This invention relates to dynamic devices for insulating wall surfaces and especially surfaces including a window. A self-inflating solar curtain is automatically raised and lowered in response to the direction of heat flow into or out of a confined space within which the temperature is to be controlled. This confined space could be a solar collector, a room in a house, or other enclosure requiring temperature control. The curtain comprises at least one double-walled air-entraining envelope with vents for enabling an inhaling or exhaling process which takes air into and expells air from the envelope as the curtain is heated or raised, respectively. The curtain can be wound upon and stowed on a roller driven by a motor or other suitable means which may be controlled automatically by sensors which detect and respond to temperature differentials on opposite sides of the curtain.
