The research involved utilizing both Melamine Formaldehyde (MF) and Polyurethane (PUR) adhesives across different panel configurations, specifically 3-ply and 5-ply lamellae. The study meticulously recorded the average moisture content (MC) of both white-fir and Douglas-fir species, along with environmental conditions such as temperature (Fahrenheit) and relative humidity (RH%) during the layup process. Panel 1, using MF adhesive, consisted of 3-ply lamellae and exhibited an average white-fir MC of 9.7% and Douglas-fir MC of 15.1% under 63°F and 32% RH. Panel 2, also with MF, used 5-ply lamellae and showed a white-fir MC of 11.0% and Douglas-fir MC of 16.5% under identical environmental conditions. The majority of the tests, however, focused on PUR adhesive. For 3-ply constructions with PUR, moisture content and environmental data varied across multiple panels, with white-fir MC ranging from 8.4% to 10.2% and Douglas-fir MC from 10.0% to 14.9%, while temperature remained around 63°F and RH fluctuated between 26% and 36%. For 5-ply constructions with PUR, white-fir MC levels were generally lower, between 8.3% and 10.1%, and Douglas-fir MC ranged from 10.7% to 14.3%, with temperatures around 61-63°F and RH between 23% and 32%. The data suggests variations in adhesive performance and wood species moisture behavior under controlled environmental settings, providing crucial insights for optimizing CLT manufacturing processes with diverse wood species.","| Panel \\# | Adhesive | lamellae | Average White-fir MC% | Average Douglas-fir MC% | Temp (F) | RH% |\n| --- | --- | --- | --- | --- | --- | --- |\n| 1 | MF | 3 ply | 9.7
