The window comprises a frame structure and relative to the frame structure an openable, top-hung sash structure with an insulating pane (4) enchased between top, bottom and side members (5-7) of metal or plastic profiles. The insulating pane (4) is manufactured with dimensions corresponding to the exterior dimensions of the frame structure for direct abutment on a gasket (11- 13) fastened to the exterior edge surfaces (17-19) of the top, bottom and side members of the frame structure, and 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 (31) for providing a good heat transmission to border areas of the insulating pane (4). The frame structure may consist of wood profiles (23) connected in profiled mitre joints (24).

Cette fenêtre comprend un cadre, ainsi qu'en relation avec celui-ci un châssis suspendu par le dessus, pouvant s'ouvrir et pourvu d'un panneau isolant (4) enchâssé entre des éléments supérieur, inférieur et latéraux (5-7) de profilés métalliques ou en matières plastique. On a fabriqué le panneau isolant (4) en le dotant de dimensions correspondant aux dimensions extérieures de la structure de cadre, afin que ce panneau vienne buter directement sur un joint d'étanchéité (11-13) fixé sur les surfaces des bords extérieurs (17-19) des éléments supérieur, inférieur et latéraux du cadre, lesquels éléments sont réalisés dans un matériau à bonne isolation thermique et sont recouverts, sur le côté intérieur situé en face de la zone d'entrée de lumière de la fenêtre, d'un profilé de feuille métallique (31) destiné à apporter une bonne transmission de chaleur aux zones de bordure du panneau isolant (4). Ce cadre peut se composer de profilés en bois (23) auxquels on a relié des assemblages à onglet profilés (24).
