Insulate around attic fan

[Charles Martin in Seattle]

I found that there are daylight gaps around my attic fan, a bit to large for caulk. What's the best way to insulate them?

Thanks.

Stuff them with fiberglass or spray in some of the urethane foam that expands.

Is it hard to 'trim' it out with molding to cover the gaps?

if not, home stores sell Caulking Rod, basicly foam in the shape of rope that you can push into the big gaps and caulk over it.

Too large for caulk? Anything narrower than the Grand Canyon can be caulked!
