For durable exteriors that look like wood, Powers turns to Hardiplank from James Hardie. “It does a far better job of simulating true clapboards than other products in its class,” he says. The fiber-cement siding resists rotting, cracking, and moisture. Each 12-foot plank is primed and sealed. Prefinished planks are also available.
