INSTALLING CEILING COOLING/HEATING SYSTEMS

Panel: The ecologically tested gypsum fibre board consists of recycled paper fibres, gypsum and water (without binding agents). The components are pressed under high pressure to form a stable and odourless board. 

The Variotherm acoustic panels including the integrated modular pipe have been tested by TÜV Rheinland in Nuremberg. Eight different test pieces were set up in a modern echo chamber with a volume of around 400 m³ and a reverberation time of approximately 7 seconds. All standard frequencies were thoroughly tested over a defined period of time.

A test was conducted to determine how much sound could be expected to be absorbed with ModulePanels with the acoustic function once they were installed. The result: The test conducted by the TÜV verifies and guarantees the excellent sound-absorbing effect of the acoustic surface!

On ceilings and roof slopes, the radiant surfaces are not obstructed by furnishings. They are therefore ideally suited for heating and cooling.

Experience shows: The comfort is perceived up to a distance of 3.5 m from the active cooling surface. In higher rooms the ceiling should be suspended because the radiant effect on the body declines in proportion to the square of the distance.

The VarioModule-File pipe uses the advantages of both aluminium and plastic. It combines five interconnected layers. That guarantees a slightly flexible yet dimensionally stable pipe.

The innermost layer is made of polyethylene and temperature resistant. The inner surface is smooth as glass, making it impossible for deposits to form. The water flows through the pipe without resistance and with minimal pressure losses. 

The ModulePanels are screwed onto a substructure made of timber studs or metal profiles. The structure can be constructed with or without surface panelling or cavity insulation and vapour retarders (vapour barrier).

• With wooden constructions, the timber used must be sufficiently dry and straight, and conform to the Austrian standard DIN 4074-1 (quality class 2 and cutting class S = sharp-edged).
• With metal constructions, the profiles must be made of soft, non-alloyed steel with double-sided galvanising of at least 100 g/m² according to the Austrian standard DIN 18 182-1 or DIN EN 14 195.
• The construction has to be designed to carry the weight of the ModulePanels (20.5 kg/m²) and any eventual additional loads (e. g. ceiling lights). Additional loads such as ceiling lights, multi-layer planking and other fittings must also be taken into account!
