I suspect the detail you are refering to isn't a different material, but is a through drilling into the bottom of the sealed-unit glazing recess. There is a known problem where water creeps round the edge of the frame and becomes trapped in the bottom of this glazing recess. This can over a period of time work it way through the seal in the sealed unit and cause misting between the panes.
