Hardwood flooring is among the most popular floor types available today and has been for more than a century. Hardwood's
beauty and lasting value creates a combination that's hard to beat.
Hardwood is a good choice for many situations, but is it a green flooring choice? The answer is an unqualified maybe.
Don't worry. We're not going to leave you stranded in a forest of doubt. In this section, Green.FindAnyFloor.com™ will
lead you through the maze of information on green hardwood floors to help you identify the facts.
When is Hardwood Flooring an Eco–Friendly Choice?
Did you know?
- Hardwood flooring can be an eco–friendly floor covering when it's made with wood from responsibly managed
forest or from salvaged or reclaimed hardwood and emits low VOCs (including formaldehyde).
- Formaldehyde is like sunlight in that it is naturally occurring and our bodies cannot live without it, however, also
like sunlight, in high doses it is an irritant and possible carcinogen.
- SmartWood Certification Systems estimates that reclaiming a million board feet of lumber preserves a thousand acres
of old growth forest.
- In a recent survey by the National Wood Flooring Association, real estate agents agreed that a house with hardwood
floors would sell faster and for a higher price than the same house with carpet.
Wood is a natural, renewable resource, and can be recycled or reused in some situations at the end of its lifecycle. That
much is clear, but matters become more complicated from there. When determining the green value of a new wood product there
are many different factors to take into consideration. Some say the easiest answer is to buy only flooring certified by the
Stewardship Council (FSC). While the FSC is the most recognized sustainable forestry certification program, this does not
complete the equation to buying green hardwood flooring. There are many other factors to consider such as energy and other
materials used for manufacturing, fuel used for transportation, methods and materials used for installation, the level of
VOCs that the product emits, hardwood cleaning products used, and more.
When shopping for hardwood flooring you will see an array of different green certifications that certify green floors from
a number of different environmental angles. If you aren't prepared it can be difficult to know what to look for, as some
certifications are reputable as being greener than others. Our goal throughout these sections on green hardwood flooring is
to give you the tools and information you need to make an educated choice when buying green hardwood floors that are not only
environmentally responsible, but a health–friendly choice for your home or business.
First, let's look at the different kinds of hardwood floors – solid and engineered, which we will be covering
further in these sections on eco–friendly hardwood flooring.
Solid or Engineered – What is Right For You?
When you first begin to consider if hardwood flooring is the right environmentally conscious choice for your home or
business, you will need to determine if a solid or engineered construction is the best choice for your area of installation.
Solid hardwood – Solid hardwood strips and planks are made from solid pieces of wood. This wood can
be sawn in a variety of different methods including plain sawn (the standard sawing method), quarter sawn (which create
planks with superior stability), and rift sawn planks (which result in the most stable hardwood planks). Planks which are
considered "stable" stand up better to changes in humidity and temperature that those that are not. See photo below
for an example of the different methods of sawing.
Engineered hardwood floors – Engineered hardwood flooring consists of layers of wood (called plies) which are adhered
together and topped with a veneer. There are two major types of engineered hardwood constructions,
multi–ply (which has a plywood core consisting of 5 to 11 plies topped by a layer of finished wood,
called a veneer) and three–ply (which includes a balance sheet (layer of plywood) and a core layer
(usually solid wood), topped with a veneer layer.
There are some concerns about engineered hardwood floors being made with adhesives that contain formaldehyde (including
urea–formaldehyde) which is a possible carcinogen. Responsible flooring manufactures are now using
formaldehyde–free adhesives with low or no VOC's (volatile organic compounds).
Note: Formaldehyde is naturally occurring in all living organisms, including wood. It is in
the air we breathe, and the foods we eat, and is actually important to the metabolic process. However, in high doses it
becomes an irritant and a possible carcinogen, though studies are very conflicting on this matter. There are no
formaldehyde–free wood products, but there are manufacturers that take steps to ensure against adding additional
formaldehyde to their products, in order to avoid increasing formaldehyde levels to where they become an irritant or a health
Choosing the Right Hardwood Floor
There are times when engineered hardwood flooring is best, and other times when solid hardwood floors are preferred,
depending on the area of installation and one's lifestyle needs. Because wood is a natural product that can contract and
expand with changes in humidity and temperature, you have to be careful about not only controlling your indoor climate, but
also choosing the right hardwood flooring for your installation. For example, due to their multi–ply or
three–ply construction methods engineered hardwood flooring and floors made from stable wood species are more resistant
to expansion and contraction than others. For this reason, they may be safer for installation areas such as basements, which
may experience humidity from concrete moisture emissions, though proper moisture control measures must be taken according to
the manufacturer's recommendations (i.e. testing concrete floors for acceptable moisture emissions and using a moisture

Alternatives to Hardwood Flooring – Other Green Flooring Options
Hardwood flooring is easy to maintain, can last for decades, and in many cases, only gets more beautiful after time. If,
for some reason, you have decided that hardwood flooring is not the right green flooring choice for you, check out these
other green floor covering options:
- Cork: Durable, resilient cork flooring is
made from the bark of cork oak trees. The cork is harvested every 9 or 10 years without harming the trees, which can live as
long as 150 to 200 years, making cork a green sustainable floor choice.
- Bamboo: Made from one of Earth's most
rapidly renewable resources, bamboo can be harvested every 5 to 7 years and begins growing again immediately, without
cultivation. Eco–friendly bamboo requires very little in the way of fertilizer or pesticides, and is very efficient at
absorbing nitrogen and carbon–dioxide and producing oxygen, making it a very green floor choice.
