Abstract
Abstract Resilient glazing gaskets are utilized to mount spaced glass plates to inwardly directed glazing fins within a frame made up of joined elements. Continuous beads of sealant applied to the outside of the fins form an airtight seal between the gaskets and the inner surface of the frame. Beads of sealant applied between the fins to the inside of the frame where its elements are joined are connected with the continuous beads through holes provided in the fins adjacent the joints, thereby hermetically sealing the air space between the glass plates. The sealant is therefore continuous along the twelve edges of a three-dimensional rectangular box-like figure so as to completely seal the volume between the spaced glass plates. In an alternate embodiment, a gasket is used along the outer periphery of one of the glass plates. The second glass plate is mounted adjacent the fin on one side of the frame and sealant is positioned about its periphery to create the 12-sided sealing figure. Inlet and outlet ports at the top and bottom of the unit furnish means for conveniently charging and replenishing spaces provided between the fins with desiccant materials.
