Cellulose Insulation
The use of cellulose insulation is currently increasing because studies have suggested it can protect a structure from fire damage better than fiberglass and it is the greenest form of insulation.
Many types of cellulosic materials were used in the past, such as cardboard, cotton, straw, sawdust, hemp and corncob. Today, cellulose insulation is made with recycled newspaper. Machines grind and remove dust, a fire retardant is added and government standards guide proper installation of the finished product. Today, insulating a typical 1,500 sq. ft. ranch-style home with cellulose recycles as much newsprint as an individual will consume in 40 years.
At Henges Insulation, we install all these forms of cellulose. We have chosen to install GreenFiber’s Cocoon cellulose insulation because they have the most technologically-advanced and proven manufacturing facilities in the United States.
Types of Cellulose Insulation:
There are four major types of loose-fill cellulose products, each best for different parts of a structure and for different reasons.
- Dry Cellulose (Loose-Fill) – Blown into holes in walls during retrofits or blown into a new wall construction with the use of temporary retainers or netting. An experienced installer can dense-pack install by placing pressure on the cavity to further reduce settling and minimize gaps.
- Spray-Applied Cellulose (Damp-Spray) – Used for new wall construction. This form requires expensive equipment that adds water to the cellulose while spraying it. Sometimes, installers mix in small amounts of liquid adhesive or the added water activates a dry adhesive present in the cellulose. Damp-spray installation seals walls better but requires a minimum dry time of 24 hours, or until a 25 percent or less moisture level is reached.
- Stabilized Cellulose – Ideal for attic and roof insulation, especially with sloped roofs. A small amount of water is applied during installation that activates an adhesive. Less cellulose is needed and the overall weight of the product on the ceiling drywall is less, which can help prevent possible sag.
- Low-Dust Cellulose – Simple dust masks are recommended during the installation of any form of cellulose because a nuisance amount of dust is emitted. Low-dust cellulose has a small percentage of oil or dust dampener added. It is recommended for homes where someone is sensitive to newsprint or paper dust, though new dust will not be created after installation is complete.
