Cellulose Insulation Features

Cellulose insulation has a functional lifetime of more than 50 years!

There is no need to replace or maintain the insulation during normal building use. During the installation of loose-fill insulation, any waste material is added into the building shell where the insulation is installed, so there is effectively no installation waste.

Good for the environment!

Blown cellulose insulation is produced primarily from post-consumer wood pulp (newspapers), typically accounting for roughly 85 % of the insulation by weight. Cellulose insulation is treated with fire-retardant. Borates and boric acid are used most commonly and account for the other 15 % of the cellulose insulation by weight.

Extra Cellulose insulation Perks

Sound Control

Cellulose provides very effective sound control to minimize outside noises and between rooms (if the interior walls are insulated). Many people only focus on the energy savings that can be achieved with cellulose insulation but overlook the benefits that come from improved sound insulation. If you have ever walked into a house that is not insulated you will immediately notice that noises from outside of the house are “louder” than in an insulated home.

Fire safety

Besides saving you money, cellulose insulation also provides extremely effective fire protection capabilities.
Tests conducted by Underwriters Laboratories Inc.® show that Cellulose insulation provides an effective 1 hour fire rating. This will slow the spread of a fire allowing you more time to escape any danger. This is because cellulose is specially treated using Borate Compound Chemicals as a fire retardant in the manufacturing process to meet or exceed all fire safety requirements.


Mold Resistance

Cellulose significantly decreases the risk of mold even beginning to form. Not to mention cellulose has the lowest burn rate out of a insulation materials making it incredibly safe for you and your family.

Pest Control

Cellulose insulation is treated with boric acid, which is an efficient pest hindrance. When insects/pests absorb or come into contact with boric acid, it kills the creatures and they can not contaminate your insulation.

Air / Vapor Barrier

Air infiltration is almost as important as R-value in the thermal performance of a building. Infiltration of unconditioned ambient air means that heating and cooling systems must expend more energy to compensate for the infiltration.

Cellulose Insulation Tops Fiberglass in Standards

Cellulose Insulation is covered by the American Society for Testing and Materials Standard Specifications (ASTM). The ASTM covers several material properties, including:

  • R-Value
  • Flame spread
  • Smoldering combustion
  • Density
  • Corrosiveness
  • Odor emission
  • Moisture vapor absorption
  • Fungi resistance
  • Adhesive/cohesive strength (spray on only)

“Recently did my home. Tim and the Addison crew came out and did my attic properly as it should’ve been done the first time. Explained every single question (i had a lot) i had before and during the job. Tim made sure during the job they were doing the air sealing properly because that’s what makes the biggest difference in keeping the cool/heat in the house and so that it doesn’t get lost in translation somewhere in in the attic. Highly recommend and speak with Tim when doing work in your property!”

James is prompt, thorough, and personable — responded to my website inquiry right away and made it easy to schedule an appointment (still haven’t heard back from the competition — that was three days ago). He provided a detailed and professional quote within minutes of being on site and saved me from spending $20k on an unnecessary new roof! I’m glad I contacted Green Attic.

Tim and his crew then came out to remove the old insulation, clear/kill all the mold in the attic, remedy issues that were causing the mold in the first place (insufficient ventilation and blocked soffits), and finally re-insulate our attic/basement. The work was intense, but Tim’s transparency with the process and willingness to educate us on the problems that we were having were what sold us. We also appreciated that Tim was able to work in some added value into his services without charging us the difference.
