Abstract
A square skylight panel is vacuum-formed of light transmitting sheet plastic and has a lower peripheral flange which projects under roof shingles. The skylight panel covers a one-piece upper coupler member which is vacuum-formed of light transmitting sheet plastic and has an upper flange projecting under the skylight panel flange. A flexible and collapsible cylindrical tube has an upper end portion surrounding a lower wall portion of the upper coupler member and a lower end portion surrounding an upper wall portion of a similarly formed lower coupler member having a bottom flange received within a square frame attached to a ceiling and supporting a light diffusing ceiling panel. The skylight panel, upper and lower coupler members and ceiling panel define three dead air chambers providing for high thermal insulation, and the upper coupler member provides natural light into the attic between the roof and ceiling.
