Reported to be somewhat slower growing than the species, and more tolerant of summer heat and disease. Like the species, it is resistant to the bronze birch borer, and is both longer-lived and more heat tolerant than the white-barked birches.

"Dura-Heat" is a proprietary tradename. The true cultivar name is 'BNMTF'.
