Abstract
A window blind for use between double panes of glass which has an aperture in one pane of glass. The blind can be raised, lowered and tilted while maintaining the window seal. The blind includes a headrail, slats, a hollow screw with longitudinal screw channels. The hollow screw passes a headrail aperture and a glass aperture from inside the headrail to outside thus being threaded into a screw duct. At least one lift cord and a tilt control cord separately pass through the longitudinal screw channels thereby providing an external way to control the window blind.
