Vent valve for plastic window. Kinds and advantages of this device

Previously, only the tree was used to make windows. Such models provided natural ventilation in the room . Air exchange was obtained due to leaky closing of the frames. Even the best quality wooden windows had cracks, which were closed only in the cold season. Modern manufacturers suggested replacing such models. To produce them, high-quality plastic is used, which has good heat and sound insulation. However, everything is not as rosy as it might seem at first glance. Plastic windows are so tight that they do not contribute to ventilation. Of course, you can open the flap for ventilation every two hours, but this is not very convenient, and not always there is an opportunity. To solve this problem, you can install a vent valve for the plastic window. It is this device that will control the atmosphere in the room, making it not only acceptable, but as comfortable as possible.

Types of Vent Valves

1. Seat valves. A simple way, but not very effective. The throughput of such devices is minimal, so they will not be able to provide full ventilation in a large room. Air falls into special cutouts in the vestibule, then passes through the rebate profile and penetrates into the room, bypassing the control valve. They do not violate sound insulation, their installation is possible after installation of the unit. Also, which is important for some families, the folded valve on the plastic window (price within 500 rubles) is quite affordable.
2. Slotted valves. Basically installed on the upper part of the leaf or on the impost, but always in a horizontal position. The movement of air is ensured by the slit on the inlet block, which is installed from the outside of the leaf, and the regulator is attached to the inner side. Such models are excellent for living quarters, as they can provide a sufficient level of ventilation. The slotted inlet valve on the plastic windows can be installed simultaneously with the unit or after the installation has been completed. The process of fastening itself will take about 1 hour.
3. Overhead ventilating valves. Unlike the first two types, such models are not attached to the already installed window unit, since their installation requires certain dimensions of the opening or frame. The device itself is large enough, and, as a rule, occupies almost the entire area of the profile. The overhead ventilation valve for the plastic window has a high throughput, which provides a good enough air movement, however in small rooms it is not recommended to use this method.

Basic requirements for the vent valve

These devices are purchased with one main purpose - to ensure full ventilation. Before buying, you need to make sure the quality of the device, it must meet two clearly formulated requirements.

1. Monitor the humidity in the room, after installation, the condensate on the glass should not form.
2. Ensure a full circulation of air and establish a microclimate in the room.

If the attached supply valve to the plastic windows does not fulfill these conditions, it must be replaced immediately.

Which is better: an open window or vent valve?

After the installation of plastic windows, the problem of drafts completely disappears, but a new one arises - the lack of ventilation. In order to ensure a constant ventilation, you will need to periodically open the window. But in this case, the flow of air can not be controlled, which can lead to severe supercooling, especially in winter. Also, this process is significantly hampered if the family has small children. An uncontrolled draft can trigger the onset of a cold. Especially this method is difficult for apartments located on the lower floors, there is a high probability of unauthorized entry. And here the manufacturers propose to install a vent valve for the plastic window. Its advantage over the open window is undeniable. The device does not affect the sound and heat insulation in any way, does not interfere with light penetration, ensures natural air movement and controls the humidity in the room.

Why do we need supply valves?

Plastic windows perfectly protect the apartment from street noise and keep the heat. Therefore, recently they have gained wide popularity. However, often after installation in the room, you can observe excessive stuffiness, stagnant air, dustiness, and the glass is often covered with condensate. The reason for all this is too good sealing, which disturbs the natural balance of air. If you constantly open the window for airing, then the room will be under continuous impact of drafts, and then the main function of plastic windows will be reduced to nothing. Again, there will be a noise from the street, and the air can be greatly supercooled. Then the question arises: how to solve this problem?

Now there is an alternative solution that will help control the microclimate in the room where the plastic windows are installed. Valves for ventilation allow maximum to provide comfortable conditions: to save from stagnant air and stuffiness, to normalize the humidity, while not creating drafts.

Adjustment of valves

It is very important to install the device in such a way that it is extremely easy to adjust the power. This mainly applies to mechanical models. But automatic are equipped with a special sensor with temperature control. It is enough simply to set the optimal parameters, and the device will itself control the surrounding atmosphere by closing the flap or, on the contrary, if necessary, opening it wider.

The vent valve for the plastic window is a modern solution to old problems. For a short enough period, it has proved itself only from the positive side, and its shape and design do not completely spoil the appearance of the surrounding space.
