ABSTRACT:
A storm window having a peripheral frame including an integral, angulated leg portion for extension, abutment and securement to the jamb of an interior window. The storm window of the present invention includes a window frame extrusion having a plurality of integrally formed slide tracts for receiving a window unit therein, and an inwardly facing flange portion extending therearound at a selected angle relative thereto. The angulated flange includes an outer planar flange portion in generally parallel spaced relationship with said slide track portions for direct securement to a window jamb of an existing window. This particular construction facilitates the flush securement and sealing of the storm window of the present invention to the existing window in a manner facilitating installation and reducing thermal conductivity between the adjacent window structures as well as air infiltration therebetween. The angulated flange further provides structural integrity beyond that of contemporary storm window constructions. In this manner, the storm window of the present invention may be affixed to a conventional interior window in a manner permitting access to the storm window without interference between it and the original window and in a manner substantially reducing air infiltration, conduction and radiation heat loss.
