AAC is a great product but it does present some challenges to work with
I've seen a few people build with AAC. It's strong, energy efficient, and sustainable. However it is a bit expensive to build with and it does take a while to get the knack of working with it. The blocks are also quite heavy, so you really know about it after a day's work. Respect to people who build with it, but I'd prefer to work with SIPs myself.
**Thanks Michael, for the link and reference in your comment. It's clearly a useful read, but has to be taken with a grain of salt since it's obviously an infomercial for AAC. I'm all for AAC for the higher end of construction and where labor cost is not likely to be a big problem, or where the strength is that important.
***Thanks again Michael, for the follow up comment. I still agree AAC is great. I'm not sure how you got to 10% cheaper than SIPs but you have to consider there are many types and manufactures of SIPs to compare while only two ACC makers that I know of. So it really depends which one you're looking at and where it's from. And you need to consider the labor component in the build to make any real comparison. Plus the materials vary. Some are made of wood, some magnesium Dragonboard material, some metal. So fire ratings will vary widely too. Same with the Styrofoam issue. Many SIPs use polyurethane foam which I consider much safer. The SIPs I was working with till recently are steel skins with polyurethane foam. And pretty reasonable in price really. They could put up a 2500 sf house shell in 4 days which is a good savings in labor - plus the panels were so easy to work with you could use low-skilled staff. Sadly, they've recently closed their doors as a result of the sharp drop in building. I'm hoping they can make a come back.

A 21st Century Building Product
Autoclaved Aerated Concrete (AAC) is a building material that is now available on the West Coast,
In a world of paradigm shifts, in a post 9/11 and post Katrina environment, where the most conservative of trades, the built community, has begun to embrace newer technologies, the end-users of buildings, you and me, who spend 80% of our time in them, will reap significant gains in productivity, less absenteeism -- in sum, a friendlier human environment.
It is the material of expanding value, in the form of occupant safety, health and energy efficiency.

The Right Stuff
AAC is the only truly green masonry material known to man with superior thermal insulation qualities.
It should be the first material choice for owners, occupants and build professionals seeking significant energy efficiency from their buildings.

I check locally here in Seattle, AAC is 10% cheaper than SIP panel. Also AAC comes in Panel format, so the same crane and labors can install the AAC building. I'm more concerned about fir rating by SIP (8 minutes only... more »
