How to Choose the Right Fiber Cement Board Thickness for Partition Walls

Creating room dividers does not always require brick walls. Today, fiber cement boards are a popular alternative for partition walls because they are relatively easy to install and support lightweight construction.

However, did you know that fiber cement board thickness can significantly affect the final result of a partition wall? Choosing the wrong thickness may result in a wall that feels less sturdy or does not meet the room's requirements.

So, how do you determine the right fiber cement board thickness? Check out the following guide!
 

What Is Fiber Cement Board for Partition Walls?

Fiber cement board is a building material made from a mixture of cement and reinforcing fibers. It is used for various construction applications, including ceilings, wall cladding, and room partitions.

Simply put, fiber cement board works like a partition panel installed on a dedicated frame to divide a room without having to build a brick wall.
 

What Fiber Cement Board Thickness Is Suitable for Partitions?

Fiber cement boards are available in several thickness options. To help you choose, here are some examples you can use as a reference:

1. 6 mm Thickness
Can be used for certain applications that require relatively lightweight boards. However, when used for partition walls, installation must follow the product recommendations and use a suitable framing system.

2. 8 mm Thickness
One option for interior partition walls. For example, KalsiPart 8 is specifically designed for room partition applications.

3. 9–10 mm Thickness
Can be considered for partition walls or other wall applications that require different board specifications. Make sure the application follows the manufacturer's instructions.
 

4 Tips for Choosing Fiber Cement Board Thickness for Partition Walls

To avoid choosing the wrong material, consider the following factors:

1. Match the Thickness to the Room's Function

A bedroom partition has different requirements from an office divider or a partition in a commercial area. Consider the activities and frequency of use in the space.

2. Consider the Wall Height

The taller the partition, the more important it is to consider frame strength, spacing between profiles, and board thickness to maintain structural stability.

3. Consider Environmental Conditions

For damp areas such as kitchens and bathrooms, choose boards with specifications suitable for those conditions. Also, pay attention to the joint system and water protection measures.

4. Pay Attention to the Framing System

Fiber cement boards do not work on their own. The metal frame, installation spacing, screw type, and jointing techniques all contribute to the strength of the partition.
