It often happens that freezes through a corner in a brick house , an ice crust or frost forms on it. It runs vertically, horizontally or in all directions. This could be due to construction errors or a common physical phenomenon. Both options lead to the fact that the corner of the house is covered with moisture, which freezes at low temperatures outside. This can happen in a private brick house or in an apartment.
It doesn't really matter what material the house is built from.
Both panel and brick can cause trouble in the form of a freezing corner. The causes of the problem are almost the same. Nobody canceled the laws of physics and mistakes made during construction. All of them are listed in the table.
Table 1. The main reasons for corner freezing in the house:
|Reason for corner freezing||Description|
|Builders' miscalculations|| Incorrect dressing of masonry, not enough cement mortar was used.
There are voids, gaps through which cold and moisture penetrate.
The brick is not laid out correctly or is not enough for the specific climate. Should be stacked not in 1, but in two layers. Because of this, the thickness of the wall is insignificant, which leads to freezing of its corner.
|Cold bridges|| Cold bridges are understood as those areas of the house that should initially be insulated.
All corner parts belong to them. Builders are required to insulate them, use special insulation. If there is none, then there will certainly be frost, condensation.
|Foundation||Insufficient basement layer, its subsidence, erosion by groundwater.|
|Physical phenomenon|| Due to the small wall thickness, improper brick binding, moisture is formed, which is condensation.
Over time, when temperatures are low outside, the liquid freezes. The condensate itself is formed as a result of a physical phenomenon. The temperature inside the house is higher than in the cold outside. Due to the drop, moisture occurs.
In a panel house, the reasons for the appearance of frost in the corners are similar.
True, there are much fewer of them. Usually mistakes are made during construction:
Still, this problem most often occurs in buildings built of bricks.
The reason lies in the material itself. Builders use low-quality bricks with chips, voids, through holes. If it is also laid out with a small amount of solution, there is no facade decor, insulation, then the problem cannot be avoided.
This is important! Do not forget that a corner in a brick house is laid out using a special technology. The correct dressing of the masonry must be performed. If the technology was not followed, then the corner will freeze through.
Sometimes the problem area is observed not along the entire length of the wall, but in its separate part, for example, near the ceiling (roof). The corner just below the ceiling is covered with moisture or ice. Here, the reason lies elsewhere. Work was carried out incorrectly to adjoin the wall to the very ceiling of the roof. There are cold points between them.
It is possible that insulation is not used at all in the attic, and cold air comes from there.
Some brick houses sag over time, cracks form on the walls , emptiness. There is a sharp temperature drop at the inlet and outlet, the same condensate is formed. Due to the presence of cracks, gaps, it quickly cools in the corners.
Interesting to know! The frozen part of the wall is just the "tip of the iceberg". Over time, not only moisture will form in the corner, but also mold.
This is an inevitable consequence of the problem never being resolved.
It should be understood that such a situation can occur not only in a private house, but also in a multi-storey one. Even apartment residents complain about wet or frozen corners.
A brick house differs from a panel house in the materials used in construction. Many people think that it is much more environmentally friendly and warmer, but that was not the case. It all depends on the quality of the brick, and the work itself on laying it.
Even in a brick house with thick walls, corners can freeze.
Even if a brick house was built quite recently, it is impossible to exclude the appearance of cold, moisture in its corners. The builders could lay out the brick incorrectly, they used it in insufficient quantities. The influence of the climate should not be canceled either. If the region experiences low temperatures, then laying in one layer will clearly be insufficient. Then the corners will be the most vulnerable area.
Emergency brick buildings, houses with a high percentage wear is a sector where problems always arise, including with corners.
They freeze because of voids, cracks, cracks, and because of the cold coming from the roof. Here, the situation cannot be resolved by insulation alone. First, work is carried out to eliminate the same cracks or other defects.
Residents of panel houses, even in their apartments, can observe frozen corners, the accumulation of moisture on them. You shouldn't blame bad building material. It is unlikely that panels with cracks, voids and other defects were used.
This happens very rarely.
The reason lies elsewhere:
It is warm inside an apartment in a panel house, but not outside. Since the corners are the most vulnerable points, then condensation forms there. Moisture simply freezes over time.
Cold air blows in exactly at this point or from the roof. If it is not insulated enough, then problems can also be avoided.
The same happens when the neighbors don't keep an eye on the plumbing and pipes. They leak a little, which causes water to form in the upper corner of the apartment located above.
Sometimes the construction technology is not followed. There are voids, large gaps in the wall, through which a cool wind blows. Even in a panel house, builders' mistakes cannot be ruled out.
Sealant, insulation, putty, thermal insulation - what the owners of apartments and houses do not use to get rid of the problem with a freezing corner.
Even having reached the very wall from the inside, it is not enough to close up its cracks. Internal insulation won't help either. All this helps very rarely, when the corner freezes just a little.
This is important! The overwhelming majority of experts recommend insulating a house or apartment outside, not inside. Then you can solve the problem completely, eliminate its causes.
Internal insulation and other work will only have a temporary effect.
Of course, you can try to insulate the dwelling from the inside, but, as a rule, this does not help, but only increases the amount of costs. All the same, you have to do all the work outside, since this is the only way to eliminate the root cause.
When the corner of the wall is covered with moisture, ice or a layer of frost in a brick house, then the situation must be solved radically. First, you should diagnose. Its main stages:
It is she who is the source of the problem, you should not look for the cause inside the home. You should pay attention to the presence of cracks, voids, the quality of the brick and the masonry itself.
If the brick house is worn out or in emergency, then you cannot do without metal ties.
There may not be enough solution between them. The building material itself, if it is of poor quality, can have many gaps, pores or cracks. Such a brick causes the corner to freeze.
After diagnosing and determining the cause, you should draw up a scope of work, determine how best to solve the problem. As a rule, insulation is used outside.
Experts do not recommend doing internal work.
The only correct solution to get rid of frozen corners in the house is to insulate it. Only thanks to him, moisture or frost inside will go away once and for all. Do not forget that before insulation it is necessary to examine the wall for cracks and eliminate them in advance. The following solutions are suitable for this:
These are time consuming and costly work.
As a rule, further insulation is required. This method is used most often, and is recommended by specialists.
If freezes a corner into the house e , the following guide will help:
As a rule, such plaster contains expanded polystyrene granules. It expands and fills in empty pores.
It all depends on what kind of exterior finish (siding) will be chosen.
There are many materials that have an aesthetic appearance.
The apartment can be located in a building with different number of storeys. Sometimes insulation is required at a high altitude. Then you need to contact the specialists working with equipment for climbers. An open exit to the roof of the house will be required, since this is how the equipment is attached, the ropes with slings go down. The work of such specialists is dangerous and expensive.
When the apartment is located on the 1-2 floor, scaffolding is often used.
This is important! It is impossible to insulate only a part of the wall, for example, only its corner. Then the problem will accidentally arise in a completely different place: where there is no insulation. Complex work should be carried out.
The most correct step would be to insulate the outer wall, since interior work is unlikely to help.
The dew point will simply shift, and condensation in the corner will form with even greater intensity. Sealants, internal insulation are just waste of money . Over time, it turns out that it was still necessary to carry out external work.
Is external thermal insulation always necessary? There are situations when the outer corner in the apartment freezes over due to uncharacteristic reasons. This includes flooding, water leakage from neighbors. It is the upper corners that suffer from this.
Then you need to contact the apartment owners from the top floor. Even if there is no constant flow of water, then its leakage can occur almost imperceptibly: from a pipe, battery, etc.
The apartments on the top floor have another problem. At the junction with the roof, the builders could have made a mistake. They did not install insulation, or there are gaps, cracks, voids between the floors and the wall.
Then the reason should be looked for there, and not in problems with the angle or condition of the wall.
Additional thermal insulation of floors, other work in the attic will be required. Perhaps the roof has fallen into disrepair, and it is from it that the water comes. It often concentrates precisely in the corners. In all other cases, only external insulation of the walls of the apartment can be salvation.
As soon as defects the brick wall has been removed, you should proceed to its external decoration.
It will thus serve as insulation and a solution to the problem with a freezing corner for many years. The same applies to panel houses. They are also insulated, no matter what floor the apartment is on, although the choice of materials is limited here.
Not every siding is suitable for a panel or multi-storey building, since the finishing material must fit into the architecture of the house and not disturb it. The entire list of heaters is given in the table.
Table 2. Types of heaters for exterior decoration of the house:
|Thermal insulating plaster||More often used for exterior decoration. It has a high vapor permeability, so condensation will not form inside the house. Contains particles of expanded polystyrene, not sand.|
|Liquid thermal insulation|| Compositions on an acrylic basis, which are identical in properties to mineral wool insulation.
It is applied in 1 or 2 layers. Antifungal components can also be included in such a liquid insulation. Thanks to them, mold will not form in the corners. The composition is quickly applied. Adheres well to almost any surface.
|Thermal panels|| This includes siding, sandwich panels. The latter are finished in the form of decorative bricks, imitation of the texture of natural stone and other options. Thermal panels are applied directly to the outer wall. Sometimes a frame is pre-assembled from profiles. The material is easy to cut and quickly attaches to the surface.
No additional training required.
|Mineral wool||The classic method of insulation, which is gradually becoming a thing of the past. There are a lot of ways of such finishing. For example, first the mineral wool itself is laid along the wall, then corrugated board or siding is attached on top.|
The usual foam plastic is also used, on top of which a layer of plaster is applied.
This is a cheap way of insulation, used not only in brick, but also panel houses. In the latter, it is used much more often, since it allows not to disturb the general appearance of the house. Different thicknesses of foam are used, on which the degree of insulation depends. When performing work, it is important to eliminate gaps between the joints. Otherwise, cold air will pass through them.
Thermal insulation materials
You should not look for the reason in the faults of the walls from the inside.
Sealants, interior decoration will not help, but will only exacerbate the problem. The dew point will shift towards housing, condensation will form even more intensively. In the cold season, the corner will not only freeze through, but also be covered with frost and ice crust.
For a private house it is necessary:
Reconstruction work may be required;
For apartments in a panel building, the cause of the corner freezing should be determined.If it does not lie in flooding or overlappings on the roof, then an insulation gasket will also be needed. It is carried out outside, not inside. There are not so many insulation options for a panel house, since it is important not to disturb the appearance of the building.
If the apartment is located in a brick building, then the choice of materials is significant. This includes thermal panels, thermal insulation plaster, liquid thermal insulation, mineral or basalt wool, and other types of siding. They are also suitable for private households.
Calling a specialist is often not required if the cause of freezing in the corners is established. As a rule, he recommends insulating the wall from the outside, not from the inside.
Internal work is not shown in almost all cases. As for the choice of the material itself, it is not worth saving on it. It all depends on the extent of the problem. When the corner freezes slightly, it is not necessary to use expensive thermal panels.
