subject of heated debate, which only flares up more brightly with the advent of the next new product on the insulation market.

What can you use to make a bathhouse quickly and inexpensively?

What can you use to make a bathhouse quickly and inexpensively? Choose one, or build it yourself from timber or. These materials require minimal qualifications and dexterity. Usage natural insulation materials will also reduce the cost of the project.

They are also popular because of their low cost and ease of implementation, we recommend that you familiarize yourself with them.

Conclusion

It is difficult to give a definite answer to the question: what is the best material to build a bathhouse from? As you can see, the choice is huge. It is worth focusing on your personal preferences and budget options. We have tried to provide you with a detailed section of information that will allow you to more easily understand this difficult topic and choose the solution you need.

In this article we will try to explain in an accessible and detailed way how to build a bathhouse from blocks. The use of this building material is completely justified, since it provides significant cost savings while maintaining the high performance qualities of the structure itself.

Moreover, special skills are not needed for such work - it is enough if you master the basics of bricklaying and basic finishing technologies.

Material for construction

The first question that we need to solve at the preparation stage is which blocks are best for building a bathhouse?

In fact, the choice is by no means obvious, since the modern market offers us several quite comparable options:

Aerated concrete. It is produced on the basis of cement and quartz sand with the addition of a special foaming agent. This component ensures the formation of an internal fine-cell structure, and steaming the finished blocks in an autoclave gives them strength.
The optimal brand for the construction of load-bearing structures is D500, but it is characterized by a fairly high cost.

Note!
Non-autoclaved blocks can also be used during construction.
They are not suitable for load-bearing structures.

Gas silicate blocks, unlike aerated concrete blocks, do not contain cement. Lime is used as a binder. The high hygroscopicity of the material makes it not the most best choice for the construction of baths and saunas.

Foam concrete is another cellular building material, which is characterized by its relatively low mass and high heat-saving rates. The composition of foam concrete includes sand, cement and special foam, which is supplied to the solution from a foam generator.
The properties of foam concrete are quite acceptable for construction, at least it absorbs less water than gas silicate. And the price of foam concrete modules is quite affordable.
Porous slag is used as a filler for cinder blocks. A special feature of cinder block is its low cost, but it transmits heat more intensely than previous options.
Expanded clay concrete blocks for the construction of baths are modules made of expanded clay, filled cement mortar. The high heat-saving characteristics of the material greatly facilitate the process of insulating it: the walls themselves cope with this task quite well.

In principle, the range is not limited to these varieties, but we have already listed the most popular items. In most cases, the choice will need to be made from these options.

Sequence of work

Laying the foundation

When we have chosen the type of blocks, we need to take care of preparing a reliable foundation. Most materials used for the construction of a bathhouse are characterized by high porosity and low mass, so the foundation should not experience any special loads.

And yet, a bathhouse cannot do without high-quality support:

For baths with relatively small sizes(up to 6-7 m along the long side), columnar or strip foundations are most often laid.
The columnar structure involves the installation of concrete supports at the corners of the building and at the junctions of the walls. It is also possible to support long straight sections with poles.

To ensure greater strength, the pillars are often connected with a reinforced grillage.
The strip structure is a trench up to 50 cm deep and 30-40 cm wide, filled with reinforced concrete. The trench runs under everyone load-bearing elements and ensures load distribution on the ground.
On complex substrates, pile supports are also used.

Regardless of the type of foundation, it must be raised above ground level by at least 40-50 cm. This is done in order to protect the hygroscopic building blocks from the penetration of soil moisture.

For the same purpose, it is necessary to ensure effective waterproofing: when we build a bathhouse from blocks, we must lay between concrete base and the first row of masonry is two layers of roofing felt.

Advice!
It is necessary to provide openings in the foundation for the removal of sewerage pipes.

Walls and roof

We carry out the laying of walls according to all the rules, always monitoring the quality of work using a level and plumb line.
Every three to four rows we reinforce the structure with welded metal mesh or reinforcing bars.
For registration window openings we use either wooden casings or special long panels (if necessary, you can cast them yourself).
We place metal pins with a diameter of 10-12 mm in the top row of blocks. We attach a wooden beam-mauerlat to them, which acts as a support for the roof.

Further, the instructions assume the installation of a rafter system made of timber and boards with a thickness of at least 20 mm. The roof in a bathhouse can be either gable or single-pitch: the first is more expensive, but more convenient to use, the second requires periodic snow removal in winter and needs additional waterproofing.

As roofing material you can use metal tiles, euro slate, etc.

Also at this stage of work we provide communications: electricity, water, sewerage, etc. For laying cables and pipes, it is necessary to provide openings in the wall enclosure.

Room decoration

If we want to build a bathhouse from blocks and make it as warm as possible, then in addition to choosing the material with the highest energy saving indicators, we must ensure effective thermal insulation.

Typically responsible for this interior decoration:

both from the attic and from the room. This will minimize heat loss, because hot air constantly rises. It is also worth taking care of internal insulation roof slopes - at a minimum, installing mineral wool panels and covering them with a windproof membrane will not harm.
It is better to make the floor concrete, insulated with expanded clay, foam glass or polystyrene slabs. The boardwalk must provide effective drainage.
We fill the walls with lathing from wooden beam. Between the segments of the sheathing we lay panels of basalt wool or similar heat-resistant insulation.
We cover the heat-insulating layer with foil material on top. The foil acts both as a reflector for infrared radiation and as a vapor barrier.
On top of the foil we install a counter-lattice made of thin slats, to which.

Advice!
The interior of the bathhouse should be finished according to the same scheme, but the thickness of the insulation may be different.
The most powerful layer of thermal insulation should be placed in the steam room - this way we can maintain a high temperature there.

External insulation is carried out if we erected the external walls in one block. For thermal insulation on the outside, foam concrete or aerated concrete blocks are most often used.

Conclusion

We hope that after reading this article, you will be able to choose which blocks are best to build a bathhouse from, which one to lay the foundation for, and how to build and finish the structure itself. Well, the video in this article and the application of the acquired knowledge in practice will help you finally understand all the nuances!

Traditionally, a bathhouse is built from wood, but today it is very difficult and very expensive to find a good master carpenter who can competently build walls. Therefore, building blocks are increasingly used for the construction of baths. Today there are many types of them, they have advantages and disadvantages, but their main advantage is that having at least some construction experience or friends who are builders, you can build both walls and piers yourself. And since most of the blocks are light in weight, this means that the foundation can be made lightweight, which saves time, effort and money.

Types of blocks, their characteristics and features

Aerated concrete – refers to cellular concrete. It is made from cement, special foaming agents and quartz sand. This composition is poured into molds and water is added. As a result of the reaction, foaming occurs and the mass fills the mold. To give the material greater strength, the resulting blocks are treated with steam in special autoclaves. At high pressure under the influence of steam, quartz sand forms new strong compounds. In essence, it is a synthesized artificial stone of high strength.

For the construction of load-bearing walls and partitions, it is advisable to choose autoclaved aerated concrete, and for insulation you can use non-autoclaved one - it is cheaper, but its strength is lower. Aerated concrete blocks come in different densities:

from 0.3 to 0.5 t/m3 is used for thermal insulation;
from 0.5 t/m3 and above (up to 1.2 t/m3) can be used for the construction of walls.

The advantages of aerated concrete are its relatively low weight, ease of processing (it can be cut with a hacksaw or drilled with a conventional drill), it does not burn and acquires greater strength over time. Disadvantages are relatively high hygroscopicity when using low-quality material and a fairly high price. In order to reduce the amount of absorbed moisture, special additives are introduced into the composition of aerated concrete. It is recommended to lay aerated concrete blocks using special glue. When cement is used, they absorb moisture from the solution, which causes the thermal insulation to significantly deteriorate.

The gas silicate block is white, so the main material is lime

You can find detailed information about construction using gas silicate blocks in the video. Foam concrete - one of the varieties of cellular concrete. It is made from a mixture of sand, cement and water, into which foam is mixed from a special foam generator. The manufacturing process is simple, allowing it to be produced privately. This is where the danger lies: there is a high probability of purchasing low-quality material, which will quickly begin to collapse.

The advantages of foam concrete include its lower cost (compared to aerated concrete) and better water resistance. Comparison of gas silicate and foam concrete blocks, see the video.

Cinder blocks made from slag filled with concrete solution - waste obtained after the combustion of coal or other materials. This type of material is the cheapest, but there is one peculiarity: the slag must sit for at least a year, otherwise it releases harmful substances.

Cinder blocks are the cheapest type of building material

Sawdust concrete is absolutely safe and environmentally friendly

Expanded clay concrete - a material that in most cases replaced cinder block. In this case, the filler is expanded clay - foamed and fired clay. This material is absolutely non-toxic, almost does not absorb moisture, and has excellent heat-insulating properties. Expanded clay concrete blocks are relatively light in weight, which facilitates construction work. A bathhouse made of expanded clay concrete is more practical than one made of foam blocks or aerated concrete: less heat-insulating materials are required and it is easier to install fasteners.

Construction of a bathhouse made of expanded clay concrete

The thermal insulation properties of expanded clay concrete depend on the filler fraction - the larger the fraction, the better the thermal insulation, but the lower the density. When building a bathhouse from expanded clay concrete, it is better to carry out insulation from the inside of the room (a layer of basalt wool is recommended, on top of which foil paper is laid with an air gap of 2.5 cm to the finishing materials). The table shows some block parameters that will help you decide which one is preferable for you.

Ceramic blocks

I would like to say a few words about the possibility of using ceramic blocks to build a bathhouse. Recently, you can see advertisements for this building material, which claim that a ceramic block is much stronger and warmer than regular brick. As laboratory tests and inspections of objects built from ceramic blocks show, everything is not as good as the manufacturers are trying to present.

From what we saw above, we can conclude that ceramic blocks should not be used when building a bathhouse.

Features of building a bathhouse from blocks

Any construction begins with choosing the type of foundation. If you decide to build a bathhouse from blocks, you should choose a strip or pile foundation - most blocks are light in weight, and bathhouses are usually a one-story structure and there is no need to spend extra time, money and effort on making a more complex foundation.

The laying of blocks is carried out by analogy with brickwork, with the only difference being that it is advisable to lay a metal mesh every 2-3 rows. It will add additional rigidity and strength to the entire structure. To make the work easier, it is very important to lay out the first row of blocks evenly. They need to level and compensate for all existing unevenness in the foundation. At the very top you can strengthen a crown of timber, to which it will be convenient to attach the rafter system and the base of the roof.
