In this distinctive Today’s Home-owner Podcast, we’re chatting all about stone wool insulation with Dan Edelman, Rockwool’s Nationwide Business enterprise Enhancement Manager.
What is ROCKWOOL insulation?
Dan: ROCKWOOL insulation is a rock-based mineral fiber insulation comprised of Basalt rock and Recycled Slag. Basalt is a volcanic rock (ample in the earth), and slag is a by-solution of the steel and copper field. The minerals are melted and spun into fibers.
ROCKWOOL products and solutions have in between 16% or 40% pre-shopper recycled product dependent on the ROCKWOOL production facility place.
The total of recycled content material is optimized to present the excellent thermal, acoustic, and fireplace safety homes from ROCKWOOL merchandise, though nevertheless maximizing the recycled content.
Dan: ROCKWOOL business commenced in 1937 in Copenhagen, Denmark, and the organization expanded to the North American industry in 1988.
So, our products is reasonably new to North The us, but historically it is been all around for really some time now. We just opened up a new sophisticated manufacturing facility in Ranson, West Virginia.
All of our factories are zero squander-to-landfill, and for the reason that stone wool insulation is hydrophobic, we use recycled rainwater to slash it. Even our factories that are wind- and h2o-powered are self-producing.
You can discover out additional about how our sustainable factories do the job on ROCKWOOL’s Sustainability webpage.
Pros of Stone Wool Insulation
Dan: ROCKWOOL stone wool insulation is naturally fireplace-resistant for the reason that it’s manufactured from rock. We don’t have to include any fire retardants or chemical substances that improve flammability, so it’s under no circumstances likely to have a flame and has zero smoke enhancement.
An additional benefit is mildew resistance. ROCKWOOL stone wool insulation really repels drinking water. There will normally be humidity in the air, particularly when you’re speaking about crawlspaces and attics.
Currently being able to repel that humidity away and for good being a mold and mildew-resistant merchandise, it’s likely to enable with the toughness of your wall assembly as nicely.
Dan: ROCKWOOL insulation batts appear in 16-inch on center or 24-inch on center by 47 or 48 inches very long, which is the fantastic size for insulating attics. They suit completely in between the studs, so you get that total cavity insulation.
Move one when putting in attic insulation is to inspect the latest insulation. Make certain there is no dampness, mould mildew, rodent droppings or rodents living there. Rodents really don’t mostly care for ROCKWOOL insulation.
Following inspection, merely lay the batts down perpendicular to the joists, specially if the current insulation is only to the joists.
If the current insulation is under the joists, you will want to fill up to the joist line so you get more continuous insulation.
ROCKWOOL insulation normally has a 4.2 to 4.3 for each inch R-value, so you actually do not want pretty as substantially to strike the higher R-value. Even so, we have solutions with a increased R-worth principally for attics.
What About Audio Insulation?
Dan: The ideal detail for seem insulation is density and mass, both equally of which ROCKWOOL has.
The other portion to audio insulation is friction suit, how tight it fits in that wall cavity. If you have a single place that you just can’t insulate effectively, all the audio is going via that a person section and you’re lowering that seem insulation.
