Abstract
A system and method for controlling light shading and thermal insulation in a light transmissive structure is disclosed. An array of adjacently-positioned, inflatable first tubes is provided, each of the first tubes being inflatable to abut an inflated adjacent first tube. Each of an array of inflatable second tubes is nested within, and inflatable independent of one of the first tubes. Each of the second tubes is connected to one of the first tubes such that when not inflated, each of the second tubes is flattened within the one of the first tubes. When inflated, each of the second tubes abut an inflated adjacent second tube via first tubes. The first tubes are preferably clear, while the second tubes are made of a reflective material.
