I such as the plastic cable staples that have a nail on either close -- It really is really hard to harm the cable when installing Those people sort, and you can put in them that has a smaller hammer that's much easier to do the job with in restricted Areas.
Conversely just the R15 within a 2x4 wall currently fulfills or exceeds IRC code min for zone three, even though derating the rock batts for not having an exterior aspect air barrier.
Overall, mineral wool is an excellent developing materials with great effectiveness steps nonetheless it incorporates a major producing influence.
There are some driving components for me in searching into this. I like the fireplace resistance of your Rockwool. Rockwool is on the market at the massive box retailers. The foam board available that I’ve observed has questionable scores on ground Speak to and termite resistance.
We envisioned a simple set up with wood furring strips holding the rock wool insulation straight over the Tyvek Professional Wrap, our decided on WRB. The Tyvek would adequately serve as our air barrier and WRB, and it experienced the large permeance that we preferred for your “vapor-out” assembly.
We used the conventional 24-inch huge industrial acoustic rock wool batts for this vented roof application, and the batts in good shape snugly inside our TJI framing set at 24 inches on center.
In a fully enclosed wall cavity, the main difference in the seem attenuation in between mineral wool and large density fiberglass batts is just not recognizable.

This seems like it would reduce the publicity of froth to bugs when you’ve performed a superb work encapsulating. [Particular question: does the insulation really need to go onto the crawlspace wall here initial, prior to the vapor barrier? I know some encapsulation providers do that, but on poured walls. They then only go about six” up and tape the vapor barrier to the rigid foam.]
Even so, “a change far from the dominating utilization of coke to your greener supply of Power for thermal energy while in the creation of mineral wool could change the effects of this review totally, allowing for for increased amounts of insulation even though preserving local climate transform impact gain.”
Rock wool on the other hand will wick humidity towards the moisture & mold-susceptible end interior. The rock wool must dry towards the interior, the foundation does not. So putting a drain aircraft content which is also vapor retarder between the concrete/CMU as well as dampness-wicking fiber isn't going to damage, and could even be needed if there is A great deal ground humidity which makes it into the muse wall.
I agree in part, but I am not sure It is really that easy. FIrst, Even though you concur with the primary difference in functionality Fernando has cited, the benefit of mineral wool won't translate into anything at all in the vicinity of that amount of enhancement in The entire wall or roof R-values.
While we located samples of related installations in Europe, our developing science consultants (Cathy Gates and Ken Neuhauser) ended up concerned that wind-washing from the significantly less-dense batts would degrade the thermal effectiveness in the insulation.
Rockwool does not head water and will not get eaten. I don't Assume anything at all will even nest in the rigid Model of rock wool, but may within the softer rock wool batts. Overall guess in this article, making use of rigid foam which includes an authorised fireplace ranking could be a less difficult job.
