A heat insulating window includes a pair of outer glass panes (10, 12) held apart by a spacing member (l6) and surounded by a frame. One frame member (26) serves as a dessicant consealing member which holds a removable dessicant cartridge (44). The dessicant cartridge is connected to a conduit system (42) providing gas communication to the air space between the glass panes (10, 12).
