Abstract
Abstract A thermal drapery construction including first and second metalized fabric panels, a third panel of high loft, low density, randomly oriented fibers disposed between the first and second panels and a thermal drapery liner located adjacent the metalized surface of the second fabric panel. The panels and liner are typically bound together along their aligned outer edges to form a highly insulating liner assembly. The liner assembly is lightweight, flexible, drapes well and can be used in conjunction with a decorative drapery fabric opposite the metalized surface of the first fabric panel to form pleated hung draperies. Adhesive means, such as magnetic strips, can be attached to the outer surface of the liner to seal against heat loss between the liner assembly and the window.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
154 words
A thermal drapery construction suitable for use in making hung draperies comprising: a decorative flexible drapery fabric; and a flexible liner assembly means, attached to said drapery fabric, for thermally lining said drapery fabric comprising: a first fabric panel having a first metalized surface facing an inside direction and a second surface facing an outside direction; a second fabric panel disposed adjacent the first panel and having a first metalized surface facing the outside direction and a second surface facing the inside direction and the second surface of the first panel; a third relatively thick, low density flexible panel situated between the second surfaces of the first and second panels, said third panel having a low density to form a dead air space between said first and second panels; said first, second and third panels having aligned outer edges; and means for binding the aligned outer edges of said first, second and third panels.
Claim 2
Dependent Claim
154 words
A thermal drapery construction suitable for use in making hung draperies comprising: a decorative flexible drapery fabric; and a flexible liner assembly means, attached to said drapery fabric, for thermally lining said drapery fabric comprising: a first fabric panel having a first metalized surface facing an inside direction and a second surface facing an outside direction; a second fabric panel disposed adjacent the first panel and having a first metalized surface facing the outside direction and a second surface facing the inside direction and the second surface of the first panel; a third relatively thick, low density flexible panel situated between the second surfaces of the first and second panels, said third panel having a low density to form a dead air space between said first and second panels; said first, second and third panels having aligned outer edges; and means for binding the aligned outer edges of said first, second and third panels.
Claim 3
Dependent Claim
22 words
The drapery construction of claim 1 further comprising a fabric liner disposed adjacent the first metalized side of the second fabric panel.
Claim 4
Dependent Claim
25 words
The drapery construction of claim 1 wherein said first and second panels are porous to permit moisture evaporation from between said first and second panels.
Claim 5
Dependent Claim
19 words
The drapery construction of claim 3 wherein said third panel comprises high loft non-woven battings of randomly dispersed fibers.
Claim 6
Dependent Claim
15 words
The drapery construction of claim 4 wherein said third panel is about 7-14 mm thick.
Claim 7
Dependent Claim
19 words
The drapery construction of claim 5 wherein the density of said third panel is about 0.014 g/cm 3 .
Claim 8
Dependent Claim
33 words
The drapery construction of claim 1 further comprising attachment means for securing the outer edges of the liner assembly to a surface to retard heat flow between the liner assembly and said surface.
Claim 9
Dependent Claim
25 words
The thermal drapery construction of claim 1 wherein said binding means binds the aligned outer edges leaving the remainder of the liner assembly substantially unbound.
Claim 10
Dependent Claim
134 words
A thermal drapery liner assembly for use in combination with a decorative drapery fabric comprising: first and second fabric panels each having a metalized surface, said first and second panels opposed and arranged parallel to one another with their respective metalized surfaces facing outwardly in opposite directions, said first and second panels being porous to permit evaporation of moisture from between the first and second panels; a third panel of high loft, low density randomly oriented fibers disposed between the first and second panels; a fabric liner located adjacent the metalized surface of the second panel, the respective edges of said panel and liner being generally aligned; and means for binding together the first, second and third panels and the liner along their edges leaving the remainder of the panels and liner substantially unconnected.
Claim 11
Dependent Claim
134 words
