Mineral wool wall sandwich panel, 20 cm thick, grade 2

Buildings with enhanced fire requirements can still benefit from prefabricated envelopes. Mineral wool sandwich panels combine a non-combustible core with protective facings. They make it easier to create insulated walls with an attractive surface, both for new halls and for separating individual areas within them.

Mineral wool allows envelope systems to be designed for applications where fire performance is important. The core is already enclosed between facings, so it does not need a separate covering across the entire wall. This helps combine technical requirements with steady construction progress. Fire resistance is determined for the particular panel and the way it is fixed and joined. A system can therefore be selected for the function of the separated area, with the verified detail repeated across successive bays.

The fibrous core reduces heat transfer through the panel. This is useful in heated production buildings, technical rooms and work support areas. Insulation within the prefabricated element maintains a defined thickness across its surface. It is therefore easier to create a repeatable assembly throughout the façade. Where noise control is also required, the acoustic properties of the particular version and all junctions can be assessed. Limiting temperature fluctuations through large walls is especially noticeable at workstations close to the external envelope.

The outer sheet gives the building its colour and profile, while the inner facing creates a consistent interior. This reduces additional plastering or lining work. In a plant with extensive wall areas, it means fewer separate finishing stages. Smooth or lightly profiled facings help maintain a unified interior. Matching the coating to operating conditions lets the surface suit a workshop, warehouse or commercial space without changing the core construction. Repeating bays and suitable flashings make connections to doors and windows easier. The façade can then form a considered part of the hall’s architecture.

Mineral wool versions can form external and internal walls and, where specifically designed for the purpose, ceilings. A similar material standard can therefore be maintained across several building zones. Installation on a frame allows panel positions to follow structural axes and openings. A mineral core weighs more than a foam core, which must be considered when selecting supports and handling methods. In return, the investor receives a prefabricated partition combining mineral insulation with a finished usable surface.
