The disadvantages of plastic windows. The main disadvantage of plastic structures is that they are harmful to human health. The fact is that plastic contains dangerous heavy metals, cadmium and lead.
Even large manufacturers cannot make the design completely environmentally friendly.
The downside of PVC windows is high tightness. Due to the fact that plastic does not allow fresh air to get into the room, a “greenhouse effect” may occur, the room will be stuffy in the room. Condensation freezing in winter will form on the glasses. To avoid this, it is necessary to ventilate the room many times.
Another drawback is a difficult repair. If scratches appear on a plastic profile or it is almost impossible to remove their dents. Cracking glass can only be changed along with a double -glazed window. Attract dust, since the window made of plastic is electro-statical.
PVC windows have a large expansion coefficient. At high temperatures, they “expand”, at low “compressed”, which can lead to cracks on the profile finishing work in Moscow.
Constructions made of plastic require proper professional installation.
High -quality plastic windows are quite expensive.
