CUMARU

ELITE GRAIN FOR ELITE TASTE

You simply know when you’re standing on a board of Cumaru. An exceptional hardwood, with endless qualities, it is considered one of the best species of lumber for exterior home renovation projects. Its strength also makes it a preferred wood for flooring, cabinetry, furniture, and more.

ITS ROYAL STATUS IS BASED ON:
  • Its excellent durability makes it very resistant to decay.
  • The long lifespan of over 50 years.
  • Its stiffness, strength, and extreme hardness make an ideal choice for a multitude of different projects.
  • Its resistance to insects, rot, and fungi makes it an excellent choice for outdoor use.
  • Its great value for those seeking low-cost lumber with excellent strength and hardness properties.
  • Peace of mind knowing that Cumaru has a Class A rating for fire resistance that is comparable to that of steel and concrete.
  • If all of that isn’t convincing enough, Cumaru typically has a scent of cinnamon and vanilla when being worked on.
