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.
