How to get rid of excessive humidity in the apartment? How to get rid of dampness in the apartment with affordable means

Since a dwelling with an overestimated moisture rate is not a favorable place for a person to live, it becomes more relevant how to remove humidity in an apartment.

The modern lifestyle of almost all people contributes to an increase in the level of humidity inside the room in which they live.

To understand this, it is enough to give a simple example: earlier people took a bath about once every 5-7 days.

Today, daily showering is the norm for the common man.

Some of the people play sports or go to the gym, as a result of which they constantly sweat.

In addition to the developed habit, take a shower every day or, you still have to wash clothes, and some even take care of pets.

The main sources of humidity in the room include:

  • human respiratory process
  • daily bathing procedures
  • laundry care, including drying, washing and ironing
  • influence of the external atmosphere
  • cooking in the kitchen

In any case, all these everyday moments cannot be avoided, so you will have to deal with excessive humidity in.

Possible effects of dampness

The most favorable place for the reproduction of microflora is a room with a high indicator of air humidity. It could be a bathroom or a basement. Humidity in a room often contributes to the appearance of a chronic disease in a person who lives here.

Most often, children suffer, because the child's body is not yet formed, and the immune system is not fully strengthened. Old people also suffer from living in such premises, since the protective and other functions of the body weaken with age.

Residents of houses that are made of brick most often complain about the problem of high humidity in the room. In turn, the inhabitants of the panel, complain about the lack of required level moisture inside. Dry air also negatively affects human health, as a result of which it can get sick.

If the room has a high level of humidity, you should immediately address the problem, since it is much cheaper to replace several household items than to spend financial resources for treatment.

In addition to the possible harm to human health, an increased level of humidity creates an uncomfortable state of being inside.

Often, due to an overestimated indicator of dampness, inside a dwelling or any other room, bad smell and feeling cool. In wet room food spoils quickly, including even vegetables and fruits.

In such rooms, mold and harmful microflora often form. Dampness is one of the most unpleasant phenomena that can spoil the whole comfort of living or being inside a building. If this problem is detected, it is worth immediately taking measures corresponding to the elimination of dampness.

Causes of dampness in the apartment

Before you begin the process of fixing the problem, it is worth identifying the main cause of the accumulation of damp air inside.

The main reasons for the accumulation of dampness inside the building include:

  • Lack of room ventilation. Even if ventilation is present, its performance and quality of operation should be checked.
  • Moisture may appear due to the heating of the apartment by neighbors from above. Often this problem is difficult to identify, since a neighbor who lives above an apartment with high humidity may not be aware of the breakdown of his plumbing. It is always necessary to check whether this is the main cause of orphanhood in the home.
  • If there are open seams between the walls in the building, moisture can also appear inside the building.
  • If the basement high-rise building flooded, then the moisture will rise up, as a result of which it will create dampness. Before you remove the moisture in the apartment on the first floor, you should make sure that the flooded basement is the main source of moisture.
  • Wrong location kitchen appliances may contribute to dampness.

To fix the problem, it is always necessary to find the source of dampness. The easiest way to identify advanced level moisture - lean a mirror or a piece of glass against the surface.

If after a few minutes water drops appear on the surface of the glass or mirror, then there is an increased level of dampness in a separate room or the whole room. If the glass turns out to be clean, you should not rejoice ahead of time, since moisture can be stored exclusively in the walls of the building.

How to get rid of moisture

As mentioned above, if a problem is detected, it should be immediately eliminated, since the influence of a humid environment can adversely affect the human body.

The most common methods for removing humidity in a room include:

  • Installation of an air dryer, which can be purchased at any supermarket electronic and household appliances. The price of a dehumidifier directly depends on its model and capacity. In any case, to fix the problem, you must purchase a similar unit. When buying, it is worth considering the fact that the higher the power rating of the device, the faster the dampness in a particular building will be eliminated. On the market for such products, devices with built-in dampness control sensors are offered. If the moisture indicator on the dehumidifier sensor drops, the device automatically changes the heating temperature. Thus, the device will not dry out the air, but will keep a stable rate of temperature and humidity inside the room or building. Note that such models use more electricity than standard, simple dehumidifiers that do not have a control sensor.
  • Mounting the radiator, if it is not. If there are radiators in the building, then it is worth using them. A damp room needs to be warmed up from time to time. When radiators emit heat, all of the unfavorable microflora, including fungi, may disappear, and the apartment will dry out well. Based on the advice of experts, the room should not be warmed up much, but often.

How to prevent excessive moisture

Houseplants absorb moisture. That is why it is worth acquiring plants, if there are none already. Flowers on the windowsill, in addition to their aesthetic function, perfectly absorb the dampness that is in the building.

Indoor flowers or other plants minimize any chance of increased moisture levels. For example, tropical plants absorb great amount water, therefore, putting such a plant in the bathroom or bedroom would be the right decision.

Cacti are the most "powerful" plants in terms of absorption capacity.

Unfortunately, due to the fact that these plants are not very decorative, many do not want to put them at home either.

When choosing a plant for a room, kitchen or bathroom, you should first study the characteristics of various plants.

If the above problem is identified, the main source of the emitted moisture should be urgently identified. And only after the discovery of the problem, the owner of the house should choose the ideal way for him personally to regulate the microclimate and, accordingly, reduce the level of moisture inside the building.

Increased humidity in the apartment slowly and gradually Negative influence on the health and well-being of a person, on the condition and decoration of rooms, on books and various products made of leather, wood, and clay. With excess humidity in the room, immunity weakens and lung function worsens.

As a result, a person often gets sick and catches a cold, suffers from chronic and skin diseases. These are various rashes, allergic reactions and eczema. Therefore, it is very important to deal with dampness and humidity in the apartment, if it is increased.

High humidity in the house provokes rapid reproduction fungus and pathogenic bacteria. As a result, mold forms on the walls and ceiling, dark spots, wallpaper peels off in the apartment and an unpleasant smell appears.

Moreover, the unpleasant smell of dampness and mold eats into the furniture for a long time, linens and even clothes. Fruits and vegetables, cereals and flour products cannot be stored in such a room for a long time, as the products deteriorate in a short time.

Most often too wet air found in brick houses, but this problem is also familiar to residents of panel high-rise buildings. Let's find out in more detail how to remove humidity in the apartment and get rid of the smell of dampness in the house.

Causes of high humidity in the house

  • Clogged hood or completely broken ventilation in the apartment. In this case, you need to contact management company. What to do if the hood does not work well at home, see;
  • The apartment is constantly heated;
  • Dampness in the apartment on the first floor may appear due to the flooded basement, from where the humidity rises into the house;
  • Unsealed seams between the walls in the apartment;
  • Water leakage in the house, which was incorrectly or untimely installed, or which cannot be determined due to closed water pipes;
  • Poor installation of kitchen appliances and blocking ventilation;
  • Regular drying of laundry at home in a large volume;
  • Constant humidity in the kitchen or in the bathroom can be observed due to improperly installed plumbing;
  • A large number of flowers create an overly humid indoor climate.

How to get rid of humidity and dampness

Before you get rid of dampness in the apartment, it is important to identify the cause of this phenomenon and eliminate it. Be sure to check the operation of ventilation and pipes for leaks, the quality of installation of kitchen appliances and plumbing fixtures.

In most cases, including a flooded basement, a non-working hood, and damaged batteries, you need to contact the housing office or the management company that controls your home. If the organization does not respond and does not correct the problem, you need to go to higher authorities.

A special dehumidifier will help you get rid of humidity and dampness in your house or apartment. When choosing, keep in mind that the more powerful the device, the more efficiently and quickly it can remove dampness in the house and remove unpleasant odors.

Experts advise using modern dehumidifiers with a humidity sensor in the apartment and changing the heating temperature depending on the percentage of moisture in the room. This eliminates the drying of the air and helps to avoid excessive consumption of electricity.

A damp apartment should be regularly heated with hot batteries and radiators. Devices dry the room and help fight mold, fungus and bacteria. But keep in mind that continuous heating should only be in the cold season, and sudden temperature changes are not welcome.

regular ventilation and Fresh air in room - better ways elimination of excess and high humidity in the house. Fully open every window in the apartment so that the air circulates in all rooms.

Be sure to leave the bathroom door open for at least two hours a day. Instead of ventilation, you can use an air conditioner that maintains the desired temperature and dries the air.

To eliminate dampness in a private house, if it comes from the street, you need to insulate the walls and ceiling. This will prevent moisture from entering the room, protect it from temperature extremes and condensation.

How to remove dampness in the bathroom and closet

Many are interested in how to get rid of dampness in the bathroom, because in this room the most high humidity. Periodically ventilate the room and try to keep the door open, be sure to check the operation of the hood.

To do this, bring a small piece of paper thin paper and bring it to the grate. The door must be open. It is desirable that the windows were open in the apartment.

If the paper is attracted, the ventilation works. If the sheet does not hold and falls, it has stopped working. In addition, the paper may fly off the grate, which indicates reverse thrust. In this case, not only does the unpleasant smell not leave the apartment, but an outsider also gets in.

Therefore, it is necessary to repair and establish the operation of the exhaust structure. Also, a heated towel rail will help to increase the level of dryness in the bathroom, with the help of which you need to periodically warm up the room.

Sometimes dampness appears in the closet, causing things to become damp. To solve the problem after washing, be sure to dry the clothes in washing machine or iron with a steam iron.

Folk remedies

To fix the problem, you can use folk remedies, which are distinguished by availability and cost-effectiveness. Arrange sugar, salt or coffee throughout the rooms, as they quickly absorb moisture. You can interestingly beat the interior, using coffee beans to decorate the room or any items.

Silica gel can be used for more than just cat litter. A universal remedy is used to store things and get rid of moisture. For this put universal remedy in bags and tie, put the products in a closet with linen or in a box with shoes.

Pour the product into a container and place under the sink or bathtub in the bathroom. But make sure that small children or pets do not accidentally eat the silica gel!

Use flowers that don't need to be watered often or that absorb moisture from the air. These are geraniums, ferns and cacti. In addition, essential oils will help improve the microclimate in the house.

tea tree, fir and coniferous extracts, grapefruit and lemon kill harmful bacteria, normalize the air condition and fill the apartment pleasant aroma. Therefore, oils are best suited if the apartment smells bad. In addition, ethers have a positive effect on the state and well-being of a person, improve sleep and mood.

How to prevent dampness

  • Clean with “draining” products, including vinegar, potassium permanganate and bleach. Wipe furniture and floors with solutions. If there is moisture, wipe the walls as well. At the end of cleaning, wipe the surfaces and remove excess water with a dry cloth;
  • Do not dry clothes and linen in the apartment every day. For drying, it is better to use a balcony, loggia or a special mode in the washing machine. If there are no such opportunities, dry things indoors no more than twice a week;
  • Misted windows accumulate water and increase humidity, especially in winter time. Rinse windows and mirrors regularly, and then wipe with a dry cloth or paper;
  • For regular ventilation, install special alpine vents that can be safely opened even in the cold season;
  • Instead of traditional plastic windows it is better to install wooden ones with double-glazed windows. wooden frames distinguished by environmental friendliness and naturalness, high breathability, because the tree “breathes”;
  • Before renovation in an apartment prone to increased dampness, treat the walls with antifungal agents;
  • When repairing, give preference to natural mineral-based building and finishing materials. They do not create a greenhouse effect and do not form condensate, regulate the level of humidity and absorb excess moisture. Avoid latex-based materials, as they accumulate even more moisture and have low permeability.

We looked at how to remove the smell of dampness in the apartment and eliminate excess moisture. However, many apartment owners suffer from the reverse problem when the air is too dry.

Insufficient humidity also causes a lot of trouble. In the house, dust and dirt accumulate in a short time, it becomes uncomfortable and uncomfortable, it is difficult to breathe and there is not enough fresh air.

High humidity in the apartment is serious problem. Over time, from high humidity, mold appears on walls, windows, furniture and even clothes. Not only do walls lose their appearance and things become unusable, dampness is also very harmful for human health. A long stay in a damp room over time leads to a decrease in immunity, exacerbation of allergic reactions and other health problems, including chronic and oncological ones.

Reasons for high humidity

There are many reasons for high humidity.

One of the reasons is the poor walls of the building from the foundation. This reason is connected with violations of technology during construction. As a result, the foundation transfers moisture to the walls, the walls evaporate it into the rooms. The result is high humidity in the apartment, and it doesn’t matter if the house is new or old. In this case, it is very difficult to eliminate the source of high humidity, because. such defects in construction are almost irreparable.

Other possible reason- salt. If the house is being built winter period, salt is often added to concrete so that frost does not interfere with the gaining strength of concrete. Walls in which there is concrete with salt will themselves be damp, and the wallpaper will be wet. And nothing can be done about it. But this is not scary, i.e. after a few years the walls will dry well and the dampness will disappear.


But most common cause high humidity in the apartment are problems natural ventilation. It often happens that in new apartment humidity was optimal, but after, for example, replacing windows with modern sealed ones, dampness appears. The reason for this is that airtight windows disrupt proper air circulation, and now moist air does not leave the room, condenses on walls, windows and provokes mold.

But even if everything is in order in the house with waterproofing and ventilation, this does not mean that the dampness problem will never arise. AT rainy summer when on the street long time costs high humidity, dampness may well pass into the rooms.

An aquarium can also be a source of high humidity. Aquariums, by the way, are recommended to be placed in rooms with low humidity, because they actively evaporate water and saturate the air with it. And if the humidity in the house is high, then the aquarium will only aggravate the situation.

Constant drying of washed laundry in rooms also exacerbates the situation with humidity.

The location of the windows of the apartment also affects the humidity. If the windows are sunny side, then the humidity is lower, if in the shade, then the humidity is higher.

- Heating is also one of the factors of humidity. If the heating in the apartment is poor, the batteries heat poorly, then this also contributes to an increase in humidity. - Leaking roof - if this is the case, then no methods of dealing with moisture will help until the roof is repaired.

There is another source of humidity that is inherent in any apartment - water is released into the air when people breathe. Moreover, we are not talking about milliliters per day, but about whole liters (from the whole family).


Ways to reduce humidity

To fight high humidity The apartment has several paths.

First of all, it is necessary to open windows more often and ventilate the rooms. This is true not only for getting rid of dampness, but also for maintaining health, because. fresh air is always helpful. If the heating is not central, i.e. a boiler is installed, it is useful to turn on the heating more strongly and open the windows. This method dries the rooms well.

Secondly, the ventilation system should be checked. It happens that the ventilation shaft becomes clogged, air exchange stops and humidity begins to rise. In this case, the shaft must be cleaned. It happens that the mine is poorly designed and there is almost no air exchange. In this case, forced ventilation can be built. Those. Install a fan in the duct.

Thirdly you can use a dehumidifier. An air dryer or dehumidifier is a device similar to appearance to an electric heater. The meaning of his work is that he sucks the air from the room, passes it through his filters, cleans and drains it. The output is air of the required degree of humidity, cleaned of dust. This option is the most expensive, but it saves even if other methods do not help.


By the way, even the most ordinary air conditioner, set to cooling mode, reduces the humidity of the air. This happens due to the fact that moist air, in contact with the cooled surface, condenses and is discharged through the tube outside the room.

How to measure humidity in an apartment

Increased humidity in the room can be determined not only by indirect signs, such as wet walls or mold on the wallpaper, but also with the help of a specialized control and measuring device called a hygrometer (the full name is "psychrometric hygrometer"). Household hygrometers are inexpensive. They can be hung in rooms and control the level of humidity. For reference: humidity levels from 40% to 60% are acceptable.

Any heated or cold warehouse has problems controlling the level of humidity in the air. The walls “flow”, the goods become damp, the wiring deteriorates, creating the prerequisites for the emergence of a fire hazard. Moreover, the condensate of water vapor "torments" the premises and stored inventory items both in winter and in summer. And than more area storage, the more noticeable these difficulties.

But how to lower the humidity in warehouse? And how to control the operation of "dryers" in a huge building?

Initial data

The company received an order dehumidify the air in a warehouse with a volume of 180 thousand cubic meters . Wherein ventilation system The room assumes a double air exchange with a mechanical induction of an extract and a natural inflow.

The internal temperature in the storage room must be maintained at 23 degrees Celsius (±1°C). The humidity level after drying should be no more than 40 percent, and ideally 30%.

The conditions are quite difficult - a large volume of the room, a high "internal" temperature and a fairly low percentage of humidity after drying. But it is possible to solve the problem of dehumidifying the air in a warehouse even in such difficult conditions.

How to reduce humidity in a warehouse - solutions to the problem

Firstly, to solve this problem, emergency intervention in the design of ventilation is necessary. An unorganized double-fold air inflow eliminates the very possibility of reducing humidity to 30-40%. Therefore, first of all, it is necessary to replace the natural inflow with a mechanical one.

Secondly, having arranged a mechanical inflow, you can proceed to control the temperature and humidity in the "incoming" stream. After all, warming up cold air, taken from the street in winter, we select most of the water vapor. Therefore, a fan coil or ducted air conditioner will have to be integrated into the supply branch, strengthening these units with an adsorption dryer.

Having solved the problem of winter drainage, it is necessary to take care of summer version when condensation of the vapors by heating the supply stream is no longer possible. In this case, we will have to cool the supply stream, heating up this medium later, before “pumping” into the warehouse. To do this, we need a pair of dual-circuit fan coil units operating for primary cooling (cooler temperature 8-9 ° C) and subsequent heating of the flow to a predetermined temperature of 22-24 degrees Celsius.

Fourthly, in the room itself it is necessary to install monoblock dehumidifiers with a capacity of 2000-3000 m3 / h, fixing them above problem areas at a height of 5-6 meters from the floor level. Moreover, these units should work only with "internal" air, drawing the dried medium directly from the room.

Fifth, to reduce the humidity level to the lower limit - 30% - you will need not only the above units, but also a decrease in the air exchange rate. In this case, the supply flow rate slows down and a series of fan coil units, air conditioners and adsorption dryers has time to “take away” the required amount of water vapor.

How to choose dehumidification equipment and how much does it cost?

To reduce the humidity in the warehouse, we need a dehumidifier - a unit that "collects" water vapor from the supply or "internal" air. That is, most of the estimate will form the cost of such an installation. Therefore, further in the text you will get acquainted with typical models of warehouse dehumidifiers.

According to the initial data, we need to dry a room with a volume of 18,000 m3 and primary humidity supply air 75-80 percent.

Based on these conditions, we can use the following dryer options:

Climate Aqua 400 by GlobalVent

dehumidifier Climate Aqua 400

Such an installation is built into the supply ventilation branch or mounted indoors. The Aqua climate dries the air by cooling the supply air to the dew point, followed by heating. Moreover, the evaporator grate is used for cooling, and the condenser grate is used for heating.

  • The performance of this model is up to 370 liters of fluid taken from the supply stream per day.
  • Power consumption - 6 kW.
  • Air exchange - up to 3600 m3 / hour.
  • The cost is about 600,000 rubles.

Mounted dehumidifier Dantherm CDP 125 drawing air from the room

Such an installation takes air from the room, dehumidifies the medium by cooling to the dew point and discharges the treated volume into the room.

  • The performance of this model is up to 7 liters of liquid per hour.
  • Air exchange - up to 2500 cubic meters per hour.
  • Power consumption - 3.2 kW.
  • Cost - 570,000 rubles

Adsorption dryer DanVex AD-1500

processing the inlet flow due to the absorption of water vapor by hygroscopic material, filled into the sinuses of the rotor. That is, the air passes through the rotor and loses most of the water vapor.

  • The performance of such a unit is up to 240 liters of moisture (condensate) per day.
  • Power consumption - 13 kW.
  • Air exchange - no more than 1550-1600 cubic meters per hour.
  • Installation - only on the supply branch of ventilation.
  • The cost is 950-1,000,000 rubles.

characteristics of the adsorption dryer DanVex AD-1500

Interior adsorption dryer MASTER DHA-250

processing the air taken from the room by absorbing water vapor with hygroscopic granules. The special feature of this particular model is high degree mobility of the unit - MASTER DHA-250 can be rearranged to a problematic place at any time.

  • The performance of the dehumidifier is 26.4 liters of condensate per day.
  • Power - 1.4 kW.
  • Air exchange - only 290 m3 / hour.
  • The cost is 162 thousand rubles.

As you can see: average cost channel dehumidifiers operating on a temperature difference fluctuates at around 550-600 thousand rubles. But such units are ready to "squeeze" out of the air up to 160-190 liters of condensate per day.

adsorption models industrial type cost about a million rubles. However, by adsorption from the air, you can "squeeze" up to 200-250 liters of condensate per day. So perfect results(final humidity of 30 percent or less) does not result in the use of one type of dehumidifier, but teamwork"temperature" and adsorption aggregates.

From this article you will learn about the main causes of dampness in an apartment or house. We will also talk about how to eliminate these causes and restore the normal microclimate of the home. You will learn about the traditional and most modern methods solution to the problem of air drying.

With the change of seasons, almost all owners are faced with increased humidity due to snowmelt. The spread of negative phenomena is great: from mild discomfort to “weeping” walls and mold. Consider some of the most popular cases and causes of dampness in residential premises, as well as ways to combat this unpleasant phenomenon.

Any changes in the microclimate have their own reason, influencing which, you can change it. Dampness has its own "sources", which the owner may not know about, or may not attach importance to them.

Reason #1: Poor ventilation

The owners often “forget” about the device of forced ventilation during repairs out of economy, relying entirely on windows and doors. In our apartments, the project provides for ventilation of two rooms - a bathroom and a kitchen. Living quarters have vents, windows and balconies for ventilation. Of course, ventilation lowers the temperature of the room by blowing out warm (and moist) air, so it is rarely resorted to during the cold period.

The effect of dehumidification in summer is achieved by mixing dry air from the street with vapor-saturated internal "exhaust" air. During transitional periods, especially in early spring, atmospheric air saturated with steam, but at the same time remains cold. Accordingly, ventilation does not bring the desired effect.

How to fight

Check the ventilation arranged according to the project - the draft should be noticeable. If the draft is good in the kitchen and bathroom, and dampness is not removed, there are three options for solving this problem.

1. Forced exhaust ventilation. The device of such a system, although it will entail certain costs and inconveniences, will solve the problem of dampness once and for all. The branched hood has its drawbacks - energy consumption, duct system, background noise. The minimum that can be done is to install a fan in the kitchen duct.

2. Installation of the heat exchanger. A ducted room heat exchanger of the "PRANA", "Reventa" or similar type is a more modern and ergonomic element that solves two problems at once - the extraction of moist air and the inflow of fresh air. Many models are heated for operation in the winter. The cost of a channel heat exchanger is from 340 to 380 USD. e.

Video: PRANA duct heat exchanger

3. Use a dehumidifier. This device passes air through itself, collecting excess moisture and filtering it. Such a device is very effective - it removes dampness from the room within an hour. At the same time, the composition of the air remains unchanged. Moisture is collected in a separate container and drained. Filters, ozonizers and fragrances can optionally be integrated into the device. The cost of such a device for a room of 30-50 square meters. m is from 140 to 220 c.u. e.

Reason number 2. Moisture source

In private houses, these are septic tanks or shambos located close to the house. They impregnate the soil with water, the water passes under the house, the soil surrounding the foundation or basement becomes damp. The same with atmospheric waters flowing onto a split blind area. Dampness in the basement and in the floor of the 1st floor is provided.

In apartments, this can be:

  • leaking roof;
  • a defect in the drain or overhang of the roof, directing atmospheric water to the wall of the apartment;
  • windy side of the house - rain constantly hits the wall of the apartment;
  • constantly flowing taps, plumbing;
  • a large number of water on the lower floor - aquariums, swimming pool, sauna;
  • evaporation of condensate on the windows (which collects due to poor ventilation).

It is difficult to name other trouble-free open sources of moisture in the apartment, but in each individual case everything is possible.

How to fight

Eliminate source. Fix a roof or drain, relocate a septic tank, protect a wall from atmospheric waters. If the reason is in an open source, waterproofing should be done with a liquid composition. Remember that waterproofing is applied from the source of moisture.

Reason number 3. Unheated room

Extreme savings on heating on the principle of "only warm air in the room "- the most common cause of dampness of the "weeping walls" of an apartment or house. The wall must be heated to at least half the thickness. Then the dew point (the place where condensation forms) will come out on the side of the street. A frozen wall shifts the dew point closer to a warm area, and sometimes even to the inner plane.

This problem often "works" coupled with a lack of ventilation. Abandoned or poorly heated premises become damp very quickly - Decoration Materials are destroyed in 2 seasons, the structure loses up to 5-6% of strength annually (in addition to natural wear and tear). It is highly undesirable to combine heated and unheated (according to the project) premises under one roof.

How to fight

Increase heating. Try to calculate how much damage your home can get from merciless dampness and the amount you save on heating. Then compare these amounts and draw a conclusion. Of course, insulation must be of high quality and timely.

If it is not possible to raise the temperature, set the fans to heating appliances and provide short-term ventilation - the humidity will even out. Do not leave the house unheated if you are going to return - find a person who will heat it.

Reason number 4. Improper insulation

Thermal insulation of walls with cheap and lightweight foam plastic or expensive modern extruded polystyrene foam has already gained momentum and is becoming a welcome event for residents apartment buildings. Almost no one ever makes a heat engineering calculation of the walls of an apartment to determine the thickness of the insulation. Therefore, when choosing a layer of insufficient thickness, the wall continues to freeze and dampen.

Life in such a "thermos" can spoil the dampness in the apartment and the inevitable fungus. The reason is the same dew point, which is comfortably located between the panel (wall) and the insulation plate. In addition, the vapor permeability of sounded materials is close to zero and this is not the only problem with foam. cheap material, produced in an artisanal way, is extremely flammable and toxic when heated. Keep this in mind when preparing to insulate the apartment.

How to fight

Study useful articles, where engineers and builders with extensive experience speak out. Understanding the physics of processes will save you not only from dampness, but also from many other troubles. There are two unmistakable options for warming an apartment:

  1. Obviously an excess layer of polystyrene insulation. A thickness of 100-150 mm guarantees that the dew point is outside the wall (in the thickness of the insulation) for any region.
  2. Vapor permeable insulation. Mineral wool, ecowool, any kind of ventilated facade. This is guaranteed to get rid of moisture in the walls.

Dampness in the apartment can provoke the appearance of mold, which, getting into the body, causes viral diseases person. In addition, in itself, humid air is not suitable for everyone. Weakness, soreness, spontaneous loss of working capacity - something that can happen due to excess moisture in the air. Therefore, the elimination of moisture is a concern not only for native walls, but also for yourself and dear people.
