[GSBN] Lime plaster and expansion joints

[Laura Bartels]

Dear Community,

I've been meaning to raise this question for a bit, but now have a  
specific project that has prompted me to finally get to writing (isn't  
it often that way?). As straw bale projects are used for larger  
projects, and lime plaster is used on these, it begs the question of  
whether we need to be using expansion joints on large expanses. With  
lime having different characteristics than a cement stucco, I'd be  
curious to know from those who are well ahead of me in doing large  
straw bale projects with lime if you have seen issues with not using  
expansion joints. For those who may use them, at what square footage  
of unbroken wall has it seemed to begin to make sense? Certainly there  
are large historic lime plastered structures to look to, but given the  
fact that historically the substrate was not straw bale, I wonder also  
how we can still learn from these and apply lessons to our work.

I am always grateful that we have this community and these discussions.

Regards,
Laura
