Hi,

Guess this is my day for posting questions.
Great group; sure appreciate all the help and opinions.

Have a typical colonial in New England.
Have never thought about this in the past, but was wondering:

Have an attic fan mounted in a screened opening on one end of the
attic. A belt driven model, that does a great job.
Also has louvres mounted on the opening; when the fan is on, the
louvres open automatically
due to the air flow.

The opening on the other end of the attic just has a screen; no
louvres.
My kids have moved into a house that also has screened openings on
both ends of their
attic. Was thinking of putting in a similar attic fan for them.
Thus my question:

Why does one need, or want, these type of automatic openingh louvres ?
Their isn't any on my other end of the attic, and no rain ever seems
to get in.

Wouldn't the fan installation be just as effective without these
auto-opening louvres ?

Funny that I've never thought about them, but now I really don't see
what good they actually do.

Most houses I see don't seem to have them; whether there is a fan
installed or not.

Thoughts on ?

Thanks,
Bob

It may be a matter of the prevailing winds.
