In this unique Today’s Homeowner Podcast, we’re chatting all about stone wool insulation with Dan Edelman, Rockwool’s Countrywide Small business Growth Supervisor.

Stone wool insulation is fireplace-resistant and non-combustible, offering your loved ones a lot more time to properly escape a property fire. (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 (ample in the earth), and slag is a by-item of the metal and copper sector. The minerals are melted and spun into fibers.

ROCKWOOL solutions consist of among 16% or 40% pre-consumer recycled material dependent on the ROCKWOOL producing facility locale.

The quantity of recycled content material is optimized to present the perfect thermal, acoustic, and hearth safety houses from ROCKWOOL products and solutions, although nevertheless maximizing the recycled material.

Dan: ROCKWOOL organization began in 1937 in Copenhagen, Denmark, and the business expanded to the North American current market in 1988.

So, our product or service is somewhat new to North The united states, but historically it’s been around for pretty some time now. We just opened up a new state-of-the-art factory 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 minimize it. Even our factories that are wind- and drinking water-powered are self-producing.

You can find out a lot more about how our sustainable factories get the job done on ROCKWOOL’s Sustainability webpage.

Benefits of Stone Wool Insulation

Not only is Rockwool insulation particularly fireplace-resistant, it also works to consist of fireplace and protect against its spread. (Rockwool)

Dan: ROCKWOOL stone wool insulation is normally fire-resistant due to the fact it is designed from rock. We do not have to add any fireplace retardants or chemical compounds that enhance flammability, so it’s by no means likely to carry a flame and has zero smoke improvement.

Yet another benefit is mould resistance. ROCKWOOL stone wool insulation basically repels drinking water. There will generally be dampness in the air, specifically when you are talking about crawlspaces and attics.

Remaining in a position to repel that moisture away and without end getting a mould and mildew-resistant item, it’s going to assist with the longevity of your wall assembly as properly.

Attic Insulation

Dan: ROCKWOOL insulation batts appear in 16-inch on middle or 24-inch on heart by 47 or 48 inches prolonged, which is the excellent sizing for insulating attics. They in good shape beautifully amongst the studs, so you get that entire cavity insulation.

Move one particular when installing attic insulation is to examine the present-day insulation. Make confident there’s no moisture, mildew mildew, rodent droppings or rodents residing there. Rodents do not largely treatment for ROCKWOOL insulation. 

After inspection, simply lay the batts down perpendicular to the joists, specially if the existing insulation is only to the joists.

If the present insulation is underneath the joists, you’ll want to fill up to the joist line so you get much more constant insulation.

ROCKWOOL insulation commonly has a 4.2 to 4.3 for each inch R-value, so you essentially really do not want rather as considerably to strike the higher R-price. Nonetheless, we have products with a larger R-worth generally for attics.

What About Sound Insulation?

Dan: The very best matter for audio insulation is density and mass, each of which ROCKWOOL has. 

The other aspect to audio insulation is friction fit, how restricted it suits in that wall cavity. If you have one area that you just can’t insulate correctly, all the seem is going via that a person portion and you’re minimizing that sound insulation.
