ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a window, in particular for mounting in an inclined roof surface, comprising a frame structure with top, bottom and side members and a relative to the frame structure openable, top-hung sash structure with an insulating pane encased between top, bottom and side members of metal or plastic profiles, the sash profiles being metal sheet profiles with substantially L-shaped cross-section and small wall thickness, and a resilient gasket profile being secured to the outwards facing edge surfaces of the top, bottom and side members of the frame structure as abutment for the interior side of the insulating pane.
Windows of this type are for example, known from DK patent No. 74858 and U.S. Pat. No. 4,776,141. In such windows it is a general problem to obtain sufficient tightness relative to the room inside, in particular if for reasons of appearance, when the windows are for instance to be used in protected buildings, traditional building materials cannot be used.
Windows of this simple design are thus, first and foremost, suited for more or less uninhabited areas, for instance, ceilings or outhouses. In living-quarters, condensation will, however, easily form on the interior side of the insulating pane, when the cold outside air gets in contact with the hot and humid indoor air. Condensation is a well-known problem within this field and this problem has been solved in many satisfactory, but expensive and complicated
SUMMARY OF THE INVENTION
The object of the invention is to improve a window of the type, which is both easy and inexpensive to manufacture, but which at the same time, meets the demands made on a window, and which is to be used in occupied areas.
This object is met according to the invention by a window which is characterized in that the insulating pane is manufactured with such dimensions that its edges, when the window is closed, are placed substantially in flush with the exterior sides of the frame structure, that the sash profiles comprise a comparatively narrow wall portion in abutment on an edge portion of the exterior side of the insulating pane and a second wall portion connected therewith through a rectangular corner and abutting an edge surface of the insulating pane, said second wall portion overlapping, in the closed position of the window, the exterior side of the frame member lying behind, and in that the insulating pane is secured in said wall portions of the sash profiles solely by adhesive sealing.
In addition to the desired simple manufacture it is obtained that by manufacturing the insulating pane with such dimensions in combination with the positioning of the gasket profile on the outwards facing edge surfaces of the frame structure, smaller demands are made on the design of the sash, and the formation of cold bridges is avoided, whereby the tendency of condensation in the window is reduced. Furthermore, the design of the sash profiles provides a good weather-proof protection of the interior parts of the window.
The sash profiles are preferably mutually connected by welding, and the adhesive sealing of the insulating pane is preferably made by a silicone adhesive, which results in a simple and inexpensive manufacture.
The design of the sash construction makes it possible to make the top hinge of the window integral with the sash profile.
