Ajax Roofing also installs cellulose attic insulation - this product is superior to fiber glass insulation.
Cellulose insulation is a type of loose-fill insulation made from recycled wood fiber, primarily waste newspaper and cardboard. The wood fiber, which is composed of cellulose, is shredded and pulverized into small, fibrous particles that pack tightly into closed building cavities, inhibiting airflow. This provides a thermal resistance of R-3.6 to R-3.8 per inch.
Manufacturers add chemicals to the cellulose to make it insect and fire resistant.

The NRDC has concluded the following:
- Cellulose insulation manufactured from recycled paper is the least polluting and most energy efficient insulation.
- Cellulose has the highest post-consumer recycled content. The fiberglass industry averages 35% recycled glass, while the cellulose industry averages a minimum of 75% recycled content.
- It takes more than 10 times as much energy to produce fiberglass insulation as cellulose insulation.
- Due to air circulation and natural convection, the R-value of blown-in fiberglass insulation decreases by as much as 50% as the temperature drops from 45 degrees F to 18 degrees F.
- Cellulose has better resistance to air flow and prevents the upward movement of air caused by temperature differences (the R-value of cellulose actually improves during cold weather).
- Substantial and well-documented public health threats are associated with fiberglass.
- No adverse health effects from cellulose insulation have been identified.
