How to make ventilation in an apartment with plastic windows

Air exchange and ventilation in an apartment with plastic windows and in a private house is a matter of people’s comfort and health. There are many options on the market for oxygen circulation and supply systems. Sometimes it’s easier to open the window and ventilate, but often more complex technical solutions are required.

In a situation where bills for housing and communal services and heating are growing every year, an important characteristic of an apartment or private building has become its energy efficiency. This is how easily you can get a comfortable temperature in a room and how quickly it will drop without additional heating. The thermos has the best indicator, and sometimes buildings are built based on this shape. The ideal solution in this case is plastic windows. The glass unit is well insulated and, when properly installed, sealed.

But for a living room, air exchange is also important. In houses with old wooden frames, the flow of oxygen occurred through cracks in the windows, but double-glazed windows eliminated this problem. As a result, we are forced to carry out forced ventilation. Without it, the temperature and humidity rise uncontrollably, making it impossible to breathe.

How to ventilate a room without a window

If standard ventilation is needed, then a system of air ducts, one for supply, the other for exhaust, with mechanical motivation.
Install the ventilation equipment in any convenient place, no matter in the ventilated room or in an adjacent one. But the main condition for the effective operation of such a system will be its calculation performed by a specialist

Contact an organization that specializes in ventilation systems. If “just so that it doesn’t feel stuffy,” then you can accept the option “Kolhozzing rules”:

Without taking into account the ventilation system of the room from which you recommend taking air, it is generally unclear how this entire structure will work and whether it will work at all. Don’t forget about the noise from the fan, possible vibrations in the ventilation ducts...

And the first step to the right decision is to contact specialists. Before you begin arranging ventilation in a room without windows, you need to find out the level of draft. Multi-storey buildings use a system of natural circulation of air masses, the operation of which is based on the laying of special channels.

You can arrange supply ventilation, which is arranged using a pair of fans, a filter, a heater, and a hammer drill

This design is designed to remove excess moisture from the room, but it is important to correctly calculate the diameter of the hole so that the system effectively copes with the assigned task

Types of ventilation devices

The flow of clean air into the apartment is ensured by ventilation mechanisms of different types, presented in a wide variety on the market.

Recuperator for apartment Marley

A device with an exhaust hood and an influx of heated air at the same time is in demand. It looks like a small box with two fans, a filtration system, a recuperator and a control unit. The mechanical device is hung on the wall and does not require energy.

There are mechanical and electrical devices based on their operating principle.

Hoods installed above kitchen stoves, fans, air purifiers with heat exchange in the bathroom, toilet, and other rooms can be turned on automatically along with electricity or by mechanically pressing a button.

Electrostatic ionizers imbue purified apartment air with positive health properties.

An example of an air purifier with a method of ventilating the interior space of a room through the passage of several filters.

1. The primary pre-filter is made of foam or plastic mesh that is easy to wash and dry. Detains coarse dust, particles of pet hair, fluff, and hair. The better its quality, the longer the service of subsequent filters.
2. Behind it are installed filters for smaller dust particles with bacteria and fungi, which, when breathed, enter the lungs and cause significant damage to human health, especially those with asthma and allergies. Nera filters capture the smallest dust particles and purify the air up to 99%. The more filters, the better the cleaning system.
3. The last filtration is with activated carbon, in which volatile microparticles settle and are retained, and unpleasant odors go away along with them.

Instead of activated carbon, the air can be filtered by passing through water.

Mechanical devices do an excellent job of cleaning the microclimate inside an apartment; they are economical to use, but are expensive and require additional action to clean the primary filter, replace water, etc.

A properly selected method of ventilating an apartment with plastic windows should be silent, without temperature changes, with normal humidity, the air environment should maintain a cheerful mood and health.

Description

A conventional window hood is a compact device with low weight. It is installed in a window opening and significantly improves air circulation indoors. Using such a mechanism, it is possible to organize full ventilation of the room and ventilation of individual zones.

A lightweight fan is attached in two ways: on top of a window (wooden, plastic) or replaces a small part of it. Often it is covered with blinds or curtains. The latter open during operation of the device.

This hood operates completely silently and allows you to quickly freshen the air in the room. Its use is considered more hygienic than opening a window, since it prevents dust from entering the room.

Options for arranging forced ventilation of plastic windows

There are several options for solving the problem of air flow into a room with plastic windows:

• slot ventilation;
• self-ventilation device;
• window with discrete fixation or sash lock;
• supply valve.

Each of the proposed options for ventilation of plastic windows has its pros and cons. For example, a window makes the glass unit heavier and increases its cost.

Slit ventilation

Ventilation of plastic windows through micro-slits is provided for by the frame design. If you turn the handle of the tilt-and-turn sash 30-45 degrees from the vertical position, the window will not close completely. Air from the street will be effectively blown into the remaining gap.

This ventilation option does not require additional costs and is the most popular. Disadvantages include poor air flow in the warm season and constant draft in winter.

Self-ventilation

A self-ventilation device in a plastic window is provided at the stage of manufacturing the structure in the form of special holes in the frame. Air is taken from the street through holes in the profile located in the lower part of the frame; air enters the room through the holes in the upper part.

Passing between the doors, the cold flow has time to heat up and comfortable fresh air enters the room. Plastic windows with self-ventilation are more expensive than simple ones.

Window lock or discrete sash fixation

A window retainer (comb) is a special hook that secures a frame or window in a half-open position. The hook has several fixing grooves, which allows you to regulate the strength of the air flow. The device is inexpensive, simple and reliable. It can be independently installed on any plastic frame.

The discrete sash locking mechanism performs the same function as a window lock. The difference is that it is built into the frame and is not visible from the outside. Double-glazed windows with a discrete lock are more expensive than simple plastic window structures.

Supply valve

A supply ventilation valve for plastic windows is the most complex and expensive device for forced ventilation. Manufacturers offer supply valves with different capacities, different colors and different prices. The supply valve can be installed on a plastic window, either during its manufacture or on an already installed double-glazed window. The valve should be selected based on the area of ​​the room.

Inlet valves operate automatically or manually. Automatic valves are activated when humidity and air temperature increase.

If you need to install a supply valve in the kitchen, then the best option would be to use a mechanical device. It can be used periodically, in manual mode, when intensive ventilation of the kitchen is needed. The rest of the time, air flow from the rooms will be sufficient for the kitchen.

Ventilated façade: purpose and design

In the modern industry of construction of residential multi-storey buildings, a ventilated facade has become a popular solution - a simple and practical design that protects walls from atmospheric influences and performs an aesthetic function. Most often it comes in the form of porcelain stoneware slabs, which are fixed to the wall with special fasteners. At the same time, a small gap remains between the wall insulation and the slabs - thanks to it, ventilation is ensured, moisture and excess heat are removed from the façade space.

The ventilated facade meets all the requirements of mass construction - it is quickly assembled, it is easy to install, and in the future it allows you to reduce the cost of major repairs. Since management companies are responsible for maintaining such structures, they are responsible for compliance with the requirements of regulatory authorities for the appearance of the facade; therefore, third parties are prohibited from changing or reconstructing it.

How to install it yourself?

As already mentioned, supply valves (diffusers), which you can install yourself, will help ensure good ventilation in PVC windows. They are mounted on the frame and sash of the window and do not in any way affect the attractiveness of the window and the interior as a whole.

You can install diffusers yourself without involving outside experts. You don't need to have any special skills. By following the tips below, the entire process can be completed in 50-60 minutes.

To install the ventilation valve you will need:

• the valve itself (35 cm long);
• stationery knife;
• screwdriver or screwdriver;
• ruler or template.

All required parts for installing the diffuser must come with it:

• a piece of sealant 35 cm long;
• 2 seals, 16 cm each;
• three plugs for attaching the valve;
• self-tapping screws

We determine the location of the valve installation. The diffuser is placed on top of the window frame. Approximately in the center of the frame, use a ruler or a pre-prepared template to mark the place where the valve will be installed. Important: If the sash is narrow, you may have to move to the side so as not to get on the window fittings.

We remove the standard seal between the marks made

Using a knife, you need to carefully make cuts on the sides, after which the rubber product can be removed from the grooves without unnecessary difficulties.

Installing dowels for fastening In the holes where you pulled out the old seal, insert 3 fastening dowels (2 on the sides, 1 in the center). They will allow you to secure the valve to the frame.

At this stage we fix the valve itself

For convenience, it is recommended to apply double-sided tape (without protective film) to the product in advance.

We attach the valve to the frame using self-tapping screws. They should be screwed into previously installed dowels. After this, the valve will be considered securely fixed.

We install a new seal. Instead of the previous option, we place two 16 cm seals between the valve mounts (sold complete with the device).

We change the standard seal on the frame. This is necessary so that the air exchange in your home never stops. Mark a 35 cm section on the frame directly opposite the flap you just attached. We remove the seal that is there, and in its place we insert a substitute from the kit.

Windows with combs

The device owes its name to its external resemblance to a hair care product. This window ventilation system operates on the principle of adjustable opening in several modes.

The low price does not affect the efficiency of the mechanism.

The fixed position of the open frame allows you to control the volume of incoming air, preventing the formation of drafts.

Micro-ventilation – always fresh air in the apartment

Is additional ventilation really necessary if residential premises are initially equipped with ventilation systems? The supply and exhaust circuit already guarantees constant air exchange, the norms of which can be found independently in the SNiP documentation.

Thanks to the natural impulse that underlies most ventilation systems, the air exchange rate is maintained. The multiplicity values ​​are set out in SNiP 2.08.01-89*.

Inlet valve matched to the frame texture

If in summer open shutters can compete with micro-ventilation devices, then at -15ºC it is unlikely that anyone will agree to open windows wide. Thus, special valves and devices provide fresh air flow, protect against condensation, do not create drafts, and do not require constant attention or maintenance. But you need to remember that for the normal operation of the supply units, proper exhaust ventilation is necessary.

How to improve air circulation?

After checking, many decide to improve the efficiency of the system. This is easy to do by improving the flow of fresh air. Do-it-yourself ventilation in an apartment should begin again with a check. Take a piece of paper and place it near the channel opening, but at the same time the front door and windows must be tightly closed, and the interior doors must be completely open.

If the channels do not function sufficiently and the “test” paper falls, you need to check for a gap between the floor and the bottom of the doors. It should be 3-5 centimeters, because only in this case will ventilation in an apartment with plastic windows be optimal. If this option is not suitable, drilling several rows of holes 1-1.5 cm in diameter is allowed.

In a toilet, bathroom or bedroom, drilling holes can be done with an inclination towards the inside of the room. This approach eliminates the possibility of peeking into existing cracks. To improve sound insulation, a special mesh made of stainless steel or steel is installed. After completing the described steps, ventilation in the apartment improves.

Installation instructions for window sill ventilation

Depending on the method chosen to create ventilation in the window sill under plastic windows, the homeowner or craftsman will have to perform certain manipulations.

Option #1 - drilling holes with grille overlay

This is the easiest and fastest way to slightly improve the circulation of warm air generated by a heating radiator.

A decorative overhead ventilation grille in the window sill hides the holes made and looks aesthetically pleasing. When installing, you should be careful and place the product so that the angle of the slats is directed towards the glass unit

For installation you will need: a screwdriver (drill) with a drill, a pencil for marking, a ruler, an overhead grid of the required size, glue for fixing.

After preparing the necessary equipment, you need to follow a few simple steps:

1. Compare the dimensions of the purchased ventilation grille and the length of the window sill to place the trim in the center, maintaining equal distances from the edges of the window sill, and make notches with a pencil.
2. Attach the grille to the window sill, focusing on the marked notches, outline its perimeter.
3. Inside the outlined area, make multiple holes with a drill, retreating from the pencil line by about 1-1.5 cm.
4. Cover the perforated area of ​​the window sill with a ventilation grill, securing it with glue.

In fact, all work can be completed in less than half an hour. Plastic shavings remaining after drilling can be easily removed with a vacuum cleaner.

Advantages: quick and easy implementation, minimal set of tools, simple preparation for installation. But such a grill protrudes above the level of the window sill. Also among the disadvantages is a decrease in the efficiency of the lattice cross-section.

Such measures will make it possible to slightly improve air circulation and partially solve the problem of condensate settling.

Option #2 - installing a grille with cutting a groove

This method of installing a window sill ventilation system is no more complicated than the previous one, but it allows you to more aesthetically hide an improvised ventilation duct in the thickness of the window sill if you use a built-in ventilation grille.

Such grilles fit more organically into the interior, since they do not rise above the level of the window sill. You can safely place indoor flowers on them without worrying about the stability of the pot

However, a similar method can also be used to install an overhead product.

In addition to the tools listed above in the description of the first method, you will also need:

• jigsaw or grinder;
• a heavy object to use as a press if the grille is fixed with glue;
• bolts, if the grille is secured with them.

After the preparatory work has been completed to mark the place where the grille will be located, you must perform the following steps:

1. Drill four holes at the corner notches. The diameter of the drill bit should be larger than the width of the jigsaw cutting blade.
2. Inserting the jigsaw blade into one of the resulting holes, cut out a groove.
3. Insert the grate into the hole to make sure it fits properly.
4. Secure the grille with glue or bolts. When using glue, use a press for better adhesion to the window sill.

If desired, you can use neither glue nor bolts. Free dismantling of the grill will greatly facilitate its care, since the product can be taken out and washed with water at any time.

Advantages of this method:

• ease of installation;
• installing the grille flush with the window sill;
• aesthetic appearance.

Disadvantages include the need for more tools and damage to the integrity of the window sill.

This window sill ventilation system looks quite aesthetically pleasing, allowing the surface to be fully used as a storage area.

Option #3 - installation of supply window sill ventilation

This is the most labor-intensive, but also the most effective way to correct air flow.

An additional ventilation duct with a supply valve is not only extremely efficient, but also looks quite attractive both inside and outside the building

This measure allows you to fully replace heavy indoor air with fresh outdoor air and get rid of excess moisture that causes condensation to settle.

The main working tool for installation will be a hammer drill with a crown capable of making a hole in the wall of the required diameter. Check for draft in the apartment ventilation duct. If the ventilation system is working properly, proceed with installation.

Procedure:

1. Select installation location. The optimal area would be between the heating radiator and the window sill itself.
2. Disassemble the purchased product by disconnecting the internal unit from it. Mark the installation location, focusing on the mounting points of the box.
3. Using a hammer drill, drill the exit hole for the future channel at a slight downward angle.
4. Wrap the vent pipe with insulation and install it into the duct. The outer part of the device must be flush with the wall surface.
5. Following the instructions for the device, install soundproofing membranes and air filters. If the valve has a fan to generate additional air flow, connect this unit to the wiring, based on the connection diagram in the passport.
6. Secure the inner box with dowels.

More detailed instructions for installing a supply valve into a wall are given in the following article.

The installed ventilation system requires minimal maintenance. However, the user should still clean or change the filters at least once a year so that the equipment does not lose its efficiency.

Advantages of this option:

• the most effective method of ventilation;
• complete air exchange;
• removing excess moisture from the room.

Disadvantages include more complex installation, damage to the integrity of the wall, and higher cost of work due to the price of the valve that has to be purchased.

It is still more appropriate to entrust the selection of the supply valve and the work to a specialist. The technician will be able to accurately calculate the required equipment performance and install it correctly.

Exhaust ventilation system

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

If you notice that you have a long-lasting smell after cooking, or “odors” from the bathroom and toilet rooms, this is evidence of insufficient or completely absent ventilation. Very often this phenomenon is observed after replacing conventional wooden frames with plastic double-glazed windows.

You can check the functioning of the built-in ventilation system in a simple way: just hold 5X15 cm strips of paper to the ventilation grille and monitor its condition:

• If the paper remains motionless, the ventilation system is not working. Open all the windows and hold the paper to the ventilation grill again.
• If the paper sticks to the grille when the windows are open, the channels are working and the problem is the supply of fresh air. This happens especially often in apartments with plastic windows, where natural ventilation from the outside is difficult.
• When, even with the windows open, the paper does not stick to the grille or barely moves, it is necessary to clean the air channels. Due to accumulated dust or dirt, debris, and insects, air movement through them is difficult.

Local ventilation ducts are installed in the kitchen and bathroom. Considering the particularly polluted and humid air, you can enhance the operation of the ventilation system here with the help of an exhaust fan.

Kitchens in the food preparation area must be equipped with a hood. Its use helps prevent the spread of kitchen odors and fumes throughout all living spaces.

To ensure ventilation in the bathroom, it is recommended to use an electric built-in fan. Given the high air humidity, it must have reliable protection from water. Fans of this level are marked IPx4. Exhaust fans are also required to operate quietly and have a production capacity of 50 or more m3 of air per hour.

Windows with a window

The easiest way to ventilate rooms with plastic windows. To ensure ventilation, the window structure is equipped with an additional element - a window.

Better ventilation is facilitated by air entering the room from the ventilation hole under the ceiling. The optimal microclimate in the room is formed by mixing air flows from the room and from the street.

This method of ventilating a home with plastic windows allows you to avoid drafts, while simultaneously preventing the formation of condensation on the glass.

The disadvantage of vent ventilation is its complicated design, which increases the weight of the system. In addition, the presence of additional frame elements reduces the luminous flux.

What can be done in such cases?

No, you don’t need to replace good plastic windows with old wooden ones. In addition, no one suggests you open them wide during the cold season and let your apartment cool down.

Today there are windows with micro-ventilation that provide good air exchange. Such windows allow you to maintain a regular flow of fresh air into the apartment, thereby regulating temperature and humidity, will not create drafts, and will ensure the creation of a comfortable microclimate in your home.

Our task is to introduce you to each method in more detail so that you can independently choose the option that suits you best. Read about the consequences of poor ventilation and other ways to ventilate a room on the next page of our resource.

Attic and basement ventilation without dormer windows

When building a private house, the issue of ventilation is very important. The less heat loss from open windows, the less energy required for heating. When adding piping to the project to supply air to all rooms, we must not forget about the space under the roof and the basement. Ventilation windows are needed in the attic, even if it is cold and well insulated. It will not allow the rafters to rot, the insulation to become damp and mold to appear.

Free space in the basement or attic can be used to install recovery and air exchange systems and lay pipes throughout the house. Fence grilles can be installed on the gables. Then the ventilation of the attic or basement will take place without dormer windows.

Attic ventilation

Supply valves

Supply (or ventilation) valves are divided into window and wall valves. Ventilation supply valves on plastic windows can be easily installed independently in 15 minutes; Installing a wall valve is a little more difficult because you have to make a hole in the wall.

These devices have many advantages:

• It is possible to regulate the air flow (manually or automatically).
• The windows stop fogging up.
• The valve is inexpensive - from 600 rubles.
• The device is quite easy to install and maintain.

Unfortunately, there are also a lot of disadvantages:

• Window ventilation valves are equipped with a maximum of one filter – coarse filter. That is, all harmful gases, particles and fine dust will remain in the room.
• The performance of the device is not very high. The fresh air entering through the valve is usually only enough for one person.
• In winter, the valves on the windows for ventilation often freeze and stop working.

By the way, there is also a valve handle

. This window ventilator is installed in the window profile instead of a conventional handle. It works in the same way as other valves, but is less common.

Is it possible to organize a ventilation process with an exhaust hood?

If you do not want to purchase combs, valves and plugs for plastic windows for ventilation, pay attention to the possibility of organizing a hood.
Along with standard ventilation systems, it can effectively remove contaminated air masses from premises. For reference:
Most often, a hood is provided in an apartment at the stage of construction of the building. However, due to depressurization of air ducts, clogging and a number of other reasons, its effectiveness can be significantly reduced.

Solution

Installing an exhaust fan in a wall or window is an affordable way to ensure high-quality air exchange even in a spacious room and/or a room where the air is significantly polluted or humidified (in the kitchen, bathroom, etc.).

To solve two issues at the same time - organizing ventilation and removing exhaust flows, we recommend installing fans that work both for the supply and exhaust of air masses. Installing one functional device will be cheaper and will save space and time.

Types of ventilation in the apartment

There are many types of systems and installations, including mechanical, general exchange, local, duct, and non-duct ventilation. Let's look at the most common types for apartment buildings and private buildings.

Natural

Most often, in apartments and houses, ventilation is natural - ventilation is carried out without the use of special equipment or artificial ventilation. Air enters independently, through windows, doors, and leaks in the walls. It comes out through hoods in bathrooms and kitchens. The scheme is simple: it is pulled from the room into the ventilation shaft and, rising up, exits through the roof. The functioning of natural ventilation occurs due to the difference in pressure outside and inside the house, as well as due to temperature differences.

Natural ventilation - this option is the most primitive, cheap, but unreliable.

The main advantage is the affordable organization of this type of system in a private house and in a multi-story building. Of course, there are certain nuances: for example, very little air passes through the strong double-glazed windows on the windows, so the room is stuffy. If the hood is clogged, circulation is disrupted - stuffiness and mustiness appear.

In apartments with two-way orientation, natural ventilation can work well most of the year if it is correctly designed and installed.

Forced

Forced ventilation is a special system in an apartment that ensures a constant supply of air masses inside, regardless of the weather outside. This type of ventilation allows you to completely control the inflow rate and adjust the entire equipment process to the need for air exchange. The work process does not require manual control, you do not have to open a window - it is fast and convenient for use at home.

Forced ventilation in an apartment is considered the most effective.

Supply

The system consists of a heater, cooler, filters and a device for receiving and supplying air masses into the house. There are two categories: monoblock and typesetting.

Properly organized supply ventilation in an apartment is the basis for a comfortable microclimate in a living space.

Exhaust

Using the exhaust system, exhaust air, unpleasant odors, dust, and pet hair are removed outside. To enhance natural exhaust, you can install a fan in it, having previously calculated the area of ​​the room

This is important so as not to lose performance

Ventilation is considered sufficient when exhaust air in each room is completely replaced with fresh air at least twice an hour.

Supply and exhaust

This type provides at the same time the influx of fresh air and the removal of exhaust air.

Supply and exhaust ventilation in a private house can be organized with your own hands.

Additional recovery units

There are different types of heat exchangers in the ventilation system: rotary, plate and counterflow plate. Rotary ones look like a circle, inside of which there are corrugated sheets of metal. An electric motor is installed that starts the recuperator.

A supply and exhaust unit with heat recovery solves the problem of heating the air in winter.

Breezers and recuperators

The problem with supplying cold air, typical for wall dampers, has been solved in breathers - local air supply units equipped with a fan and an electric heating element. Advantages of the unit:

• three stages of influent purification - in a coarse, fine and sorption (carbon) filter;
• heating the air to the set temperature;
• automatic and manual control of fan performance;
• air quality monitoring – measuring humidity, temperature and carbon dioxide concentration;
• partial recirculation - return of room air after filtration - allows you to save energy;
• remote control from a remote control or smartphone.

Let us note 3 disadvantages of the unit: operating costs for electricity, high cost of the breather and its repair in case of failure. There is no point in describing the installation technology - the household appliance is built into the wall in the same way as a valve.

Breather device - local air supply unit

Reference. With the help of breathers it is convenient and comfortable to ventilate any living space. But it is difficult to call the units generally available - the price of products from the famous Tion brand starts from 300 USD. e.

A wall recuperator, a supply and exhaust unit capable of removing heat from the exhaust air, will cost even more. There are 3 types of installations, differing in cost and principle of operation:

1. Reversible (sellers call them regenerative). The operating algorithm is simple: first, the exhaust air heats the ceramic heat accumulator, then the only fan changes the flow direction and the element releases the accumulated heat to the influent. The cycle is repeated at intervals of about 1 minute.
2. Rotary. There are 2 fans constantly running here - supply and exhaust. Both streams pass through a rotating rotary heat exchanger, exchanging heat.
3. Cross flow. The exhaust air transfers heat to the supply air through the thin walls of an aluminum or copper heat exchanger. The fans direct the flow towards each other, as shown in the diagram.

The most effective recovery option is in a cross heat exchanger, which allows you to return about 70% of the thermal energy back into the room. The efficiency of the rotary unit is slightly lower - about 5%. The actual heat transfer rates in reversible units are unknown, and sellers, as usual, overestimate the efficiency of these recuperators.

How to improve ventilation in an apartment that has plastic windows

Before you decorate your apartment with such a thing as plastic windows, make sure that the model you choose has a window ventilator.

Purchasing and installing an air recuperator, which is a kind of heat exchanger, will also help solve the problem. On average, it can serve up to 25-26 m², although this directly depends on the characteristics and properties of the device. The ideal ratio is one piece of equipment in each room. Among its main advantages are low energy consumption, quiet operation, and low cost. Also, their undoubted advantage is installation at any stage of repair, be it its beginning or completion.

Supply ventilation has a number of advantages:

• is adjusted automatically - not using the control panel, but by itself. This function is quite convenient, because you do not need to monitor the device; it itself determines when it is necessary to replace dirty air;
• change in air temperature: the equipment can both heat and cool the air. Temperature indicators depend on the source air in the apartment;
• Another advantage of mechanical ventilation over natural ventilation is that it is able to purify the air before it enters the room. So you don’t have to worry about breathing air that contains harmful substances. There are plenty of them on the street too.

Another option that will help you with fresh air in your home is a fresh air vent. As a rule, it is mounted in the window itself. Such valves can be improved with various filters and other devices, but this is not mandatory. The vent valve, like all other equipment, helps fresh air get inside. Depending on the needs of the apartment residents, its quantity can be adjusted and installed independently. How many of them need to be installed in the house? In fact, it all depends on the square footage of both the entire apartment and each individual room. For the valves to work properly, there must be an exhaust hood in the house.

In fact, there is nothing wrong with the lack of natural ventilation when installing plastic windows, because any problem can be solved. Just use any type of forced ventilation, the one that is most convenient for you. In any case, thanks to simple devices, you can breathe purified air in your apartment and not worry about your health.

Why is this method not popular?

The first thing that clients usually fear is that there is glass wool under the ventilated facade and it can fly into the apartment. But, because According to construction standards, this insulation is sheathed on top with a fire-resistant film, then all the glass wool remains “under the package”. But the risks are quite real, because... developers and the quality of construction vary; in some places they may not use film at all, but in others they use low-quality material, and the film may tear.

There is also an opinion that exhaust gases from warming up cars can be drawn under the facade in winter. If the ventilation façade is installed without gaps between the slabs, then it will be so. There is another reason why this installation option looks dubious - it is the heating of the ventilated facade in sunny weather. In hot weather, the air in the space behind the facade will warm up more than the outside air: this means that a working “inlet” will create stuffiness in the apartment. But there is also a downside - in winter, the air under the ventilated façade is warmer than outside, so you can save on heating.

Is it possible to avoid all the problems listed above when installing a ventilator, and at the same time do without through-drilling the facade? It is possible if you install the ventilator on a slope.

Multi-stage “comb” ventilation mechanism

• It will ensure constant air exchange in the apartment without drafts.
• Thanks to the “comb” mechanism, condensation does not form on the windows and windowsill.
• Using a comb will provide fresh air to your apartment without overcooling it.
• The mechanism has latches, so it will never close on its own.

In ordinary PVC windows, the handle has 3 positions. Horizontally - completely open, vertically upward - open for ventilation, and the handle vertically lowered down - completely closed. With the “comb” installed, intermediate positions of the handle also appear at 60.45 and 30 degrees. In these positions, ventilation gaps of different sizes appear.

Technical specifications

The average power of a household fan mounted in a window is 20 W. This indicator is quite sufficient to ensure proper air exchange indoors and high-quality air purification. The rotation speed of the blades of such mechanisms is 3 thousand rpm.

The window fan housing is usually made of durable plastic, which is extremely resistant to external atmospheric influences and temperature changes. It tolerates temperatures ranging from -50 to 50° C.

The use of devices with a lid or blinds allows you to avoid large heat losses. When lowering the latter, the device automatically turns off. In order to increase the thermal insulation characteristics, the strips of protective elements are equipped with soft rubber seals: they prevent the formation of cracks.

Composition of the forced ventilation system

Mechanical ventilation systems consist of supply branches and exhaust ducts. For proper operation, it is necessary that they are calculated correctly and compensate each other. Air balance must be maintained in the apartment. The inlet part may consist of the following elements:

• air supply unit and natural exhaust system (through ventilation shafts);
• supply unit and exhaust fans;
• supply and exhaust system with recuperator;
• mechanical exhaust and supply valves (wall or window).

It is more convenient to calculate and configure a system with mechanical inflow and exhaust.

Air handling unit with recuperator in the apartment.

The use of units with a recuperator allows you to reduce the cost of heating fresh air, but you need to carefully calculate the air exchange. Such a unit does not take into account the presence of separate exhaust systems from the kitchen stove and the bathroom (which cannot be combined into one network with residential premises).

Supply valves are simple and cheap devices, but they do not allow you to regulate the amount of supplied air within the required limits. Large rooms require the installation of several of these valves. It all depends on the quality and correct choice of exhaust devices.

Is it necessary to additionally ventilate a frame house?

The airtightness indicators in a frame house are high if it is built using modern technologies. Natural ventilation works well only in winter, but reduces the temperature in the premises. For permanent residence, a compulsory system is required. The design is no different from those installed in apartments.

The type of system depends on the area and features of the house. The most economical option is natural inflow and forced outflow. But such ventilation lowers the temperature in the rooms. Therefore, it is better to install an expensive structure that maintains the established temperature and humidity parameters.

All of the above does not apply to a house or cottage in which people live periodically. In summer, ventilation is provided by ventilation.

Condensation on the surface of the window glass

From time to time, despite all the tricks aimed at reducing the level of humidity in the room, condensation still appears on the window glass. Many people use various folk remedies to combat it, wipe the windows with dry napkins and rags, and additionally ventilate the room afterward.

Only ventilation grilles for window sills will help you cope with the emerging situation once and for all. Only they will keep the window profile dry, thereby extending its service life for a long time.

Types of devices

A grill installed in the window sill more effectively distributes the flow of warm air near the window, preventing the accumulation of liquid on the glass.

There are many varieties of these devices:

• external, internal and transfer;
• unregulated, adjustable and inertial.

In addition, depending on the type of materials used, gratings are divided into:

• polymer - one of the most common materials, which over time can turn yellow and warp from exposure to high temperatures;
• aluminum - have a good light weight and appearance, the disadvantage is a high price;
• made of wood - goes well with any type of room design, but requires care and special attention;
• metal - have enormous weight, price and attractive appearance.

Installing gratings on a window sill

To independently install devices that help eliminate condensation from the surface of window glass and frame, you need to stock up on the following tools:

• drill;
• marker;
• jigsaw;
• glue for joining polymers;
• weight to secure the grille during installation.

The sequence of actions for installing the grille on the window sill is as follows:

1. A pre-purchased device is applied to the window sill, which is outlined along the contour with a pencil or marker.
2. Holes are made in the corners of the resulting figure using a drill. Their diameter should be slightly larger than the width of the jigsaw blade.
3. After this, a part of the window sill is cut out along the drawn lines. In the future, the place of the removed part will be taken by a decorative grille, providing free access to heated air.
4. Then gluing is done. Excess adhesive must be immediately removed with cotton or linen cloth. Once the glue has hardened, this will be problematic.
5. Before complete polymerization, a weight must be placed on the attached ventilation grille.

Window fittings

Metal parts will ensure the window opens in different planes

When assembling a window, metal parts are installed in a groove on the profile, which provide various opening positions and clamping of the sash in the closed position. A micro-ventilation mechanism can be included in this system. Ideally, it is installed immediately at the time of assembly at the factory.

But if the window was installed a long time ago, it is quite possible to install the mechanism on site. To do this, you should contact specialists. Any company engaged in the repair of metal-plastic structures provides this service.

The mechanism fixes the gap between the sash and the frame, sufficient for air flow (no more than 3 mm). It usually opens by turning the handle 45 degrees. There are multi-stage locking mechanisms (handle rotation by 15, 45 and 60 degrees).
