Ipe, often referred to as Brazilian Walnut, is renowned for its incredible toughness and durability. It is extremely dense, which makes it resistant to rot, decay, and insect infestation. Ipe’s tight grain and natural oils prevent moisture absorption, making it an excellent choice for wet and humid climates. Ipe is hands down the best weather resistant wood we’ve come across and it’s one of our top sellers.

  • Benefits: Ipe is extremely durable and resistant to rot, insects, and weathering. It’s ideal for decking and outdoor flooring.
  • Lifespan: Ipe has proven to last up to 70 years outdoors on commercial applications such as the Coney Island boardwalk.
  • Janka Hardness: 3,680 lb

2. Teak
