Cellulose Fiber Attic

The bottom line is that cellulose can burn but fiberglass will not support combustion.

Cellulose fiber attic.

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. Blown cellulose is typically the preferred choice of insulation for attics. Rather than trying to meticulously lay fiberglass insulation over the attic homeowners and builders can simply blow cellulose insulation throughout the attic. Cellulose can slow down air flow particularly in walls.

The two main least expensive and most commonly used residential insulation materials is cellulose and fibreglass. 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. R value means resistance to heat flow the higher the r value the greater. 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.

No pressure is placed on the cellulose. 1 an uninsulated structure. It is allowed to settle over time. 2 as demonstrated by the large scale outdoor fire test program comparing.

Walls are patched up and painted over. This problem has been successfully solved by installing fiberglass batt insulation over the top of loose fill or blown insulation. Cellulose is more difficult to cheat than fiberglass. Both cellulose and fiberglass need to be installed at the correct depth and density to achieve the intended r value.

This keeps the air from moving within the insulation and from penetrations between the air conditioned space and the 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. And 3 a structure insulated with greenfiber s cellulose insulation using spray applied cellulose insulation wall. You can get to the same place with either material.

The cellulose is blown into the attic or walls through long flexible tubes that run from the blower to an application nozzle. The trapped air molecules in the insulation are pulled up through the insulation into the colder attic air. Consisting of up to 85 recycled content greenfiber insulation is specially treated for flame resistance. Cellulose forms a dense continuous mat of insulation in your attic.

Or 7 inches of cellulose. The cellulose is allowed to fill the cavities or blanket existing insulation. The air trapped in the pockets of the insulation is part of what insulates your home. 2 a structure insulated with r 13 fiberglass batts wall cavities and blown in loose fill insulation attic floor.
