Cellulose
Cellulose Comes In Two Styles:
Higher R-value
Cellulose insulation is an efficient air locking method that prevents heat loss in homes up to 40% more than fiberglass insulation. The R-value of cellulose material averages 3.5 per square inch while fiberglass has 2.0 per square.
Safer
Cellulose insulation is made of paper and infused with a naturally occurring mineral, borate, an effective fire retardant. Borate gives cellulose a Class A fire rating, helping limit the spread of a fire and produces no smoke.
Quieter
Aside for the thermal efficiency, cellulose insulation can also provides very effective sound proofing, reducing external noise such as cars, aircrafts, push mower, etc. Cellulose insulation has a better the sound transmission coefficient rating than either fiberglass or foam, two of the most common insulating materials. That means a building insulated with cellulose will be very quiet.
Drier
The added borate in cellulose makes it a mold and mildew inhibitor to prevent moisture related issues.
Vermin Resistant
Borate is a non-irritant, non-toxic and allergy free agent that prevents vermin and insect breeding by causing their bodies to dehydrate when in contact with the cellulose insulation.
Environment Friendly
Cellulose uses 100% recycled newspaper fibers, paper that might otherwise end up in a landfill. Fiberglass has a maximum of 40% recycled content and foam products little or none. Fiberglass and foam residue are discarded in a landfill and won’t decompose.
