ABSTRACT:
A thermally protective drapery construction comprises retaining rod means and inner and outer panels of drapery material arranged in suspended, separated relationship on the retaining rod means. The separated drapery panels are supported in a manner such that a thermally resistant critical air spacing is provided and extends between the panels and at a substantially uniform value. In the case of folds of respective inner and outer panels which are moved toward and away from one another along the retaining rod means, uniformity of the spacing is maintained during such movement.
The critical air spacing consists of a thermally resistant air space provided by locating the panels apart from one another a distance lying in a range of from 0.25 inches up to approximately 0.5 inches. Such a spacing between upper portions of the inner and outer panels of drapery material is achieved by securing together the panels with snap fastening carriers on the retaining rod and snap fastening tapes secured to the panels and attached to the carriers in spaced apart relation. Intermediate and lower portions of the inner panel also have fastened thereto fibrous separator means. The separator means may be of a thickness co-responding to the above-noted critical air spacing and extend into contact with the outer panel. The retainer rod means includes a heat cap attached by bracket means to a wall surface and located in closely spaced relation to upper edges of the drapery folds to constitute an air baffle which is maintained in effect when the drapery folds are opened and closed. The inner panel has a vertical edge seal which is also maintained when the inner and outer drapery folds are opened and closed and which permits access to a cord and pulley located between the panels without breaking the edge seal.
