sequestration of carbon in harvested wood products for the united states kenneth e. skog abstract the intergovernmental panel on climate change ipcc provides guidelines for countries to report greenhouse gas removals by sinks and emissions from sources. these guidelines allow use of several accounting approaches when reporting the contri
building envelope moisture control for mixed-humid climates. use non-absorptive claddings. walls with non-absorptive cladding vinyl siding and insulated vinyl siding had among the lowest sheathing moisture content recorded in the study; this was the case for walls that faced either north or south.
if youre looking for a natural, traditional roofing material, wood shingles and shakes are difficult to beat. they offer good versatility as long as they are made from high-quality material like redwood or cedar. the only climate concerns related to these products involve constant sun or very wet, damp climates.
melting snow sitting on wood will keep it damp for weeks on end. the freeze/thaw cycle can also damage joints and loosen screws. do not simply drape the wood with plastic since dew can form underneath and cannot evaporate quickly enough for the wood to dry. canvas would get wet and keep the furniture soggy.
other effects of using wood for bioenergy may be considerable including induced land-use change, changes in supplies of wood and other materials for construction, albedo and non-radiative effects of land-cover change on climate, and long-term impacts on soil productivity.
pianos destined for japan and asia in general are taken from the 'wet' line, since japan is an island and tends to be more on the tropical or humid climate side. pianos destined for say, europe, are taken from the 'dry' line.
most natural wood decking, for instance, is chosen because many wood species used for decking have natural resistance to wind, rain, and uv rays. many of these kinds of wood decks are extremely robust no matter what your climate throws at them. but, choosing your deck according to climate can save you the time on maintenance.
the study objective was to quantify the field performance of wood-frame walls clad with a variety of common claddings in a mixed-humid climate, as well as identify the relative capabilities of the different wall assemblies to dissipate moisture when they did become wet.
search for wood that isnt on the ground: in the rain, the ground will get wet, and wood will absorb the moisture. even when it dries out somewhat, wood on the ground can still be damp. dont be fooled by the dry outer appearance. a dry twig will snap cleanly when broken. keep looking until you find twigs that break crisply.

later, these natural stands were replaced by plantations of loblolly and slash pine, which were the favorites of the forest products industry because they grow well in the warm, wet climate of the southeast see the photo . loblolly pine plantations achieve a maximum biomass of 125 metric tons per hectare in about 40 years . but because this species achieves its maximum rate of biomass accrual in about 20 years, rotations are usually kept short to maintain the fastest carbon uptake possible.
wood . traditional wood siding, either planks or shingles, looks beautiful, but takes more maintenance than other products and suffers more in the weather. its especially susceptible to rot, mildew, and insect damage in humid areas. temperature fluctuations make it expand and contract which causes cracking and splitting.
average weather in fort leonard wood missouri, united states in fort leonard wood, the summers are hot, muggy, and wet; the winters are very cold; and it is partly cloudy year round. over the course of the year, the temperature typically varies from 26 f to 89 f and is rarely below 9 f or above 98 f .
for wood with moisture in it, here is what the wood handbook says: 'wood that contains moisture reacts differently to varying temperature than does dry wood. when moist wood is heated, it tends to expand because of normal thermal expansion and to shrink because of loss in moisture content.
the woods and composite materials mentioned above are all suitable for wet and dry environments. oak hardwoods such as white oak, red oak and post oak can be used for decking and railing material in dry climates. the low humidity allows the wood to withstand softening due to rot.
wood will shrink and cracks will develop during dry seasons due to a loss of moisture and expand during hot and humid, summer-type conditions. a heavier, denser wood will do better with water than a light wood. water also will cause breakdowns, such as rotting and molding on the wood.
acclimating your wood in summer only really makes sense if you know that your wood is extra wet, either because your moisture meter told you so or because the lumber was stored in an environment that wasnt climate controlled. if your lumber is in a condition that acclimating it during the summer makes sense, you may want to reevaluate your situation.

wet, humid climate - decking timber. an important point regarding cedar, we already explained why we use screws and not nails, well, especially in the case of cedar, you have to use galvanised steel screws because cedar reacts badly to iron by developing a bluish stain within the wood, where cedar and iron meet.
a more serious condition exists when an unfinished wood product has acclimated to a humidity level above 70%. if wood which has stabilized at this relative humidity is subjected to a very dry climate, with relative humidity levels around 10-15%, the high moisture content in the wood will boil-off very quickly.
wet/dry; when a tree is cut down the wood is green. over time the wood seasons, natural moisture in it evaporates. depending on the type of wood, it takes 6 to 12 months to become seasoned.
engineered wood is real wood on the top, and is built board by board as opposed to cutting boards from a natural hunk of a tree. this is considered the best flooring for a humid climate because it is less vulnerable than solid wood and it can be used in any region. if solid wood is the only floor for you, there are a few sizes that can be considered.
