Fiberglass fibers may become airborne which can be considered a pollutant.
Cellulose insulation in attic vs fiberglass.
Attic blown cellulose is typically the preferred choice of insulation for attics.
Cellulose insulation is considered a greener material than fiberglass.
Both fibreglass and cellulose are the two most inexpensive insulation products that you could use.
Fibreglass is perhaps the most common product available in the market for insulation outpacing its close competitor cellulose by 50 1.
Rather than trying to meticulously lay fiberglass insulation over the attic homeowners and builders can simply blow cellulose insulation throughout the attic.
It does not pollute the air during manufacture or use as much energy to produce as fiberglass.
