Panel structure for blocking windows

Abstract

A panel structure for use in blocking glass panes against the passage of heat and cold. In one form the structure comprises first and second rigid foam panel sections joined together by a flexible sheet. The ends of the panels are exposed underneath the sheet so that they may be trimmed to fit the glass pane. Releasable means is also provided for mounting the panel sections in blocking relationship to the glass pane. In another embodiment one of the rigid foam panel sections is provided with a tapered edge so that the section will fit behind the lock on a double hung window. In a further embodiment of the invention a plurality of u-shaped channels are placed around the periphery of the rigid foam sections to form framework. Releasable means may then be secured to the framework to hold the panel structure in blocking relationship to the glass pane. A still further embodiment encompasses use of a frame of rigid foam insulation which framework is placed around the glass pane and the releasable mounting means is secured thereto.
