The effectiveness of using commercial polyethylene flashing and stainless-steel mesh in CLT wall systems as the termite barriers were evaluated in a short-term field test. American Wood Protection Association (AWPA) E21's visual ratings ranged from 10 to 9 in the specimens showing little damage when no physical barriers were used. Termites were able to crawl beyond the physical barriers in few specimens showing the necessity of further research on height and installation method of physical barriers. On the second part, the effect of decay caused due to Postia placenta, a brown-rot fungus, on the structural performance of hold-down brackets connected to CLT walls was evaluated using monotonic and cyclic loadings. An increase in moisture content reduced the strength of the connection system but increased the initial stiffness. Decay caused delamination of CLT laminate perpendicular to the grain, a different failure pattern, compared to the wet control and dry control specimens.
