Why Mastic Performance Siding is Better Than Fiber Cement

Fiber cement siding is often touted as low-maintenance and long-lasting. But unfortunately, it isn’t as great as people think. However, there are better options out there, such as the Mastic performance siding by Ply Gem®.

Learn more about this siding material as Harmony Home Improvement, a trusted company with professional siding and deck contractors, lists the advantages of Mastic performance siding over fiber cement siding.

Wind Resistance

It’s essential for the siding not to flap or gap in the wind. Mastic performance siding is nailed to the top and locked at the bottom, so you won’t have to worry about the boards coming loose. Fiber cement siding, on the other hand, only attaches at the top offering weaker resistance to wind. Nailing the fiber cement siding at the bottom isn’t recommended as this may cause the siding to crack or break.


A popular myth about fiber cement siding is that it doesn’t require repainting. While the color on fiber cement siding can last for years, fading will still eventually occur and you’ll have to repaint your siding. For Mastic performance siding, its color is already in the product and not layered on top of it. That’s why you won’t have to worry about weathering, chipping, or peeling. You may already be installing replacement windows, but your siding still looks great even after several years.

Water Resistance

Mastic performance siding is made from high-performance polymer that does not absorb even a single drop of water. This assures you that your siding will be safe from water infiltration or moisture. Fiber cement siding, however, absorbs water. This can eventually result in cracks, where water can penetrate, making your home vulnerable to rot, crumbling and disintegration.
