Confuse them

When choosing plastic windows, pay attention to the double -glazed windows, since it is they who occupy most of the structure and, accordingly, it is through them that you will look at the street. Double -glazed windows also have cameras, but you should not confuse them with cameras in the profile. Double -glazed windows can be single -chamber or two -chamber. Single -chamber are double -glazed windows consisting of two glasses, and two -chamber — of three, that is, such glasses form two cameras between themselves. Of course, the more such cameras, the warmer and quieter in your apartment.
