Rather than trying to meticulously lay fiberglass insulation over the attic homeowners and builders can simply blow cellulose insulation throughout the attic.
Cellulose insulation in attic vs fiberglass.
Fibreglass is perhaps the most common product available in the market for insulation outpacing its close competitor cellulose by 50 1.
It does not pollute the air during manufacture or use as much energy to produce as fiberglass.
Fiberglass fibers may become airborne which can be considered a pollutant.
It is made from paper that has a minimum of 85 recycled content such as newspaper.
A given sample of cellulose insulation will provide better thermal performance than an identically sized sample of fiberglass insulation.
Attic blown cellulose is typically the preferred choice of insulation for attics.
