Abstract
The findings of recent studies from both eastern and western Canada have shown that the drying behaviour of subalpine fir (A. lasiocarpa) and balsam fir (A. balsamea) is similar, which allows common solutions to be applied based on research conducted on one species of fir or the other. This article summarizes previous research findings and good practices that can be adopted in the short term to improve the drying of fir.

Abstract
Just as human beings and plants need moisture to stay healthy, the same principle applies to organic materials such as paper, wood and textiles. With an ever-growing demand for increased productivity and the expectation of uniform product quality within the secondary wood manufacturing sector, natural materials such as wood require a climate in which processes and storage occur at a certain air humidity. As indoor climate and humidity constantly change with heating, ventilation and exhaust systems, humidification systems can help ensure uniform quality throughout production.

Abstract
L’humidité relative de l’environnement influe non seulement sur la santé des êtres humains et des plantes, mais aussi sur la performance de matériaux organiques comme le papier, le bois et les textiles. Face à la pression constante en vue d’accroître la productivité et aux attentes sur le plan de la qualité uniforme des produits, l’industrie de la transformation secondaire des produits du bois doit prendre les mesures nécessaires pour assurer un certain taux d'humidité dans ses installations de transformation et d’entreposage du bois. Étant donné que les systèmes de chauffage, de ventilation et d’échappement entraînent une variation constante du climat intérieur, les systèmes d’humidification peuvent favoriser l’uniformité de la qualité à toutes les étapes des procédés de fabrication.

Abstract
Des travaux récents tant dans l’est que dans l’ouest du Canada ont montré que le comportement au séchage du sapin subalpin (A. lasiocarpa) et du sapin baumier (A. balsamea) est similaire, ce qui permet une application de solutions communes à partir de travaux effectués sur l’une ou l’autre variété de sapin. Le présent document se veut une revue sommaire de résultats de travaux antérieurs et de bonnes pratiques pouvant être adoptées à court terme pour améliorer le séchage de cette essence.
