Cellulose insulation has several advantages when compared to other forms of insulation. The most important advantage of cellulose insulation is its high thermal resistance. It is also the most cost-effective and environmentally friendly insulation available.

The thermal resistance of insulation is measured by R-value. R-value measures the ability of insulation material to resist heat transfer at a specified thickness. Products with a higher R-value can produce the greatest energy savings when properly installed. Cellulose insulation has a higher R-value per unit thickness than most comparable mineral fiber insulation materials including fiberglass.

Cellulose insulation provides several environmental benefits including the reduction of solid waste and the conservation of fuel due to its low embodied energy. Wastepaper is one of the largest solid waste disposal problems for many communities. Using more recycled products can help to mitigate this problem. Reports state that in 1994 the cellulose industry used approximately 840 million pounds of recycled newsprint. Cellulose insulation consists of 80% or more post-consumer recycled wastepaper, the highest recycled content compared to any other form of insulation.

The production of cellulose insulation requires less embodied energy than other forms of insulation. Less energy means less fuel, which means less of our natural resources are used. According to Environmental Building News it takes 750 BTUs to produce a pound of cellulose insulation, while a pound of fiberglass uses 12,000 BTUs. Using manufacturer's published coverage charts shows that cellulose insulation uses approximately an eighth of the embodied energy needed to make traditional fiberglass for the same R-value coverage.

Additionally, there are also several benefits for business owners who use cellulose insulation. Insulation increases the resale value of their property, makes their property more comfortable, and lowers their energy cost. With cellulose insulation these savings quickly pay for the cost of insulating.
