Why do plastic windows sweat inside the house

Eurowindows have long come into vogue as practical and warm substitutes for ordinary wooden window frames. They are quick to install, have several double-glazed windows that help contain strong temperature changes, and the opening mechanism allows you to ventilate the room at any time of the year. However many owners of such structures are faced with a problem their fogging in winter. Explaining why the plastic windows are sweating, specialists call the installation with errors the main reason.

Replacing old windows

Typically, the installation of plastic double-glazed windows in houses and apartments is carried out on the site of old frames. Wooden beams are removed from the wall., and in their place new metal-plastic constructions are mounted.

This usually consists of the problem, which subsequently results in fogging and leakage of double-glazed windows. It is possible that low-quality products or insufficient ventilation can also cause smudges.

So, the main reasons for fogging plastic windows are:

• defective or poor-quality hardware;
• lack of ventilation or poor heating in the room;
• unprofessional or poor-quality installation in violation of building codes.

Options for eliminating fogging

What to do if the plastic windows sweat heavily will depend on the cause of the problem. When a low-quality double-glazed window is installed, it can be replaced with another, while the frame can be left unchanged. It often happens that the glass is sweating inside. This may be due to poor product quality or lack of absorbent material in a special chamber between the bags.

If installation errors were made and the installation standards were not followed, the glass surface can also fog up for almost no reason. It would be more expedient to hire another brigade, which will rearrange the windows, taking into account all the nuances of the structure.

Putting a new frame in place of the old one is a common mistake. Since the plastic structure has a smaller thickness than the wooden one, it should deepen more during installation. Due to this, wind flows passing outside cannot additionally cool the glass surface, which will contribute to a lower temperature difference from inside and outside and, as a result, prevent heavy sweating.

Inadequate ventilation most often occurs. when the product is defective or improperly installed. During the installation of the window structure, there must be a certain space between the wall of the house and the side of the frame, which is blown by the foam.

After one day, you can plaster the slopes, and the surface should subsequently be whitened or painted.

Trying to understand why the plastic windows in the house are sweating, you need to pay attention to the heating in the rooms. If it is insufficient, you should think about adding heating points under the glass, which flows and fogs up.
