The use of plastic profiles to insert glasses of balconies and loggias is the most common solution. Such glazing, unlike aluminum, will make it possible to create heat on the balcony in any season. When carrying out glazing work, it is immediately necessary to insulate the base of the floor of the balcony, as well as the walls. Due to the fact that the windows are placed in a quarter, the maximum thermal insulation effect will create. When installing plastic profiles, their size must be adjusted for the opening. In view of the fact that there are no standard sizes, an individual selection is carried out for each individual case, and this imposes a special responsibility for specialists to ensure the strength of the structure.
