Autoclaved Aerated Concrete Aac This Old House
The panels were made by Hebel, a German manufacturer that, in 1996, opened the first AAC factory in this country. Ytong, a competitor, opened an AAC plant here in 1997. The home owner, Richard Grenamyer, has wanted an AAC house for a long time. I read about it years ago, but it wasnt available, he says.
