Abstract: A vent or baffle assembly may be used between the edge of a window and the edge of a recess along which the window can reciprocate, or may be used adjacent a doorway. The vent assembly may include longitudinally extending members, and spacing members, or blocks. The longitudinally extending members and the blocks may be assembly to form a unit having a tortuous internal passageway. The longitudinally extending members may provide structural sturdiness. Sound deadening materials may be applied along a portion or all of the passageway. The longitudinally extending members may be of the same profile, and may nest together in a symmetrical fashion.
