Fiberglass insulation contains billions of tiny glass fibers which contain trapped bubbles of air.
Attic cellulose insulation vs fiberglass.
Both cellulose and fiberglass are two most commonly used insulations.
Attic blown cellulose is typically the preferred choice of insulation for attics.
Cellulose provides better sound insulation than fiberglass i e homes are less noisy with it.
The two insulations have successfully improved energy efficiency in homes over the years.
It is made of shredded paper plus a fire retardant chemical known as a borate.
Because it is denser than fiberglass cellulose is much more resistant to wind washing.
Cellulose forms a dense continuous mat of insulation in your attic.
With varying locations and building code requirements fiberglass and cellulose insulation can be beneficial for homeowners builders and remodelers.
Cellulose insulation includes cellulose cells that have natural insulating power.
Sources many fiberglass installers fluff the fiber with extra air so you don t get as much insulation as you re supposed to.
Assuming your current attic insulation is made from fiberglass and has a value of r 13 you d have to add roughly 10 inches of additional fiberglass to hit r 38.
To hit code minimums you ve got to add new insulation on top of the old insulation.
Fibreglass is perhaps the most common product available in the market for insulation outpacing its close competitor cellulose by 50 1.
Cellulose insulation is considered a greener material than fiberglass.

Rather than trying to meticulously lay fiberglass insulation over the attic homeowners and builders can simply blow cellulose insulation throughout the attic.
Both fibreglass and cellulose are the two most inexpensive insulation products that you could use.
You can get to the same place with either material.
Dirty fiberglass batts have a significantly reduced r value.
Or 7 inches of cellulose.
It is made from paper that has a minimum of 85 recycled content such as newspaper.
Fiberglass is a suspected carcinogen.
Air moving through a vented attic deposits dirt and dust into fiberglass batts.
This keeps the air from moving within the insulation and from penetrations between the air conditioned space and the attic.
Fiberglass insulation is the easiest insulation product on the market to install and if installed correctly the most effective product on the market for home attic insulation.
When using cellulose blown in dry insulation it requires a machine to achieve its purpose and a training session from wherever you rent the blower from.
This is called wind washing.
Cellulose vs fiberglass insulation.
Fiberglass fibers may become airborne which can be considered a pollutant.
