Cellulose Insulation

Cellulose Insulation is one of the greenest products in the world. Cellulose is made from recycled newsprint and other paper sources, paper that might otherwise end up in landfills, releasing greenhouse gases as it decomposed.

Cellulose insulation forms a seamless blanket of natural fibers that provide outstanding protection against extreme heat and cold. On the hottest and coldest days, cellulose won't lose its effective R-value.

As an air barrier

Cellulose blocks air leakage through cracks, voids and gaps efficiently, only surpassed by sprayed foams. When installed in dense-pack format (3.5#/ cu ft) it is also an approved vapor barrier.

For sound attenuation

If the project goal is noise reduction, there is nothing better than cellulose, and the denser the application the better. Cellulose makes for highly effective sound attenuation in both exterior and interior walls, and between floors too.

Wet or dry application?

Our “wet” applied cellulose adds a fine mist of water to the cellulose material as it exits the gun tip, activating the natural starches in the material making it stick to walls. The bays are over-filled with cellulose, and the excess is shaved off and fed back to the blowing machine so it can be recycled in a closed-loop system.  Wet cellulose however cannot be applied to roof systems, as gravity will cause it to separate and pull away from the sheathing.

Our “dry” applied cellulose is for loose fill in attics, often applied directly over existing fiberglass. It is also blown into “closed” wall cavities and is referred to as “dense pack” (3.5#/ sq ft). It is not necessary for the material to be “sticky” because it is contained between the interior sheet rock and the exterior wall sheathing.  It can also be applied to roof systems with the use of a fabric netting to hold it in place.
