The most common test for testing wood hardness is known as the Janka hardness test. The actual number listed in the wood profile is the amount of pounds-force (lb f ) or newtons (N) required to imbed a .444″ (11.28 mm) diameter steel ball into the wood to half the ball’s diameter. While most people would be looking for the hardest wood, just out of curiosity, here’s a list of the ten softest woods on the site. Keep in mind that five out of these ten woods (including the three softest) are considered hardwoods. This just goes to show that the terms hardwood and softwood merely refer to the botanical classification of the trees as either conifers (softwoods) or angiosperms (hardwoods). There’s no guarantee that any given hardwood will actually be hard! Note: A hardwood named Quipo (Cavanillesia platanifolia) is commonly reported as the softest known wood, with an alleged Janka hardness of 22 lb f (98 N). However, the wood is omitted from this list for two main reasons. First, it is virtually unobtainable and not commercially available outside of its natural range in Central/South America. Secondly, the purported hardness seems highly questionable, especially in light of the fact that Quipo seems to be very susceptible to rot, and on one USDA test, it was remarked that “the results for quipo may have been influenced by the presence of considerable decay.” Furthermore, when comparing Quipo with Balsa, it has been shown that the two woods are virtually identical in hardness, with the absolute lowest recorded Janka hardness values, in the range of 20-35 lbf (89-156 N), were actually from Balsa, and not Quipo.

Are you an aspiring wood nerd?

The poster, Worldwide Woods, Ranked by Hardness, should be required reading for anyone enrolled in the school of wood nerdery. I have amassed over 500 wood species on a single poster, arranged into eight major geographic regions, with each wood sorted and ranked according to its Janka hardness. Each wood has been meticulously documented and photographed, listed with its Janka hardness value (in lbf) and geographic and global hardness rankings. Consider this: the venerable Red Oak (Quercus rubra) sits at only #33 in North America and #278 worldwide for hardness! Aspiring wood nerds be advised: your syllabus may be calling for Worldwide Woods as part of your next assignment!

How long does it take a wet 2x4 to rot?

Wood can Start to Rot in 1-6 months If: Wood is untreated. The wooded area is sitting in water. Water and/or air space is hot & humid. The area is at or near the ground.

Is water coming into your home? A well built house with the right framing and expertise is surely not capable of withstanding the true forces of nature. Depending the type of wood installed, whether if it’s in the framing, siding, soffit, fascia, or decking, rotted wood is never something that should be ignored. Over time, rotted wood can pose a serious health hazard if kept untreated for a long time. Rotted wood can start to degenerate and lose it’s strength, making your home vulnerable to future damage. The best way to prevent your wood siding, framing, soffit, or fascia from rotting is to first take preliminary steps beforehand, but if you’re on this page, then it is most likely that you already have rotted wood, so let’s first identify the rot and fix the issue before you have this:
