In this exclusive Today’s Home-owner Podcast, we’re speaking all about stone wool insulation with Dan Edelman, Rockwool’s Nationwide Business Improvement Manager.
What is ROCKWOOL insulation?
Dan: ROCKWOOL insulation is a rock-based mostly mineral fiber insulation comprised of Basalt rock and Recycled Slag. Basalt is a volcanic rock (abundant in the earth), and slag is a by-products of the metal and copper business. The minerals are melted and spun into fibers.
ROCKWOOL merchandise incorporate among 16% or 40% pre-client recycled material dependent on the ROCKWOOL manufacturing facility locale.
The sum of recycled content is optimized to provide the perfect thermal, acoustic, and fireplace protection properties from ROCKWOOL solutions, even though continue to maximizing the recycled information.
ROCKWOOL’s Background
Dan: ROCKWOOL organization began in 1937 in Copenhagen, Denmark, and the company expanded to the North American market in 1988.
So, our merchandise is reasonably new to North America, but historically it’s been all-around for quite some time now. We just opened up a new state-of-the-art manufacturing unit in Ranson, West Virginia.
All of our factories are zero squander-to-landfill, and because stone wool insulation is hydrophobic, we use recycled rainwater to lower it. Even our factories that are wind- and h2o-driven are self-generating.
You can locate out far more about how our sustainable factories operate on ROCKWOOL’s Sustainability webpage.
Benefits of Stone Wool Insulation
Dan: ROCKWOOL stone wool insulation is in a natural way fire-resistant for the reason that it is manufactured from rock. We really do not have to include any fireplace retardants or chemical compounds that maximize flammability, so it is never going to carry a flame and has zero smoke growth.
Another gain is mildew resistance. ROCKWOOL stone wool insulation truly repels h2o. There will often be moisture in the air, particularly when you are chatting about crawlspaces and attics.
Currently being ready to repel that moisture absent and permanently being a mold and mildew-resistant product, it is going to assist with the toughness of your wall assembly as effectively.
Attic Insulation
Dan: ROCKWOOL insulation batts come in 16-inch on center or 24-inch on middle by 47 or 48 inches extended, which is the best dimension for insulating attics. They match perfectly in between the studs, so you get that entire cavity insulation.
Stage a single when putting in attic insulation is to inspect the latest insulation. Make guaranteed there is no humidity, mold mildew, rodent droppings or rodents dwelling there. Rodents don’t primarily care for ROCKWOOL insulation.
Right after inspection, simply just lay the batts down perpendicular to the joists, in particular if the existing insulation is only to the joists.
If the current insulation is below the joists, you will want to fill up to the joist line so you get far more ongoing insulation.
ROCKWOOL insulation normally has a 4.2 to 4.3 for every inch R-worth, so you in fact really do not need rather as a lot to hit the bigger R-value. Having said that, we have products and solutions with a better R-worth primarily for attics.
What About Audio Insulation?
Dan: The finest issue for audio insulation is density and mass, equally of which ROCKWOOL has.
The other section to sound insulation is friction fit, how limited it matches in that wall cavity. If you have a person place that you just cannot insulate adequately, all the sound is going by way of that 1 part and you are reducing that seem insulation.
