DESCRIPTION:
BRIEF SUMMARY
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 enchased between top, bottom and side members of metal or plastic profiles and manufactured with dimensions corresponding to the exterior dimensions of the frame structure for direct abutment on a gasket fastened to the exterior edge surfaces of the top, bottom and side members of the frame structure.
In respect of windows of this type, which are i.a. known from DK patent no. 74,858, it is a general problem to obtain sufficient tightness and insulation 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 has been solved in many in themselves satisfactory, but expensive and complicated ways.
The object of the invention is to provide a window of the type mentioned by way of introduction, which is both easy and inexpensive to manufacture, but which at the same time meets the demands in respect of insulating properties and of avoiding condensation, which are made to a window to be used in occupied areas.
This object is met according to the invention by a window which is characterized in that the top, bottom and side members of the frame structure are made from a thermally well insulating material and on the interior side facing the light admitting area of the window covered by metal sheet profiles for providing a good heat transmission to border areas of the insulating pane.
By making the sealing between the sash and the frame in this way, instead of the traditional way of placing a weather strip in a groove in the frame or the sash, the demands made on the manufacture of the sash are smaller and the formation of thermal bridges is avoided. In combination with the well-insulated frame and the heat transmitting profiles, such a window will under normal conditions be substantially free of condensation.
The top, bottom and side members of the frame structure preferably comprise wood profiles connected in profiled mitre joints, which, in addition to making the mounting of the window frame structure simple, gives a further improved insulation, the badly insulating end faces of the wood profiles being covered.
In a material-saving embodiment the wood profiles have substantially parallelogram-shaped cross-section, said exterior edge surfaces being positioned in a common plane, with which the adjacent opposite side faces of the profile cross-section form an angle of 95 to 140.degree..
A preferred embodiment of the invention is characterized in that the thickness of the wood profiles is comparatively small and that for improving the heat insulating properties additional insulating elements of a good heat-insulating material area are retained to the side of the profile cross-section which is intended to form the interior side for the top, bottom and side members of the frame structure.
In an embodiment which has been developed with a particular view to reusing the material of the window, the wood profiles in the top, bottom and side members of the frame structure are releasably connected with said heat-transmitting metal sheet profiles and additional insulating elements, if any, whereby the window, when dismounted, will be easy to disassemble.
Further embodiments of the invention will appear from the remaining independent claims, which have not been mentioned above.
The invention will be explained in the following with reference to an embodiment as shown in the ac
