Why do plastic windows fog up and how to avoid it?

Plastic windows have long been almost an indispensable 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 do not know what "behavior" for them is the norm, and what signs indicate industrial defects. For example, why do plastic windows fog up?

Cause one

If there is a fogging, then we immediately accuse the whole of the manufacturer or installers themselves. But in most cases, there is no guilt here.

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 underwear. This often happens in the kitchen, where the air humidity rises sharply during cooking and the allocation of a large amount of water vapor.

How to avoid this phenomenon? It's simple - ventilation. If you often encounter such an annoying phenomenon, it is better to install the hood.

Reason two

In this case, everything is about the same. Why do plastic windows fog in those apartments whose owners installed three- or even five-chamber packages, but did not think at all about ventilation? Housing in this case becomes almost completely airtight, so that all the excess moisture simply precipitates in the form of condensate.

What to do? The same as in the situation described above, setting the hood or otherwise adjusting the ventilation.

Third situation

But why do plastic windows get fogged up, if all the above-mentioned has nothing to do with you? Probably, in your habitation air convection is broken. Do you think why heating registers are installed right under the window apertures? This is done so that the warm air rising from them warms the window, preventing condensation from settling on the cold surface.

If something hinders him, then because of this misting up the plastic windows. What to do in this case? Make sure that the circulation of air currents in the room does not interfere, and if necessary, eliminate all detected interference. In the most severe cases, it helps to shorten an unnecessarily wide window sill, or make several holes in it.

And yet the defect of the window

Unfortunately, from time to time there are situations where the "root of all evil" is in fact the inherent defect of a particular double-glazed unit. To argue this for sure, will have to order experts a technical examination of the project. Most often, the only solution is to completely replace the problem window.

So why do plastic windows fog up? As you could find out in the process of reading our article, most often the cause is not some defect in their assembly, but the reasons associated solely with your own room.

First of all, always check the ventilation status. In the houses of the old Soviet construction in this issue there are big problems, so it's not superfluous to spend money on the normal implementation of the system.

That's all the main reasons that make plastic windows fog up. You already know what to do.
