Why use cellulose insulation?
At Eco Insulation we use cellulose insulation. The main reason we prefer blown fiber cellulose is because of its extremely high content of recycled material. Its made up of 85% recycled news paper that has been treated with boric acid and borate which makes cellulose flame resistant, pest resistant and mould resistant. Boric acid is a very weak acid, used as an antiseptic and insecticide and in the production of insulation materials. When installed, cellulose creates a monolithic blanket in your attic. It has the ability to fill gaps, nooks and cranny’s.
Cellulose is denser than fiberglass. When insulating your attic it’s important to keep that in mind. Fiberglass requires 18″ of product to achieve an R50. Cellulose achieves this in 13.5″ . This is really relevant when the perimeter of your attic has limited amount of space to add insulation. Older homes often times have a low roof pitch which restricts the amount of insulation that can be installed around the perimeter above the soffits. So at the eves you may only be able to achieve an R20 or lower. Yet another reason why use cellulose insulation.
Cellulose controls sound
Not only is cellulose a great product for insulating your home, shop or barn attic, its also great at reducing sound. STC is a number rating of a material’s ability to resist airborne sound transfer. The higher the STC rating the greater the sound absorption through a partition wall. visit this link to see test results. STC guidelines for cellulose insulation
The Big Burn Video
The video below displays the awesome power of cellulose in some field experiments, 3 structures are side by side, one is not insulated, the other is insulated with fiberglass insulation and the third with cellulose insulation. the non insulated and insulated fail at almost the exact same time while the cellulose house has a 25minute gap. 25 minutes in a house fire is life or death. Check out this video and see for your self why use cellulose insulation. Mould resistant, pest resistant, flame resistant cellulose insulation in a great choice when insulating your attic in a new home or existing attic top up.

Frequently Asked Questions
Cellulose insulation is considered one of the most environmentally friendly insulation materials because it’s made of 80 to 85% recycled newsprint. Learn More about Cellulose Insulation
Cellulose is composed of 75-85% recycled paper fiber, usually post-consumer waste newsprint. The other 15% is a fire retardant such as boric acid or ammonium sulphate. Cellulose has the highest recycled content of any insulation available. Learn More about Cellulose Insulation
Like many insulation materials, it provides an R-value of approximately R-3.5 per inch of thickness. But, air leakage through cracks, voids, and gaps is important, responsible for approximately one-third of an average home’s heat loss. Cellulose is a superb air-blocker.

20 to 30 years
Cellulose insulation has a typical lifespan of around 20 to 30 years. Since it is made of recycled newsprint, it will degrade over time, faster than fiberglass insulation. However, during its lifetime it does provide air-blocking properties that fiberglass does not. Learn More about Cellulose Insulation
