“Soundproofing is so important”
"I always tell homeowners that soundproofing is difficult and expensive to get even modest results."
John Bleasby recently posted an article called “Before the Drywall is Installed” that discussed ten things contractors could do between the studs, but often don’t. Number 10 on his list was soundproofing.
Here is a comment about that from Rob….
“Good list, #10 is so important. My only objection would be insulating with Roxul for soundproofing. I’ve found that it doesn’t make any difference to travelling noise. The NRC has published many great papers on sound transmission through assemblies. You would be better off to put up 5/8″ Type X and seal any electrical penetrations with acoustic putty. I always tell homeowners that soundproofing is difficult and expensive to get even modest results. In the end, we usually install Roxul and 1/2″ DW at their request. Sorry for the tangent.”
