Mass timber products are rapidly growing in fascination and popularity across the North American construction market, in which wood products are tested for durability and resiliency according to standards set by the American Wood Protection Association. Presently, the American Wood Protection Association (AWPA) E1 Standard calls for a test sample size of 2.54cm x 2.54cm x 0.64cm, which may be too small to encompass the large spacing between the bond lines of CLT, a multilayered mass timber product composed of layers of kiln-dried lumber alternating in grain direction. The objective of this study was to evaluate the resistance of untreated CLT against subterranean termites (Reticulitermes spp.) found in the southeastern United States using two-sample choice testing and extend the AWPA E1-17 Standard to accommodate the larger building material. Choice-testing methods were evaluated over a 4-week period for mass loss, visual rating, mold formation, and termite mortality.
