Cellulose Vs Fiberglass Attic

If you ve got bare uninsulated areas on the floor of your attic getting some kind of insulation in there is a must.

Cellulose vs fiberglass attic.

Better insulator sometimes cellulose and fiberglass batts typically have similar r values of about 3 2 to 3 8 per inch. Air moving through a vented attic deposits dirt and dust into fiberglass batts. Rather than trying to meticulously lay fiberglass insulation over the attic homeowners and builders can simply blow cellulose insulation throughout the attic. Because the loose particles blown in fill any and all odd shaped areas of the attic floor cellulose offers superior coverage without the need to custom fit pieces.

You can add batts in easy to access places such as the attic but not in between walls. Cellulose has an r factor of at least 3 8 per inch moderately higher than fiberglass batts. Thus creating a more energy efficient home. But which one should you pick.

Any insulation is better than no insulation. Fiberglass batts don t offer that flexibility. Cellulose provides better sound insulation than fiberglass i e homes are less noisy with it. Cellulose is the second most common.

Both fibreglass and cellulose are the two most inexpensive insulation products that you could use. Because it is denser than fiberglass cellulose is much more resistant to wind washing. Once installed in the attic cellulose loose fill insulation looks like mounds of freshly fallen snow covering the attic floor. In most houses around atlanta the choice of insulation material comes down to fiberglass vs.

This is called wind washing. Fiberglass insulation contains billions of tiny glass fibers which contain trapped bubbles of air. More consistent pricing from cellulose manufacturers than fiberglass. Fibreglass is perhaps the most common product available in the market for insulation outpacing its close competitor cellulose by 50 1.

Benefits of cellulose insulation. Compared to fiberglass cellulose is a superb air blocker. Cellulose insulation includes cellulose cells that have natural insulating power. Cellulose is easier to keep out of bird blocks and air conditioner condensate pans.

Fiberglass is the most common. As the temperature difference between the living space and attic increases the r value of blown fiberglass diminishes. It is made of shredded paper plus a fire retardant chemical known as a borate. Once it has settled fiberglass has an r value of 2 1 2 7 per inch while cellulose has an r value of approximately 3 0 per inch.

The manufacture of fiberglass is 80 more energy intensive than cellulose. Fiberglass is a suspected carcinogen. The paper is broken down into cellular fibers that provide insulation. Cellulose resists blowing when installed fiberglass tends to blow around stick to the attic ceiling and drift.

Both types of insulation can you know insulate. Loose fill blown fiberglass insulation has another slight problem.
