Green lumber which can also be referred to as wet lumber is commonly used in the construction of houses. We are going to discuss what green lumber is and what effects using it can have on a home.
Trees naturally contain a lot of moisture. When they are cut down, moisture begins to evaporate from them and continues to do so until they have reached the same moisture level as the environment they are in. Green lumber, however, is a timber that still contains a higher level of moisture than its environment when it is used for construction. So, how might this affect a home?
One thing to note is that green lumber will continue its moisture evaporating process even after it has been used in construction. As the wood dries out, it will shrink and form gaps. Evidence of this may be seen with drywall when nails have been hammered into it. Gaps may form which will push a nail through the drywall. While this isn’t necessarily a major structural issue, it can still look unattractive.
Another issue is that, as water evaporates from the lumber, so do other fluids like sap. If the timber is painted before the drying out process has completed, these other fluids could cause staining in paint or even make it bubble up and look unsightly.
A more serious issue can also arise with the use of green lumber, mold. Mold can develop before it has even been used in construction which means that your newly built home may have had a mold problem before it was even finished.
Green lumber is used as a building material because it is a cheaper option. Its also important to be aware that the dryer the area, the quicker the evaporation process will be. Always involve your home inspector throughout the building process so that they can take note of any areas of concern and advise you on what to do.
