One of the biggest concerns today is with Mold. Mold, mildew, and fungus can cost you thousands of dollars in home repairs. You can rest assured that when you chose Rockwool Premium PlusT Insulation this will not be an issue. Because Rockwool Premium Plus™ is an inorganic material it will not sustain mold, mildew, or fungus growth.

Unlike cellulose and open cell foam (which has been shaved off at the wall) Rockwool Premium Plus™ will not absorb moisture. There are several issues associated with these products:

• Cellulose is blown in wet similar to that of Rockwool Premium Plus™, but the major difference is that the fibers in cellulose absorb the water and can take up to 8 days to dry. A pit fall is that the outside feels dry while the inside is still moist. Because it feels dry to the touch the drywall contractor installs the drywall over it trapping the moisture in the wall potentially causing a mold and mildew issue. Rockwool Premium Plus™ in a 2 x 4 wall can be covered in 24 hours, 2 x 6 in 48.

• Cellulose when blown in too wet will settle at a much faster rate, and at a larger percentage. Test have shown that over a three year period Cellulose can settle by as much as 19%. For more information regarding this study read the ASTM 1030 in the download section of this page.
• Cellulose uses Boric Acid to achieve its flame retardency. When you combine Boric Acid with water you have a corrosive mixture that can potential corrode pipes.
• Open Cell Foam when shaved off flush with the studs becomes a sponge. This could potentially pose a problem if you had a pipe leak and the foam soaked up the water until the entire wall was saturated and you were unaware of the leak to begin with. If this were to happen the entire wall would have to be removed and rebuilt, because of the potential for mold growth on the drywall and the exterior sheathing.
