Question

I am insulating the ceiling above my garage and have installed ventilation baffles between the rafters. I am going to use blown cellulose insulation. The question I have is how do I keep the insulation from being blown down into the soffit vents? Do I just seal that gap with some unfaced fiberglass insulation? I used plastic baffles from the home improvement store. Will this fiberglass insulation cause any of this air to be "pinched" off?

Thanks

If, by "ventilation baffles" you are referring to pieces of plywood attached to the bottom of the rafters where the soffit vents are located, you won't have a problem. the insulation shouldn't be blown over the tops of these baffles, so the air flow will not be lost. DON'T close off the soffit vents with fiberglass insulation -- that will block the air flow.

Actually, I meant the plastic, preformed baffels that you attach to the roof sheathing right at the top plate of the wall. After I stapled those on there is a gap between the baffle and the top plate of the wall. (about 4-6"). If I blow insulation there right now I will end up with insulation in the soffit (no good!).
