Removable louver covering system

A removable energy saving covering system for selectively sealing conventional ventilation louver assemblies, the system comprising:

• a generally planar louver covering member adapted to be removably secured in generally horizontally oriented parallel relation with respect to a ventilation louver to be sealed, the covering member comprising a rigid, generally rectangular frame comprising:
• a rigid, elongated front extrusion member and a pair of parallel, spaced apart, elongated, rigid side extrusion members projecting perpendicularly from and coupled to said front extrusion member at opposite ends thereof;
• a rear, elongated, rigid extrusion member rigidly coupled between said side extrusion members in spaced-apart, parallel relation with respect to said front extrusion member and including an integral outwardly projecting, bottom arcuate lip member;
• a generally planar, rectangular sheet of insulating material secured by and enclosed between said frame extrusion members;
• said frame front, rear and side extrusion members being generally of C-shaped cross section and including:
• a rigid, generally planar top portion including channel means defined therein for mounting insulation strips adapted to form a seal around the periphery of said louver assembly;
• an integral, rigid side portion including inwardly extending, integral boss means for facilitating assembly of said frame;
• a lower, generally integral planar bottom generally parallel to said top and, in cooperation with said top, operative to to sandwich the edges of said sheet of insulating material therebetween;
• and,
• said front and side frame extrusion members including an integrally outwardly extending generally planar, peripheral flange;
• a rigid, generally L-shaped, elongated extruded hanging rail adapted to be permanently mounted adjacent said louver, said rail including a lower, arcuate lip portion adapted to be coupled to said rear frame member extrusion lip for hingeably mounting said covering member over said louver assembly;
• and,
• latch means for selectively securing said covering member in a closed, generally horizontal sealing position relative to said louver assembly.
