Advantage Cumaru™ (pronounced ku-mah-roo) is an incredible, low-maintenance hardwood that offers a beautiful array of amber-red to golden-honey colors. Each board of premium-grade Cumaru is also naturally resistant to rot, decay, and insects. This exotic specie rivals Ipe in strength and nearly 8 times harder than redwood. With a lifespan of well over 50 years, you will enjoy your Cumaru deck for decades. With such strength and beauty—and up to a class A fire rating—an Cumaru deck is an investment that’ll increase your home’s value.
