A11-S

Radiant metal ceiling sail

The A11-S radiant ceiling sail is a climate ceiling system with room air flowing around it. It offers very high heating and cooling capacity. If full-surface insulation is omitted, the rear side of the sail can also contribute to heat transfer and thereby support cooling capacity.

The A11 activation is based on a specially developed construction. Copper pipe and aluminium heat-conducting rails are welded together using laser technology. The registers are bonded to the metal panels with a special adhesive under high pressure. This construction supports good heat transfer between the register and the ceiling panel. The bonding technology also allows aluminium panels to be activated, which can provide higher thermal capacity depending on the design.

Optional capacity boost: A11-S + Convector Wings

Capacity can be increased by using the Convector Wings developed and patented by Barcol-Air. These are matt-black anodised aluminium profiles with slotted wings raised on both sides. The profiles are clipped onto the straight sections of the pipe meander. This increases the heat-transfer surface and raises the thermal capacity.

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.
