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.
Cellulose fiber attic.
1 an uninsulated structure.
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.
Attic card greenfiber provides outstanding thermal performance fire resistance and sound control.
You can get to the same place with either material.
R value means resistance to heat flow the higher the r value the greater.
Or 7 inches of cellulose.
Cellulose can slow down air flow particularly in walls.
Both cellulose and fiberglass need to be installed at the correct depth and density to achieve the intended r value.
Rather than trying to meticulously lay fiberglass insulation over the attic homeowners and builders can simply blow cellulose insulation throughout the attic.
The two main least expensive and most commonly used residential insulation materials is cellulose and fibreglass.
Consisting of up to 85 recycled content greenfiber insulation is specially treated for flame resistance.
It is allowed to settle over time.
The trapped air molecules in the insulation are pulled up through the insulation into the colder attic air.
Cellulose forms a dense continuous mat of insulation in your attic.
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.
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.
Unless you opt for spray foam then the insulation choices normally come down to cellulose and fibreglass.
So what are the advantages and disadvantages of each of these.
This keeps the air from moving within the insulation and from penetrations between the air conditioned space and the attic.
And 3 a structure insulated with greenfiber s cellulose insulation using spray applied cellulose insulation wall.
The cellulose is allowed to fill the cavities or blanket existing insulation.
2 as demonstrated by the large scale outdoor fire test program comparing.
The air trapped in the pockets of the insulation is part of what insulates your home.
Blown cellulose is typically the preferred choice of insulation for attics.
No pressure is placed on the cellulose.
Cellulose is more difficult to cheat than fiberglass.
2 a structure insulated with r 13 fiberglass batts wall cavities and blown in loose fill insulation attic floor.
The cellulose is blown into the attic or walls through long flexible tubes that run from the blower to an application nozzle.
