In this distinctive Today’s Home owner Podcast, we’re conversing all about stone wool insulation with Dan Edelman, Rockwool’s Countrywide Business Progress Manager.


Stone wool insulation is fireplace-resistant and non-combustible, giving your loved ones much more time to safely escape a dwelling hearth. (ROCKWOOL)

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 (abundant in the earth), and slag is a by-product of the metal and copper marketplace. The minerals are melted and spun into fibers.

ROCKWOOL products have among 16% or 40% pre-client recycled materials dependent on the ROCKWOOL manufacturing facility area.

The sum of recycled content material is optimized to give the best thermal, acoustic, and fire safety attributes from ROCKWOOL solutions, although nonetheless maximizing the recycled written content.


ROCKWOOL’s Background

Dan: ROCKWOOL organization began in 1937 in Copenhagen, Denmark, and the enterprise expanded to the North American industry in 1988.

So, our merchandise is somewhat new to North The usa, but historically it is been about for pretty some time now. We just opened up a new superior manufacturing unit in Ranson, West Virginia. 

All of our factories are zero waste-to-landfill, and due to the fact stone wool insulation is hydrophobic, we use recycled rainwater to cut it. Even our factories that are wind- and drinking water-run are self-producing.

You can obtain out additional about how our sustainable factories do the job on ROCKWOOL’s Sustainability webpage.


Strengths of Stone Wool Insulation

Not only is Rockwool insulation very fireplace-resistant, it also is effective to have fireplace and reduce its spread. (Rockwool)

Dan: ROCKWOOL stone wool insulation is naturally fireplace-resistant mainly because it’s manufactured from rock. We really don’t have to add any hearth retardants or substances that enhance flammability, so it’s under no circumstances going to carry a flame and has zero smoke development.

Yet another advantage is mold resistance. ROCKWOOL stone wool insulation essentially repels h2o. There will often be humidity in the air, especially when you’re conversing about crawlspaces and attics.

Staying in a position to repel that dampness absent and forever becoming a mould and mildew-resistant solution, it’s likely to support with the durability of your wall assembly as properly.


Attic Insulation

Dan: ROCKWOOL insulation batts arrive in 16-inch on center or 24-inch on centre by 47 or 48 inches extended, which is the perfect size for insulating attics. They healthy beautifully in between the studs, so you get that entire cavity insulation.

Stage one particular when setting up attic insulation is to examine the present-day insulation. Make guaranteed there’s no moisture, mould mildew, rodent droppings or rodents living there. Rodents never largely treatment for ROCKWOOL insulation. 

Right after inspection, merely lay the batts down perpendicular to the joists, particularly if the current insulation is only to the joists.

If the current insulation is beneath the joists, you’ll want to fill up to the joist line so you get more ongoing insulation.

ROCKWOOL insulation normally has a 4.2 to 4.3 per inch R-benefit, so you essentially never need really as substantially to strike the increased R-value. Even so, we have merchandise with a increased R-worth primarily for attics.

What About Seem Insulation?

Dan: The ideal detail for audio insulation is density and mass, both of which ROCKWOOL has. 

The other portion to sound insulation is friction suit, how restricted it fits in that wall cavity. If you have a single spot that you can not insulate thoroughly, all the seem is going by means of that one area and you are lessening that seem insulation.
