Then we get on the NRC rating. That score is focused on absorption, so I see it primarily inside the context of acoustic control as opposed to seem attenuation/blocking. It really is, certainly, popular to use mineral wool batts to make affordable acoustic Handle panels.

Mark, Thank you for the reply and responses. Did you consider using EPS foam in lieu of mineral wool for the above mentioned grade walls? Although less vapor permeable than mineral wool, wouldn't EPS Nonetheless let some drying to the exterior and be lighter and much less expensive than mineral wool whilst giving around exactly the same R-price per inch? barkingeater
Even so, we needed solution that was less complicated, more cost-effective, and would stay away from the necessity to notch the insulation boards round the fiberglass clips.
There is absolutely no vapor barrier/retarder on the bottom aspect in the sub floor. Will setting up the mineral wool insulation after which you can applying a vaper retarder (portray) the insulation be a problem for humidity? We are now living in zone four. The basement walls are insulated.
The designer of the deep Vitality retrofit task in Massachusetts specified 6 inches of mineral wool insulation for the exterior facet of your partitions
In addition to a optimistic relationship to the present wall plates we were capable to eliminate the structural hundreds on the existing two×six roof rafters, which were each structurally undersized and not able to tackle A lot insulation inside of their constrained depth.
This looks as if it would scale back the publicity of foam to bugs in the event you’ve finished a superb job encapsulating. [Specific concern: does the insulation have to go onto the crawlspace wall first, prior to the vapor barrier? I understand some encapsulation corporations do this, but on poured walls. They then only more info go about 6” up and tape the vapor barrier for the rigid foam.]

Rock wool Then again will wick humidity toward the moisture & mould-prone finish inside. The rock wool must dry towards the interior, the foundation does not. So Placing a drain aircraft materials that's also vapor retarder between the concrete/CMU and the dampness-wicking fiber won't hurt, and could even be important if there is Substantially floor moisture which makes it into the muse wall.
If instead you use the primary difference in selling price involving the two types of batts, there could be other areas to invest that cash which might produce greater effects.
On the other hand, In accordance with this Rockwool Sustainability Report, the market claims mineral wool may become “net carbon optimistic” inside of 200 times, “indicating the carbon emitted over the manufacture of constructing insulation is offset through the avoided emissions of the insulation’s use in properties.
Rockwool won't mind drinking water and does not get eaten. I don't think anything will even nest inside the rigid Model of rock wool, but might inside the softer rock wool batts. Overall guess in this article, utilizing rigid foam that has an accepted hearth score would be a much simpler task.
