Energy reduction advantages:
Since the Energy Crisis of the mid-1970s, skyrocketing heating and cooling bills have underscored the importance of energy-efficient homes and conservation's role in holding down energy prices. Today, as in the 70s, adequately-insulated homes save homeowners money, conserve the country's vital energy resources, and inhibit demand-pull and rising energy costs. In addition to its energy saving capabilities, cellulose insulation is non-toxic, non-carcinogenic, and requires no special health warning labels.
High-density cellulose insulation carries a higher than average R-value that provides superb energy savings, reduced air infiltration, and long-term value and return on investment. As an added bonus, Cellulose Insulation is one of the greenest insulations with up to 85% American recycled materials
Cellulose insulation meets and often exceeds tough fire standards, providing increased safety and peace of mind. Cellulose insulation couples superior fire-resistance and air reduction with preeminent airborne sound abatement.
Cellulose insulation is the only wood-based building material that is treated with Boric Acid for fire retardancy, making it one of the safest materials used in home construction.
In the event of a fire, cellulose's dense structure and fire retardancy slow its spread through the building by blocking flames and hot gases while restricting the availability of oxygen in insulated walls and ceilings. Whereas the National Research Council Canada stated cellulose in the wall cavity provided an increase in the fire resistance performance of 22% to 55%, their findings on fiberglass showed the fire resistance of an assembly with glass fiber insulation was slightly lower than that of a non-insulated assembly. Tests at Omega Point Laboratories indicated that cellulose in a wall increased fire resistance from un-insulated walls from 26% to 77%. Several fire demonstrations show cellulose-insulated structures have remained virtually intact while un-insulated and fiber glass insulated structures burned to the ground.
Although numerous products tout confusing and misleading claims, cellulose remains superior in safely conserving energy in real world situations.
Spray-applied cellulose is used for applying cellulose to new wall construction. The differences are the addition of water to the cellulose while spraying as well as adding some kind of moisture retardant such as chlorine to prevent mold cultures. In some cases the insulation might also mix in a very small percentage of adhesive or activate a dry adhesive present in the cellulose. Wet-spray allows application without the need for a temporary retainer. In addition, wet-spray allows for an even better seal of the insulated cavity against air infiltration and eliminates settling problems. Wet-spray installation requires that the wall be allowed to dry for a minimum of 24 hours (or until maximum of 25% moisture is reached) before being covered.
