DECKING
TECHNICAL DATA

Hardness: An Ipe Black Label deck is approximately three times stronger than teak and eight times harder than California Redwood, tested under ASTM-D143.

Expansion and Contraction: Approximately 5.9% radial, 7.2% tangential, and 12% volumetric. A 6” air-dried board will move an average of 1/16”. There is a small movement after milling as well.

Fire resistance: In Canada, the Ipe Black Label decking board has passed the Intermittent Flame Test and The Spread of Flame Test for the CAN/ULC S107 equivalent of ANSI /UL 790 (Standard Methods of Fire Tests of Roof Coverings) and is rated Class A. This makes it suitable for a rooftop finishing material in non-combustible building class buildings, putting it in the same class as steel. In the U.S., Ipe Black Label wood has been tested by the National Fire Protection Agency, which gave it the highest Flame spread classification: Up to Class A, Uniform Building Code, Class 1.

Termite resistance: Ipe Black Label has received the highest rating from the U.S. Naval Research Laboratory.

Durability and longevity: Untreated Ipe Black Label decking will last 40 years and more. If the deck is oiled or finished on all four sides before installation, it can last 70+ years.
