So, our solution is comparatively new to North The united states, but traditionally it is been close to for fairly some time now. We just opened up a new sophisticated manufacturing unit in Ranson, West Virginia. 

All of our factories are zero waste-to-landfill, and simply because stone wool insulation is hydrophobic, we use recycled rainwater to lower it. Even our factories that are wind- and water-run are self-creating.

Pros of Stone Wool Insulation

Not only is Rockwool insulation exceptionally hearth-resistant, it also will work to consist of fire and avert its spread. (Rockwool)

Dan: ROCKWOOL stone wool insulation is the natural way hearth-resistant for the reason that it is designed from rock. We don’t have to incorporate any hearth retardants or substances that maximize flammability, so it is never going to have a flame and has zero smoke advancement.

Dan: ROCKWOOL insulation batts come in 16-inch on center or 24-inch on heart by 47 or 48 inches long, which is the ideal dimensions for insulating attics. They suit beautifully between the studs, so you get that comprehensive cavity insulation.

Action a person when installing attic insulation is to inspect the present-day insulation. Make guaranteed there is no humidity, mould mildew, rodent droppings or rodents living there. Rodents do not principally treatment for ROCKWOOL insulation. 

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

If the current insulation is down below the joists, you are going to want to fill up to the joist line so you get a lot more steady insulation.

ROCKWOOL insulation generally has a 4.2 to 4.3 for every inch R-price, so you actually do not need to have rather as considerably to hit the better R-benefit. On the other hand, we have items with a bigger R-worth mostly for attics.
