Using Nu-Wool Engineered Cellulose Insulation
is more than a smart choice for its comfort and savings benefits, Nu-Wool is also environmentally friendly even in the manufacturing process. Fiberglass insulation is made by melting sand and recovered glass in gas-fired furnaces.
It takes at least 8,500 BTU's of energy to produce a pound of fiberglass insulation. Cellulose insulation
is produced by processing post-consumer recovered paper through electrically driven mills.
Estimates for the embodied energy of a pound of cellulose vary from 150 to 750 BTU's. Converting this to BTU's-per-R, it takes at least 40 times more energy to make fiberglass insulation than to produce cellulose insulation.
