While I haven't used the LSL in a plate application, it has been my
experience that most all of the engineered wood products are very
dimensionally stable most of the time. When I worked for Trus Joist
MacMillan, the company that developed LSL I remember taking a piece of the
material and fully immersing it in an aquarium full of tap water for a
period of about 7 weeks, until the point that fungus was growing on it. It
didn't change dimension significantly, the thickness increased by maybe 5%
if I remember correctly (~1.32" thick after soaking for 7 weeks from an
original thickness of 1.25"). Hope this helps.

Subject: Wood Frame Shrinkage - LSL
Does anyone have experience in using engineered wood products such as LSL in
a plate application. We are considering this for the top and bottom wall
plates in a 5 story wood building in which we wish to limit total
shrinkage/settlement due to an adjacent steel framed component. The rim
boards and blocking are also LSL. The material is advertised as being very
dimensionally stable, but I have not seen it used it for wall plates before.
