Plastic windows have long been almost an obligatory attribute of any house or apartment in our country. Given their durability, beauty and hygiene, there is nothing surprising in this.
But practically none of our compatriots knows which “behavior” is the norm for them, and which signs indicate production defects. For example, why do plastic windows fog up?
First reason
If there is fogging, then we immediately decided to blame the manufacturer or the installers themselves for everything. But in most cases, there is no fault.
As a rule, the reason is humidity. It happens that people are surprised at the “crying” windows on the battery under which they dry their clothes. This often happens in the kitchen, where the humidity rises sharply during cooking and the release of large amounts of water vapor.
How to avoid this phenomenon? Everything is simple - ventilation. If you often encounter such an annoying phenomenon, it is better to install a hood.
Second reason
In this case, everything is about the same. Why are plastic windows fogging in those apartments, the owners of which installed three- or even five-chamber packages, but did not think about ventilation at all? Housing in this case becomes almost completely sealed, so that all excess moisture is simply precipitated in the form of condensate.
What to do? The same as in the situation described above, by installing a hood or otherwise adjusting the ventilation.
Third situation
But why do plastic windows fog up if all of the above has nothing to do with you? It is possible that air convection is disturbed in your home. You think why the heating registers are installed directly under the window openings? This is done so that the flow of warm air rising from them warms up the window, preventing condensate from precipitating on a cold surface.
If something bothers him, then because of this, the plastic windows fog up. What to do in this case? Make sure that the air circulation in the room does not interfere, and if necessary, eliminate all interference found. In the most severe cases, shortening an excessively wide window sill or making several holes in it helps.
Still window defect
Unfortunately, occasionally there are situations when the “root of all evils” is, in fact, a congenital defect in a particular glass packet. To assert this for sure, it will be necessary to order technical expertise of the project. Most often, the only way out is to completely replace the problem window.
So why are fogging plastic windows? As you could find out in the course of reading our article, most often the cause is not some kind of defect during their assembly, but the reasons connected exclusively with your own premises.
First of all, it is always necessary to check the state of ventilation. In the houses of the old Soviet built in this matter there are big problems, so it would not be out of place to spend money on the normal implementation of the system.
That's all the main reasons why plastic windows fog up. What to do, you already know.
