Preferred insulation material for environmentally concerned builders and designers!

Cellulose Insulation

Applegate Insulation is a field-proven, advanced insulation system designed for use in wall cavities, attics and between floors.

Environmentally Preferred

Builders, architects, and insulation ontractors who influence the choice of insulation for many buildings have the opportunity to make a profound impact on the environment.

Thermal Performance

A mere 2% in voids and gaps associated with normal fiber glass batt installation can result in an actual decrease in thermal performance of 14-42% less than batt labeled R-value.

According to a study at the University of Colorado on cellulose insulation's superiority to fiberglass, Applegate Insulation achieves a tighter building cavity and is 26-38% more efficeint than fiberglass. Two structures were built-identical in every respect buy the insulation material. Blower door tests demonstrated that the structure filled with cellulose insulation was 36-38% tighter than the mineral fiber material, and the structure with cellulose insulation went on to use 26.6% less energy for heating.

With Applegate's high denisty and custom fit around obstacles, Apple Insulation is able to deliver and maintain it's effective R-Value against other forms of heat transfer through the building envelope (convection and radition) while, in comparison, other insulations perform poorly.

Recycled Content

Applegate Insulation is made with 85% recycled newsprint, an excellent, high-quality end-use for materials that may otherwise be dumped into landfills. In fact, insulating a 1,500 square foot home with cellulose insulation cycles as much newsprint as one individual will use in 40 years.

Manufacturing Energy

Manufacturing fiberglass to insulate the same-sized structure to the same R-value consumes 7 times more energy than it does to manufacture cellulose, and to manfucture polystyrene consumes as much as 30 times more energy.


Standing outside a cellulose plant, one can hear humming motors, but thee are no smoke plumes and no odors because there are virtually zero emissions.

Fiberglass is produced in large blast furnaces that burn natural gas generate, enormous amounts of chemicals (formaldehyde, urea, polyvinyl acretate, chlorides, etc.) and release greenhouse gases into the atmosphere.

Indoor Air Quality

The National Resources Defense Council states that "no adverse effects from cellulose have ever been identified". The dust from Applegate Insulation is no more toxic than the dust in a typical home. Perhaps that's why, the American Lung Association of Virginia has insulated their Breathe Easy Office Complex with Applegate.


Walls insulated with Applegate Insulation are extremely fire resistant. The International Fire Safety Code permits electrical boxes installed on opposite sides of an Applegate-filled wall to be separated by as little as 3.5 inches, while for fiberglass-insulated walls, required separation is 24 inches.

While the Gypsum Associate states that cellulose does "not adversely impact the fire resistive ability" of the stud partition system, additional tests have gone on to demonstrate that cellulose-insulated walls easily achieve a one-hour fire rating with just 1/2 inch type X gypsum board, increasing the fire resistance attributable to insulation by about 46%.

Because the dry-wet process used to make Applegate Insulation is more advanced than most other cellulose manufacturers, fire retardants are locked in so well that it would take over 300 years at unliable conditions for Applegate Insulation to lose its fire retardant ability.

Applegate Cellulose Insulation has been approved under some local building codes as a fireblocking product.


Applegate Insulation is a field-proven noise control insulation, absorbing substantial levels of unwanted sound. Because sound is often airborne, it will follow the same paths as air infiltration. But the sprated-in-place Applegate Insulation creates a monolithic barrier, sealing off voids and gaps that could easily transmit sound. Because of its high-density and seamless coverage, Applegate Insulation contributes to an excellent STC rating.
