A hollow partition made with cement fiber board typically consists of two fiber cement boards placed with a hollow gap or air space in between, often supported by a metal framework such as metal furring channels. This hollow gap acts as a thermal insulator because the air trapped inside reduces heat transfer through the wall. However, this hollow space can also cause sound to reverberate and transfer between rooms, which can be mitigated by filling the gap with insulating materials like wool or aluminum foil to dampen sound and improve thermal performance.

Fiber cement boards used for partitions offer advantages over concrete hollow blocks, such as better thermal insulation due to the air gap, faster installation, cost savings on labor, and a flat surface that makes patching and painting easier. These boards are generally lighter and cheaper to build with while still providing durability.

For structural usage, such as in prefabricated cabins or porta cabins, thicker fiber cement boards (like 18mm to 40mm) can be used as load-bearing panels when adequately supported by steel framing beneath. However, their use as load-bearing members requires consideration of thickness and structural support to handle the load effectively.

In summary, hollow partitions in cement fiber board involve a dual-layer board system with an air gap or hollow space that provides insulation benefits while requiring noise control measures if soundproofing is desired. These partitions are popular for their cost-effectiveness, ease of installation, and thermal properties compared to traditional concrete block walls.
