Wood flooring has been underfoot for centuries but its beauty and usefulness have never waned. What probably started out as rough boards covering a dirt surface, they have evolved into the modern age and merged with today's technology.
Not only is there an abundance of wood types to choose from but there are plenty of other considerations to think about as well.
For example, should you buy a pre-finished product or unfinished hardwood floors? Will you go for solid wood or an engineered wood floor? Each variety has it's own unique advantages and you'll need to determine which options work best for your situation.
There are also environmental factors too. If you're concerned about the environmental impact your wood floor has there are products that are certified as being from a responsibly-managed supply chain. You might also want to investigate reclaimed wood as a means of preserving existing forests.
As you can see, there's a lot to consider when choosing a wood floor but it doesn't have to be overwhelming. Take some time to discover the facets of what's involved and you'll be well prepared to make good, informed decisions and ultimately get a floor you'll be happy with.
The key point is that different cuts produce different grain patterns and correspondingly, a different look on the floor.

Heartwood is the material that's in the center portion of the tree. It's usually a darker color and is inactive tissue in a living tree.
Floors that use a combination of heartwood and sapwood will have more distinct shade differences within a particular species.
Hardwood grading is defined by NOFMA, The Wood Flooring Manufacturer's Association. (The acronym is a throwback to the original name which was 'National Oak Floor Manufacturer's Association).
NOFMA is the wood flooring trade organization that brings standardization to the wood flooring industry and oversees the wood floor certification process. Their website provides some good information on the background and benefits associated with using certified wood floor products.
NOFMA hardwood grades:
The Southern Pine Council defines standards for flooring made from southern pine, a softwood. Their system includes B&B, C, C&BTR, D, No.1, No.2 and No.3 grades, ranging from the clearest to the grade with the most visual characteristics like splits, knots and streaks.
Finally, when it comes to reclaimed and recycled wood, there are no hard and fast standards that govern wood grades. Companies that deal in this type of product establish their own grade system which best fits the description of their products. You'll see terms like "select grade", "rustic grade" and "country grade" that they use to define their products, again based on appearance.
Beveled-edge wood has a slight chamfer on its edges so that when two boards are laid side by side a very shallow V-groove is formed where they meet. This has both decorative as well as functional purposes.
The "eased" edge makes up for any slight irregularities in the subfloor that might cause some boards to stick out slightly with respect to the adjoining planks, making them a tripping hazard. Floors that are sanded and finished on-site don't have this feature nor do they need it because any irregularities are sanded flush.
Pre-finished floors are coated at the factory and receive the benefit that controlled processes and advanced coating technology can impart. Most pre-finished floors today have some form of aluminum oxide treatment for better wear protection. Some actually are impregnated with acrylic which makes the wood very durable and resistant to dings and dents.
Unfinished floors are finished on-site in your home once they're installed. Most finishes involve several coats of urethane although other coatings such as oil, oil/wax combinations and something called a 'Swedish' finish (another type of urethane coating) exist too. On-site finishing requires time for application and curing and time that you may have to be out of the house. Pre-finished floors are ready to go after installation.
Wood hardness is measured by the Janka Ball Test. It measures the amount of force that's required to push a certain size steel ball a prescribed distance into the wood's surface. The more force that's required, the harder the wood.
You can find Janka hardness tables on the web, like this Wikipedia article as well as at the websites of various wood product manufacturers.
Getting familiar with these basic 'wood-101' terms should help you gain a better understanding of what the dealers and floor sellers are talking about when you shop for wood floors.
Wood species as it pertains to flooring material falls generally into 3 categories:
Hardwoods primarily refer to North American hardwoods and include the more well known varieties like oak, maple, ash, hickory, cherry, walnut, elm and birch, among others.
Softwoods include pine, fir, cedar and other evergreen varieties. Pine is a predominant material used for wood floors. It's softer than the hardwoods that are used for flooring and will dent more easily.
While there's no specific definition of "Exotic" wood species, they typically include those from outside of North America -- places like South America, Asia, Africa and the tropics.
A big part of choosing a wood floor is choosing which wood species you want. Obviously the way a floor looks is a big part of the decision process. However before you get locked into a particular type just based on its looks consider the other characteristics of wood too. The species of wood offers several variables that factor into a style or functional choice:
Natural wood can be stained however not all woods accept stain well and some are better off without it. Oak and maple accept stain well and offer numerous choices for colors. For example, if you like the color of cherry floors but maple better fits your budget you can purchase maple with a cherry stain.
Why is this important? Mainly because in some cases the physical characteristics of two woods that share a name are totally different. It's a matter of expectations -- if you're expecting the attributes of a North American cherry and get 'Brazilian Cherry', you may be surprised.
Some other common aliases you'll run across are Brazilian Walnut (actualy ipé, and no relation to American Walnut), Tasmanian Oak (in reality eucalyptus and no relation to oak) and Brazilian Maple (rather pau marfin, a South American hardwood).
Now it's not like there's a conspiracy out there among wood floor producers to fool the buying public. Rather, it's more like a system that's evolved over time that uses more familiar wood names to help with the identification process.
Red Oak Wood Flooring
So how do you avoid this name game and keep things straight? The best way is to dig a little deeper and ask or look for the genus name of the wood. For example, cherry's genus is "Prunus" and oak's is "Quercus". Each genus is subdivided based on the specific species within that classification. "Quercus alba" is White Oak and "Quercus rubra" is Red Oak. Finding out what the botanical genus name is for a particular wood should remove any mystery about what exactly it is you're dealing with.
One good place to go on the web that gives you that information is the Center For Wood Anatomy Research. The website is produced by the USDA Forest Service, Forest Products Laboratory. You can search for different wood species based on categories like North American hardwoods, tropical woods, etc. (look for the links that say "North American Hardwoods", "Tropical Hardwoods" and the like). There's also alphabetical breakdowns and the ability to search by common names. The information has a scientific 'read' to it but it's useful for sorting out species types and their characteristics.
Once you've become more familiar with wood flooring terms and species significance there are several points to consider in order make an informed buying decision.
Using non-certified flooring products doesn't mean you won't get a quality floor. It just means that with certified products, you can be assured of a standard of quality consistency for a particular floor product.
If the wood is manufactured and dried beyond what it will see in the home, it will absorb water and swell as it acclimates to that environment (picture a dry sponge as it swells in the presence of water).
The size of wood planks (along with species choice) will affect how much the board will expand and contract. Wider boards (such as wide-plank floors) will do this more than narrower strip planking. Combining this characteristic with a less-stable wood (beech for example) will magnify this effect. The result could be excessive gaps and/or cupping and warping of the boards when indoor humidity changes occur.
The bottom line here is that you should choose wood with these points in mind or work closely with the installer to understand just what you're getting. With less stable wood you may want to go with narrower planks to minimize the effects of shrinking and swelling.
Some exotic woods come from developing countries and areas that lack the controls for managed forestation. Illegal logging practices for woods such as Merbau threaten the existence of such species (ref. Greenpeace.org report "Merbau's Last Stand", April 17, 2007, http://www.greenpeace.org/international/news/merbau-s-last-stand).
One way to ensure the wood floor you choose isn't harmful to the environment is to choose products certified by the Forest Stewardship Council, an international non-profit, non-governmental organization committed to worldwide environmentally and socially responsible forest management. Products that are FSC certified carry the FSC trademark label which signifies that the wood was procured from forests managed in an environmentally and socially responsible way.
Wood floors aren't just basic oak strips anymore. There's something to entice just about anyone whether it be a convenience feature or a decorative effect.
Many floors incorporate aluminum oxide in the coating which is one of the hardest materials. This protects the surface of the wood more so than a typical polyurethane finish that you'd get with a site-finished floor.
Even more durable are the acrylic-impregnated woods. This process is actually used for commercial applications but Armstrong® Premier Performance™ engineered hardwood is suitable for homes. The acrylic fills the open pores of the wood to create a hard durable surface with increased resistance to dings and dents.
Engineered products allow some of these exotic woods to be made into floors by reducing the amount of actual wood that's needed. Rather than producing a 3/4" thick solid product, only the top surface is made from the "choice wood" and the rest of the thickness made from other wood types.
Logs that long ago sank to the bottom of rivers and harbors that once were the site of logging activity are being rescued and reworked into flooring material. Cold temperatures preserve the wood and prevent decay.
Want floors made from reclaimed wine barrels? Fonteny Woods offers two flooring products made from used wine barrels by deconstructing them and milling the wood into floor planks. One product showcases the surface that was the outside of the barrel complete with stamps and other markings. The other product highlights the surface that was the inside of the barrel reflecting the tones imparted by the red wine contents.
Intricate inlays of any design conceivable are available from different sources. Oshkosh Designs specializes in wood inlays that are made from both domestic and exotic woods (www.oshkoshfloors.com). Custom made floor medallions can be built to your specification by Czar Floors (www.czarfloors.com).
The cost of a hardwood floor will vary depending on a number of factors including finish type (pre-finished or unfinished), species (commonly available domestic or rare exotic), unique specialties (hand-scraped, reclaimed antique) and where you get it.
For general wood floors (not including specialty products like antique lumber, custom designs, etc.) the cost ranges anywhere from slightly less than a dollar per square foot (cabin grade utility oak) upwards to $20.00 per square foot for more exotic types like Wenge. These are uninstalled costs. Professional installation will add to the total price.
Despite the higher costs for some rare exotics most wood floors lie in the range of about $3.00 to $12.00 per square foot uninstalled.
There are numerous producers of wood flooring products that run the gamut from large manufacturers like Armstrong®, Anderson™, BR-111™ and Mohawk® to smaller companies and lumber mills.
Retail flooring centers and home stores usually carry products from the larger manufacturers and checking them out will give you a good start at seeing some actual product. Some internet retailers also carry some of the more recognized brands too.
The decision on where to buy is influenced in part by the type of product you want. If you want site-finished floors you can buy unfinished wood from a number of sources including local as well as internet retailers. Pre-finished wood is usually associated with the larger flooring manufacturers and is available from flooring retailers, home centers and internet retailers.
Specialty products like reclaimed and antique wood floors are found through specific dealer representatives or directly from the source. Using the internet to search for 'reclaimed wood floors' or 'antique wood floors' will provide a list of sources for these products. Their websites will indicate where their products can be purchased.
