Funny you should mention Sweden: I first encountered AAC  in  
Stockholm in 1974. Poking around on a construction site, they were  
making the partitions between apartments  ( hmm,   apart - ments;  
never noticed that before; what would a togetherment be?  ) out of  
these lightweight inert blocks you could cut with a handsaw. It  
seemed very appropriate for that application.  As architecture  
students, we thought it was hella cool stuff.
