High-R Walls, Part 1: Wall Assembly

Many years ago Joe Lstiburek, building science rock star, introduced his “perfect wall” concept, although this perfection extends only to energy and moisture performance. There are other elements that I consider worthy of discussion: climate impact, cost and buildability.   http://zeroenergyproject.org/2016/01/25/high-r-walls-part-1-wall-assembly/

High-R Walls, Part 2: Moisture Content

Zero-energy homes usually require a wall system with an insulating value of R-30 to R-40, at least in cold, heating-dominated climates. In Part 1 of this series, I suggested that you can’t go wrong with rigid insulation sheathing or with double-stud walls filled with fibrous insulation. http://zeroenergyproject.org/2016/01/27/high-r-walls-part-2-moisture-content/
