Mineral wool retains its shape a lot better than fiberglass or cellulose. It will never settle within partitions, leaving cold gaps along the highest plate. If there’s air infiltration, moisture will not compromise or degrade its thermal effectiveness; and the material provides no food stuff to assist microorganisms.
Nevertheless I'm able to’t visualize organization like roxwool with all their funds and investigation would suggest a thing that would create a challenge. But who is familiar with ?!? I’ll Get in touch with their science Office and report back again listed here .
I've exposed mineral wool batts while in the upper walls of my basement with no concerns so far as I am able to convey to (admittedly I am in Seattle, which won't get significant humidity). Regardless if chopping the stuff I did not detect any obvious shedding of fibers (nevertheless of course It truly is a smart idea to dress in a mask in the course of set up No matter).

My analysis suggests Rockwool insulation appears to have some helpful Homes, like the opportunity to dry out if subjected to moisture. But this exact same investigation has occur up vacant regarding regardless of whether delivering pure ventilation space behind unfaced Rockwool makes it possible for this job to maneuver ahead without a vapor barrier. Whether or not working with faced Rockwool could possibly be a feasible different also stays an unanswered issue.
With most of these constructive traits, we felt committed to utilizing it for this undertaking. Most rock wool board and batt goods common all around R-4.two for each inch, Therefore the challenge then became: How would we Charge-correctly wrap close to 6 inches of rock wool insulation on the exterior of a Wooden construction whilst anticipating some way to connect the siding?
