Core Ipe Advantages
Every benefit below is backed by standardized testing data — not marketing claims.
75+
years
Up to 75+ Year Lifespan
Ipe outlasts cedar (15–30 yrs), composite (15–25 yrs), and pressure-treated lumber (10–20 yrs) by a wide margin. Many Ipe boardwalks installed in the 1960s remain in service today.

lbf
Janka Hardness: 3,684 lbf
Nearly 3× harder than White Oak and over 10× harder than Western Red Cedar. Resists scratches, dents, and heavy foot traffic without damage.
Class A
ASTM E84
Class A Fire Rating
The highest fire rating available for building materials—comparable to steel and concrete. No chemical flame retardants needed. Ideal near fire pits and in wildfire-prone regions.
15 yr
US Navy test
Natural Insect Resistance
The U.S. Naval Research Laboratory buried Ipe underground for 15 years—it resisted all termite attacks for the entire period. No other wood duplicated this result.
Class 1
durability
Rot & Decay Proof
Ipe achieves Class 1 (highest) durability rating. Natural oils and density create an internal moisture barrier that functions for decades without treatment.
Very
stable
Dimensional Stability
Minimal warping, cupping, or twisting compared to softwoods. Interlocked grain pattern resists seasonal movement and maintains flatness over decades.
Proven by Science
The U.S. Naval Research Laboratory buried Ipe underground for 15 years to test termite resistance. It resisted all termite attacks for the entire period. No other wood species has duplicated this result.
Additional durability data is documented by the USDA Forest Products Laboratory.
