Does anyone have any suggestions on insulating a whole house fan for the winter? I’m pretty sure that those thin aluminum shutters aren’t slowing the heat down much. I’ve checked on the Tamarack Whole House Cooler with the R-22 lid, but they are too small for my application. I currently have a 30 inch fan installed. Thanks
