This Material Survives Hurricanes, So Why don't We Use It?

A block that floats in water. Survives a 2,000° fire for 4 hours. Used in 75% of new UK homes and 60% of German homes. And it has no approved pathway in the American building code. Not because it failed a test — because it passed every one. Autoclaved aerated concrete — AAC — is a 20 billion dollar global industry across 3,000 factories worldwide. In America, there are two factories. The International Residential Code doesn't list it as an approved material. The American Wood Council has 40 staff members working specifically on building codes. AAC has none. Not banned. Just buried. There's a difference — and it matters if you want to build with it right now.
