About Ipe

Ipe (pronounced "ee-pay") is widely considered the gold standard in premium hardwood lumber. Also known as Brazilian Walnut or Ironwood, Ipe is one of the densest and hardest commercially available woods in the world. Its extraordinary Janka hardness of 3,680 lbf — nearly three times harder than White Oak — gives it unmatched resistance to dents, scratches, and wear. Ipe's natural oils and extractives make it inherently resistant to rot, decay, mold, insects (including termites), and even fire, earning it a Class A fire rating equivalent to concrete and steel. Ipe has been used for decades on the boardwalks of Atlantic City, Coney Island, and commercial piers worldwide, proving its longevity in the most demanding environments. Whether used for decking, siding, flooring, or heavy construction, Ipe delivers a 25-75 year service life with minimal maintenance.

Key Characteristics

  • One of the hardest woods in the world (3,680 lbf Janka)
  • Class A fire rating — same as concrete and steel
  • Natural resistance to rot, decay, mold, and insects
  • Exceptional dimensional stability
  • Can sink in water due to extreme density
  • Weathers to silver-gray patina if left untreated
  • No chemical treatment required
  • Proven 25-75 year service life

Common Applications

  • Premium residential and commercial decking
  • Boardwalks, piers, and docks
  • Exterior siding and cladding (rainscreen)
  • Heavy-duty commercial flooring
  • Marine construction
  • Outdoor furniture and benches
  • Bridge decking
  • Pool surrounds and rooftop decks

Maintenance & Care

Ipe requires virtually no maintenance for structural integrity. It can be left completely untreated and will weather to a beautiful silver-gray patina over decades. To maintain the rich brown color, apply a UV-protective penetrating hardwood oil 1-2 times per year. Clean annually with mild soap and water. Never pressure wash above 1,200 PSI. Ipe will not rot, split, or decay even without any finish applied.

Advantages

Unmatched durability — outlasts every other decking wood
No chemical preservatives needed
Fire resistant (Class A rated)
Proven on high-traffic commercial installations
Extremely low lifecycle cost despite higher upfront price
Beautiful rich color and smooth finish
Resists scratches, dents, and heavy foot traffic
Suitable for ground contact and marine applications

Considerations

Higher upfront cost (offset by 25-75 year lifespan)
Extremely hard — requires pre-drilling and carbide-tipped tools
Very heavy (69 lbs/ft³) — difficult to handle
Can dull standard saw blades quickly
Natural oils can make gluing challenging
Color darkens with UV exposure
Limited to tropical sourcing (look for FSC-certified)
Requires stainless steel fasteners

Installation Considerations

  • Always pre-drill pilot holes — Ipe will split without pre-drilling
  • Use carbide-tipped saw blades and drill bits (standard steel dulls quickly)
  • Allow 1/8" gap between boards for drainage and expansion
  • Acclimate boards on-site for 5-7 days before installation
  • Use hidden fastener systems or face-screw with stainless steel
  • Joist spacing: 16" O.C. for 1x6, 24" O.C. for 5/4x6

Fasteners & Tools Required

  • Stainless steel screws (305 or 316 grade) — required
  • Carbide-tipped drill bits for pre-drilling
  • Hidden clip systems (Ipe Clip, Tiger Claw, Camo)
  • Countersink bits matched to screw head diameter
  • Stainless steel joist hangers for framing connections
