Abstract: An improved thermal drapery construction to provide two thermally resistant air spaces behind a decorative drapery without increasing the bulk or stack when the drapery is pulled off the glass. The construction consists of hanging a three part thermal drapery consisting of a backing material with fibrous spacer and a material metallized on two sides from a wide tape that suspends the three part combination under a carrier on a retaining rod. The combination material is slightly thinner than the carrier so an air space is created between the thermal drapery and a decorative drapery that is attached to the opposite side of the same carrier. The air space between the two draperies is also increased by a recalculation of the spacing of the carrier fastening means on the headings of the two draperies.A critical feature of the thermal drapery is the means of assembly that makes it fold in regular reverse folds so that it enhances the appearance of the folds of the outer drapery.

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.
