There exists the potential to install a Solatube from the roof line (sloped or flat roof) down through the room below to the next level living space. In some cases the building plans will incorporate a framed in vertical shaft to house the Solatube to line up with the dark area below. The framed in shaft will line up directly with the floor joists below and the ceiling/roof trusses above to permit the vertical Solatube. Some of these installations yield a 10ft - 17ft long tube shaft depending on the height of the attic space above the framed in shaft. Usually this shaft ends up located within a closet, hallway or pantry wall and is dry walled upon completion. There is a small amount of light loss within this extra length, however the end result is sensational compared to the previously pitch black room below.
