Innogration GmbH is innovatively applying BASF’s Basotect® melamine resin foam as sound insulation in their new Ceiltec® thermo-active prefabricated concrete ceilings.
Thermo-active technology produces extremely energy-efficient cooling and heating in modern buildings, which in some cases can make them eligible for passive house certification. When a thermo-active element is incorporated into a concrete ceiling, this is offset by part of the building to regulate heat.
However, the drawback is typically that the sound-reflecting surfaces of a concrete ceiling mean poorer room acoustics due to longer reverberation times. And fitting acoustic absorbers for sound insulation is not ideal, since they often have an adverse effect on the convection of air needed, which then considerably reduces the efficiency of the cooling and heating capacity.
A holistic solution
To counter this challenge, BASF’s Basotect® sound-insulating melamine resin foam is integrated in the recesses of the Ceiltec® prefabricated ceilings and gives the thermo-active concrete ceiling outstanding multi-functionality with excellent acoustic properties.
Even a small coverage of the ceiling, 10% to 15%, produces a significant reduction in the reverberation time in the room.
Basotect® is a very versatile foam and its high sound absorption capacity not only creates a pleasant acoustic experience, but because it is non-flammable, it is also an important material for fire protection in modern buildings. In addition, since it has an extremely low density and does not contain mineral fibre, Basotect® is very easy to install in the recesses in concrete ceilings.
“The demand for multifunctional structural elements providing both a good indoor climate and improved room acoustics is steadily growing,” says Thomas Friedrich, chief executive officer of Innogration GmbH.
“The integrated Basotect® strip absorbers in the prefabricated Ceiltec® ceiling mean that the system offers a holistic solution – heating and cooling with the concrete surface, but also effective sound absorption on the otherwise sound-reflecting underside of the ceiling.”
Innogration GmbH has already fitted a number of office and administration buildings in Austria, Germany and Switzerland with Ceiltec® concrete prefabricated ceilings, including the Smarthouse in Munich, the Kreativpark office building in Karlsruhe and the Institut Heidger in Osann-Monzel an der Mosel.
“Innogration GmbH’s Ceiltec® thermo-active prefabricated concrete ceilings fitted with Basotect® embody a new trend in the modern office environment and are an example of how the high requirements on energy efficiency, acoustics and design can be met,” Dr Normen Langner from Bilfinger Bauperformance GmbH commented at a joint workshop with BASF last year, titled “Cooling, heating and acoustics in the modern office world”.
