Matt Hoople: Oh, yeah? Well, your so-called comment is a joke! I’m reporting it to the KGB, the STP, and the LOL!  
 
BTW, are you any relation to Mott the?

Kent R.: See you there! 
 
MB Thakar: I’ll definitely check out that resource. 
 
Ken B.: Welcome back! 
 
Ernest: The yellow that you see was actually some kind of sheet material off of a bigger roll than tape comes on. Not sure what it was, but it may have had gaffer’s tape holding it together.

It may be beyond your expertise, or you may have just not been paying attention, but is the heat of the opossum (lower picture withe the baby) made from yellow gaffers tape?

Allison, Glad to hear you will venture into areas you have not written about before — such as climate change. This group — TransitionUS — would support you in addressing both peak oil and climate change. It is an innovative, community-relevant and positive way to deal with these “possibilities”.

Allison, I look forward to your workshop in Raleigh. We just committed to being a sponsor for the event and will be doing a presentation on SIPs after your workshop.

M. Johnson: Happy New Year to you, too! I do agree that sealing and insulating the ceiling rather than encapsulating the roofline with spray foam makes a lot of sense in some cases. It can definitely be more cost effective, but one important factor to consider is whether there’s an air handler and ductwork in the attic.  
 
With the central Texas house, another option would be to put up a wall in the attic between the space over the garage and the space over the conditioned space. That generally saves on foam and can be done easily with materials like housewrap to spray the foam against. Then if you want insulation over the garage, blow in cellulose or fiberglass. I’m not a huge fan of spraying foam down onto the attic floor because you can use products like Owens-Cornings Energy Complete, Knauf’s Ecoseal, or regular caulk & foam to seal the top plates and penetrations. Then blow cellulose or fiberglass and you’ve got a much less expensive treatment that can be just as effective if done properly.

Happy New Year to you too, and wishing you great success in 2013. 
 
One topic I find highly interesting is the borderline where foam insulation at the roofline is a good idea. Here on the Gulf Coast, some builders have convinced me there is hazard to that method, and equal performance can be attained at lower cost: with near-perfect sealing at the ceiling plane, and conventional ventilated attic. You may or may not agree. 
 
Let me give an inspection question: Central Texas where is less humid, foamed roofline including attached garage. Access to attic is a fold-down stair in garage. Building inspector objects, and says one solution is to add such foam at the garage ceiling plane. Do you agree? Thank you for any observations.
