Stone wool insulation is fire-resistant and non-combustible, offering your family extra time to safely escape a house fire. (ROCKWOOL)

What is ROCKWOOL insulation?

Dan: ROCKWOOL insulation is a rock-centered mineral fiber insulation comprised of Basalt rock and Recycled Slag. Basalt is a volcanic rock (plentiful in the earth), and slag is a by-product or service of the metal and copper industry. The minerals are melted and spun into fibers.

ROCKWOOL solutions contain between 16% or 40% pre-shopper recycled substance dependent on the ROCKWOOL producing facility area.

The amount of money of recycled content is optimized to deliver the excellent thermal, acoustic, and fire security homes from ROCKWOOL merchandise, whilst even now maximizing the recycled information.


ROCKWOOL’s Background

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

So, our product is somewhat new to North The us, but historically it is been about for very some time now. We just opened up a new superior manufacturing facility in Ranson, West Virginia. 

All of our factories are zero squander-to-landfill, and simply because stone wool insulation is hydrophobic, we use recycled rainwater to slice it. Even our factories that are wind- and water-driven are self-making.

You can obtain out a lot more about how our sustainable factories work on ROCKWOOL’s Sustainability webpage.


Pros of Stone Wool Insulation

Not only is Rockwool insulation very fireplace-resistant, it also performs to include fireplace and protect against its unfold. (Rockwool)

Dan: ROCKWOOL stone wool insulation is normally fire-resistant simply because it is produced from rock. We don’t have to increase any hearth retardants or chemical compounds that raise flammability, so it is by no means heading to carry a flame and has zero smoke progress.

A different gain is mould resistance. ROCKWOOL stone wool insulation basically repels h2o. There will always be dampness in the air, specifically when you’re speaking about crawlspaces and attics.

Remaining able to repel that humidity away and without end getting a mould and mildew-resistant product or service, it’s likely to enable with the durability of your wall assembly as properly.


Attic Insulation

Dan: ROCKWOOL insulation batts occur in 16-inch on middle or 24-inch on center by 47 or 48 inches extended, which is the excellent measurement for insulating attics. They fit properly concerning the studs, so you get that full cavity insulation.

Action 1 when installing attic insulation is to examine the present insulation. Make sure there is no moisture, mould mildew, rodent droppings or rodents dwelling there. Rodents don’t generally treatment for ROCKWOOL insulation. 

After inspection, simply just lay the batts down perpendicular to the joists, primarily if the present insulation is only to the joists.

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

ROCKWOOL insulation usually has a 4.2 to 4.3 per inch R-price, so you really don’t need quite as substantially to strike the larger R-worth. Having said that, we have solutions with a higher R-benefit principally for attics.

What About Sound Insulation?

Dan: The best factor for audio insulation is density and mass, both of those of which ROCKWOOL has. 

The other portion to sound insulation is friction in good shape, how tight it suits in that wall cavity. If you have just one location that you can’t insulate correctly, all the sound is heading by means of that just one section and you are lessening that audio insulation.
