ABSTRACT:
A multifunction solar window and venetian blind is disclosed which is both functional and decorative. The disclosed structure includes a combination of a double-glazed window or door provided with a plurality of solar thermal energy absorbing slats rotatably installed intermediate the glass panes of said window. The slats have at least one surface constructed for absorbing solar thermal energy, and may be rotated to face either surface toward the exterior of dwelling in which the window may be installed. A plurality of apertures through the frame above and below the glass surfaces may be selectively opened and closed, in desired combinations, to provide open pathways through which air may flow into and out of the space between the glass surfaces. The slats in this space may transfer their heat to this air which may, by selective opening of said apertures, be used to heat or ventilate the interior of the dwelling. Decorative strips are provided on the slats to enhance solar efficiency and to provide a plurality of decorative patterns.
