I do not know but attic installations just expected laying the batts down so I don't think the latter experienced just about anything to complete with it. I envision the more recent larger density fiberglass is much less problematic in this way.

As The controversy to the environmental effects of spray and rigid foam insulation proceeds, a lot of designers, builders, and homeowners may well prefer to Allow buildings “breathe” as an alternative to wrap them in foam.
In a completely enclosed wall cavity, the primary difference within the audio attenuation concerning mineral wool and superior density fiberglass batts is not visible.
If rock wool is denser than fiberglass bats it will eventually attenuate another number of frequencies. The tiny key of customized audio installations is that The everyday stud and fiberglass wall really resonates at a hundred HZ; Consequently detailing why a lot of devices have muddy bass.
In recent times, I’ve listened to about the usage of exterior rock wool insulation, As well as in my First conversation with Chris, I was delighted to hear that he was thinking about working with the item.

Do they make rigid foam with a decent hearth rating? I’ve not seen that and would reduce one among my even larger issues.
RE audio attenuation, Johns Manville manufactures fiberglass and rock wool batts -- and states "...the real difference in acoustical overall performance is so nominal that human beings wouldn't have the opportunity to tell apart a distinction between The 2 supplies in a wall cavity." See: Be aware, nonetheless, that JM didn't specify regardless of whether dense or regular fiberglass batts ended up utilised In this particular comparison, and seem reduction is considerably more complicated than simply which sort of batt you use inside of a wall.
