Nu-Wool Premium Cellulose Insulation vs. Fiberglass Insulation
Producing Nu-Wool Premium Cellulose Insulation is more energy efficient than manufacturing fiberglass insulation. Using Nu-Wool Premium Cellulose Insulation is more than a smart choice for its comfort and savings benefits, Nu-Wool is 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 10 times MORE energy to make fiberglass insulation than to produce cellulose insulation.

Since less energy is used to manufacture cellulose insulation, and less fuel is consumed in building using cellulose insulation, the atmospheric emissions which contribute to global warming are much reduced.
