An improved desiccant package for use with double-glazed windows. The desiccant material is disposed in discrete islands of desiccant material, between a pair of elongate sheets of flexible material. The sheets are joined together to contain the desiccant within the joined sheets, and to prevent the desiccant from migrating away from the individual islands. Both sheets are impermeable to the desiccant, but at least one of the sheets is substantially permeable to moisture. The desiccant package is disposed within an elongate tubular spacing member for fitting between the two panes of a double-glazed window. The spacer member has a longitudinal side which faces the air space between the two panes of the double glazing, and this longitudinal side is perforated to allow the atmosphere inside the double glazing to communicate with the desiccant package within the spacer tube.

A double-glazed window assembly comprising: a pair of mutually spaced-apart window panes mounted in fixed relation; a hollow moisture permeable spacing tube laterally disposed between said panes; a desiccant package inserted in the length of said spacing tube; said desiccant package comprising a first elongate sheet of ductile airtight material; plural discrete indentations formed in one face of said first elongate sheet at intervals along the length of the first sheet; a quantity of desiccant disposed in said indentations; a second elongate sheet secured to said one face of said first sheet to form the desiccant package and enclosing each said indentation and the desiccant therein, so that the desiccant cannot migrate between indentations along the length of the desiccant package; and said second elongate sheet being substantially permeable to moisture but being impermeable to the desiccant, so that the desiccant is retained within the indentations, but moisture entering the spacing tube from between said panes of the double-glazed window can pass through the second sheet for adsorption by the desiccant.
