ABOUT OUR PRODUCT
Cellulose Insulation
Modern cellulose insulation dates from the 1920's and came into general use during the post World War II building boom. Cellulose insulation was used extensively in electrically-heated homes during the 1950's, as it was the only insulation that made them affordable to heat. It is an established, time-proven building material.
Cellulose insulation has been mistakenly regarded as a fairly low-tech material. In fact, with the new, light density mills, chemical pulverizers, and electronic bagging systems that became available in the 1990's (all currently in use at National Fiber), the cellulose process technology is actually quite sophisticated.
Cellulose insulation has been proven in numerous industry sponsored (as well as government and third party sponsored) tests to be at least 40% more effective as both a thermal insulator and a sound barrier than fiberglass. In fact, at temperatures below freezing, the thermal effectiveness of fiberglass falls precipitously, while cellulose maintains its effectiveness. Cellulose is less expensive to install than fiberglass. Cellulose provides significant, on-going savings vs. fiberglass on the cost of home energy. Cellulose insulation is environmentally friendly, as it is made almost entirely of re-cycled materials; the production process for fiberglass requires huge amounts of energy.
In all applications, bags of cellulose insulation are placed in an industrial-quality blowing machine. The product is blown through several hundred feet of 4" tubing, either into attics or into wall cavities. For wall spray, a nozzle with spray tips at the end of the tubing is used. Water through a separate water line to the nozzle creates an atomized mist through which the insulation is blown. The moisture picked up in this process enables the insulation to stick in place in the open stud cavity. A stud-scrubber is then used to clean the studs and to even the surface of the insulation with the face of the studs. Normally, the sprayed wall can be sheet- rocked the next day.
National Fiber's Cellulose Insulation Products
Our 100% newsprint provides long, inter-locking fibers for superior loft and insulation. These long fibers are impregnated with our special blend of fire retardant chemicals, and our optimum density provides coverage of 50 square feet per bag at R-19, which is unsurpassed by any other insulation. We inject a dust control oil into our insulation, which provides a virtually dust free product. Our insulation products are packed in 26.5 lb. bags.
Our cellulose insulation is regularly tested and monitored by R&D Services. Material on their qualifications and certification is available upon request. Ron Graves and Dave Yarbrough are the most respected authorities on testing insulation of all types in the country.
Why Bonded?
1. It's environmentally safe. Bonded Cellulose is a natural fiber made from milled newsprint coupled with
non-hazardous fire retardant. It contains no asbestos, fiberglass, formaldehyde, or mineral fibers.
2. It's lightweight. By careful selection of stock and blending of chemicals, the density is maintained at 1.4
pounds per cubic foot. This allows for greater thermal protection at less weight.
3. Long flexible fibers. This allows Bonded Cellulose fibers to be blown easily into small cavities through openings as small as 5/8 of an inch. So you can insulate thoroughly without disturbing the appearance of the home. Remember that proper air and insulation rate settings on the blowing machine are important when insulating sidewalls.
4. High R-value. Insulation has but one job to do: slow down the flow of heat from one area to another. The ability of a material to do this is measured in R-values. The greater the R-value, the better the insulation. Bonded Cellulose Insulation is 3.8 R-value, higher than most types of insulating materials. It gives you greater protection with less material.
5. It's non-corrosive. Bonded Cellulose Insulation will not adversely affect any known type of building material.
6. It helps dissipate moisture. The millions of microscopic air cells in Bonded's insulation helps dissipate moisture by evaporation before it can collect to damage framing members, plaster or paint.
7. It won't settle. When properly installed, cellulose insulation will not settle in sidewalls.
NOTE: Do not install next to recessed light fixtures. Do not use for temperatures over 194°F /90°C. Do not cover attic vents. Keep insulation 3" from chimney flues.
