In terms of impact resistance, fiber cement siding is significantly superior to vinyl siding. This difference is due to the fundamental composition and thickness of the materials.
Here is a detailed comparison, focusing particularly on resistance to weather phenomena like hail:
Impact Resistance Comparison
| Feature | Fiber Cement Siding | Vinyl Siding |
| Material Composition | Made of cement, sand, water, and cellulose fibers. The thickness and solid nature provide high strength. | Made of PVC (polyvinyl chloride) plastic resin. It is generally thinner and more flexible. |
| Overall Impact Resistance | High Impact Resistance. It is much stronger and tougher. It is designed to resist damage from accidental impact, fallen debris, and scrapes. | Moderate to Low Impact Resistance. While modern formulations have improved, it is generally considered weaker against strong impacts. |
| Hail Damage | Highly Resistant. Fiber cement is known for withstanding hail damage. It is an excellent choice for hail-prone areas. Damage is less likely to occur. | Highly Susceptible. Vinyl is easily susceptible to cracking, splitting, punctures, and dents from hailstones, especially in severe storms. |
| Cold Weather Performance | Maintains Stability. Quality fiber cement (like James Hardie’s products for cold climates) is engineered to endure freeze-thaw cycles without breaking and retains its shape. | Becomes Brittle. Vinyl becomes less flexible and more brittle in very cold temperatures, which significantly increases its risk of cracking or breaking upon impact. |
| Thickness | Generally thicker, which contributes to its enhanced durability and impact absorption. | Typically thinner, which makes it more susceptible to damage from forceful impacts. |
Key Takeaways on Durability
- Fiber Cement: Offers high impact resistance, making it an excellent, long-lasting choice for homes in areas with severe weather conditions, including hail, high winds, and strong temperature fluctuations.
- Vinyl Siding: While an affordable and low-maintenance option, its plastic composition makes it the weaker choice against physical impact and extreme temperatures, often leading to cracks, splits, or dents from hail or debris
