Wood Basics: Exploring the Different Types Uses and Best Care for Wooden Materials

VIDEO ON THE TOPIC: What to do with sawdust?

Last updated: December 11, T here's plenty of it, it's relatively cheap or even free , it's environmentally friendly, it looks great, it's warm and cozy, it's super-strong, it lasts hundreds or even thousands of years, and you can use it for everything from building bridges to making paper or heating your home.

It's wood —and it's quite possibly the most useful and versatile material on the planet, with many thousands of different uses. So what is it that makes wood so good? Let's take a closer look! Photo: Wood really does grow on—or rather in—trees.

Who'd have thought you could make a lovely coffee table or a fruit bowl from a gnarled old specimen like this? The outer part of a tree trunk might look dead, but it's very much alive: tree trunks grow outward getting wider as well as upward getting higher.

You often hear people grumbling about money and all kinds of other things that "don't grow on trees"; the great thing about wood is that it does grow on trees—or, more specifically, in their trunks and branches.

Photo: This fence pole was once a tree—and you can still clearly see the annual growth rings if you look down on it from above. Take a tree and peel off the outer "skin" or bark and what you'll find is two kinds of wood. Closest to the edge there's a moist, light, living layer called sapwood packed with tubes called xylem that help a tree pipe water and nutrients up from its roots to its leaves; inside the sapwood there's a much darker, harder, part of the tree called the heartwood , which is dead, where the xylem tubes have blocked up with resins or gums and stopped working.

Around the outer edge of the sapwood and the trunk is a thin active layer called the cambium where the tree is actually growing outward by a little bit each year, forming those famous annual rings that tell us how old a tree is.

Slice horizontally through a tree, running the saw parallel to the ground perpendicular to the trunk , and you'll see the annual rings one new one added each year making up the cross-section.

Cut vertically through a tree trunk and you'll see lines inside running parallel to the trunk formed by the xylem tubes, forming the inner structure of the wood known as its grain. You'll also see occasional wonky ovals interrupting the grain called knots , which are the places where the branches grew out from the trunk of a tree.

Knots can make wood look attractive, but they can also weaken its structure. Wood is divided into two distinct kinds called hardwood and softwood, though confusingly the names don't always refer to its actual hardness or softness:.

Its leaves inset drop off in the fall and new ones grow in spring. It's generally true that hardwoods are harder than softwoods, but not always. Balsa is the best-known example of a hardwood that is actually very soft. Hardwoods have lovely, attractive grains and are used for such things as making fine furniture and decorative woodwork, whereas softwoods often come from very tall, straight trees, and are better suited for construction work in the form of planks, poles, and so on.

Look at some freshly cut wood under a microscope and you'll see it's made up of cells, like any other plant. The cells are made of three substances called cellulose about 50 percent , lignin which makes up a fifth to a quarter of hardwoods but a quarter to a third of softwoods , and hemicellulose the remainder.

Broadly speaking, cellulose is the fibrous bulk of a tree, while lignin is the adhesive that holds the fibers together. The inner structure of a tree makes wood what it is—what it looks like, how it behaves, and what we can use it for.

There are actually hundreds of different species of trees, so making generalizations about something called "wood" isn't always that helpful: balsa wood is different from oak, which isn't quite the same as hazel, which is different again from walnut. Having said that, different types of wood have more in common with one another than with, say, metals , ceramics , and plastics.

Physically, wood is strong and stiff but, compared to a material like steel , it's also light and flexible. It has another interesting property too. Metals, plastics, and ceramics tend to have a fairly uniform inner structure and that makes them isotropic : they behave exactly the same way in all directions.

Wood is different due to its annual-ring-and-grain structure. You can usually bend and snap a small, dead, tree branch with your bare hands, but you'll find it almost impossible to stretch or compress the same branch if you try pulling or pushing it in the opposite direction.

The same holds when you're cutting wood. If you've ever chopped wood with an ax, you'll know it splits really easily if you slice with the blade along the grain, but it's much harder to chop the opposite way through the grain. We say wood is anisotropic , which means a lump of wood has different properties in different directions.

Photo: Wood is a traditional building material, as popular today as ever. Because wood is anisotropic, natural wooden beams work better as vertical posts where they are in compression than horizontal beams where they are in tension. That's not a problem here, because these beams are laminated so they are equally strong in all directions. The diagonal members add further strength to stop the horizontal beams from bending. Read more about how buildings work.

That's not just important to someone chopping away in the woodshed: it also matters when you're using wood in construction. Traditional wooden buildings are supported by huge vertical poles that transmit forces down into the ground along their length, parallel to the grain. That's a good way to use wood because it generally has high compressive strength resistance to squeezing when you load it in the same direction as the grain. Wooden poles are much weaker placed horizontally; they need plenty of support to stop them bending and snapping.

That's because they have lower tensile strength resistance to bending or pulling forces across the grain. Not all woods are the same, however. Oak has much higher tensile strength than many other woods, which is why it was traditionally used to make the heavy, horizontal beams in old buildings.

Other factors such as how well seasoned dry a piece of wood is as discussed below and how dense it is also affect its strength. Chart: Wood can be very weak. In tension for example, stretched horizontally in struts or beams , it's one of the weakest of all common materials. That's why it's more likely to be used in compression in vertical beams , where it's very much stronger. Concrete suffers from the same problem, which it's why it's often reinforced with steel. All woods are different, and vary with atmospheric conditions, but typically they're 10—30 times stronger in the longitudinal direction than in the radial direction see the inset picture of a tree trunk for an explanation of these terms.

One of the best things about wood is how long it lasts. Browsing through the daily news, you'll often read that archeologists have unearthed the buried remains of some ancient wooden article—a wooden tool , perhaps, or a simple rowboat or the remnants of a huge building—that are hundreds or even thousands of years old.

Providing a wooden object is properly preserved something else we discuss later , it will easily outlast the person who made it. But just like that person, a wooden object was once a living thing—and it's a natural material. Like other natural materials, it's subject to the natural forces of decay through a process known as rotting , in which organisms such as fungi and insects such as termites and beetles gradually nibble away the cellulose and lignin and reduce wood to dust and memories.

Photo: Under attack! The big problem with wood is that it's a natural material subject to attack from other natural things, notably fungi and insects. This is what Formosan subterranean termites can do to wood. Wood has many other interesting characteristics. It's hygroscopic , which means that, just like a sponge, it absorbs water and swells up in damp conditions, giving out the water again when the air dries and the temperature rises.

If, like mine, your home has wooden windows, you'll probably notice that they open much more easily in summer than in winter, when the damp outdoor conditions make them swell into the frames not necessarily such a bad thing, since it helps to keep out the cold. Why does wood absorb water? Remember that the trunk of a tree is designed to carry water from the roots to the leaves: it's pretty much a water superhighway. A freshly cut piece of "green" wood typically contains a huge amount of hidden water, making it very difficult to burn as firewood without a great deal of smoking and spitting.

Some kinds of wood can soak up several times their own weight of water, which is absorbed inside the wood by the very same structures that transported water from the roots of the tree to the leaves when the tree was a living, growing plant. What other properties does wood have? Although wood can absorb sound very effectively another useful property in buildings, where people value sound insulation shutting out their neighbors , wooden objects can also be designed to transmit and amplify sounds—that's how musical instruments work.

Wood is generally a poor conductor of electricity but, interestingly, it's piezoelectric an electric charge will build up on wood if you squeeze it the right way. Wood was one of the first natural materials people learned to use, and it's never lost its popularity. These days, it's particularly prized for being a natural and environmentally friendly product.

Forestry is a rare example of something that has the potential to be completely sustainable : in theory, if you plant a new tree for every old tree you cut down, you can go on using wood forever without damaging the planet. In practice, you need to replace like with like and forestry is not automatically sustainable, whatever papermakers like us to believe.

A brand new tree has much less ecological value than a mature tree that's hundreds of years old so planting a thousand saplings may be no replacement for felling just a handful of ancient trees. Logging can be hugely environmentally damaging, whether it involves clearcutting a tropical rainforest or selectively felling mature trees in old-growth temperate woodland. Some of the processes and chemicals used in forestry and woodworking are also environmentally damaging ; chlorine, used to bleach wood fibers to make paper, can cause water pollution in rivers , for example.

But on the positive side, growing trees remove carbon dioxide from the atmosphere and planting more of them is one way to reduce the effects of climate change.

Trees also provide important habitats for many other species and help to increase biodiversity the wide range of living organisms on Earth. Practiced the right way, forestry is a good example of how people can live in perfect harmony with the planet. How does wood get from the tree to the roof of your house, your bookshelf, or the chair you're sitting on? It's a longer and more complex journey than you might think that takes in harvesting, seasoning, preserving and other treatment, and cutting.

Here's a brief guide. Photo: Chopping down a longleaf pine is only the start of the fun: now you've got to get it home preferably without damaging the rest of the forest in the process. That's where this skidder machine comes in, lifting up the logs with a hydraulic crane and dragging them away with a powerful diesel engine. Photo by Randy C. Murray courtesy of US Army. Growing plants for food is called agriculture; growing trees for human use is silviculture —and the two things have a great deal in common.

Wood is a plant crop that must be harvested just like any other, but the difference is how long trees take to grow, often many years or even decades. How wood is harvested depends on whether trees are growing in plantations where there are hundreds or thousands of the same species, generally of similar age or in mature forests where there's a mixture of different species and trees of widely differing ages. Planted trees may be grown according to a precise plan and clear-cut the entire forest is felled when they reach maturity.

A drastic approach like that makes sense if the trees are a fast-growing species planted specifically for use as biomass fuel, for example. Individual trees can also be selectively felled from mixed forests and either dragged away by machine or animal or even if it makes economic and environmental sense hauled upward by helicopter , which avoids damaging other nearby trees.

Sometimes trees have their bark and small branches removed in the forest before being hauled away to a lumber yard for further processing, though they can also be removed intact, with the entire processing done offsite.

It all depends on the value of the tree, the growing conditions, how far away the lumber yard is, and how easy the tree is to transport. Another interesting form of forestry is called coppicing , which involves removing long, thin, low-growing branches from trees such as hazel and willow in a careful and respectful way that does no long-term damage.

Global warming and climate change have been a hot issue in the recent past. Carbon accounting in wood products and investigation of the role of forest products in climate change mitigation is now gaining momentum all over the world.

The impacts of forest industries and wood utilization on the environment were considered. The effects of tree harvesting and logging operations on forest biodiversity, soil erosion, soil compaction and hydrological cycle are reported. Environmental pollution due to wood processing, wood utilization and waste management in forest industries was discussed. Methods of mitigating the detrimental effect of the operations of forest industries in Nigeria on the environment are suggested. Forests have been the major source of livelihood for most Nigerian. The forestry sector is one of the main pivots on which the nation's welfare was built. The forest is not only important for material goods but also as a valuable ecological and cultural resource. The forestry subsector has over the years contributed immensely to the socio-economic development in the country. It ranks among one of the highest revenue and employment generating sectors. It also serves as resource base for many forest industries.

Wood is one of the most versatile raw materials in the world: Furniture , musical instruments, floors, paper or entire houses — all of these things can be made out of wood. Of course, there are also wooden accessories and furniture, which fulfill the highest demands on quality and design. People already valued the quality of wood thousands of years ago: This natural product was the only raw material offering good quality at manageable costs for a long time — until the 19th century. By this point, metal and plastic temporarily pushed wood out of living rooms.

Engineered wood , also called mass timber , composite wood , man-made wood , or manufactured board , includes a range of derivative wood products which are manufactured by binding or fixing the strands, particles, fibres, or veneers or boards of wood, together with adhesives , or other methods of fixation [1] to form composite material. The panels vary in size but can range upwards of 64 by 8 feet 20m x 2. Engineered wood products are used in a variety of applications, from home construction to commercial buildings to industrial products.

However, trade restrictions are a growing challenge for the sector. For the first time in a decade, all three subregions showed growth in both production and consumption of sawn softwood. The improving economy, in particular related to construction and renovation, has played a strong role in this growth, but there is also increased momentum behind replacing carbon-intensive building materials with wood as a greener choice for building material, and using wood as a low-carbon source of energy. One of the major barriers to growth is the increasing level of restrictions on trade. As a recent example, a number of traditional log suppliers have imposed export restrictions designed to develop their domestic industry. The most visible trade issue in the area of wood products is the US-Canada softwood lumber agreement, which expired in and is the object of intense negotiations. One of the main elements of the allegations by the US Department of Commerce, and a basis for applied subsidy rates, is the issuance of log export restrictions on government-owned forestlands across Canada and, notably, on private lands in British Columbia which is the leading sawn softwood-exporting province in Canada. Wood products are subject to substantially more non-tariff measures than other manufactured products, which can have significant effects on their international trade. Examples include non-tariff measures intended to prevent insect infections, to assure the legal sourcing of timber, and to protect domestic producers. Such measures tend to increase costs for exporting countries in favour of domestic producers.

Wood may be the most environmentally friendly material available for building Industrial Materials (CORRIM) compared the environmental impacts of homes.
