Fiberglass fibers may become airborne which can be considered a pollutant.
Cellulose insulation in attic vs fiberglass.
Cellulose insulation is considered a greener material than fiberglass.
Fibreglass is perhaps the most common product available in the market for insulation outpacing its close competitor cellulose by 50 1.
A given sample of cellulose insulation will provide better thermal performance than an identically sized sample of fiberglass insulation.
It does not pollute the air during manufacture or use as much energy to produce as fiberglass.
Both fibreglass and cellulose are the two most inexpensive insulation products that you could use.
Attic blown cellulose is typically the preferred choice of insulation for attics.
