Reclaimed Wood Diaries: Adventures In Sourcing Part II - Dinizia

Tough as nails, greener than Ipe:  The story of reclaimed Dinizia

It started with a notice from one of our sourcing partners in the Midwest: a tropical hardwood sound barrier was being removed to widen a highway in the Chicago area, and the contractors needed to dispose of it.  Specializing in reclaimed and sustainable wood flooring, cladding & tables, Anthology Woods is always looking for high-quality and unique woods ready for a second life, and the silver-gray weathered patina was beautiful.  Once we had a sample in hand, the discoveries started:

Our wood anatomist determined it to be Dinizia excelsa, a Brazilian native prized for impressive durability, hardness, and resistance to insects & decay.

After 40 years exposed 24 hours a day, 365 days a year, the wood was in amazing shape – only boards with direct ground contact showed any significant decay.

The fasteners were going to be labor intensive to remove, but we could work with it.  Milling costs would be a bit higher than that for most of our products because of the hardness, but it machined smoothly and finished well.

Beyond the stunning silver-gray patina that would be gorgeous on walls, the wood underneath could be used for decking, flooring, and siding.  The rich wood color was similar to Ipe, and performance was similar to Ipe, as well.  We fell in love with the rich color streaking and interlocked grain patterns.

The Dinizia wood polishes to a rich soft sheen (ironic because it is so hard!).

The verdict?  We took the plunge with this distinctive and rare tropical wood and bought every board we could track down – and have now created a line of decking, siding, flooring, and wall cladding around it – and even built table tops with it, too!  For a limited time, Dinizia will offer a very sustainable alternative to Ipe in applications where hardness and durability are critical.

The best sustainable woods for exterior siding and decking

What are the top sustainable wood choices for outside?

Anthology Woods is receiving increasing inquiries about the best woods to use for decking that will have long-lasting durability and a beautiful look while protecting our environment.  The same species selected for Decking also make excellent choices for exterior siding in classic and rain screen applications, as well as soffit cladding.  We've compiled a quick list of your best bets in terms of beautiful woods excelling in exterior durability & sustainability.

As we discussed in a previous post, the immense market demand for newly harvested tropical hardwoods for exterior applications has caused unprecedented deforestation in the Amazon Basin and elsewhere in the world.  It's no wonder these woods are desirable - tropical hardwoods stand up exceptionally well to the cycles of sun, wind, rain and repeated abuse.  Luckily, there are a few post-consumer reclaimed options (meaning the wood is entirely recycled from a previous use, and no trees are currently being cut to provide for your project)!  You can either opt to finish your reclaimed tropical hardwood with an exterior finish or to leave it unfinished and allow it to weather.  Finished wood will always last longer, regardless of species.

  • Reclaimed Sakhay Teak is a premium old-growth Teak reclaimed from vintage structures in Southeast Asia.  The rich brown color tones & lively grain of Teak are distinctive to this species, and the natural oil & silica content in the wood makes it an exceptional choice for exterior projects.

  • Reclaimed Dinizia is originally from Brazil, with rock-hard density, extreme durability and excellent resistance to decay and insects.  Along with Teak, Dinizia is in the class of woods that can last for decades outside.

With a Reclaimed tropical hardwood you are getting the ultimate:  the best sustainability and the best durability.  Your reclaimed wood comes with reclaimed character to testify visually to your part in preserving our planet, too!


Domestic species from reclaimed sources are very sustainable, though they are not in the same A+ class for long-lasting durability as the tropical woods are.  Species like Redwood & Cedar are suitable for decking and siding, and Fir is often used in soffits or on siding with an exterior finish.  Unfinished Fir will age rapidly, though it is used frequently in the northwest. 

This house has reclaimed cedar siding and reclaimed  Grandstand Fir  soffit with a matte clear finish to protect the wood. The deep overhangs also provide shelter to extend the life of this installation.

Another great source can be salvaged or sustainable harvest woods.  Anthology Woods has begun working with partners to bring salvaged and sustainable woods to market including domestics like redwood & cedar, and tropical Mahogany.  Sources include urban, industrial, water or forest floor salvage, or in some instances, wood from sustainably managed forests.  These are often excellent woods in terms of lasting service & beauty, though they seldom match the sustainability of a truly recycled wood, and rarely have as interesting of a story.  Their advantage is often longer & more consistent lengths than are common for reclaimed woods.


Please contact Anthology Woods with any questions about sustainable decking, siding, or soffit wood and we'll be happy to support your project with our expertise & wide range of options!

Using Reclaimed Tropical Wood Can Help Prevent Deforestation

A recent story by ABC News reports that as many as half of Amazon rainforest tree species may be on the verge of extinction due to deforestation.  The study, published in Science Advances, finds that depending on the degree to which deforestation comes under control in the next 35 years, between 36 and 57 percent of the 16,000 tree species in the Amazon rainforest would be considered threatened.  The study, which can be read here, goes on to state that some tree species including mahogany are already "commercially extinct."

A good alternative to commercially harvested tropical woods such as Ipe or Mahogany is Reclaimed wood from Anthology Woods. Anthology Woods specializes in tropical species like Teak and Dinizia, and we are constantly on the lookout for other rare or exotic species to help fill the need for durable, beautiful and sustainable wood products.

While Ipe and Reclaimed Dinizia exhibit similarities in appearance, hardness, and durability, they are wildly different in terms of sustainability:

IPE VS. DINIZA: Sustainability & Sourcing


Ipe is logged from the rainforest.  Ipe occurs just once per 300,000 to 1,000,000 square feet, and many other trees are typically cut to clear a path to the valuable Ipe.

FSC certified Ipe has become scarce, pulling into question whether any kind of sustainable management is possible for this species.

Ipe is not readily available as a recycled material.  The Ipe currently on the market is from newly-cut trees, and sustainable management/harvest cannot be guaranteed.  It is estimated that 80% of Ipe is harvested illegally 


Reclaimed Dinizia is 100% FSC post-consumer recycled.  You can see the nail holes and rich color patina from previous use, and our reclaiming process is well-documented with photographs from the original structures. 

There is absolutely no question regarding the genuine sustainable nature of reclaimed Dinizia. 


  • Available milled to order in siding, decking & more.

  • Average length is approximately seven feet -- much longer than most reclaimed inventories.

  • Custom millwork and lengths for herringbone or checkerboard decking layouts is available.

  • Price is comparable to FSC Ipe, and the cost to our planet is infinitely lower.

Please contact Anthology Woods for your reclaimed tropical hardwood project needs in decking, siding and landscape applications.  Anthology Woods also custom sources the finest reclaimed Teak flooring, siding, decking and wall paneling, too.

Amazon warriors fight illegal logging of tropical hardwoods

Deforestation threatens way of life for people native to the Amazon basin - and they are fighting back:

You and I aren't the only ones concerned with the deforestation of tropical hardwoods due to illegal logging (this video from the Sierra Club estimates 30% of global logging is still illegal):

NBC shared photos last week of Amazonian warriors taking back their land from illegal loggers. The Ka'apor Indians have had enough of their government providing inadequate protection of the land, and are taking matters into their own hands - expelling loggers from the area and setting up watch areas.  View the images here (warning, violence depicted).

Connect with Anthology Woods for reclaimed alternatives to illegally harvested tropicals (such as reclaimed Rosewood, pictured below).  Your choice of reclaimed is a meaningful step in reducing rainforest decimation, even in spite of widespread corruption and phony "sustainability" documentation.  Reclaimed wood has nail holes and character from decades of use that testifies to a truly recycled nature you can see for yourself.
