Looking for help designing a durable & efficient wall for a house in the mountains near Asheville NC at 4,000 ft. elevation
I am trying to use articles from this site and from Building Science to design a durable and efficient wall for a residence in the mountains near Asheville NC at 4,000 feet of elevation.
Which would be a better wall; a 12" AAC wall with interior plaster and exterior stucco, or an 8" AAC wall with 3" of closed cell spray foam or XPS sheets on the exterior and then a 1" air/drainage space and then hardiplank? Would the increased complexity and cost of the second option be worth it? Are there any good spacers for the air/drainage plane that are not thermal bridges and will not corrode?
