VARICOOL AP

Radiant ceiling jointless

The jointless VARICOOL AP radiant heating and cooling ceiling is suitable for projects where thermal comfort is to be combined with a seamless ceiling appearance. Visually, it corresponds to a conventional drywall ceiling. Full-surface ceiling activation, flexible arrangement of the activation profiles, integrated components and individual ceiling designs with 3D elements are possible. VARICOOL AP can also be designed as a ceiling sail.

For higher acoustic requirements, perforated plasterboard panels with acoustic fleece applied to the rear can be used. Depending on the requirements, an insulation layer can be provided for additional sound absorption.

The activation profiles for jointless radiant heating and cooling ceilings are adapted to the standard substructure and replace parts of it. The system is suitable for use with gypsum, expanded-glass granulate and aluminium honeycomb panels.

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 are expressed in CO₂ equivalents.

For this product, the information is based on life cycle calculations carried out using internal procedures. The life cycle stages covered, system boundaries and calculation basis are specified in the accompanying documentation.
