In the National Energy Museum, a black inflatable jacket acts as a thermal blanket which reflects the position of the interior domes in the geometric pattern generated by the necessary fragmentation of the surface. This discontinuous chamber, subject to overpressure, consists of two successive silicon skins reinforced with bulk-tinted fibreglass and pattern of transparent apertures, with outer skin made from a composite fluoride film which at the same time insulates and closes off the interior rooms.
