Abstract
A system of rigid, generally planar dimensions adapted to by removably, hingeably coupled to a conventional ventilator louver assembly to environmentally seal same to prevent energy losses. The louver covering system includes a rigid, generally rectangular frame formed of specially extruded members, which frame surroundably supports a rigid, generally planar insulating sheet. The frame includes front, side, and rear extrusion members which include integral bosses to aid in assembly. A separate, rigid, elongated extruded hanging rail having a hinge portion is adapted to be permanently coupled to the louver assembly. The system frame rear includes a cooperating hinge portion, which, when coupled to the aforementioned hanging rail hinge coupling extrusion enables the system to be hingeably swung to a closed position relative to the louver assembly. Latching means, preferably coupled to the louver assembly, may be manually twisted to engage flange portions of the frame to seal the louver. Frame channels support a plurality of insulating strips which form a surrounding seal which minimize air currents otherwise associated with conventional louver assemblies.
