Glazing element, in particular for facing building facades

A method of controlling the flow of radiation through a multiple paned structure, comprising:

• providing two panes at a distance from one another to define an intermediate space therebetween;
• supplying a gas atmosphere to said intermediate space;
• applying a reactive layer on a surface of at least one of said panes which faces said intermediate space;
• applying a catalytic layer on said reactive layer, said catalytic layer activating said reactive layer depending on a composition of said gas atmosphere to change at least one of optical and electrical properties of said reactive layer;
• and
• varying the composition of said gas atmosphere.

A multiple pane structure with variable radiation transmissivity, comprising:

• two panes arranged at a distance from each other to define an intermediate space therebetween;
• a reactive layer disposed on a surface of at least one of said panes, said surface facing said intermediate space;
• a catalytic layer disposed on said reactive layer;
• and
• a gas to be supplied to said intermediate space, a composition of said gas being variable, said catalytic layer activating said reactive layer in response to the composition of said gas to vary the radiation transmissivity of said reactive layer.

A method of varying a radiation transmissivity of a multiple pane structure, comprising:

• providing two panes arranged at a distance from each other to define an intermediate space therebetween, a reactive layer being disposed on a surface of at least one of said panes, said surface facing said intermediate space, a catalytic layer being disposed on said reactive layer;
• supplying a gas to said intermediate space, a composition of said gas being variable, said catalytic layer activating said reactive layer in response to the composition of said gas to vary the radiation transmissivity of said reactive layer;
• and
• varying said composition of said gas.
