The reality of timber’s nature, and without a doubt, component of its attraction over the centuries, is that it is a hygroscopic product. Up until it is totally sealed, wood constantly engages with moisture in its setting and will soak up or release dampness as necessary to locate an equilibrium with its setting.
Analyzed closely, wood’s lengthy, hollow cell framework indicates that each board is made up of bundles of long cells, consider a pile of drinking straws. In a living tree, those paths operate to relocate dampness and nutrients from the origins to the branches and leaves of the tree. As soon as the tree is dropped, those pathways start to shed that wetness as the timber dries out. That moisture is normally not changed as if in a living tree, and the wood’s wetness degree will drop substantially as it dries. The wood drying kiln procedure helps to attract that wetness out while decreasing the damages to the timber that fast modifications might trigger.
Why is that so essential?
Green or wet timbers do not work good with anything from constructing products to camping. Its efficiency as environment-friendly lumber can be unforeseeable because of that inescapable wetness loss after the living tree is dropped. As it dries out, wood can turn, warp, fracture, as well as reduce in its physical dimensions, making it much less than suitable for floor covering, buildings, or woodworking. It’s an ongoing cycle in timber.
Even when timber has actually been kiln-dried, it might have a documented moisture content, but at any kind of action of the procedure after the kiln, like transportation, storage space manufacturing, or installation, it is feasible for timber, also manufactured timber products, to shed extra wetness in a completely dry environment or re-absorb ambient wetness, changing its moisture content and also perhaps even its dimensions. If that dampness increases or lowers, for example, after a timber floor has been mounted, crowning, buckling, voids, or various other moisture-related troubles can endanger the flooring’s stability, any type of completed timber project or product can be threatened by wetness discrepancies in the used timber.
