This has been a ongoing subject with many of my contractors trying to prepare them for Energy Star V3 and the 2009 IECC Code requirments 
 
its interesting how many contractors dont even think about air infiltration problems as far as the top plate issue a caulking and or gasket may be used but Energy Star says no to adhesive – Liquid nail not sure why plenty on construction site I believe they feel once it sets its to rigid to flex I have one customer that followed the process and what a good blower door result compared to the norm.- Mark Crawford IECC plans examiner/inspector/ HERS rater Texas

Allison, this is also true of concrete block homes, maybe more-so. The furring strips are fastened over the rigid insulation (or directly to the block walls if foil insulation is used). The top furring strip is not always tight to the top, and is usually not butted tight to the adjacent furring. We have professionals saying that the drywall mud in the ceiling/wall joint is enough to cover this gap. Florida Energy Code requires a “sealant” (not defined) at this joint, just as you stated, but I haven’t seen a house done yet with any caulk. This would probably require an extra inspection. Any comments from the Florida builders?
