Abstract
A multiple pane window has an inner filamentary seal and an outer seal. The inner seal contains desiccant material whose concentration is greater in the inner portion thereof than in the outer portion thereof. The concentration may change progressively. The inner seal may comprise a plurality of layers with the concentration constant in each layer. Particular concentrations are given. Molecular sieves having absorption pores of about 4A and 10A may be employed, and the concentration of the 10A pore sieves may be greater in the outer portion than in the inner portion of the inner seal.
