ABSTRACT:
A window construction has at least two window- and/or wall-forming sections mounted in series on a common, stationary top profile member of which at least one first type of section is pivotably suspended about an upper horizontal axis for swinging from a closed position to an airing position and vice-versa and a second type of section is either similarly pivotably suspended or stationarily mounted on said member. The top profile member has two separate grooves, one for each of the types of section, which enables the first type of section to be also longitudinally displaceable relative to the section of the second type and independently of any remaining sections. Each section forms exclusively on the inwardly directed side thereof a sealing abutment against its respective stationary packing arrangement. The packing arrangement for the first type of section is arranged approximately flush with the outwardly directed side of the second type of section.
