![]() This is important to remember when building a wood fence, for example, so that future shrinkage can be taken into consideration. This is due to the fact that water is used to impregnate the chemicals into the wood at the factory. It’s also great to test firewood for proper seasoning.įinally, be sure to take note that fresh, treated wood will probably have a higher moisture content (35%-75%). Oakwood is heavy, long-lasting, and considerably more durable and expensive than maple. Maple is a pale hardwood with an extremely tight and even grain, there are are soft and hard varieties of maple. This is the moisture meter I use almost on a daily basis. Although maple and oak are both hardwoods, the trees differ vastly from each other. They are great little tools and aren’t too expensive. If you want to test for moisture content before you buy, pick up a moisture meter. Other more stringent kiln-dried standards exist but KD-19 is the most common. KD-19 (Kiln Dried 19%) lumber will have an average moisture content somewhere around 15%. This means that it has to have a moisture content below 19%. Most building lumber sold at home stores is kiln dried to some extent. Average equilibrium for interior wood in US ~8%.Enter the moisture content in the calculator and hit “enter”. Below are some typical moisture contents of lumber. Wetter wood will be heavier than drier wood. If you choose pressure treated lumber, take note that 85% of pressure treated lumber sold in the US is southern yellow pine, so that is probably what you have. You can usually find the species of wood by looking on the tag stapled to one of the ends. Spruce-pine-fir (SPF), which can either be subalpine fir, balsam fir, black spruce, Engelmann spruce, jack pine, lodgepole pine, red spruce, or white spruce.Southern Yellow Pine (SYP), which can either be loblolly, longleaf, shortleaf, or slash pine.Nevertheless, it is a popular choice for hardwood flooring because of the smooth finish that the fine grain. Hem-fir, which can either be western hemlock, California red fir, grand fir, noble fir, Pacific silver fir, or white fir Cherry is a softer wood than either oak or maple.Douglas-fir-larch, which can either be Douglas-fir or western larch.for framing a wall) is usually one of the following softwoods (also called whitewoods): The most common species of dimensional building lumber (e.g. A few examples of these are shown in the picture above. Wood used for furniture and for appearance is often of a hardwood (or Pine) variety. Common Lumber Types Common wood species for furniture making. Standard treated wood has about 0.06 lbs/cubic foot chemical retention while wood treated for ground contact has about 0.15 lbs/cubic foot. Treated wood has chemicals (usually MCA or micronized copper azole) in it that will slightly increase the weight. Forest Serviceįirst, select whether or not you have treated wood. *Most of the specific gravities used in this calculator are derived from “Wood Handbook, Wood as an Engineering Material” written by the U.S.
