Well, it’s not so much that it’s better than pine but in this application, it lasts much longer when properly pre-finished. Did I mention Pella Window Company offers Poplar Wood as an upgrade to their standard Pine windows? They’ve been around for almost 100 years, so I think they set a good standard. We use solid full-length Poplar Wood rather than engineered, finger jointed Ponderosa Pine which is what Rockwell used. Poplar is known for its resistance to decay and insect infiltration. Pine has proven to fail in five years or less in some cases. Yellow poplar also known as Liriodendron tulipifera is most common and is found in the Northeastern part of the USA as well as Canada. This is considered a deciduous tree. The difference between a hardwood and a softwood is the seed. Hardwoods are angiosperms, which means the seed is encased in hard shells. Conifers are gymnosperms and have no seed coverings.
How strong is Polar wood? Very strong indeed to lateral and horizontal stresses as well as solar pulsing. But it’s not as hard as most hardwoods, with a hardness rating lower than that of some species of cedar, which is considered a softwood. The hardness of wood and the rating it achieves is determined by compressing a 1/2″ steel ball into a sample of the wood. Poplar scored 540 lb.-ft. This is higher than most softwoods. However, this number is below most other hardwoods and even some softwoods, such as fir and cedar. If you’re wondering whether poplar wood is furniture durable the answer is yes! Especially because poplar has incredible resistance to rot and insect damage.
