What is the white fluffy insulation in my attic?
Likewise, what is the fluffy stuff in the attic?
Cellulose insulation looks like dirty cottony paper-pulp. You are also lucky if you have fiberglass (that pink cotton-candy-looking stuff.) These, fortunately, are the most likely things you will see in your attic floor, besides dust. You might find one of the older insulating materials, UFFI.
Subsequently, one may also ask, what is white insulation?
Northern White Fibre Glass Blowing Insulation is used in residential and commercial construction as a thermal and acoustical insulation. This insulation contains no asbestos, perlite, vermiculite or phenol-formaldehyde binder. These insulation products may qualify for energy tax credits.
If this sounds like what you have, it is likely cellulose insulation, which contains a higher amount of recycled paper, without minerals. This means cellulose insulation does not contain asbestos and is a safe insulation, blown into the cavities.
