Air Tight

I know the answer to my question has probably been asked before but I cannot seem to find it on hear. Anyways a 2x6 wall. Plywood on both sides, sealed cavity. I plan to seal the inner wall with gaskets from Conservation Tec. Do I need to seal the outside sheeting, by that I mean do I need gaskets under the sheeting hear as well or just the inside.

Paul,
First of all, you may want to read an article that addresses your question: One Air Barrier or Two?

Second, you might be interested to know that many builders have concluded that it's easier to tape plywood seams than it is to install gaskets between plywood sheathing and the studs. For more information on taping plywood seams, you might want to read these two articles:

Yes i had planned on taping seams as well. Guess gaskets might be a bit of an over kill.
Thanks
