Insulating a whole house fan

I've been told that I should insulate my whole house attic fan. Anyone got any advice on how to best do it? I started with some 1 inch rigid foam insulation, and basically made a box that fits loosely over the fan. I can take it off in the spring when I need the fan. I'm not sure if it is sealing properly at the bottom.
