The acoustical performance of a curtain wall is defined by
The performance of its infill elements; and
The performance of the profiles of the curtain wall system
As the Fassada H60 hybrid system
has no external pressure plate and no screws (knowing that each screw holding the pressure plate is a noise bridge);
has a thick and heavy exterior shell for static reasons, which is also favourable for the acoustic performance (the famous mass law):
it is obvious, on condition of the same infill elements of course, that it will be always more performant than any conventional facade.
