The sound-absorbing façade

THE ACOUSTIC PROTECTION FAÇADE

In urban areas, the issue of sound insulation is becoming increasingly important due to noise pollution. With an in-built sound-insulating component, the FC façade system from Kalzip offers a sensible solution to noise pollution.

The façade protects buildings from various weather influences and, in the case of modern energy-efficient buildings, also from heat loss. As a further functional task, the external wall can also have a considerable influence on the volume of external noise. The FC façade system from Kalzip has now been further developed to combine sound-absorbing properties and design flexibility. The structure is very simple: designed as a simple rear-ventilated curtain wall, sound-absorbing thermal insulation is installed between the substructure and the perforated aluminium panels to limit sound transmission. With 3 or 6 millimetre perforations in the panels, some of the sound can pass through the panels. There it hits the thermal insulation and is absorbed by it.

VERIFIABLE VALUES

“The sound insulation and absorption measures of the FC façade absorb up to 6 decibels of sound,” reports Ronald Wloka, Sales Manager FC Façade at Kalzip. “This improves the indoor climate inside the building and has a corresponding effect on the working and living atmosphere. At the same time, sounds and noise are not reflected to the outside. This automatically makes the urban environment quieter.” In co-operation with the Fraunhofer Institute in Stuttgart, a system structure was designed on the basis of DIN 4109-1 “Requirements for the sound insulation of building components in rooms requiring protection”, which ensures the high requirements for sound insulation in mixed-use areas. Interested in a solution that combines a metal façade with sound insulation, MPLUS Architekten supported the series of tests. The FC façade has been proven to offer a solution for optimising sound insulation in and on buildings and thus contributing to improving the quality of life.
