List<BR><B>Subject:</B> [GSBN] Lime plaster and expansion
joints<BR></FONT><BR></DIV>
<DIV></DIV>Dear Community,
<DIV><BR></DIV>
<DIV>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. </DIV>
<DIV><BR></DIV>
<DIV>I am always grateful that we have this community and these
discussions. </DIV>
<DIV><BR></DIV>
<DIV>Regards,</DIV>
<DIV>Laura </DIV>
