Features of houses from gas silicate blocks

Know the features of houses from gas-silicate blocks are useful to any individual and not only the developer; We are talking about a number of subtleties of projects of houses and their construction. It is necessary to carefully study the possible options for the construction of one-storey and two-story up to 100 kV. M. and more. Additionally, it is necessary to pay attention to the interior decoration, and to even better know what to deal with – to familiarize yourself with the reviews of the owners.

Advantages and disadvantages

Immediately it is worth emphasizing that the application for decent thermal insulation in houses from gas-silicate blocks is quite justified. She is actually comparable to the characteristics of high-quality wooden buildings, even without taking into account additional insulation. Also in favor of such structures is evidenced by simplicity of work and relatively high installation speed. It is quite realistic, if you try, start working in the first half of summer and already before the start of the leaf Falls to instill in a fully equipped housing. Air exchange with an external environment is very stable and efficient, regardless of the season – which allows you to provide an excellent microclimate.

But still quite favorable conditions are achieved only when using good waterproofing. Inattention to her or the desire to save often and give rise to complaints of too cold house.

A common judgment about the simplicity of construction is also true – however, everything is resting in the geometry of blocks. Relatively easy to post the wall from the standard form modules. But if you seek some kind of delights, you will have to spend noticeably more time and overcome a number of problems.

The desire of manufacturers in every way to increase the heat-saving quality of their product is understandable. However, because of this, the carrying ability often suffers, and therefore it is important to carefully select a specific material. From other actual properties of blocks should be called:

  • ease;
  • excellent noise insulation (noticeably better compared to brick and concrete);
  • Full absence of toxic human and animal substances for the body;
  • optimal vapor permeability;
  • Small frost resistance;
  • Insufficient suitability for screwing and drivening fasteners;
  • incompatibility with cement-sand plaster;
  • The obligation to apply ordinary plasters in two layers.

Project Overview

For considerations of savings, quite many people choose one-story houses with an area of ​​up to 100 square meters. M. Such buildings are suitable for small families, and even for lonely people who seek to a disorder and comfort. They are often used in summer cottages. Yes, and the very possibility of placement on a limited area is also quite pleasant. A typical layout of such a dwelling means highlighting:

  • kitchen (optionally combined with a dining room or a guest zone);
  • living room (sometimes united with dining room);
  • bathroom;
  • the only bedroom (or paired bedrooms is the same approximately area);
  • The utility room (where infrastructure objects are placed, important household items and secondary unnecessary things).

The mentioned association of adjacent rooms is not by chance. It is only so possible to ensure the optimal functionality of buildings and at the same time not to inflate their metra. For visual separations often apply columns, low partitions, bar racks and other furniture.

An important point is also the use of built-in wardrobes. They allow you to accommodate many stored things that do not take an additional place.

And yet, as it were, in the house 6 on 8, let’s say, meters, it was not necessary to “climb” – it still needs to be separated by a sleeping and guest zone. This requirement is associated with elementary psychological and sanitary and hygienic nuances. Between them should be in any case the capital wall. When booking elongated in the length of the buildings, it is trying to clearly highlight the left and right wings. Then take guests and are collected in one part in the afternoon, and in the evening and night hours go to another wing.

In modern typical building, more and more attention is paid to the homework homes with a garage – and the arrangement of gas-silicate dwellings of this kind is not too different from the construction of frame buildings. An extension of parking space to the house allows:

  • Do not break the head where to take the platform for him on the site;
  • take advantage of common heating, electrical communications;
  • Simplify the garage equipment with water supply and sewage;
  • faster to fall from one zone to another;
  • Faster to leave and come.

The entrance to the garage boxes is recommended to be located on the same side as departure. Must be equipped with a tambour, insulating room from exhaust gases. Useful to bring the garage to the kitchen or utility room (pantry) to be less wearing heavy loads. At the same time, it is necessary to pay attention to fire standards – because the garage is a source of increased danger. Because the wall between it and residential premises is separated only by non-aggravated materials or materials with a high degree of fire resistance.

In some cases, it is appropriate to build a single-storey, but a two-storey house from gas-silicate blocks.

Note: to build even higher buildings from this material is not worth the fact that it is unsafe. No wonder such a limitation is established in ordinary building standards and rules.

Two floors are spacious and more convenient in everyday life. Important properties:

  • occupation of a smaller area at the same area inside;
  • Best view from the second floor;
  • Simplify zoning;
  • weak sound insulation;
  • Cutting useful area with a staircase;
  • difficulties with descent and lifting, especially for children, elderly and patients;
  • Difficulties with redevelopment.

With fairly large cash, you can equip a single-storey house with an area of ​​150 kV. m, even with a terrace and attic. It is possible to easily equip 2 or even 3 bedrooms. You can not save on the volume of kitchen and dining area.

Competently prepare the project will be able to only professional architects. Without the need to redo the typical projects at their discretion should not.

Selection of material

From the gas silicate build, as already clear, a variety of types of houses, differing in area, scheme and floors. However, it is important to know which material is better to choose for a specific solution. To begin with, it is clearly distinguished by wall and partition structures. Use the wall block to arrange partitions can be, but it is expensive and difficult; The reverse replacement is unacceptable.

An important property is the density of the design – the higher it is, the stronger will be the design; True, the thermal qualities of products are deteriorated at the same time.

Additionally, take into account:

  • the presence of grooves and ridges;
  • linear dimensions;
  • brand manufacturer.


There are a large number of sites offering to calculate the need for gas-silicate or aerated concrete blocks. But not everything is so simple, as it seems. Sometimes you have to cut off excess material. And you need to strive to ensure that the number of these trimming is to minimize. However, even the most diligent builders usually lay down the flow rate of 3-5%; Beginners need to make a tolerance of 6-8%, as well as not forget about the counting of the mass of products.

It is necessary to be aware that calculations in online calculators are always an approximate nature. More accurate figures will be able to name only experienced builders. The correct final figure always turns out after subtraction of the opening area.

It is worth considering that the cellular material by definition absorbs moisture. Therefore, its volume and severity can change in fairly wide limits, the conclusion – will have to immediately lay the reserve.

Stages of construction


Since gas-silicate blocks are relatively easy, build a house based on them is the easiest way to use the pile foundation. The accuracy of the installation of all elements is evoked by the construction level. Since there are almost always needed special channels for communication, it is very difficult to do without strokesons. In advance you need to sow and take out all the trees (shrubs), to block the platform as much as possible.

The choice of the type of foundation and the specific scheme of its execution is determined:

  • the region where man lives;
  • the actual state of the soil;
  • land relief;
  • load magnitude;
  • The material capabilities of the owner.

The insulation of foundations for the most part is produced outside. If it is not done at all, frosty soil can even destroy the house. The usual options are the use of polystyrene foam or clay.

If it is decided to equip the slab base, it should be heat insulated at the construction stage. Do it in the process of exploitation is clearly late.


When building it yourself, it is also necessary to pay paramount attention. Special defense is needed outside, and inside the foundation (basement). In addition to using various materials, it will be necessary to use drainage water. Traditional and time-tested solution – Roll waterproofing. However, you can resort to masts, and to powders, and to the use of special films – ultimately all this is a matter of taste rather.

Main Series

Basic work technology does not differ fundamentally from manipulations with other block materials. The base should be prepared for work, it is maximally aligned, as far as the site allows. Approximately 30 mm of cement mortar lay on top of the waterproofing. Then in the course there is a hardening net. The first tier of the blocks always put out of the angle – it is easier to eliminate the appearance of errors.

Subsequent rows

For them are taken only after complete grasp of the first level. Usually you have to wait 2 hours (only specialists can say more).

Experts advise to use special glue for cellular concrete. The thickness of the adhesive layer is a read millimeters. Chasing an excess of the connecting composition inexpedient.

Reinforcement of walls

This procedure is usually carried out with each fourth round of blocks. But if the load is large enough, then it is necessary to strengthen the wall every three rows. Often limited to the layout of the steel mesh per solution. When using reinforcement rods, however, it is achieved where the best result.

Receptions under the rods should be knocked out the strokesis and partially fill in glue. The reinforcement itself on the interruption places lines are put.


Clearly construct jumpers – no less significant than statenly setting the design with decorative materials. Most often consumers choose already initially reinforced designs. A common error is to install “on the eye”; Experienced builders are definitely measured and counting in advance. Bearing jumpers are made as strong as possible, but nonsense enough to do and put so that they themselves do not disappear under the exertion. The loads themselves are calculated:

  • by a method of an equifiable triangle;
  • on the principle of the square;
  • According to the “1/3” method.


In any case, in a private house, it is worth insulating the floor – this will ensure optimal comfort. It should be remembered that the heat insulation of the gas silicate is carried out only after an additional drying, and not immediately after extracting from the factory package. For insulation, use polyurethane foam, mineral wool, claying and some other materials.

Overlapping themselves are usually performed by monolithic scheme. However, sometimes when the load is critical, the collection-monolithic solution is chosen.

Internal and external finish

Quite a lot of people trying, despite all the problems, plastering outside the facades from the gas silicate. For him, you need a vapor-permeable and resistant temperatures mixture. Pre-apply primer, boosting surface readiness for processing.

Fiberglass reinforcing mesh showed itself at least no worse than steel analogues. The grid needs to pull tightly, avoiding sagging.

Finishing decorative processing is carried out at least 48 hours after plastering.

Often outside try to separate the facade brick. But for this, initially the foundation should be wide enough to support them. Especially since additional air gap will need, excluding condensate education. If the installation of bricks goes close to blocks, then it is necessary to make a rather rigor between them. Otherwise mechanical deformations are likely due to the difference in expansion coefficients.

According to the aesthetic qualities, the best option is considered siding. It is best to see this material with vinyl-based siding. But you can apply metal structures (based on the same crate). Under the vinyl is preferred wooden frame.

But indoors are used:

  • lining;
  • plasterboard;
  • Plastic panels of various types.

Review reviews

Finally, it is worthwhile to give a brief release of the opinions of owners of gas-silicate dwellings. Reviews note:

  • strength and stability of structures;
  • the absence of usually repellent seams;
  • hygroscopicity of the material itself;
  • energy efficiency;
  • probability of severe precipitation without strengthening walls outside;
  • Attractive appearance even with minimal finish;
  • No discomfort (subject to construction standards).
