fiber cement siding Panels Are Man-Made Rock

fiber cement siding panels are excellent materials to cover the exterior of a home. There are thousands and thousands of homes and businesses that have this magic siding on their exterior walls.

The panels are so weather resistant for many many years special ones were made as roofing shingles! The panels used to be made with:

• Portland cement
• fine silica sand
• fiber

It's important to realize all three of those ingredients are rock or derivatives of rock and water causes no harm to any of them.

Modern fiber cement siding panels contain wood fiber in place of the asbestos. Wood fibers in fiber cement siding absorb water. A point often overlooked is this water can freeze and expand in cold climates.
