<p>A multiple pane insulated panel unit for a window has an inner filamentary seal and an outer seal. The inner seal contains desiccant material throughout its cross-section with the concentration greater in the inner portion thereof than in the outer portion thereof. The concentration may progressively change. The inner seal may comprise a plurality of layers with the concentration increasing from the outer layer to the inner layer. Particular concentrations are given. Molecular sieves having absorption pores of about 4.ANG. and 10.ANG. may be employed, and the concentration of the 10.ANG. pore sieves may be greater in the outer portion than in the inner portion of the inner seal.</p> |
