An apparatus for regulating the transmission of energy through an energy transmissive structure having at least one energy transmissive panel comprising in combination at least one elongated support adjacent to the energy transmissive panel of the energy transmissive structure. A polymer bag made of polyethylene terephthalate encapsulates the elongated support which allows the polymer bag to be inflated or deflated around the elongated support. The outer surface of the polymer bag has a reflective coating for reflecting energy through the energy transmissive structure. There is at least one elongated weight attached to the polymer bag to ensure that the polymer bag is maintained in its optimum position. There is at least one air distribution header attached to the elongated support to inflate or deflate the polymer bag. In an inflated state, the polymer bag blocks the transmission of energy and in a deflated state, the polymer bay allows the transmission of energy through the transmission energy panel of the energy transmissive structure. |
