For generations, homeowners have clearly thought of windows when they heard the term glazing. Single, double and in the meantime also three or four times glazed windows - the properties of the glass however have changed dramatically. Noise and temperature insulation are features and also - if desired - opacity just by pressing a button. Now glass is increasingly becoming a facade, as a solar panel, as insulation or as a photovoltaic system. For Architects this development is really fantastic.
