A year ago, I was having some renovations done to my house, and I wanted to put a heat extraction fan in the attic, but the builder was against the idea, telling me that it would not be waterproof. And since I already had a window up there, he just advised me to leave it open.
I suspect he had never installed one before and was just making excuses.
As the hot weather approaches, I'm again thinking of getting one installed.
Anyone have any experience with these things?
How much better would a (solar-powered?) fan be compared to a passive vent?
My impression is that it's gotta be a good idea. At present, the top floor is considerably warmer than the floor below it. And as for the attic itself, it's impossible to spend any length of time up there for 6 mths of the year - which is a waste of space, as far as I'm concerned. It's big enough to stand up in, so it could become an extra room if it weren't so hot. And since it's made out of wood, it wouldn't be storing up that much heat in the structure itself, right? (Compared to bricks and concrete, that is.)
Unfortunately, I think I made the attic even hotter when I replaced the old tiled roof with a new tin one that is gray in color. I should have chosen a light green or yellow, like most other people.
