House siding isn’t exactly the kind of home improvement most people get excited about, but if you’re tired of trying to maintain warped and rotted wood siding, maybe you’ll be interested in some alternatives. Fiber-cement exterior siding is made from cement, sand, and cellulose fibers. It’s more durable than wood, and it usually comes with a 50-year warranty. Unlike wood, fiber siding doesn’t warp, rot, melt, or twist, and it’s impervious to termites. Also, fiber cement siding is more environmentally friendly than wood siding, since it reduces the demand for old-growth cedar or redwoods (the species usually used in wood siding). If you live in an area prone to wildfires, you may even be able to get a reduction in your homeowners’ insurance rates, since cement doesn’t burn like wood.
