There we go, rock wool.
Indeed, I was surprised that none of the vents were ducted. Of course, I will use proper ducting and caps on the outside, made for venting.
The whole house fans I was talking about are the ones that mount to the ceiling joists, and you can see the screen or louvers on your ceiling. The attic fans I'm talking about are the ones that mount to a vertical wall in your attic or the ones that mount to the roof, if no vertical walls are present or you have no space on them.
What do you mean by this sentence: "adequate make-up air (intake) is available."?
Thanks.
