Degradation of Fiber Cement Siding

Degradation Of Medium-Density Fiber Cement Siding

Fiber cement cladding has found wide acceptance as a durable and renewable material.   Since entering the U.S. market in the early 1990s, assumptions on its long-term resiliency have relied heavily on wet/dry cycling tests, but little is reported on its durability under typical in-service conditions.   Here we describe four stages of fiber cement degradation under…
