Before we begin, here are a few key terms…
Cross Laminated Timber (CLT): several layers of lumber boards stacked crosswise and glued (or through other means of attachment) together to form sturdy, thick, structural panels.
Sequester: to take ‘hold’ of. For example, trees have the ability to ‘sequester’ carbon as they grow, and release oxygen. Even if a tree is cut down, it still continues to ‘sequester’ that carbon. Once it is burned or it starts to decompose, it no longer ‘sequesters’ the carbon, and instead releases it into the atmosphere.
Again, here is ‘sustainable’ being thrown around like a hot potato. When I first started researching for this blog, I self-defined the ‘sustainability of CLT’ as such: “If CLT continues to gain popularity as a construction material, will forests’ health then be put into jeopardy?” If I found the answer to this question to be, “no, forest health will not be affected if CLT continues to rise in fame” then CLT was, to me, considered to be ‘sustainable’.
