ABSTRACT:
Instead of enclosing the space between a sky-light dome and a ceiling window by the usual custom-built box or shaft, the space is easily, economically and effectively enclosed by a section of large-diameter flexible tubing stretched between the dome and the window. The ends of the tubing section fit over short sleeves on or attached to the dome and the window, and can be fastened to the sleeves by cement and/or constrictable bands. The tubing is preferably formed of an outer plastic ply and an inner light-reflective aluminum-foil or an aluminized-plastic ply, which are adhesively laminated with a helically coiled spring-wire skeleton embedded therebetween.
