Lapacho Ipe Hardwood Technical Species Information

Detailed scientific and mechanical properties for Lapacho Ipe Hardwood Lumber


  • Description: Lapacho, a Paraguayan Ipe, is an incredibly durable wood. Its dense cell structure serves as a natural deterrent to insects, decay, and molds. Because of this natural resilience Ipe is often the first choice for decking because of its almost unparalleled ability to stand up to the elements. More than just durable, Ipe is also very pleasing to the eye. Its heartwood is light to dark olive brown with contrasting yellowish-grey or grey brown tones accompanying it. With a Class A fire rating, Ipe occupies the same class of fire-retardant materials as steel. For durability, safety, and beauty, Ipe makes an excellent choice.
