Abstract
An improved multiple glazed unit including a pair of glass sheets maintained in spaced-apart relationship to each other by a spacer element to provide an airspace therebetween and a sealing element to hermetically seal the airspace, is characterized by a spacer element containing a dehydrating material and an unplasticized polymeric material which is the reaction product of a polyisocyanate and an active hydrogen containing material; and a sealing element containing an unplasticized polymeric material which is the reaction product of a polyisocyanate and an active hydrogen containing material; the polymeric material of the spacer element having a moisture vapor transmission rating which is greater than that of the polymeric material of the sealing element.
