I have 2x8 joists in attic with two layers of 4" fiberglass between them. I live in MI where R-38 is code--currently I have a little less than R-30--due to air space between layers. I would like to blow in approx. 6" of celluose on top of this existing fiberglass then remove my pull down stairs and replace with an insulated access panal--to better insulate this unused attic. My question is: how do I prevent blocking/clogging of the soffit vents by the celluose? This is a low slope hip roof and the soffits vents are very hard to access--and I hate the thoughts of attempting to walk across joists that I can no longer see (due to the new celluose) trying to get to the vents to unblock them!

Quote from Owens:

"To make sure the eave vents aren't blocked, Owens Corning
Raft-R-MateŽ attic vents or baffles should be installed to provide unrestricted air flow from the soffit to the attic."

You can buy similar baffles at Home Depot.
