In this specific Today’s Homeowner Podcast, we’re chatting all about stone wool insulation with Dan Edelman, Rockwool’s Nationwide Business Progress Manager.
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 (ample in the earth), and slag is a by-merchandise of the steel and copper marketplace. The minerals are melted and spun into fibers.
ROCKWOOL goods contain in between 16% or 40% pre-customer recycled content dependent on the ROCKWOOL production facility site.
The amount of recycled content material is optimized to deliver the suitable thermal, acoustic, and fireplace defense attributes from ROCKWOOL items, while nonetheless maximizing the recycled material.
ROCKWOOL’s Record
Dan: ROCKWOOL organization started in 1937 in Copenhagen, Denmark, and the company expanded to the North American market in 1988.
So, our item is rather new to North The united states, but historically it’s been all-around for pretty some time now. We just opened up a new state-of-the-art manufacturing facility 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 reduce it. Even our factories that are wind- and h2o-powered are self-making.
You can find out a lot more about how our sustainable factories get the job done on ROCKWOOL’s Sustainability webpage.
Advantages of Stone Wool Insulation
Dan: ROCKWOOL stone wool insulation is the natural way hearth-resistant since it is produced from rock. We really do not have to increase any hearth retardants or chemicals that improve flammability, so it’s under no circumstances likely to carry a flame and has zero smoke development.
A further advantage is mildew resistance. ROCKWOOL stone wool insulation in fact repels h2o. There will usually be dampness in the air, in particular when you are chatting about crawlspaces and attics.
Being ready to repel that dampness away and permanently becoming a mould and mildew-resistant product, it’s heading to assistance with the toughness of your wall assembly as perfectly.
Attic Insulation
Dan: ROCKWOOL insulation batts appear in 16-inch on centre or 24-inch on center by 47 or 48 inches extended, which is the excellent measurement for insulating attics. They match flawlessly amongst the studs, so you get that total cavity insulation.
Action a single when installing attic insulation is to examine the current insulation. Make guaranteed there’s no moisture, mould mildew, rodent droppings or rodents residing there. Rodents do not mainly treatment for ROCKWOOL insulation.
Immediately after inspection, basically lay the batts down perpendicular to the joists, specially if the current insulation is only to the joists.
If the present insulation is underneath the joists, you will want to fill up to the joist line so you get extra continual insulation.
ROCKWOOL insulation generally has a 4.2 to 4.3 per inch R-benefit, so you basically really do not have to have fairly as considerably to hit the larger R-value. Nevertheless, we have products and solutions with a greater R-worth primarily for attics.
What About Audio Insulation?
Dan: The very best point for seem insulation is density and mass, both of which ROCKWOOL has.
The other element to sound insulation is friction in shape, how limited it suits in that wall cavity. If you have one particular area that you simply cannot insulate thoroughly, all the audio is going by means of that a person area and you are reducing that seem insulation.
