Cellulose Insulation


Cellulose insulation is one of two types of blown-in insulation. It is composed of up to 85% recycled newsprint. The remaining content is most commonly a mixture of ammonium sulfate and borate that functions as a fire retardant. These chemicals have the added benefit of deterring insects, rodents and mold. Because Blown-in insulation is loose material it can take any shape and fits easily into oddly shaped spaces like vaulted ceilings. Also, because it can actually be blown into attics and walls without much disturbance for the homeowner or damage to the home, it is great for older homes.

Types of Cellulose Insulation

There are two types of this insulation. Our team of experts will determine the ideal choice for your situation.

Dry Pack Cellulose—With Dry Pack, the wall/ceiling is covered with “netting” that tightly contains the material in each cavity and eliminates settling.
Spray Applied Cellulose—Spray Applied Cellulose is different because the cellulose is mixed with latex adhesive, misted with water to activate the glue and blown into wall cavities.

How Is Blown-In Cellulose Insulation Applied?

Cellulose blown-in insulation must be applied using an insulation blowing machine. It is designed for both open-blow applications (such as attic spaces) and closed-cavity applications (such as walls or vaulted ceilings). Blown-in insulation creates a tight fit in each stud cavity and seals around all outlets, pipes, wires, etc.

Why Blown-In Cellulose Insulation?

  • It is very easy to install in open wall spaces.
  • The tight seals it creates brings increased noise control and a dramatic reduction in your heating and cooling costs.
  • You can take advantage of the rebates and tax credits from utility companies and the federal government.

If your home is more than 10 years old, it is most likely under insulated. Let our team of experts help you determine the ideal choice for you and your home or other building.
