One of the best Brazilian
hardwoods for decking, cumaru is an increasingly popular and in demand material
for different types of home improvement projects. This natural wood is known
for its hardness and durability, offering a lifespan of more than two decades.
Naturally biodegradable, cumaru is definitely a better material choice than
composites that many modern decking use.
Cumaru trees are a native
of the South American rainforest. Throughout their existence, these hardwoods
have naturally developed a strong resistance to rot and decay as well as to
insect infestation even well after they have been cut down. The resulting
material is an organic hardwood that can be relied on for at least 25 years
(free of preservatives). Cumaru is a highly renewable resource, growing at a
faster rate than other Brazilian hardwoods, including the popular yet expensive
Ipe wood. Because of this, many advocate for its use in construction
applications.
Cumaru is an excellent material for decking, fencing, and even for use as seating. Its natural
grain is one of the most noticeable and regarded features of this particular
hardwood. Itsrings and streaks can be further highlighted with all kinds of
stains, giving the wood an even more elegant glow. Cumaru ranges from a medium
tan hue to a deep reddish brown shade. These natural color variations serve
well to complement the wood's natural charm, making it an even more popular
choice for outdoor decking and indoor flooring applications.
Cumaru places high in the
Janka hardness scale (3540 lbf)—a significantly higher number than most other
hardwoods like oak and hard maple. This hardness also makes the wood highly
resistant to scratching. The natural habitat of cumaru trees exposes the wood
to all kinds of extreme weather conditions as well as swarms of pests, making
the wood naturally resistant to these elements even without much preservation.
