Bamboo Floors From Harvest to Flooring
A common error some make about bamboo is that it is a type of hardwood. Not to
be confused with common associations of many species of grass, bamboo is
actually a type of grass which matures into a material that can rival the
hardness of maple! Being well adapted to the environment in which bamboo
commonly grows, each bamboo plant thrives in areas of fair to poor soil
quality, and still remains to be one of the fastest growing plants in the
world. Controlled harvesting of the bamboo plant has very little impact on each
individual stalk, which will continue to grow long after harvesting. This is
what makes bamboo such a renewable source of flooring material, and why it is
often associated with environmentally minded choices for flooring. The fact
that it is such a uniquely attractive flooring option makes bamboo flooring an
extremely beneficial choice for your own interior environment!
How Bamboo Flooring is Made
Once the bamboo has been harvested, the outer layer of green "skin" is removed
and each stalk is cut into lengthwise strips or "fillets". These curved fillets
of bamboo are milled along their outer edges in order to flatten them. The
excess elements of this process will go into another type of bamboo flooring
that is called "strand-woven bamboo flooring" - more on that later. The
flattened strips of bamboo are then kiln dried in order to remove the natural
moisture in the bamboo, and are then boiled. The bamboo fillets are now ready
to be glued together to make a solid, dependable surface that is more than
suitable for flooring. The bamboo undergoes one final compression stage, which
makes it that much more durable and ready to ship. Tongue and groove elements
are added in order to make an installation as easy as possible. It should be
mentioned that the outcome of this manufacturing process is dependent on which
kind of bamboo flooring is being made. There are several types of bamboo
flooring, both in terms of cut and of color, and some differences in how they
are processed.
Horizontal or Vertical Bamboo Flooring
During the gluing process, the bamboo can either be bound with the narrow edges
facing up, which results in a thin, channel pattern in the bamboo flooring, or
so that the broader surface of the bamboo is bound facing upward, making for a
surface that is more akin to traditional hardwood patterns. These styles of
bamboo flooring are known as vertical and horizontal bamboo flooring
respectively. There are visual benefits for each one, depending on your
personal taste, but both remain to be decorative choices. The horizontal style
is striking for its "knuckle" or "node" patterns, that is, the pattern
naturally occurring in the bamboo that are the equivalent of "growth rings" in
many hardwood species. The vertical style is a unique surface that remains
unmatched by any other natural flooring material, characterized by decorative,
narrow channels caused by the binding of the bamboo strips. There is very
little wastage of materials during the bamboo flooring manufacturing process,
making bamboo a truly renewable and sustainable source of flooring materials.
