Why the omission of All those comparisons on this page? The full thing about slivers during the arms with mineral fiber, especially Rockwool? Never ever an issue from my encounter, and you should be putting on a mask whether putting in fiberglass or mineral wool in almost any scenario.
Am I location myself fo probable mold problem? I will be speaking with Roxwool science Section tomorrow, will see whatever they say about it .
Fred, although I haven't made use of mineral wool in this application myself, as I like interior foam After i should do basements, I did investigation the topic for a Fine Homebuilding write-up (), and I realize Individuals who have made use of the solution. Anecdotally, insects are fewer drawn to mineral wool than to non-addressed foam, but quite possibly the most pest-resistant product would be foam addressed with an insecticide. (In this particular course, I choose borate-treated EPS; borate is just not toxic to human beings along with the blowing brokers in EPS are considerably less awful than People in XPS.
Within the Winter season, your interior relative humidity must be small and Using the MemBrain close to the interior, it may also be dry. So it's going to Allow very little vapor move from the interior for the concrete.
However, we needed Answer which was easier, cheaper, and would keep away from the need to notch the insulation boards across the fiberglass clips.
We then put in the bracket and steel shelf at the main-ground rim joist. This permitted us to start out putting in the rock wool boards by stacking them about the shelf, overlapping seams, and fastening the batten strips as we went up. The 2 ft.
Chris Gleba contacted my organization, Verdeco Patterns, as our organization were pre-capable by the DER program as designers and builders with tested encounter on higher-performance projects.
If rock wool is denser than fiberglass bats it will eventually attenuate a different choice of frequencies. The tiny top secret of tailor made audio installations is that The everyday stud and fiberglass wall essentially resonates at one hundred HZ; Consequently describing why so many units have muddy bass.
We to start with regarded as making use of rock wool batts, as they typically have the very same thermal price for every inch as the denser board goods, although getting less costly and a lot more readily available.
That's solidly in the middle of Class-III vapor retardency, comparable to that of standard inside latex paint. The housewrap also could well be offering no less than some quantity of capillary crack to limit the level of wicking of ground moisture in the fiber.
I not too long ago offered the fixer higher I bought thirty odd yrs in the past. I gutted it and redid almost everything other than the composition, and was happy with The work I did to the insulation,(fibreglass). When a bit in the wall was exposed I had been horrified to see the mess the mice and squirrels made.
The one position you would Commonly place such a coating will be the place wires or pipes penetrate a fireplace wall. If you would like Manage pipe sweating, use pipe insulation. There are spray-on pipe insulations, and also spray-on fireplace retardent elements (all of which, in my experience, are messy to operate with both equally now and endlessly).
I don't see any issue with painting the batts, just use a sprayer and several low cost latex paint. Every one of the paint will be executing is performing like a sort of binder. I have not genuinely had any concern with mineral wool shedding fibers even though -- it should be good if it isn't disturbed.
So now I'm considering significantly about equally the “breathable household wrap” and “good vapor retarder” references you lifted. I'm attaching several sketches and photographs that can help suggest read more the issue regions I want to handle:
