[Greenbuilding] [BULK] Re: Advanced Framing

[Lawrence Lile]

I caulked 'em.  Most projects can't stand a a guy hanging around every
weekend for a month caulking, but I didn't cost me anything.  Blocking
is a really good idea, although it reduces insulation thickness at that
point.  Maybe not a crisis in a 2X6 wall, but in 2X4 it would be a lot.

thinking about all the different places to caulk to
reduce air intrusion got me to wonder, what do you do
about the horizontal seams of the sheething?  
If you are gasketing sole plates and caulking around
exterior boxes, what protects the plywood seams (~1/8
inch with clips)?  Tape?

I am really loving this discussion.
