Or 7 inches of cellulose.
Cellulose attic insulation vs fiberglass.
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.
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.
Both cellulose and fiberglass insulation have their pros and cons but i feel that cellulose is the better bet overall.
The bottom line is that cellulose can burn but fiberglass will not support combustion.
Cellulose insulates better than fiberglass especially in very cold weather.
Thus creating a more energy efficient home.
Fiberglass insulation vs cellulose insulation.
Most people are more familiar with fiberglass than cellulose despite their similarities.
The two main least expensive and most commonly used residential insulation materials is cellulose and fibreglass.
Cellulose insulation vs fiberglass insulation comparison.
A fight for r value.
Good insulation lowers energy bills by trapping heat or cold air inside a building.
Although that represents just one brand.
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.
Picture the fluffy pink stuff.
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.
Blown in insulation is a versatile product that can be used throughout a home.
The trapped air molecules in the insulation are pulled up through the insulation into the colder attic air.
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.
Unless you opt for spray foam then the insulation choices normally come down to cellulose and fibreglass.
Fiberglass insulation also comes in colors like white and yellow.
It is able to improve energy efficiency home comfort and lower utility costs.
So what are the advantages and disadvantages of each of these.
You can get to the same place with either material.
