ABSTRACT:
A storm window type closure which is adapted to be installed adjacent the interior side of an existing primary window unit. The present invention incorporates a main frame and associated runner assembly of such a low profile that the designed movement of the primary window unit may be accomplished without undue obstruction thereby allowing convenient access to the same. Additionally the present invention provides a substantial dead air space between the primary window and the storm window thereby increasing both the acoustic and thermal insulation qualities of the same.
The present invention relates to windows and more particularly to storm windows which are adapted to be installed adjacent a preexisting primary window unit.
