Author Topic: Metal roll shutters with polyfoam insulation do anything for low frequency sound  (Read 323 times)

Hi

Do metal roll shutters with polyfoam insulation  do anything to attenuate low frequency sounds like trucks, bass, buses, etc?

It would add some mass but I read in the forums the metal shutters do very little for sound.

Online most sites tout sound blocking ability but an australian site states it does little for low frequency.


Thoughts?


Thanks

No they are not going to achieve the value in low frequency, you need mass, large air gap 3"+ and more mass.
