ABSTRACT:
This invention relates to dynamic devices for insulating wall surfaces and especially surfaces including a window. A self-inflating solar curtain may be 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 another enclosure requiring temperature control. The curtain comprises at least one double-walled, air-entraining envelope with vents at the bottom for enabling an inhaling or exhaling process which takes air into and expels air from the envelope as the curtain is heated or raised, respectively. The curtain may be wound upon and stowed on a roller driven by a motor or other suitable means. A comb-like structure separates the top of the air-entraining envelope to insure an internal spreading of the curtain all of the way up to its top. This spreading is most important for smaller curtains and for curtains made of a material which clings to itself responsive to static attraction.
