WARM GLAZING:

With good glazing, balconies and loggias can become an integral part of the home. This part of the flat can be economically equipped with cold glazing. Lightweight aluminium profiles with single-glazed windows are ideal.
  If you want to protect your balcony from rain and dust from the street, but are not prepared to spend a lot of money, cold glazing is the ideal option. This involves installing aluminium profiles with classic 4-5 mm thick glazing or light insulating single glazing. 
  Due to its low thermal insulation properties, this type of glazing is suitable for balconies that are separated from the living space of the flat by a partition wall.
