A multiple pane unit comprising a pair of sheets maintained in parallel, spaced-apart relationship to each other by a spacing and sealing assembly defining a substantially hermetically sealed, insulating airspace between the sheets. The spacing and sealing assembly includes inner and outer elements.

A multiple pane unit comprising a pair of sheets maintained in parallel, spaced-apart relationship to each other by a spacing and sealing assembly defining a substantially hermetically sealed, insulating airspace between the sheets. The spacing and sealing assembly includes inner and outer elements. The outer element is adhered to the marginal periphery of the inner, facing surfaces of the sheets. The inner element is self-adhered to the marginal periphery of the inner, facing surfaces of the sheets in communication with the airspace and in juxtaposition to the outer element. Both the inner and outer elements have at least minimum adhesive structural bonding strength. The inner element preferably comprises a moisture vapor transmittable matrix material having a desiccant material dispersed therein, thereby ensuring communication between the desiccant and the airspace sufficient to maintain dryness of the airspace. The outer element is preferably composed of a substantially moisture-impervious material, to thereby prevent saturation of the desiccant and ensure the weathertight integrity or hermetic sealing of the unit.
