Cumaru is a tropical hardwood native to Brazil, also known as Brazilian teak. It is one of the densest and most durable natural wood species available for exterior cladding. Cumaru is naturally resistant to rot, decay, and insect damage, which makes it an excellent choice for exterior siding even in the hot, dry climate of Las Vegas. The Rio Vista Estate uses Cumaru wood siding imported directly from Brazil, giving the home a warm, natural exterior that is rarely seen in the Las Vegas valley.
