Ipe hardwood for exterior applications
What is it? Also called Brazilian walnut, ipe (pronounced ee-pay) wood is typically found in South America and some parts of Central America. It is one of the densest hardwoods available, three times harder than cedar. Ipe has the same fire rating as concrete and steel, meaning it resists flames much longer than softer woods, and is so dense that it doesn't float in water.
How is it used? Because of its durability, ipe wood often is used outdoors as decking and siding. Inside, it's typically seen in flooring or cabinetry. For indoor use, the wood has to be kiln-dried to remove moisture, which keeps it from warping or cracking, says Scott Zubrow, architectural specialist at General Woodcraft in New London, Conn.
Ipe wood lasts a minimum of 25 years, although many architects say it can last up to half a century bugs out; it's resistant to mildew and decay, making it ideal for coastal construction. Ipe wood lasts a minimum of 25 years, although many architects say it can last up to half a century if maintained properly.
Cons Holes must be predrilled for screws. Its high oil and tannin content makes it difficult for paint to adhere. The hardness makes it unsuitable for intricate woodworking.
