ROCKWOOL items have between 16% or 40% pre-buyer recycled product dependent on the ROCKWOOL production facility place.

The volume of recycled information is optimized to provide the great thermal, acoustic, and hearth defense properties from ROCKWOOL products, even though however maximizing the recycled articles.

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

So, our product or service is rather new to North America, but traditionally it’s been all-around for pretty some time now. We just opened up a new innovative factory in Ranson, West Virginia. 

All of our factories are zero waste-to-landfill, and due to the fact stone wool insulation is hydrophobic, we use recycled rainwater to slice it. Even our factories that are wind- and drinking water-powered are self-creating.

Advantages of Stone Wool Insulation

Not only is Rockwool insulation very hearth-resistant, it also performs to have hearth and stop its distribute. (Rockwool)

Dan: ROCKWOOL stone wool insulation is normally hearth-resistant because it is created from rock. We don’t have to insert any fireplace retardants or chemicals that enhance flammability, so it’s never ever heading to have a flame and has zero smoke enhancement.

A different benefit is mould resistance. ROCKWOOL stone wool insulation actually repels drinking water. There will generally be humidity in the air, specially when you’re chatting about crawlspaces and attics.

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

Move 1 when setting up attic insulation is to examine the present-day insulation. Make guaranteed there is no humidity, mould mildew, rodent droppings or rodents dwelling there. Rodents really do not mostly treatment for ROCKWOOL insulation. 

Right after inspection, simply just lay the batts down perpendicular to the joists, particularly if the existing insulation is only to the joists.

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

ROCKWOOL insulation commonly has a 4.2 to 4.3 per inch R-benefit, so you truly never need really as significantly to strike the higher R-worth. On the other hand, we have merchandise with a bigger R-value mainly for attics.
