ABSTRACT:
A novel sealing and spacing unit for multiple glazed windows, and multiple glazed windows employing such a sealing and spacing unit, are disclosed. The sealing and spacing unit comprises a flexible, moisture-impervious base such as a strip of aluminum foil. Disposed on the base in a lengthwise manner is an elongated, flexible, dehydrator strip which comprises a particulate desiccant such as a crystalline zeolite dispersed throughout a moisture-permeable, elastic, polymeric matrix, such as an ethylene-ethyl acrylate copolymer. The dehydrator strip is secured to the base by a thin layer of an adhesive such as an ethylene acrylic acid copolymer hot melt adhesive. Also disposed on the base in a lengthwise manner are two strips of a cold flowable, moisture resistant, mastic, sealant composition. The strips are preferably spaced slightly apart from, and are positioned on both sides of the adhesively secured dehydrator strip. Preferably, the cold flowable, mastic, sealant composition is an admixture of polybutene and two different molecular weight polyisobutylenes.
