# Demountable Partitions: Walls You Can Move

> Demountable partitions are prefabricated wall systems — solid, glazed or mixed panels on a proprietary frame — designed to be taken down and reinstalled elsewhere rather than demolished. They trade a higher initial cost for the ability to reconfigure an office with little waste.

## Why it matters

Every drywall change is a demolition. For companies that reorganise often,
demountable systems turn that into a relocation, reducing downtime, waste and
the cost of the next change.

## How it works in practice

| | Drywall | Demountable |
| --- | --- | --- |
| Initial cost | Lower | Higher |
| Reconfiguration | Demolish and rebuild | Dismantle and reinstall |
| Waste | High on change | Low |
| Finish | Painted board | Factory-finished panels, glazing |
| Best for | Stable layouts | Changing layouts |

## Common mistakes

- **Choosing it for a layout that never changes.** The premium is not recovered.
- **Poor sealing at the head.** Sound travels through the plenum.
- **Crossing fire compartment lines** with a system not rated for it.

## Frequently asked questions

### When are demountable partitions worth it?

When layouts will genuinely change — growing teams, short leases, project-based work or floors reconfigured every few years. On a stable long-term layout, drywall is usually cheaper.

### Are they as good acoustically as drywall?

Good systems can perform well, but acoustic performance depends on the specification and especially on sealing at the ceiling and floor. Rooms needing confidentiality must be detailed carefully either way.
