EcoRenovator - View Single Post - Insulating a whole house fan louvered vent

I have a whole house attic fan in the upstairs hallway that has a louvered opening into the living area. Especially during the summer season, Since the fan is not often used during the hottest part of the year when the A/C is on, I can feel the heat blasting down thru this louvered opening. Has anyone constructed an insulated cover that can be easily opened to allow occasional operation of the fan? I have been considering just building a 2" thick foam wall around the fan with a 3/4" thick polystyrene foam lid. The lid would be cut into four sections and each hinged (with tape) so that they woud be blown into an open position when the fan was turned on and would fall back closed when the fan was off. Has anyone else had this situation and how did you solve it?
