Abstract
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. The means of assembly also allows the material to be uniformly opaque. Additional improvements have been made to the heat-cap and support brackets to facilitate installation of the heat cap and retainer rod or rods. The thermal drapery has a design feature that allows a sheer curtain to be hung behind the drapery with no danger of the outer drapery crushing the inner when the outer drapery is opened and closed.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
128 words
A thermal drapery system comprising: a carrier assembly; an outer drapery secured to one side of the carrier assembly; a thermal drapery secured to the carrier assembly on a side opposite the outer drapery, the thermal drapery comprising a fabric secured to the carrier, a fibrous spacer secured to the fabric between the fabric and a heat reflective material metallized on two sides that is secured to the fibrous spacer with a patterned adhesive arranged in spaced parallel lines such that a first reflective space is formed by the fibrous spacer between the metallized material and the fabric and a second reflective space is formed by a spacing between the metallized material and the outer drapery, the thermal drapery system being periodically foldable along the spaced parallel lines.
Claim 2
Dependent Claim
128 words
A thermal drapery system comprising: a carrier assembly; an outer drapery secured to one side of the carrier assembly; a thermal drapery secured to the carrier assembly on a side opposite the outer drapery, the thermal drapery comprising a fabric secured to the carrier, a fibrous spacer secured to the fabric between the fabric and a heat reflective material metallized on two sides that is secured to the fibrous spacer with a patterned adhesive arranged in spaced parallel lines such that a first reflective space is formed by the fibrous spacer between the metallized material and the fabric and a second reflective space is formed by a spacing between the metallized material and the outer drapery, the thermal drapery system being periodically foldable along the spaced parallel lines.
