Slopes — design features of wooden and plastic window structures, which, with inadequate insulation, become a significant source of cold for the room. With the onset of cold weather, they turn into dew points, because it is on them that the moisture available in the room settles in the form of condensate, which causes mold. Windows insulation — a procedure that allows you to eliminate air contact from the room with the surrounding external environment, which means prevent the formation of the fungus and cooling the room.
