Replacing wooden windows with plastic ones is perceived as a natural transition to a more reliable design. Excellent tightness of the latter is the main selection criterion. However, thanks to this quality, a reliable barrier to the flow of fresh air is created. Consequences - violation of the microclimate of the premises, increased humidity, the appearance of unwanted condensation on the windows. It is not necessary to return to the wooden classics. It is enough to provide a mechanism for micro-ventilation of plastic windows.

Micro-ventilation: purpose, principle of operation, problems to be solved

Micro-ventilation is a specific form of supply ventilation. For fresh air access, it is not necessary to open the window sashes several times a day for 10-15 minutes, which becomes problematic or impossible in frosty, windy, stormy weather. The inflow of outside air is ensured by creating a minimum gap between the movable sash and the frame of the plastic window, or it is regulated by a special valve with the sash tightly closed.

The lack of circulation and replacement of air with a simultaneous increase in humidity causes general discomfort, lethargy, and a decrease in the protective functions of the body. This microclimate promotes the rapid growth of fungi, bacteria and viruses.

How to make micro-ventilation on plastic windows

As for any type of ventilation, the purpose of micro-ventilation is to replace the "exhaust" air of the living space with fresh outside air. The air exchange rate can be calibrated and differ by an order of magnitude from full ventilation in the direction of decrease. Hence the term used for this type of ventilation.

It is possible to organize micro-ventilation on plastic windows with a slight change or addition to the design. The consequences will be significant:

constant air exchange is provided in the room;
lowering humidity will improve health, prevent the formation of fungus and mold;
fogging and condensation on glass;
there are no drafts, the doors do not close spontaneously;
without overcooling the room in winter, micro-ventilation does not create peak loads on the heating system; in summer, the metered intake of fresh air does not increase the temperature in the premises

The main methods of organizing micro-ventilation

Installation of the stop comb

The mechanism of the device is very simple, the operating principle is intuitive. Inexpensive "combs" are available in most hardware stores and firms that manufacture and install PVC windows. Self-installation does not require special skills.

The device, depending on the design, is mounted at the bottom at the sash angle or in the area of its handle. This method of micro-ventilation is multistage - the size of the supply gap between the sash and the frame is regulated by fixing the protruding pin in a certain groove of the comb.

Disadvantages of this method of ventilation: fragility of plastic parts; decrease in sound insulation properties of a slightly opened window; increased dust content of the seals, which will require additional maintenance.

Mechanism for micro-ventilation of plastic windows

Slot ventilation

Thanks to special fittings, the flap creates a ventilation gap of several millimeters at the top. Its value depends on the handle fixed at a certain angle (between horizontal and vertical positions).

With this method of ventilation, as with installing the comb, additional care of the seal material and the mandatory seasonal installation of a mosquito net will be required.

Important! Experts know how to make micro-ventilation on plastic windows without prejudice to their other functional characteristics. It is advisable to use the services of professionals when installing and setting up fittings for slot and valve ventilation.

Installation of climatic valves

In the upper part of the window, to the width of the supply valve, the seal is removed from the groove of the sash and window frame overlap. The valve is mounted in this place. If micro-ventilation of plastic windows is planned at the ordering stage, the ventilation valve can be built into the profile during the manufacture of the structure. The ventilation mechanism can have automatic and mechanical (manual) control, which allows you to calibrate the volume of the passed air. Installing the valve protects the room from insects, noise, dust.

Note! For previously installed window systems, a removable model of the supply valve is purchased. The non-removable version requires factory conditions and is installed during the production of windows.

Creating a comfortable microclimate, taking care of family health, with YSTEM mikroprovetrivaniya in plastic boxes are increasingly becoming mandatory for installation. The presence of this system even in budget models of window structures is now the norm among progressive manufacturers.
