<p>The element has two parallel glass surfaces (1.1, 2.1) arranged at a distance from each other. Upper and lower frame sections are parallely processed on a plate wheel. Channels for air flow are guided over the sections. A ventilator module is arranged in a space between the surfaces. An electrically operated ventilator is enclosed in the module extending along a horizontal direction over a section width. The channels are selectively opened and/or closed by the sections between building exterior, building interior and space between glass surfaces.</p> |
