Benefits of Cellulose
Cellulose is manufactured from recycled paper and is the least polluting and most energy efficient insulation (besides spray foam insulation). It has the highest post-consumer recycled content with an average of 75% of the content being recycled. And in comparison to fiberglass, it takes 10x less energy to produce and manufacture.
Better Heat Resistance Value
Due to air circulation and natural convection, the R-value (heat resistance value) is a higher in cellulose than fiberglass.
Better Air Resistance
Besides spray foam insulation, cellulose provides better air resistance to air flow and prevents upward movement of air caused by temperature differences. So in Layman’s terms, air cannot travel as easily through cellulose, which makes it a better air sealant.
