Additionally, do not use electric exhaust followers for attic room air flow as these can draw a lot more air than can be supplied through the soffit vents. This will really draw home air into the attic room, causing higher warm loss and wetness build-up. They are also vulnerable to failing, noise manufacturing and boosted energy use.
