There is a possibility to protect the balcony with a glazing. So called balcony glazings are important for certain areas that are heavily influenced by weather or noise. Assemblers, which create designs and static evaluation for the balcony glazing, are necessary to integrate the glazing conform with regulations and laws. Because if the glazing is assembled in the wrong way, parts could fall off and damage property or persons.
Unlike a terrace, balconies and also their balustrade need a static evaluation, so they don't take damage over time and can permanentely hold their visitors.
