Eastman has introduced Perennial Wood porch flooring. The tongue-and-groove flooring is modified through TruLast Technology, which makes the wood more dimensionally stable than unmodified wood and resists moisture-induced changes. Several profiles are available: 3/4- by 3 1/8-in. finished face in 8-, 10- and 12-ft. lengths and 7/8- by 3 1/8-in. finished face in 8-, 10- and 12-ft. lengths. Select markets have available 7/8- by 4 7/8-in. finished face in 8- and 10-ft. lengths.
