Abstract: A glazing material for the selected admittance, absorption and reflection of radiant solar energy consists of two series of planar members contiguously and alternately disposed along a common plane in an angled relation to each other, which members define a transparent zone for the admittance therethrough of radiant solar energy and an opaque zone whereby solar energy contacting one side of the opaque zone is absorbed and radiant solar energy contacting the opposite side thereof is reflected. Dual glazed embodiments of the invention which may provide one or more insulating air pockets are also described.

Abstract: A combined solar heating and insulating apparatus for use on existing buildings or in new construction. The apparatus is inexpensive to manufacture and provides for auxiliary solar heating during the day and insulation during the night, both of which result in a savings in fuel and increased efficiency of the standard heating system of the building. The apparatus takes the form of panels which can be affixed to existing vertical southern walls with little or no modification, thus allowing for the use of solar energy without expensive physical modifications to the building.
