The moment a tree is cut down and its biological processes are interrupted, it can be said that the deterioration process of wood also begins. Steps such as the correct cutting of the trunk, drying and storage or the precise specification of the best species for each use will determine its durability. Composed basically of cellulose, hemicellulose and lignin, each wood species has a certain natural durability, also influenced by the environmental conditions of where it is inserted, such as temperature, humidity, oxygen content, and the microorganisms and insects present there. Generally, surface treatments are used to increase the protection of different parts, such as varnishes, oils and other chemical processes. But there are situations in which untreated wood can be used outdoors, achieving a gray and sober aesthetic that blends into the exterior and brings personality to the building.
In recent years, we have published many articles about wood. Addressing trends of use, possibilities for log wood, panels, curves, and finishes, innovations in tall building structures, and wood's behavior towards fire, these articles have explicated a wide variety of the material's applications and characteristics. A specific type of wood, Cross Laminated Timber (CLT), has emerged as highly structurally efficient with thermal, seismic, and even sensory benefits, described by specialists as the concrete of the future. But when we post these articles on social media, we frequently encounter comments from our readers concerned about the impact of deforestation. Although we may see wood as a great building material of the future, we must ask ourselves: is it possible to continue cutting down trees and using their wood while still calling it sustainable?
