Weep and sealing window system

摘要

A divided light window has a frame defining a plurality of light openings each of which receive an insulated glass unit. The frame has vertical and horizontal weep grooves cut therein to allow moisture to drain from the window, and a sealing system allows substantial shifting of the glass unit and does not interfere with the weep grooves. The insulated window unit is provided with a tape dam about its perimeter that is disposed opposite the weep grooves to prevent glazing material comprising the sealing system from entering and obstructing the weep grooves.
