Patent attributes
An insulated glass unit having: an outer lite, an inner lite, and a shock absorbing spacer bar disposed between perimeter portions of the inner and outer lite, forming a cavity, the spacer bar having: an inner housing with a plurality of desiccant ports disposed between an internal desiccant chamber and the cavity; a desiccant encased within the desiccant chamber; a flexible outer housing in which the inner housing is nested; and a perimeter guard disposed on the outer surface of the spacer bar, said perimeter guard being configured to attach the spacer bar to each lite. The spacer bar is configured to be highly crush resistant, thus preventing the either lite from being dislodged during a forced entry attempt. The desiccant ports expose the desiccant to the cavity for humidity maintenance within said cavity. An additional lite and spacer bar may be implemented to form a three lite IGU.
