The windows are sweating - how unpleasant. This phenomenon, which manifests itself only during the operation of windows. In other words, this shortcoming is invisible, immediately when installing metal-plastic windows. And, when fogging, do not eliminate this defect yourself, it is better to seek advice and debugging the design in a specialized firm or the company that installed the windows, most often, this defect manifests itself during the warranty period.
How to find the reason: why the windows on the balconysweat
What is the problem of this phenomenon?Customers often say - fogging glass, but in science there is a term for this phenomenon - the dew point or condensation. How condensate forms, many are aware of the school course of physics, and the fact that the environment has many parameters. And one of them and the most important is the humidity of the air.
If the air temperature on the loggia or on the balcony drops to such an extent, the moisture that is in the air in the gaseous state becomes a liquid state. And these droplets settle on surfaces that are at the temperature boundaries and condensation occurs, and the plastic windows get fogged.
There is no condensation in the warm season, as there is no main reason for the formation - a large temperature difference between the indoor rooms and the outside air.
It is noticed that the glazing of the balcony misted up, and not the balcony door. Why does this happen?In cold weather, the air temperature on the balcony will be slightly lower than in the room. But at the same time, it will be higher than in the street, and therefore misting up is the glazing of the balcony or loggia on the inside. At minus temperatures, the condensate on the windows turns into ice.
What should be done in this situation, how to deal with condensate:
- Eliminate dampness in the room;
- Improve ventilation in the room;
- Insulate and heat the room( balcony);
- Provide quality installation and competent selection of profiles and designs of plastic windows.
But there are more serious reasons why the windows are sweating. One of the main reasons is the defect of the profiles or fittings or the marriage when installing plastic windows. Most often, this is a loose fit of the rubber seal. But the main reason for the appearance of moisture on the glass balcony or loggia - this is excessive tightness. In other words, the main advantage of plastic windows, is also the main reason for the appearance of condensate.
Troubleshooting: when the windows on the balcony sweat
The best thing you can do is to improve the ventilation in the room. First of all, install the ventilation valves. They are window and wall. The window ventilation valve is installed in the upper wing of the profile of the plastic window. The simplest systems consist of a plastic grid and a check valve. Installation of these systems can be performed at home without dismantling the profile of the window.
The wall ventilation valve is installed in the wall. For mounting the wall valve, it is necessary to drill a hole in the wall of the required diameter, and mount the valve, according to the enclosed instructions. There is an even cheaper way to eliminate dampness in the room - this is a device of "crevice ventilation".
You can simply ventilate the balcony, opening it for 15-20 minutes in the morning and in the evening, even in severe frosts. But no more, otherwise you can achieve the opposite effect.
Another reason is excessive humidity( leakage or dripping of rain or snow from the upper floors).Therefore, this factor should be taken into account. If all the same it happened, it is necessary, either to call a specialist, or to self-seal the cracks with waterproof sealant.
What needs to be done to improve ventilation:
- Install the supply air valve;
- Install the "slot ventilation" device;
- Periodically ventilate the balcony;
- Eliminate the flow of rain and snow from the street.
The second cause of condensation on the windows is the cold and the large temperature difference between the room and the outside air. This can be avoided by warming and heating the balcony. This method is quite expensive and expensive. The balcony can be insulated with various heat-insulating materials - mineral wool, polystyrene foam or foam. The last heater is most suitable for the balcony insulation. It must be laid strictly according to the manufacturer's instructions. The floor, the ceiling, and the fences of the balcony or loggia are to be insulated. Necessarily the heater is sheathed with decorative material, and a vapor barrier is laid.
Also in the room it is best to install an electric heater( electric convector) or, if the means permit, put a warm floor. In this case, it is best to use heating mats. But all this must be mounted during roughing.
What you need to do when the windows on the balcony
get fogged up. When fogging windows on a balcony, it's important to remember that the right choice of plastic window profiles and quality glazing is the most important thing to never know what a sweating window is. To the choice of the manufacturer of the manufacturer of plastic windows and firms that produce glazing installation, it is necessary to approach carefully.
It's important to remember in a situation where the windows are misted up:
- Correct choice of profiles;
- Quality installation of windows;
- Heating and ventilation.
But if the window gets fogged inside the glass unit, this can not be fixed. In this case, it is necessary only one - to completely change the double-glazed windows. At the same time, it is necessary to know that only the manufacturer is to blame for this. At low temperatures, frost can form on the misted glasses. Thus with plastic windows it is necessary to handle with special care.
Sweating windows on the loggia: what to look for
The cause of the condensation on the windows is poor-quality installation or inconsistency of the profiles of plastic windows. It should be noted that it is not rational to produce glazing of a balcony or a loggia with single-compartment double-glazed windows. This is unambiguous, will cause humidity in the room. In this case, it is necessary to replace the single-chamber with a two- or three-chamber profile. At the same time, you do not need to change the entire window, only the profiles need to be changed.
. What should I look for when condensing on the loggia:
- Two-three-chamber glass unit is required;
- Good installation quality of windows;
But if the glazing was improperly installed, then it is necessary to contact the company that was engaged in the installation of glazing. And as long as the warranty period has not expired, fix the marriage in work.
Reasons: the windows on the balcony misted up, what to do( video)
In conclusion, it should be noted that when windows are misted up, what to do with this, you will not understand right away. But the appearance of condensate depends on many reasons, as well as the solution of this problem. And the correct answer to this problem, like elimination, is best entrusted to specialists.
