ABSTRACT:
An inflatable storm window is disclosed which is adapted to be positioned within a window frame to both provide insulation and prevent air leakage around the regular window sash. The inflatable storm window comprises a continuous hollow outer portion of tubular cross section formed from a pliable and expandable plastic. A transparent sheet of film is peripherally attached to the inner edge of the continuous hollow outer portion. Installation in the window frame is accomplished by inflating the hollow outer portion through a valve contained in the tubular sidewall.
