Cellulose Attic Insulation Vs Fiberglass

Blown in insulation is a versatile product that can be used throughout a home.

Cellulose attic insulation vs fiberglass.

Rather than trying to meticulously lay fiberglass insulation over the attic homeowners and builders can simply blow cellulose insulation throughout the attic. This allows the insulation to get into the small pockets and crevices that fiberglass wouldn t be able to. Thus creating a more energy efficient home. Fiberglass insulation also comes in colors like white and yellow.

The two main least expensive and most commonly used residential insulation materials is cellulose and fibreglass. A fight for r value. When using cellulose blown in dry insulation it requires a machine to achieve its purpose and a training session from wherever you rent the blower from. Most people are more familiar with fiberglass than cellulose despite their similarities.

Cellulose wins last update. Good insulation lowers energy bills by trapping heat or cold air inside a building. Both cellulose and fiberglass insulation have their pros and cons but i feel that cellulose is the better bet overall. You can get to the same place with either material.

Cellulose insulation vs fiberglass insulation comparison. Fiberglass insulation vs cellulose insulation. The trapped air molecules in the insulation are pulled up through the insulation into the colder attic air. Picture the fluffy pink stuff.

If fiberglass batts become compressed losing some of their air pockets then this insulation may be more affected by air flow than cellulose which performs well regardless of density. This problem has been successfully solved by installing fiberglass batt insulation over the top of loose fill or blown insulation. The bottom line is that cellulose can burn but fiberglass will not support combustion. Assuming your current attic insulation is made from fiberglass and has a value of r 13 you d have to add roughly 10 inches of additional fiberglass to hit r 38.

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.

Fiberglass is the most popular type of insulation partially because it has been around so long. When used in an attic space however both types of insulation are ineffective at air flow across the attic floor such as a strong gust of wind.

It is able to improve energy efficiency home comfort and lower utility costs. Unless you opt for spray foam then the insulation choices normally come down to cellulose and fibreglass. Or 7 inches of cellulose.
