Compared to fiberglass cellulose is a superb air blocker.
Cellulose vs fiberglass attic.
Fiberglass is the most common.
Cellulose is easier to keep out of bird blocks and air conditioner condensate pans.
Fiberglass is a suspected carcinogen.
The paper is broken down into cellular fibers that provide insulation.
Any insulation is better than no insulation.
Better insulator sometimes cellulose and fiberglass batts typically have similar r values of about 3 2 to 3 8 per inch.
Air moving through a vented attic deposits dirt and dust into fiberglass batts.
Because it is denser than fiberglass cellulose is much more resistant to wind washing.
Fiberglass insulation contains billions of tiny glass fibers which contain trapped bubbles of air.
You can add batts in easy to access places such as the attic but not in between walls.
Cellulose is the second most common.
Cellulose resists blowing when installed fiberglass tends to blow around stick to the attic ceiling and drift.
This is called wind washing.
More consistent pricing from cellulose manufacturers than fiberglass.
Both fibreglass and cellulose are the two most inexpensive insulation products that you could use.
Thus creating a more energy efficient home.
Benefits of cellulose insulation.
Rather than trying to meticulously lay fiberglass insulation over the attic homeowners and builders can simply blow cellulose insulation throughout the attic.
Once installed in the attic cellulose loose fill insulation looks like mounds of freshly fallen snow covering the attic floor.
As the temperature difference between the living space and attic increases the r value of blown fiberglass diminishes.
If you ve got bare uninsulated areas on the floor of your attic getting some kind of insulation in there is a must.
The manufacture of fiberglass is 80 more energy intensive than cellulose.
Once it has settled fiberglass has an r value of 2 1 2 7 per inch while cellulose has an r value of approximately 3 0 per inch.
Dirty fiberglass batts have a significantly reduced r value.
Cellulose insulation includes cellulose cells that have natural insulating power.
Loose fill blown fiberglass insulation has another slight problem.
But which one should you pick.
Cellulose provides better sound insulation than fiberglass i e homes are less noisy with it.
Fiberglass batts don t offer that flexibility.
It is made of shredded paper plus a fire retardant chemical known as a borate.
In most houses around atlanta the choice of insulation material comes down to fiberglass vs.
Cellulose has an r factor of at least 3 8 per inch moderately higher than fiberglass batts.
Because the loose particles blown in fill any and all odd shaped areas of the attic floor cellulose offers superior coverage without the need to custom fit pieces.
Both types of insulation can you know insulate.
