Building insulation is low- thermal-conductivity material used to cut back building warmth loss and acquire, and cut back noise transmission. In some conditions this might depart areas of wall uninsulated. Cellulose is approximately three times denser than fiberglass, offering a slight improvement in sound reduction. Many cellulose companies use a blend of ammonium sulfate and borate.

In comparison with closed cell, Polyurethane foam insulation (R=5.5 to 6.5 per inch), cellulose has a decrease R-worth per inch, but is much less expensive; foam has the next value per equal R-value. In some areas it can be troublesome to find installers which might be experienced with cellulose. With appropriate training in set up strategies and quality control methods that is ruled out by putting in to tested densities preventing any future settlement.

Other than some constraints created by a shortage of boric acid to be used as hearth retardant, cellulose captured an increased share of the market because of lower costs and its suitability for retrofits. 4 major sorts of unfastened-fill cellulose merchandise have been developed below a variety of brand names.
