More about Unfaced Cellulose/Cotton Batt Insulation

Cellulose-based insulation products can use a variety of cellulose fibers. This CP covers the cellulose-based batt insulation products on the market at the time of this research which include two recycled denim batt insulations and one primarily recycled newspaper batt insulation. The products are similar in terms of make-up, differing primarily in the source and type of cellulose (cotton versus paper). These insulations contain a high quantity of recycled content which can be post-industrial or post-consumer cotton and denim fibers and/or post-consumer recycled newspaper. Recycled content ranges from a minimum of 70-85%. The cellulose fibers are bound using binder fibers, which are distributed through the cellulose fiber have a low enough melting point to melt and a bond to each other, holding the form of the batt. Flame retardants are needed in order to meet fire code requirements. These are typically boric acid and ammonium sulfate, but one manufacturer uses an alternative of ammonium phosphate salt. Hazardous residuals from the denim production process are possible in the recycled cotton, but could not be verified or quantified in the insulation based on the information available.
