Attic Louvres & Fan Question
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 |

Perhaps the fan and louvers came as a unit?
Perhaps the louvers protect the fan from blown rain & resulting rust? TB |
