I visualize the more recent bigger density fiberglass is much less problematic in this way.

Discourage possibly, but rock wool won't halt rodents. I have identified nests in remaining over batts I had piled up in a crawlspace.

In spite of price tag (not A lot of difference below in Upstate NY for related R-values), and all of the reasons expressed by Robert F. in favor of mineral wool, There's a person critical aspect not one person has pointed out. The seem deadening element mineral wool provides towards the desk wins hands down in excess of fiberglass. We are builders who are living in a zero Strength home for 6 decades that was insulated with Rockwool; R15 x 3 from the walls.

You may get blown mineral wool insulation. I’ve under no circumstances made use of, or maybe viewed, the stuff, nevertheless it’s available. In case you don’t choose to use cellulose (which is usually the preferred option for blown in insulation in an attic), you’d almost certainly be ideal off working with blown mineral wool instead of batts. Blown insulation is actually very best for an attic floor, and it’s definitely the easiest to use.

This helps make Harmless'n'sound somewhat shy of R13 in terms of thermal functionality.

Are there unique goods boasting R-five/in? The rigid mineral wool items I'm aware of are around R-4.2/in. Rockwool's sustainability logic is flawed; employing any sort of insulation will offset its carbon emissions ultimately, when compared with not applying any insulation whatsoever.

The explanation is that even though mineral wool has a slight edge in excess of fiberglass in acoustic transfer in a head-to-head comparison, the instant you install possibly right into a wall, it turns into the least significant Component of that assembly Which slight edge is erased.

I'm glad the Heco Topix Therm worked on this task. I remember that the mineral wool thickness was proper at the sting of your operating assortment wherever it wouldn't compress the MW. It would not seem like you had a lot of issues.

Hi Fred, Sorry for hold off in response.... As both equally Martin and Michael commented, you'll find mineral wool panels designed for underneath quality problems and so long as the perimeter soil is perfectly-draining, this beneath quality mineral wool could be a superior substitute to foam products. Even so, the project highlighted in this article was a deep Strength retrofit of the existing construction and whole excavation exposing the outside foundation would have been needed to put in insulation on the outside aspect of the inspiration - not a realistic thought on this restricted urban web site.
