Fiber cement boards are a popular choice in modern construction for their durability, fire resistance, and versatility. However, when it comes to creative architectural applications — especially curved surfaces — many builders and designers ask the same question:
Can fiber cement boards be curved or bent?
When working with fiber cement boards, proper installation isn’t just recommended—it’s essential for the board’s long-term performance. One of the most overlooked yet crucial aspects of installation is whether or not to leave expansion gaps between the boards. So, do fiber cement boards need expansion gaps?
When selecting construction materials for homes, offices, or public buildings, fire safety is a top priority. This raises an important question: Are fiber cement boards fireproof?

Fiber cement boards are known for their strength, durability, and resistance to moisture and fire. But one common concern from contractors and homeowners is:
“Do fiber cement boards crack over time?”
The short answer: Yes, they can — but only if installed incorrectly or under extreme stress.
Let’s break down the reasons behind potential cracking and how you can prevent it for a long-lasting result.
When working on a construction project that involves wet or humid environments, water resistance is one of the most important factors to consider. Many builders and homeowners often ask:
“Is fiber cement board waterproof?”
The answer is clear: Fiber cement board is not fully waterproof, but it is highly moisture-resistant. This makes it an excellent material for areas exposed to humidity, splashes, or even consistent outdoor rainfall.
