A self-adhesive quilted polyester sheet that sticks to flat window glass to cut drafts and slow heat loss in winter. It trims to size with no tools, wipes clean, and resists water. It suits renters and owners in older homes with single-glazed or drafty windows who want a cheap, removable fix. Against rigid acrylic storm panels or secondary glazing, it insulates less and blocks the view, but it installs in minutes and comes off without damage. Buyers rate it well, though some find the adhesive weak on cold glass and the quilting dulls daylight.
