As you know, there is nothing perfect. And with metal -plastic windows. With all their advantages (described by us here), they have their drawbacks. They are not so critical, but when choosing windows for repairing the apartment, you need to know about them.
Metal -plastic windows are not as much as 10 years ago today. But still this is far from a penny. And your comfort and service life will depend on the correct choice of windows and installers.
Humidity mode
As you could hear, plastic windows, unlike wooden, “do not breathe”. And therefore moisture remains indoors and a greenhouse effect occurs in the room.
To maintain normal humidity, we recommend that you do not forget to ventilate the room in which PVC windows are installed.
Another temperature regime
It happens that PVC is imported from abroad and may not be adapted to harsh Russian winters.
Mistress: PVC is polyvinyl chloride.
To insulate such windows, the number of cameras in the profile increases, the profile itself thickens, thicker seals are placed.
As a result, after installation, such a window is more massive and more expensive. We recommend that you turn the quality to the characteristics of the purchased windows. You need to know the operating temperatures and the number of cameras in the profile.
Damage to windows
If you accidentally damage plastic, then getting rid of traces is unlikely to work out. Remember that damage to the plastic profile on PVC windows is not subject to correction and remain on the surface the entire service life of the windows.
In wooden windows, damage and scratches can be painted over or disguised with varnish.
Heat – and sound insulation
If we compare the indicators of heat transfer and sound insulation in wood and plastic with the same thickness of the material, then the plastic in this comparison loses significantly.
Collect dust
In addition, the surface of plastic electrostatic. So, attracts dust. Therefore, try to wipe the window frames with a damp cloth at least once a week.
Try to trust the installation of windows only to professionals. When choosing windows, forget to read what a double -glazed window is in a PVC window. And also, what are the advantages of metal -plastic windows over ordinary.
