Cellulose forms a dense continuous mat of insulation in your attic.
Cellulose attic insulation vs fiberglass.
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.
The two insulations have successfully improved energy efficiency in homes over the years.
This allows the insulation to get into the small pockets and crevices that fiberglass wouldn t be able to.
Both cellulose and fiberglass are two most commonly used insulations.
A given sample of cellulose insulation will provide better thermal performance than an identically sized sample of fiberglass insulation.
A study by the university of colorado found that cellulose insulation reduced air leakage by 38.
Fiberglass insulation cons air leakage fiberglass doesn t do much at all to slow the flow of air while cellulose has some success.
Cellulose insulation like spray foam insulation limits air movement.
Not ideal for extreme cold the r value of fiberglass lowers considerably in extremely cold climates making cellulose a better choice.
Both fibreglass and cellulose are the two most inexpensive insulation products that you could use.
Cellulose provides better sound insulation than fiberglass i e homes are less noisy with it.
It is made from paper that has a minimum of 85 recycled content such as newspaper.
This keeps the air from moving within the insulation and from penetrations between the air conditioned space and the attic.
Fiberglass insulation cannot stop air from passing through it meaning that more than 30 of heat or air conditioning can escape.
Cellulose vs fiberglass insulation.
Cellulose is more difficult to cheat than fiberglass.
Air leaks can eventually lead to problems with moisture and condensation.
Cellulose insulation is considered a greener material than fiberglass.
With varying locations and building code requirements fiberglass and cellulose insulation can be beneficial for homeowners builders and remodelers.
Fiberglass is a suspected carcinogen.
Cellulose has 38 better air infiltration than fiberglass.
Sources many fiberglass installers fluff the fiber with extra air so you don t get as much insulation as you re supposed to.
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.
Thus creating a more energy efficient home.
Fibreglass is perhaps the most common product available in the market for insulation outpacing its close competitor cellulose by 50 1.
