Abstract
Abstract A storm window structure in which the face of a building structure and the edges of the associated storm window sashes are provided with members which interact magnetically to hold the sashes in position against the casing. One member is permanently magnetic and the other is ferromagnetic. Preferably the former is supplied in the form of a profile having grooves into which the pane may be inserted and cemented.
