In this unique Today’s Homeowner Podcast, we’re chatting all about stone wool insulation with Dan Edelman, Rockwool’s National Enterprise Enhancement Supervisor.
What is ROCKWOOL insulation?
Dan: ROCKWOOL insulation is a rock-primarily based mineral fiber insulation comprised of Basalt rock and Recycled Slag. Basalt is a volcanic rock (plentiful in the earth), and slag is a by-solution of the metal and copper sector. The minerals are melted and spun into fibers.
ROCKWOOL solutions incorporate involving 16% or 40% pre-shopper recycled content dependent on the ROCKWOOL manufacturing facility site.
The sum of recycled written content is optimized to deliver the perfect thermal, acoustic, and hearth defense qualities from ROCKWOOL goods, although nonetheless maximizing the recycled content.
ROCKWOOL’s Historical past
Dan: ROCKWOOL company began in 1937 in Copenhagen, Denmark, and the firm expanded to the North American industry in 1988.
So, our merchandise is relatively new to North America, but traditionally it’s been around for really some time now. We just opened up a new superior manufacturing facility in Ranson, West Virginia.
All of our factories are zero waste-to-landfill, and since stone wool insulation is hydrophobic, we use recycled rainwater to slash it. Even our factories that are wind- and drinking water-driven are self-making.
You can locate out extra about how our sustainable factories get the job done on ROCKWOOL’s Sustainability webpage.
Positive aspects of Stone Wool Insulation
Dan: ROCKWOOL stone wool insulation is the natural way fire-resistant because it is designed from rock. We do not have to incorporate any hearth retardants or chemicals that increase flammability, so it’s under no circumstances likely to have a flame and has zero smoke advancement.
A different advantage is mould resistance. ROCKWOOL stone wool insulation basically repels h2o. There will usually be humidity in the air, specifically when you are speaking about crawlspaces and attics.
Becoming in a position to repel that moisture away and permanently being a mold and mildew-resistant product, it’s heading to enable with the toughness of your wall assembly as nicely.
Dan: ROCKWOOL insulation batts come in 16-inch on centre or 24-inch on heart by 47 or 48 inches long, which is the excellent sizing for insulating attics. They healthy properly involving the studs, so you get that whole cavity insulation.
Stage a person when installing attic insulation is to examine the existing insulation. Make certain there’s no humidity, mould mildew, rodent droppings or rodents dwelling there. Rodents don’t generally care for ROCKWOOL insulation.
Immediately after inspection, simply just lay the batts down perpendicular to the joists, especially if the current insulation is only to the joists.
If the present insulation is underneath the joists, you are going to want to fill up to the joist line so you get far more ongoing insulation.
ROCKWOOL insulation typically has a 4.2 to 4.3 for every inch R-worth, so you basically never want quite as substantially to strike the increased R-price. Having said that, we have items with a greater R-benefit mostly for attics.
What About Sound Insulation?
Dan: The finest issue for audio insulation is density and mass, equally of which ROCKWOOL has.
The other component to seem insulation is friction suit, how restricted it suits in that wall cavity. If you have 1 location that you can’t insulate correctly, all the audio is heading through that one particular part and you’re lessening that seem insulation.
