1. A multiple glazed window having two parallel panes of glass spaced apart to leave an air space between the panes with peripheries of the two panes being sealed with a sealant strip to close the air space, said sealant including an adsorbent therein, said adsorbent comprising a zeolite, having pores with apertures large enough to permit entry of oxygen and nitrogen molecules through said pore apertures, which is treated with a paraffinic, naphthenic or aromatic oil and outgassed under heat or under heat and vacuum to render the zeolite permeable to water vapor and essentially impermeable to nitrogen and oxygen molecules.
