A11-C

Radiant metal ceiling

The A11-C radiant heating and cooling ceiling is suitable for rooms with high heat loads and enables draught-free room temperature control via the ceiling surface. The climate ceiling system also contributes to sound absorption in the room.

With the A11 activation, copper pipe and aluminium heat-conducting rails are joined using laser welding technology. The registers are permanently bonded to the metal panels with a special adhesive under high pressure. This enables good heat transfer between the activation and the ceiling panel.

The bonding technology also allows aluminium panels to be activated. Depending on the design, higher thermal capacities can therefore be achieved.

For areas with higher acoustic requirements, additional insulation strips can be inserted. Full-surface insulation can also be provided. The respective design is configured according to the thermal and acoustic requirements of the project.

Basis for assessment

Cooling capacity

The cooling capacity corresponds to the amount of energy per second removed from the room via heat radiation and convection. It is determined in accredited climate laboratories in accordance with SN EN 14240.

For comparison: the heat emitted by a person in an office via radiation and convection is approx. 70 – 80 W; the heat emitted by a laptop is approx. 20 – 50 W.

Heating capacity

The heating capacity corresponds to the energy per second added to the room via heat radiation and convection. It is determined in accredited climate laboratories in accordance with SN EN 14037.

For comparison: The heat output of a person in an office via radiation and convection is approx. 70 – 80 W, whilst that of a laptop is approx. 20 – 50 W.

Sound absorption

As the largest unobstructed surface in a room, the ceiling is particularly well suited to sound absorption. The sound absorption class is determined in accordance with EN ISO 11654, based on measurements carried out in accordance with EN ISO 354 in accredited laboratories.

It serves as a parameter for acoustic designers to calculate the effect of a product on a room’s reverberation time.

Carbon footprint

The carbon footprint describes the greenhouse gas emissions associated with a product. These emissions are expressed as CO₂ equivalents. The life cycle stages considered are specified in the respective Environmental Product Declaration and its defined system boundaries.

An Environmental Product Declaration (EPD) transparently presents various environmental impacts of a product based on a life cycle assessment. The calculation is carried out in accordance with the standards and methodological requirements specified in the EPD. Where stated, the EPD is verified by an independent third party.
