ABSTRACT:
An enclosure for a window or door having insulative extendable and retractable sheet members which includes a housing having insulated widewalls, an insulated bottom wall and an insulated top wall for securement to a building structure for encompassing a window or door with the enclosure. The enclosure includes an outer thin flexible sheet closure member mounted on a first spring-urged takeup roller mounted adjacent the top of said housing with the upper end connected to the first roller. Also included is an insulative sheet member including a first sheet member and a second sheet member spaced therefrom with insulative material mounted between the same. The insulative sheet member is connected at the upper end thereof to a second spring-urged roller mounted adjacent the first spring-urged roller. The lower ends of the outer thin flexible sheet closure member and the insulative sheet member are connected to a transverse bar with take-up and releasable flexible members connected to the transverse bar for raising and lowering the outer closure member and the insulative sheet member against the action of the spring-urged rollers. The side edges of the outer thin flexible sheet member and the side edges of the insulative sheet member operate in slots in the sidewalls of the housing for sealing engagement therewith.
