Nice write-up. I have a cheap whole house fan right now that can displace all the air in our house in a matter of minutes. I throw fiberglass insulation strips on it in the wintertime, but I know that is nowhere near good insulation.
We are moving soon, so instead of fixing the current situation, I have been thinking about how to improve it at the next house. I came up with using a centrifugal fan to minimize the footprint of the attic hole. Plus they seem to be more efficient and quieter than propeller style fans. Has anyone tried using one of these?
