Why should I choose WeathershieldTM Cellulose instead of fiberglass insulation?
The most significant difference between cellulose and fiberglass is density – cellulose is three times as dense as fiberglass, therefore, cellulose offers a higher R-Value per inch and greater resistance to air leakage. Cellulose completely fills cavities, leaving few air pockets for air or sound to travel in. Cellulose is also a more environmentally friendly product that fiberglass. Made from recycled paper, it has up to ten times less embodied energy (energy used in production and transportation) than fiberglass. Cellulose is made up of 85-100% recycled paper sources, while the recycled content of fiberglass insulation ranges from 0-40%.
