Facade system of metal sections

Abstract

A facade system of metal sections which receive plate-shaped elements between them such as fixed glazing, sashes, panels or the like which are each provided with an encircling auxiliary frame located exclusively on the room side and connected by releasable connecting means to main frames having means for attachment to a structure, in which: (a) the facade system consists of several separately formed and individually manipulable main frames into each of which at least one auxiliary frame is inserted; (b) on the room side, the main and auxiliary frames form a flat reveal extending perpendicularly to the facade plane; (c) inside this flat reveal, the main and auxiliary frames are spaced a clearance distance from one another which is closed air-tight by an encircling first seal, which simultaneously covers the releasable connecting means between the main and auxiliary frames; (d) the main frames are air-tightly connected on the room side to the respectively adjacent main frames by a second seal; and (e) the weather seams between all plate-shaped elements are each closed air-tight by a third seal.
