Plastic windows - a brilliant invention of the second half of the XX century. They are beautiful, neat, sealed, practically not requiring care, beautifully insulating the apartment. Their advantages can be listed in no one hour.

But they were invented by German engineers from hopelessness, since after the Great Patriotic War, huge resources were required to restore defeated and crushed Germany. Forests, for the manufacture of windows - almost no, or it was very expensive. To replace it, plastic windows were invented, which were several times more expensive wooden. The essence of their invention was reduced to the fact that only one frame was required to preserve heat in the apartments, and this made the product much cheaper. As a result, it turned out that the plastic single-chamber glass was completely replaced by two-frame wooden windows without any heat loss.

But despite all the wonderful qualities of metal-plastic windows, they are not devoid of flaws. And the shortcomings are so serious that they question the need to use them. So it is or not, let's understand together.

Svetopropusage - the problem of plastic windows

To date, most people start repairs in their home with the replacement of old wooden windows, new, metal-plastic. But that is that most people who have established these modern products have noticed: although the glass windows visually takes 90% of the entire area, the lights in the apartments have become less. But if you calculate, it turns out that the area of \u200b\u200bglazing such windows is approximately 20% less than wooden. And this is not the most important problem.

What happens in an apartment with good windows, but without good ventilation

Let's go deep into the theory. The principle of operation of ventilation in our homes is natural, which means that polluted and spent air leaves and in the bathroom. Fresh air comes into our apartments through natural looser in the windows. In our old, not always beautiful, wooden windows were different gaps. We fought with them, but they won us, regularly forcing them to stick off paper strips. But it is thanks to them, our ventilation system worked as a clock: one air went out, giving way to clean and fresh.

What happens with ventilation after installing PVC windows? And nothing, you can not talk about what is not. Ventilation does not work in the apartment, and again it is not the worst thing, in fact terrible appears a little later. After a short time, an increased humidity appears in the dwelling, which is an ideal place to reproduce microorganisms, not only "good and good". Together with bacteria in a wet warm room, mushrooms appear.

Do not think that at the corners of your dwelling will begin to appear champignons to appear. Your dwelling turns into a real mushroom plantation, but these mushrooms are "small killers" living on the walls and ceiling, capable of dumping a healthy person with a severe form of asthma or allergies. Air circulation in such an apartment is disrupted and this leads to a sharp decrease in oxygen content in it and an increase in the level of toxic substances.

The second scenario for the development of events.

Suppose that the ventilation system in the apartment, after installing PVC windows and hermetic doors with a good seal, works. But since there is no air inflow, then only the natural extractor is in the work, which is located in the toilet and in the kitchen. The extractor works properly and pumps the air out of the room, but the vacuum will not work anyway, since one of the two exhaust systems simply turn into the supply. What threatens it? And practically nothing but the appearance of remarkable flavors from neighboring kitchens or toilets in the apartment, from the system of which will turn out air.

http://www.youtube.com/watch?v\u003dvdbxkfemhtm And all this due to the lack of air-turn, the cause of which excellent sealed plastic windows have become. Do not think, we no way we offer to abandon the really good PVC windows, besides, thanks to their production, the forest is preserved, and it is known - this is light planets. We told these horror stories so that you understand that the replacement of its wooden windows on PVC products needs to be approached comprehensively, i.e. Immediately take measures to establish ventilation in the conditions of tightness of the room.

How to make ventilation in a hermetic apartment

To implement this project there are several options: restore the natural influx of air or organize forced ventilation in your home. But this type of ventilation system is a fairly costly event. It is much easier, faster and much cheaper to organize natural ventilation of the room with one of the ways we suggested.

1. To ventilate the apartment.
2. Install on your windows from PVC microwing system.
3. Organize air circulation by installation.
4. Install in the apartment compact supply ventilation.

Housing ventilation Very good and not quite an effective habit for restoring air circulation indoors. It is good because when ventilating the room, oxygen falls, and the influx of air masses is created. But why not quite effective? Together with oxygen in the apartment falls: exhaust gases, production products, dust, from which not all good air filters cope, street noise. And this is all with good weather conditions. The ventilation is perfect as a short-term measure to increase the air-turn, and for hardening the body. And this is an excellent method of complacency: "After all, I ventilate the room, it means that I do something to improve the microclimate in the housing and your health!" Microwing systems Microwing is or fixtures that will insert a weak air flow from the street. Due to the variety of such devices, you can easily, and most importantly, without special financial costs, organize "natural gaps" in window openings. Such devices are still good in that most of them can be installed on their own, nor resorting to help professionals. Some types of devices, still have to be installed without the help of manufacturers of window systems. There are more serious devices that are automatically, when changing the indicators of humidity or temperature inside the apartment, or open, by providing air to the air freely enter the room, or close, completely overlapping the access of air to the dwelling. Microwing system will provide a sufficient influx of fresh air. Your home will remove excess moisture out of the room and create a good microclimate in your apartment. Installation in the apartment of the supply wall valves Wonderful and inexpensive "tool" to create air inflows. A hole of a certain diameter is drilled in the wall, and the trim valve is "implanted".

• It looks like a plastic tube cut, with a diameter of 5-6 cm.
• The principle of his action is that the air through it freely enters the room, and it can not go back. The valve provides air flow adjustment, filtering from mechanical impurities.
• When installing it for heating devices, i.e. for the battery, the trim air will also be heated. Nothing is difficult and dear in it, but there is a benefit, and what else.

The only "but", they may need to be somewhat to create a sufficient number of air flow. Installation of compact supply ventilation
This is one of the most modern and civilized options for creating a ventilation system in your apartment. It relates more to forced ventilation, but we could not but affect this topic, because of her crazy popularity. Compact supply ventilation in the apartment is both an influx and an air hood in a "one bottle". Moreover, the ventilation is not easy, and with the filtration system and heating the incoming air without additional energy consumption. How does it work? This unit, externally similar to a small, pretty cute drawer, which is hanging on the wall, there are two fans, air filter, recuperator, and a control unit to all this "economy". A very convenient device that costs some money on its purchase and installation. Even with a fully disabling ventilation system in your apartment, this device is capable of implementing it. In fairness it is worth noting that there are some more options for solving the problems of the ventilation system, such as the installation of a separate ventilation with a recuperator or a monoblock system, which automatically sends the ventilation system into the dwelling system and the air conditioning system. But we did not deepen into such difficulties, as these systems require a serious engineering approach, calculations, projects and a lot of money. The purpose of this article is to show the importance of a comprehensive approach to solving some tasks, namely: the installation of plastic windows requires an immediate solution

The constructive solution of household ventilation does not imply humidification functions. The air is served the air of the same humidity that outside. In a situation where in the room is increased humidity, and on the street dry, the air conditioner will help to align the climatic conditions. If the same airflow is too dry, then we recommend using a moisturizer.

Controller, air purifier, humidifier and air conditioning - What is the principal difference?

How often do you need to turn on the ventilator?

The device should work in the round-the-clock mode - people do not matter in the room or not. Human breathing is accompanied by carbon dioxide release - comfortable conditions for people located in the room in the room are formed by a constant influx of fresh air. Allergens, unpleasant odors, harmful substances are all allocated to furniture and pets even at a time when there is no one in the room. The inclised ventilator will ensure air freshness in any time you do not return home. It is recommended to turn off it only if a long absence is assumed.

Are household ventullation in a house with a warmed facade?

Definitely yes. But, this factor first need to warn the assembly brigade. This will allow specialists to maximally correctly install the device correctly by performing a through hole under the air duct in the wall structure, including the venerable ventilation tile of the ventfassada.

What coordination is needed before installing the ventilator?

No permissions to get the need. Actual building rates say that the performance of the holes with a diameter of less than 200 mm is not coordinated with the competent authorities. From the street they are protected by a decorative lattice and the presentability of the appearance of the facade does not suffer. What can not be said about the external air conditioner unit.

I have Ventfasad: how to install household air ventilation?

There are 2 ways to install the system, each of which has its own nuances and specificity. In short, they can be described like this:

The hole is performed not through, and it reaches only before the veneer plate of the ventfassada without perforation of the heat insulating layer. In this case, the air is closed from the gap between the insulation and the final facade finish. The magnitude of the gap is 40 to 100 mm.

Air fence is carried out directly from the street. In this case, the hole is clogged through all the structural layers of the wall. That is, thermal insulation, external facade trim from the tile, for example, a porcelain tile. Please note that if the work must be performed at the height, then an industrial climber is attracted to perform a hole for the air duct for the duct of household supply ventilation.

How much does the air ventilation noise?

The design of the device involves six operating speeds:

• The 1st is characterized by a maximum sound pressure level of 19 dBA, which is significantly lower than the natural sound background of the environment in the range of 25 to 30 dBA;
• 2nd, 3rd and 4th speed is noise compared to the work of the household air conditioner;
• The 5th and 6th speed are recommended with active air ventilation.

Is there noise from the hole in the wall under the conductor?

To maintain good human health, a constant influx of fresh air is needed. From the lack of air exchange, well-being deteriorates, efficiency falls, the mood is reduced, the prerequisites for the development of various diseases appear. Regular ventilation must be performed for any room. Good ventilation in the apartment with plastic windows is especially important.

Ventilation of premises as a vital necessity

Ventilation, or ventilation, must be carried out to replace the exhaust air to fresh to maintain the oxygen level in sufficient human activity for normal life.

We spend about 70 percent of all life in a closed space, so it is important that the air that we breathe is that work, public places or your own apartment - contained as few dust and pathogenic microorganisms as possible.

If you take a standard apartment or the House of the Russian resident, then you can say with solid confidence that in most of them the air condition does not meet sanitary and hygienic standards to ensure healthy breathing and comfortable life.

The causes of this are:

• Air humidity due to evaporation in the bathroom and kitchen;
• Human-separated carbon dioxide in the process of human activity;
• For kitchens equipped with gas stoves - highlighting harmful products when burning natural gas;
• Harmful allocations from the objects of the situation and the materials of the finishing of the premises;
• Dust formation.

Increased humidity, accumulation of dust, among other things, contribute to the development of mold and reproduction of bacteria dangerous for the human body, fungi.

All these factors create a cumulatively unfavorable atmosphere for human health, where he spends most of his life. Hence the frequent diseases of the respiratory organs and other ailments, about the true cause of which few people think.

Wooden windows do not need ventilation

Apartments with windows in wooden frames are provided with fresh air flows from the outside due to breathing material and numerous microcenes. Ventilation in the apartment with plastic windows is noticeably difficult, because thanks to hermetic fiberglass packages, the air through closed windows does not come at all.

Therefore, it is very important to provide apartments and residential houses by constant ventilation, which will allow to carry out timely exchange of polluted air to clean.

Types and principles of ventilation apartments

Ventilation on the principle of implementation is divided into two types:

• Natural;
• Forced.

Natural ventilation is carried out through all the possible "gaps" in the apartment due to the pressure difference between the residential premises and the street. Heated wet air from the dwelling dwelling is outward, and in return, a colder clean thread is absorbed. However, this type of ventilation does not always fully ensure the needs of a person, especially in a warm period of time.

Forceding is carried out thanks to the mechanical exhaust of dirty air from the apartment with simultaneous injection of fresh flow from the outside. For the implementation of this process requires a trim and exhaust channels.

Forced ventilation systems are built by one of the three types of mechanical ventilation:

• Trimmed;
• Exhaust;
• Supply-exhaust.

Advantages and features of the supply system of ventilation

The trim type is the simplest. It can be carried out in a natural way using the ventilation channels for this. A good inflow of fresh air is carried out through an open window or a window. However, this method is little acceptable in the autumn-winter period, when heat leakage from the apartment occurs together with ventilating.

Therefore, the installation of the supply valve will help you to ensure the air exchange. It is installed under the window above the heating radiator, thanks to which the cold stream coming from the street heats away from the battery.

So that the natural ventilation of the supply type has been full, you need to install the supply valves in each room of the residential room. The performance of one supply valve is a complete substitution of about 35 - 40 m3 air per hour of work. For normal vital activity of one person, 30 m3 / hour is required.

Supply ventilation in the apartment is often combined with air conditioning, to create a favorable microclimate indoor.

For mechanical support for supply ventilation, individual or channel supply installations will be required.

An individual inlet system can be installed in two or three hours with their own hands. This does not require installation of the ventilation channel system. However, it, with a large electricity consumption, is able to fully provide fresh air only one room. Therefore, such ventilation in the house or apartment is extremely rare.

Forced ventilation using air channels provides a large amount of work using special equipment. Channels are mounted over the ceiling using inter-storage space to provide air intake in all rooms. This requires large investments of time and material costs. The monoblock, with the help of which the exhaust and the extraction of fresh air used for the standard apartment is provided, must have a power of about 300-500 m3 / hour.

Video on the topic: Simple supply ventilation for the apartment with your own hands

Exhaust ventilation system

Each apartment building has a stationary exhaust ventilation system consisting of central ventkane and air ducts, supplied to each apartment.

If you have noticed that you have a long scent after cooking, or "flavors" from the bathroom and toilet rooms, this is a testimony of insufficient or completely absent ventilation. Very often, such a phenomenon is observed after replacing ordinary wooden frames on plastic glass windows.

You can check the functioning of the built-in ventilation system in a simple way: it is sufficient to bring 5x15 cm paper strips to the ventilation lattice and trace it for its condition:

• If the paper remains fixed, it means that the ventilation system does not work. Open all windows and bring up the paper to the ventilation grille.
• If the paper with open windows sticks to the lattice - the channels operate, and the problem in the receipt of fresh air. Especially often it happens in apartments with plastic windows, where natural ventilation is hurt.
• When, even when the windows are open, the paper does not stick to the lattice or barely stirring, it is necessary to clean the air channels. Because of the accurate dust or dirt, garbage falling, insects the air movement is difficult.

IMPORTANT: In no case, do not try to test the operation of Ventkanal using an open flame of a candle or matches! This can lead to a fire accumulated in the heavenly gas channels!

Local vents are installed in the kitchen and bathroom. Given the special contamination and humidifier, it is possible to strengthen the operation of the ventilation system here using the exhaust fan.

Kitchens in the cooking zone need to be equipped with an extract. Its use allows you to prevent the spread of kitchen smells and evaporation for all residential premises.

To ensure ventilation in the bathroom, it is recommended to use an electric built-in fan. Given the increased humidity of the air, it should have reliable protection against water. This level fans have an IPX4 label. The exhaust fans also presented the requirements for silent operation and productive power from 50 and above air of air per hour.

Advantages of forced ventilation

The widespread passion for plastic windows is due to the desire of people to reduce heat exchange during the cold season and the maximum conservation of heat. However, this also leads to the difficulty of natural air exchange due to the tightness of windows with fiberglass packages. At the same time, life products accumulate in apartments - carbon dioxide and excess moisture. If we consider that every person allocates approximately 20 liters for an hour. Carbon dioxide, then in the absence of forced ventilation in an apartment with plastic windows, the concentration of harmful substances in the air exceeds all permissible sanitary and hygienic standards.

To ensure comfortable, safe for the life of the apartment in the situation, air exchange indicators should be no less than those shown.

According to paragraph 31-01-2003 "Buildings of residential apartment buildings", the rate of air exchange is:

• For residential rooms at the rate of up to 20 m2 of a total area per person - no less than 3 m3 / h for each meter of living space;
• 30 cubic meters of air per person per hour if each account for more than 20 m3 of the total area;
• For premises using gas equipment (gas stoves, boilers) - 100 cubic meters of air per hour;
• For a kitchen with an electric stove - at least 60 m3 / h;
• For bathtub, toilet or combined bathroom - 25 m3 / h.

List of advantages

Provide regulatory requirements for the provision of residential premises with the influx of fresh air can be used only by applying forced ventilation.

The benefits are obvious:

• Forced ventilation does not depend on the time of year or weather;
• Does not need complex engineering calculations when laying communications;
• It allows you to ensure the influx of the required air volume into all residential rooms and exhaust of rooms with high humidity, gas and lack of natural ventilation (kitchen, bathroom, storeroom, wardrobe, utility rooms);
• Promotes the mixing of indoor indoor air with incoming dry, thus reducing the possibility of condensate formation.

Many apartment owners, where the usual wooden frames were replaced with fiberglass packages, complain. This is due to the occurrence of the so-called "point of the dew" - when the surface temperature of the walls and windows is lowered to the condensate necessary for the formation of condensation at a certain humidity. The higher the humidity of the air, the higher the temperature of the "dew point".

So, if the air temperature inside is +18 degrees Celsius, and the humidity is 50%, the dew point is 6.8. As an increase in humidity up to 75%, this indicator increases to 13.2. That is, with an increase in air humidity indoors, the ambient temperature is favorable for the formation of condensate.

It is possible to avoid a similar phenomenon for an apartment equipped with plastic windows by ensuring the forced ventilation of the supply-exhaust type.

The purpose of the invention of plastic windows is to provide consumers the opportunity instead of two frames use one, making glazing cheaper. Plastic hermetic, attractive, not demanding in care. But any medal has two sides. After removing the tree, additional ventilation in the apartment with plastic windows is required. Otherwise, building structures and furniture will spoil condensate. Air conditioning or air purifier problem is not able to solve.

What happens in an apartment with plastic double-glazed windows

Most apartments of our country are ventilated naturally. Air inflows provide looseness in frames and door boxes. The spent air flow is removed through the ventilation holes in the kitchens, bathrooms, bathrooms. It is enough if wooden sash in the home is not broken by the integrity of the channels.

After installing PVC-windows, even with well-running ventilation, changes are inevitable. After stopping the air inflow, the channel in the kitchen or the exhaust bathroom turns into a difty. The rooms fill the unpleasant odors from the neighbors, the humidity increases, which contributes to the reproduction of bacteria and the formation of fungus.

Housing owners are forced to ensure the influx of fresh air or organize other ventilation systems.

What functions perform ventilation in an apartment with plastic windows

In rooms with wooden structures To improve ventilation efficiency, you can install fans in exhaust channels. In winter, they did not even need to be included thanks to temperature difference.

The installation of plastic windows radically changes the situation. Air in the home eventually can become more toxic than on the street.

Of the simple solutions at the tenants there are four:

• regular ventilation;
• installation of electric fan in mines;
• installation of micro-level devices;
• installation of supply valves;
• installing compact fans.

Plus the ventilation - entering the oxygen room. But in the city it is complemented by dust, noise, exhaust gases. This means that this method is short-term and ineffective.

Electric fan are suitable for kitchens and bathrooms. They are installed in reset mines, are turned on manually or automatically (with increasing humidity or reduction of air quality). These devices offer many manufacturers at different prices.

Microwing is called the depressurization of plastic by mounting to it adapts, inflowing air from the street. In fact, it is the organization of gaps and installed devices in them, the cost of which depends on the manufacturer and configuration.

The supply valves can be installed in the outer wall, in the junction between the window and the wall, in the profile, under the window board. These are plastic pipes through which the air flow from the street moves. The market offers models with different bandwidth, which is adjusted manually or automatically. To calculate the number and location of the valves, it is better to attract a specialist. To increase the efficiency of the supply installation, you need a fan in the mine.

Another option is an exhaust fan that throws out the spent air flow. It is suitable for the kitchen and can work constantly or as needed. Check valve blocks the path of the airflow from the street. Dear models are equipped with sensors including a fan at a certain level of pollution. For bathrooms and bathrooms there are moisture-proof models for mounting into the outer walls.

Parameters and composition of forced ventilation

The optimal option is split system for the entire apartment on the balcony, in the storage room, in the hallway. When installing, it is necessary to take into account the need for maintenance and repair. You can arrange the design in the wall, a tail ceiling, on the floor. The air flow from the street serves a collector connected to the rooms of the air ducts mounted in the suspended ceiling. The spent stream is removed from the bathroom, bathroom or kitchen. After connecting to the power grid, such forced ventilation in the apartment with plastic windows works automatically all year round.

Before developing the project, dew and air exchange point is calculated in accordance with the requirements of SNiP. If the project is developed correctly restores a balance that does not allow for condensate.

The system may consist of:

• instruments for forced tributary and natural hood;
• instruments for forced inflows and exhaust electric fan;
• supply and exhaust device with a recuperator;
• supply valves and.

The equipment is selected, based on the characteristics of a particular apartment, preferences and financial capabilities of the customer. First calculates the dew point and air exchange in each room. Then the devices are selected (supply valves with cleaning and heating, electrical fans) and the duct layout project is developed.

Such a system is simply configured, fully ensures the required parameters of air, it practically does not depend on external factors.

Do I need to additionally ventilate a frame house

The tightness indicators in the frame house are high, if it is built using modern technologies. Natural ventilation functions well only in winter, but reduces the temperature in the premises. With permanent accommodation requires a compulsory system. According to the design, it does not differ from those that are mounted in apartments.

The type of system depends on the area and features of the house. The most economical option is a natural influx and forced withdrawal. But such ventilation lowers the room temperature. Therefore, it is better to establish an expensive design that supports the set temperature and humidity parameters.

All of the above does not apply to the house or the dacha, in which they live periodically. In summer, ventilation is ensured by ventilating.

Plastic glazing is a fairly convenient and practical invention of the modern building industry.

Properly organized ventilation system involves the presence of air flow and its exhaust. To ensure comfort in the house, you need both of these components. During operation, we made sure that ventilation in the apartment with plastic windows has certain features that affect the general atmosphere indoors. Ventilation in plastic windows will help to normalize and make an apartments favorable microclimate.

The effect of plastic windows on the ventilation system

The familiar practice of designing apartments provides a peculiar ventilation system that implies the presence of an exhaust in the kitchen room, the bathroom, and it goes without saying, the air ventilation by opening windows and doors.

Installing PVC windows in the root changes the ventilation system in the apartment. They provide thermal insulation and tightness, but at the same time prevent the access of fresh air, which completely disrupts the system of natural air exchange, since the ventilation of plastic windows does not function.

Humidity - one of the consequences of installing plastic windows

Natural ventilation system provides for the receipt of fresh air in a fold of the size. The functioning of such a system is ensured by regular air conditioning on the street.

The regulatory standard suggests that the air exchange must be carried out at the calculation of the number of people, an average of 30 cubic meters per person per person, all envy.

It should be noted that the main array of buildings was built more than thirty years ago, when they did not even think about plastic in glazing. In the process of designing such structures it was assumed that the air outflow system operates through the ventilation channels in the bathroom and the kitchen. It was believed that the influx of fresh air would be ensured by opening windows and doors, as well as through the gaps, as a result of their leaks. Such a system was not progressive, but, nevertheless, led to the influx of fresh air to the apartment.

In connection with the installation of plastic windows, there is a different situation, namely, the process of natural ventilation is disturbed, which leads to irreversible consequences. Also, on the windows of PVC, the temperature of the temperature is formed on the temperature difference.

Negative effects from installing plastic windows

The use of plastic windows provides the tightness and preservation of heat, but leads to the fact that humidity begins to accumulate in the room, leading to the formation of dampness and mold.

The lack of ventilation of plastic windows contributes:

• enhance humidity in the design;
• formation of stuffiness and stagnation of air;
• the appearance of the feeling of lack of oxygen indoors;
• moving windows.

All this leads to deterioration of well-being, a decrease in performance and sleep disturbance at the inhabitants.
The absence of the influx of air masses into the room leads to the opposite result. Often it occurs when an air mass of other neighboring apartments come to the apartment.

Forced ventilation in an apartment with plastic windows is able to eliminate the existing shortcomings.

Types of ventilation systems

Manufacturers of PVC windows offer several options for solving ventilation problems in an apartment with plastic windows.

To improve ventilation, new designs have been developed on the PVC windows:

• the window is one of the most common ways in window structures, which provides for fresh air into the ceiling space, which gradually mixes with the apartment, refreshing it. The disadvantage of such a design is quite high the cost of the window due to the additional costs of the materials, besides, the unnecessary elements on the window itself make it less traffic permeable;
• with self-devented - are considered the most attractive option, which involves the presence at the top and bottom of the hole frame, passing through which the air is gradually warming up and enters the room. Disadvantage: Installing on the upper floors is not recommended, as it occurs shortage of air pressure. Suitable for both the private installation and industrial facilities;
• with a comb, the most widespread option, which implies the presence in the regulator window, allowing you to open the window in several modes. The mechanism is budget and expands the possibilities when carrying out;
• with the presence of a ventilation valve, an option that allows you to combine several functions to ensure work, which will allow regularly airing the room and observe the optimal temperature mode. Valves have several species that are distinguishable by the installation method. To install the valve on the PVC windows, it is necessary or to change the window, or, directly part that is responsible for ventilating. The installation of the element takes at least time, about one and a half hours, but provides the most favorable result. Thus, the valve provides a supply ventilation on plastic windows.

Valve valve for PVC windows

Popular hermetic PVC windows do not provide the optimal balance of inflow and air outflow? It is impossible to keep windows that are constantly open, especially in the cold season, when the resulting ice can cause a breakdown of the window mechanism. In addition, dust falls into the room, insects and all sounds from the street. Among the types of elimination of deficiencies, the most optimal option are ventilators for plastic windows, which supply the fresh air of the room and protect against the formation of condensate and dampness.

Variants of ventilation valves

Advantages of ventilation valves:

• preservation of human health through the creation of a positive microclimate;
• protection against mold, damp fungus, which leads to an increase in the life of the room and cosmetic repair in it;
• heat Saving in the apartment;
• protection against penetration of thieves, since the apartment is ventilated with closed windows;
• ease of use.

Thus, the ventilation valve is a system that allows you to provide a regular air inflow into the room and its circulation inside, with closed windows.

Ventilation valve is the best way to provide your housing with fresh air !!

The ventilation system is provided by automatic adjustment, since the sensor, determining, the degree of humidity in the apartment, the number of people and other elements, is embedded in the window, creating the optimal ventilation mode.

Types of valves of climatic supply ventilation:

1. folds - installed without dismantling windows, retains sound insulation. Air enters through certain holes in the focus. The most fiscal way;
2. sloves - do not require dismantling of PVC windows, is considered a fairly qualitative option. Air intake is carried out through the holes covered by the adjustment unit;
3. the overhead is the most modern option, it is considered the best in terms of air pass, but has a complex installation system. If they are not initially established, it will be impossible in the future, that is, ordering windows, the overhead valves are immediately ordered under the sizes of PVC windows;
4. mechanical - installed in the system of plastic windows with their own hands and allow you to ensure and carry out control over the influx of air yourself, manually changing the position of the valve;
5. automatic - ventilators for windows have an automatic hygrometer, which regulates air flow around the clock at any time of the year.

Ventilation in the windowsill

Ventilation in the apartment with plastic windows is provided not only by window systems, but also the ventilation of the window sills, which are the unchanged attribute of windows.

Ventilation in the windowsill is provided by a ventilation grid that adjusts the air flow from the battery to the window.

Thus, the supply window ventilation will additionally enrich air from radiators and batteries, which will ensure full-fledged regulation.

Conclusion

Plastic windows are a modern constructive solution that carries not only aesthetic function in the apartment, but also has an effective practical value. The shortcomings of PVC windows are easily eliminated with the help of modern ventilation systems, which will ensure air circulation and maintain health.
