Loose-Fill Insulation

• Loose-fill insulation is well suited for places where it is difficult to install other types of
insulation such as irregular shaped areas, around obstructions, and in hard to reach
places.

• Particularly useful for renovation and retrofit due to minimal disturbance of existing
interior or exterior finishes.

• Most cost effective way to add insulation into the attic of a home without having to
remove undamaged, existing insulation.

• Covers all ceiling joists that batts/rolls may leave exposed to prevent any potential
heat loss

• Any insulation can absorb moisture and be damaged if exposed to high humidity or
roof leaks.

• Loose-fill insulation that has been repeatedly saturated will lose much of its R-Value
and will need to be removed.

• Fluffing insulation only results in loss of R-value and enabling air to pass through
easily to create more heat loss.

Cellulose

• Cellulose loose-fill insulation is produced from recovered wood pulp materials
combined with newsprint & boxes that have been shredded and pulverized into small
fibrous particles and subsequently treated with boron based chemicals to make
material fire retardant.

• Cellulose is not subject to convective heat loss

• Cellulose is highly resistant to airflow because of density

• Cellulose loose-fill insulation settles more than other loose-fill insulations due to its
density which more effectively reduces air leakage.

• Newer cellulose insulation technologies “fiberizes” the newspaper, which breaks
down raw material into fluffier individual fibers for cleaner, less dusty insulation with a
higher R-value.

• Typical R-value of cellulose insulation is 3.7 per inch.

• Fire retardants in cellulose are nonhazardous.
