Which system is demountable?

• A. Modular wall systems
• B. KD door frames
• C. Glass block
• D. Hardened clay

Answer: (A)

Demountable partitions are designed to be taken apart and reassembled as space needs change. Modular wall systems use standardized panels, tracks, and connectors that can be disassembled without damaging the components, allowing them to be relocated, reconfigured, or reused with relatively little downtime. This makes them inherently suited to a demountable requirement.

Glass block walls, while sturdy, are usually set with grout or mortar; removing them tends to damage blocks and requires significant work to re-site or reuse them. Hardened clay is a solid masonry material that is not intended for easy disassembly. KD door frames are knock-down and can be taken apart, but the overall system most purpose-built for flexible, repeatable layouts is modular wall systems, which is why they’re the best fit for demountable needs.
