Stone wool insulation is fireplace-resistant and non-flamable, giving your spouse and children far more time to properly escape a house fireplace. (ROCKWOOL)

What is ROCKWOOL insulation?

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

ROCKWOOL products comprise amongst 16% or 40% pre-buyer recycled material dependent on the ROCKWOOL manufacturing facility locale.

The amount of recycled written content is optimized to present the perfect thermal, acoustic, and hearth protection houses from ROCKWOOL goods, when continue to maximizing the recycled articles.

ROCKWOOL’s History

Dan: ROCKWOOL company started in 1937 in Copenhagen, Denmark, and the corporation expanded to the North American industry in 1988.

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

All of our factories are zero waste-to-landfill, and since stone wool insulation is hydrophobic, we use recycled rainwater to lower it. Even our factories that are wind- and h2o-powered are self-generating.

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

Rewards of Stone Wool Insulation

Not only is Rockwool insulation really hearth-resistant, it also will work to incorporate hearth and reduce its unfold. (Rockwool)

Dan: ROCKWOOL stone wool insulation is normally fireplace-resistant since it’s produced from rock. We really do not have to incorporate any fireplace retardants or substances that boost flammability, so it’s hardly ever heading to carry a flame and has zero smoke improvement.

Another gain is mould resistance. ROCKWOOL stone wool insulation really repels water. There will often be humidity in the air, particularly when you are chatting about crawlspaces and attics.

Becoming capable to repel that moisture away and eternally currently being a mildew and mildew-resistant solution, it is likely to assistance with the sturdiness of your wall assembly as effectively.

Attic Insulation

Dan: ROCKWOOL insulation batts arrive in 16-inch on center or 24-inch on middle by 47 or 48 inches prolonged, which is the best dimension for insulating attics. They healthy correctly concerning the studs, so you get that complete cavity insulation.

Step just one when putting in attic insulation is to inspect the existing insulation. Make confident there is no dampness, mould mildew, rodent droppings or rodents residing there. Rodents don’t primarily care for ROCKWOOL insulation. 

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

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

ROCKWOOL insulation generally has a 4.2 to 4.3 per inch R-worth, so you actually don’t will need fairly as much to hit the bigger R-value. However, we have merchandise with a higher R-worth generally for attics.

What About Seem Insulation?

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

The other component to sound insulation is friction in shape, how limited it fits in that wall cavity. If you have 1 spot that you can not insulate effectively, all the sound is likely via that a person area and you are reducing that seem insulation.
