Which is better blown in fiberglass or cellulose?

Thereof, is blown in fiberglass better than cellulose?

Blown-in insulation is an excellent choice to insulate an existing attic because it can enhance the attic's R-value. 2.1 – 2.7 R per inch while Cellulose has an R-value of 3.5- 3.7 per inch. Cellulose is found to be more efficient at retaining its R-value across variety of temperatures than fiberglass.

Also Know, what type of blown in insulation is best? The best insulation options for an attic are open cell spray foam, fiberglass, and cellulose.

• Cellulose is the oldest insulation material used for not only the attic, but other areas of the home as well.
• Fiberglass is another traditional insulation material that consists of extremely fine glass fibers.

Accordingly, which is better insulation fiberglass or cellulose?

A given sample of cellulose insulation will provide better thermal performance than an identically sized sample of fiberglass insulation. Per square inch of insulation, cellulose has a higher R-value than fiberglass. With loose fill cellulose insulation, you can achieve an R-value of 3.2 to 3.8 per square inch.

What is the cost difference between cellulose and fiberglass insulation?

Loose-fill cellulose typically costs about $0.50 to $1 per square foot installed. The cost is similar to that of fiberglass batts but, if anything, slightly less. Damp-spray cellulose costs about $0.60 to $1.80 per square foot of wall space.
