Plastic windows significantly benefit in functionality in front of glass windows with wooden shutters. Stylish in appearance, with good sound insulation and the ability to maintain a comfortable temperature inside the room, regardless of external factors - all this has made plastic windows indispensable and mandatory in the construction of new houses.

However, they still have some disadvantages. In particular, this is the occurrence of difficulties in natural ventilation in the room, as a result of which various consequences can occur that affect the indoor climate and human health. But to prevent their occurrence is possible without the help of professionals, providing an additional flow of air. Why you can install the supply valve in a plastic window with your own hands, using improvised means.

And what is needed for this and how to properly perform the installation - we will analyze all this in detail in our article. We also talk about the manufacture of a makeshift valve and its effectiveness.

Functions of the supply valve in the window

The circulation of air in a closed room provides not only a regular change of air saturated with carbon dioxide to fresh, enriched with oxygen, but also in order to prevent:

  • condensation on the windows as a result of temperature differences indoors and outdoors;
  • education mold as a result of increased humidity indoors;
  • stale air, as well as an increase in the number of microbe and toxic substances in it;
  • physiologically perceived lack of oxygen, which leads to increased fatigue, headaches.

The stationary natural supply and exhaust system provided in each house should provide continuous systematic air exchange.

Ventilation ducts, which are usually found in the kitchen, in the bathroom and toilet, formed in them by natural draft pull warm polluted air. The formation of traction is possible with open windows or through the possible filtration of air through cracks in the frames.

Mold as a result of poor air exchange
Lack of proper ventilation leads to the formation of condensation on the windows and, as a result, an increase in air humidity and the appearance of mold. At the same time, the use of mold removing agents helps for a certain period of time. Without normal ventilation, the mold will reappear

This is the main disadvantage of natural ventilation - it was developed at a time when the possibility of the existence of plastic windows was out of the question.

Based on the physical laws of intake and removal of air from a room, it is not able to work if:

  • the ventilation system does not remove the exhaust air in the calculated volume (for example, it is contaminated and requires cleansing);
  • there is not enough air from outside.

Plastic windows are tight enough to provide a natural flow of air. Thus, the ventilation system is disrupted, which entails the formation of the above side effects that affect health.

Organization of airing rooms by opening windows is not always appropriate. So, in the spring-summer period of time when the apartment is cooled by air conditioners, opening the window leads to the flow of hot air, and can also cause breakdowns in the air conditioner.

It is worth noting that, according to sanitary requirements, airing of rooms should be carried out at a time when there are no people in them.

In the absence of normal air exchange, the room should be ventilated at least two to three times a day. However, with stable operation of the ventilation system, ventilating the room by opening windows is not necessary, since the air circulation provided by it complies with sanitary standards for enclosed spaces in which people can be

Thus, providing plastic windows with additional ventilation is a necessary measure.

Ways to improve indoor ventilation

Despite a significant minus - an obstacle to the natural circulation of air - the main advantages of plastic windows ensured their widespread use.

They really make life more comfortable, so quite progressive solutions have been developed to eliminate the deficiency:

  • special fittings providing restrictive opening of the window and low ventilation of the room;
  • wall supply valve;
  • window ventilation valve;
  • shutters with opening mechanism.

When choosing a method of providing ventilation, you need to choose the most convenient method of regulation - manual or auto.

Special fittingsbut does not provide constant air circulation, as it is based on opening a window and fixing a certain position. Nevertheless, at sharp high or low temperatures outside the window, its use is not justified from the point of view of maintaining the heat balance inside the room.

Butterfly valves (they are also called vent slats) have a lot of different options. Their regulation is done manually, and the installation should be designed at the stage of preliminary measurements. Ventilation slats are individual parts that are built directly into the window structure. Their main disadvantage is a complete violation of the noise insulation of plastic windows.

Pre-designed hole in a plastic window
When ordering windows from the manufacturer, you can pre-register the presence of a hole in the window. This design of windows violates the tightness and sound insulation and is not used for the organization of forced ventilation. But suitable for use as a hood for portable air conditioners

Wall Vent Valves There are different in design and method of air intake into the room. Simple ones have a ventilation grill on the outside and a special plug in the room.

Existing electrical options are equipped with fans, filters and air preheaters. These channels provide a global solution to the problem of air circulation, are used in large offices and places where air conditioners are constantly working. The main disadvantage of this solution to the ventilation problem is the need to make a through hole of a sufficiently large diameter in the outer wall. And any intervention in the facade of the building requires the permission of the management company and executive authorities.

And finally, the final kind of organization of ventilation in the room - window ventilation valve. Usually, they think about this ventilation system at the stage of ordering windows, however, when building a company’s houses, developers almost never think about these issues, leaving the solution to the issue of ventilation for future residents.

It is worth noting that construction standards provide for the presence of special ventilation valves in plastic windows.

You can solve the problem of ventilation of plastic windows with your own hands. Further, the article will consider the stages of the independent implementation of ventilation in a plastic window.

Installation instructions for the ventilation valve in the window

Modern supply valves are very practical in shape and easy to install.

The developers gave them a modern design, which, combined with the small size of the structure, allows you to fit perfectly into the plastic window without violating the overall design.

Valve on a plastic window
The supply valve has a miniature size and practically does not violate the tightness of the window. So, in the event of a slanting rain, it will ensure that the inside of the room is kept dry, and in strong winds it will ensure the supply of a certain amount of air defined by the manufacturer into the room

The main advantage of the ventilation valve is the round-the-clock supply of air to the room without the need to open windows.

There are two types of valves:

  • with manual control;
  • with automatic control.

The difference lies in the presence of sensors in automatic valves. They independently regulate the volume of supply air entering the room, depending on the readings of air humidity, the percentage of carbon dioxide in the room. The ventilation valve independently opens the valves more or less, letting the necessary amount of fresh air into the room. Also, automatic control valves provide manual control.

The main advantages of a ventilation window valve are:

  • the absence of noise with large volumes of air intake, its presence does not affect the sound insulation of the window;
  • filtering the air entering the room;
  • the ability to adjust the supply air volume;
  • air distribution in the room occurs in a vertical plane;
  • the ability to install on window profiles of any kind;
  • ease of installation of ventilation in a plastic window with your own hands.

Installing the valve in a window requires minimal construction skills and a small number of working tools. It consists of five stages.

Next, we consider the step-by-step process of mounting a valve in a window.

Stage # 1 - preparation of tools and materials

The first stage includes preparing the necessary tools and materials for work and determining the place where the valve will be installed.

In preparation, it is necessary to choose the following tools: stationery knife, screwdriver or screwdriver, double-sided tape, ruler.

Supply window device
The device and principle of operation of a standard valve: 1 - acoustic external visor; 2 - section for the passage of air; 3 - flap for manual control of air supply; 4 - the inner part of the acoustic valve; 5 - direction of the supply air stream

Now let's talk about the materials that are necessary for the manufacture and installation of the supply valve.

This will require:

  • a plastic headset that will play the role of a valve (or an acquired valve, the price of which is around 1000 rubles);
  • three segments of the sealant of different lengths (one along the length of the valve);
  • self-tapping screws;
  • three plugs for mounting the valve.

After the materials and tools have been prepared, it is necessary to determine the installation location of the ventilation valve. So, the valve should be located in the upper part of the sash and approximately in the middle. With the help of a ruler, the marking of the further location of the valve is made.

It is worth noting that when choosing a valve location, you should try not to hook the window fittings when installing.

Also at this stage, you need to prepare a plastic window for installation. Why carefully remove the rubber seal. Why, with the help of a clerical knife, neat cuts are made and a further removal of the sealant layer.

Stage # 2 - fixing the valve to the dowels

The second stage begins with installation in the grooves where the rubber seal was located, fixing dowels. This is necessary for further fastening the valve in the casement window.

Two fixing dowels are installed at the edges, and the third - in the center between the first two.

Window Mounting
When installing the supply valve, be sure to proceed carefully. It is important to choose the fasteners of the required length so as not to violate the tightness of the window frame. It is also important to properly install and avoid mechanical damage.

Next is the direct installation of the valve. To fix it, double-sided tape is applied first, after which the valve is installed on the window in the desired position.

After that, the valve is fixed to the window profile using self-tapping screws. They are screwed into the already installed dowels.

Stage # 3 - installation of the seal

At this stage, instead of the removed seal, it is necessary to insert two gaskets prepared or included in the ventilation valve kit.

The functioning of the valve provides air flow. To do this, the standard plastic window seal must be replaced with the seal from the kit. Its length is 35 cm, so it will be necessary to remove the same segment of the seal from the window. Removal is done on a frame opposite the installed valve.

On this, the process of installing the valve in a plastic window can be considered completed. It remains only to carry out its adjustment.

Stage # 4 - valve adjustment and adjustment

After installation, it is necessary to adjust the volume of air entering the room using a special engine provided in the valve design. The power level increases from the far left to the far right.

Functional installation of the supply ventilation valve on the window handle is considered quite functional. This operation is not performed independently - in order to arrange ventilation in the handle, you must pre-order this option from the window manufacturer

It should be noted that finding the air supply regulator (engine) in the leftmost position should only be during routine maintenance.

This valve position is not allowed for daily use. Also in this position can not be closed.

DIY valve manufacturing instructions

Despite the rather complicated design, the ventilation valve can be made by yourself. Further in the article, we consider the simplest manufacturing method.

The main function of the valve is to ensure free air flow into the room. At the heart of homemade work lies the physical property of air - when heated, its flows move up.

To make a homemade valve, you will need:

  • stationery knife;
  • a small piece of plastic lining;
  • double sided tape;
  • cotton wool or foam rubber.

Opening the window, we pay attention to the stationary rubber seal, which is applied around the perimeter to the window and frame.

In order to create the necessary air draft you need to perform the following steps:

  • in the lower part we cut a small piece of sealant from the window frame (size from 5 to 10 cm);
  • in the upper part we cut the same length of a piece of stationary rubber sealant, but directly from the window.

Thus, falling from the street into the space between the frame and the window, cold air will warm up and gradually exit through the upper hole into the room. The simplest device for providing air from outside is ready.

Window seal
The presence of a rubber seal ensures the tightness of plastic windows. The photo shows: 1- seal on the window frame; 2 - window seal

Many stop at this, however, with such ventilation, dust and dirt from the street will fall into the room, settling on the frame, window and penetrating inside.

To avoid this, you can do the following:

  • carefully cut the plastic lining across the section, making a strip a couple of millimeters wide;
  • fill the spaces of the plastic compartments with cotton or foam rubber;
  • fix the resulting structure using double-sided tape at the cut point of the stationary rubber seal.

An educated device in its functionality will not be inferior to supply air valves manufactured at the factory, and at a price it will come out much cheaper.

If this method of organizing the air flow seems difficult to you, we recommend that you read the instructions for window sill ventilation.
