Life Cycle Assessment

Life cycle assessment (LCA) is a rigorous study of inputs and outputs flows over the entire life of a product, or system, and their associated environmental impacts. The underlying peer- reviewed LCA, supporting this EPD, was performed by the Research Center for Renewable Materials (Université Laval, Quebec City) for LAMBTON DOORS in 2014. The present LCA is cradle-to-grave, meaning that it includes raw material acquisition, product manufacturing, packaging, construction (shipping and installation), use and end-of-life. The cradle-to-grave processes are presented by Figure 2 . Transportation is represented by “T”.
