BLOWN IN CELLULOSE
What is it made of? The short answer: Paper. While cellulose insulation has been used for many years, it really wasn’t until the 1970s that it came into wide-spread use in the U.S. and other developed countries. Strictly speaking, it can come from any cellular plant source (corncobs, sisal, sawdust, etc.), but generally it is made from recycled newspapers, cardboard, office paper, and the like which is then treated with borates which are a Class 1 fire retardant. Cellulose is commonly used as a cheaper upfront cost alternative to Spray Foam Insulation.
Key Benefits of Cellulose Insulation
Cellulose insulation provides the thermal performance by preventing radiant, conductive and convective heat loss. It fits snuggly into tight corners and around poles and pipes, which means fewer air pockets can form making it harder for heat to escape.
Treated with boric acid, which increases fire resistance, resists mold and makes it unpalatable to insects.
Cellulose installation is environmentally friendly
Reduces the noise that passes through between rooms as well as from outside.
