Autoclaved Aerated Concrete (often shortened to ‘AAC’) is effectively concrete with lots of closed air pockets in it. It is lightweight and energy efficient, and is produced by adding a foaming agent to concrete in a mould, then wire cutting blocks or panels from the resulting ‘cake’, and ‘cooking’ (curing) it with steam (autoclaving). AAC is well known as an environmentally friendly construction material.
Lessons learned: Replastering "Last summer we were introduced to a [...] an aerated, autoclaved cement plaster with much higher vapor permeability than most cement plaster. Unfortunately, we know now after one year on our house that it is not permeable enough. Moisture gets trapped behind it, builds up in the clay/straw/cowdung plaster under it and causes this layer to lose its bond with the cob. [...] we have replaced a section of Litewall with our clay/straw/cowdung plaster."
