The insulated window construction is characterized in having a substantially uniform heat transition coefficient. The uniformity of the heat transition coefficient is obtained by increasing the distance between the window panes and the heat resistance in the edge region of the window is matched to that in the region of the window area which is undisturbed by the edge. The edge region is formed by a frame which has a pair of separate metallic frame members which are joined together and spaced apart by non-metallic webs so as to define an insulation path of at least 0.8 times the clearance between the panes.

A heat insulation window comprising a pair of outer panes defining an air space therebetween and spaced from each other by a clearance of at least 50 millimeters; a non-metallic air-permeable peripheral spacer spacing said panes from each other; at least one transparent partition spaced between said panes; a selectively reflective coating on at least one of said partition and said panes; a frame mounting said panes, said partition and said spacer therein, said frame including pair of separate lateral metallic frame members and at least one thermally insulating web joining said frame members together circumferentially in shear resistant relation to form a closed rigid unit, said frame members being spaced from each other to define an insulation path of at least 0.8 times said clearance between said panes and said web having a thermal expansion at least approximately equal to said frame members; and a drying chamber for a desiccant disposed between said air space and an exterior of the window.
