When you mount new plastic windows, you may encounter many troubles, such as lack of air, mold formation, fogging of glasses. To avoid such problems, special attention should be paid to ventilation.
Steam in the apartment appears when cleaning, cooking, washing and other household activities. As a result, the level of humidity in the apartment can reach seventy percent. When breathing, a person identifies 18 liters of carbon dioxide per hour, and its concentration can become a critical. Therefore, it is important to find the optimal balance between wet streams and dry and find the optimal volume of dry flows, which should be at least 30 cubic meters every hour per person living in the room. Of course, if you installed high -quality windows in the cottage, you have nothing to worry about. But most often the quality of the windows leaves much to be desired.
Obvial-exhaust type of ventilation helps to achieve optimal air exchange between the room and the atmosphere.
Typically, in houses they are used to using the natural ventilation system – due to the difference in the pressure of cool air from the street and warm from the room. The air flow is provided through the gaps of window frames, through the doors, walls, it goes through exhaust channels in the kitchen or in plumbing rooms. However, such a system is not particularly effective. Drafts appear in cold weather, and in hot periods in the room it becomes stuffy.
Most hermetic windows prevent the penetration of air flows. In this case, there is no influx – there are no extracts, and the furniture and surrounding objects absorb moisture, which leads to condensate on the cold surface. Therefore, it is necessary to install forced ventilation.
