Cellulose Fiber Attic

The cellulose is allowed to fill the cavities or blanket existing insulation.

Cellulose fiber attic.

This keeps the air from moving within the insulation and from penetrations between the air conditioned space and the attic. The bottom line is that cellulose can burn but fiberglass will not support combustion. Unless you opt for spray foam then the insulation choices normally come down to cellulose and fibreglass. Rather than trying to meticulously lay fiberglass insulation over the attic homeowners and builders can simply blow cellulose insulation throughout the attic.

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. The two main least expensive and most commonly used residential insulation materials is cellulose and fibreglass. The air trapped in the pockets of the insulation is part of what insulates your home. Walls are patched up and painted over.

Consisting of up to 85 recycled content greenfiber insulation is specially treated for flame resistance. And 3 a structure insulated with greenfiber s cellulose insulation using spray applied cellulose insulation wall. Blown cellulose is typically the preferred choice of insulation for attics. Both cellulose and fiberglass need to be installed at the correct depth and density to achieve the intended r value.

The trapped air molecules in the insulation are pulled up through the insulation into the colder attic air. Cellulose is more difficult to cheat than fiberglass. You can get to the same place with either material. Cellulose forms a dense continuous mat of insulation in your attic.

No pressure is placed on the cellulose. It is allowed to settle over time. 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. 2 as demonstrated by the large scale outdoor fire test program comparing.

R value means resistance to heat flow the higher the r value the greater. Or 7 inches of cellulose. This problem has been successfully solved by installing fiberglass batt insulation over the top of loose fill or blown insulation. Cellulose can slow down air flow particularly in walls.

So what are the advantages and disadvantages of each of these. 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. The cellulose is blown into the attic or walls through long flexible tubes that run from the blower to an application nozzle. Attic card greenfiber provides outstanding thermal performance fire resistance and sound control.
