The Perfect Wall (wonkish)

I've adopted the (wonkish) tag from one of my favorite writers. I'll leave it to you to figure out who it is since he doesn't write about home design and it would be way off track to mention here. A different favorite writer, one who does write about home design although in a very technical way  is Joe Lstiburek of Building Sciences Corporation. I highly recommend that you visit the BSC site if you're interested in technical analysis of building performance issues. Anyway....this is a great article (in Joe's inimitable style) that helps to clarify the complicated interaction of  moisture, air, and heat.
