Find product details below for our Hardwood Decking offered in Cumaru, Brazilian Teak in 1x4, Clear Grade from Nova.

For close to ground applications, use 4" nominal material, never 6" nominal boards. We never recommend hardwood with less than 16" of clearance below the deck. Good airflow beneath the deck is critical for ventilation - we recommend a minimum of 50% open areas.

Cumaru, Brazilian Teak Type Information

Cumaru, commonly called Brazilian Chestnut, is a tough and dense wood imported from Brazil that has an irregular, somewhat interlocked grain and wavy, course texture. Because of its density, it is very resistant to termites and decay. Cumaru's heartwood is a medium brown with distinctive tan shades that compliment one another in with tonal warmth to create a relaxing feeling that's great to come home to.
