Stone wool insulation is fireplace-resistant and non-flamable, providing your loved ones far more time to securely escape a household 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 (plentiful in the earth), and slag is a by-item of the steel and copper market. The minerals are melted and spun into fibers.

ROCKWOOL solutions incorporate involving 16% or 40% pre-buyer recycled materials dependent on the ROCKWOOL production facility place.

The quantity of recycled articles is optimized to present the best thermal, acoustic, and fire defense attributes from ROCKWOOL products, when still maximizing the recycled material.

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

So, our solution is comparatively new to North America, but historically it is been all-around for rather some time now. We just opened up a new superior manufacturing facility in Ranson, West Virginia. 

All of our factories are zero waste-to-landfill, and mainly because stone wool insulation is hydrophobic, we use recycled rainwater to minimize it. Even our factories that are wind- and h2o-driven are self-building.

Rewards of Stone Wool Insulation

Not only is Rockwool insulation particularly hearth-resistant, it also works to consist of fire and prevent its distribute. (Rockwool)

Dan: ROCKWOOL stone wool insulation is obviously hearth-resistant simply because it is made from rock. We do not have to increase any fire retardants or substances that improve flammability, so it is never ever likely to carry a flame and has zero smoke enhancement.

A different benefit is mildew resistance. ROCKWOOL stone wool insulation truly repels h2o. There will often be humidity in the air, specially when you’re conversing about crawlspaces and attics.

Staying capable to repel that moisture away and permanently being a mould and mildew-resistant product or service, it is going to aid with the sturdiness of your wall assembly as effectively.

Attic Insulation

Dan: ROCKWOOL insulation batts appear in 16-inch on middle or 24-inch on heart by 47 or 48 inches very long, which is the ideal measurement for insulating attics. They match perfectly concerning the studs, so you get that comprehensive cavity insulation.

Move 1 when installing attic insulation is to examine the existing insulation. Make certain there is no humidity, mould mildew, rodent droppings or rodents residing there. Rodents do not largely treatment for ROCKWOOL insulation. 

Following inspection, merely lay the batts down perpendicular to the joists, particularly if the current insulation is only to the joists.

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

ROCKWOOL insulation normally has a 4.2 to 4.3 for every inch R-worth, so you actually really do not will need rather as considerably to hit the greater R-worth. On the other hand, we have goods with a larger R-worth largely for attics.

What About Seem Insulation?

Dan: The finest matter for seem insulation is density and mass, both of which ROCKWOOL has. 

The other element to sound insulation is friction suit, how tight it suits in that wall cavity. If you have one particular region that you can not insulate thoroughly, all the seem is heading by way of that 1 section and you are decreasing that audio insulation.
