Carlisle’s Eastern White Pine and Longleaf Heart Pine floors each have unique histories as traditional American flooring materials. The former was the choice of the early New England colonists, who took advantage of its easy availability not only for flooring, but also for structural timbers and siding. The latter was the strong, tough building material used throughout the Southeast and Eastern Seaboard in the 1800s, earning the moniker “the wood that spawned the American Industrial Revolution.”
