Cel-Pak
National Fiber's Cel-Pak is a high quality, all-borate, loose-fill cellulose insulation for use in blowing caps in attics and in dense-packing wall and ceiling cavities, either for retro-fit or new construction applications.
Cel-Pak is composed of:
- Over-issue newsprint (yesterday's unsold newspapers), which is the cleanest and highest quality paper available
- Boric Acid, a highly effective fire retardant
- A small amount of a light white mineral oil for dust control
Our Cel-Pak cellulose insulation complies fully with CPSP standard HH-I-515E; 16CFR 1209; and ASTM C-739. It is made from cellulosic fibers derived primarily from recycled, over-issue newsprint. This, along with hand sorting, virtually eliminates plastic and trash from our insulation, making it cleaner, less dusty, and more installer friendly. None of these fibers are sourced directly from wood.
In all applications, bags of cellulose insulation are placed in an industrial-quality blowing machine. The product is then blown through several hundred feet of 2" to 3" hose, either into attics or dense-packed into wall cavities. In new construction applications, the wall cavity is formed by stretching and stapling synthetic webbing or poly sheeting across the open-faced studs. A slit is made in the webbing for the hose, the hose is inserted, and the cavity can be viewed as it is filled with dense-packed cellulose insulation. The sheet-rock is then installed on the studs over the membrane. In retrofit applications, the insulation is blown through holes drilled in either the inside sheet-rock or the outside plywood cladding, using a tube to reach the ends of the cavities.
All of the physical characteristics of our Cel-Pak cellulose insulation, including fire retardancy, are tested and monitored on a regular and random basis by R&D Services, a certified third party testing service, and the Cel-Pak bag is labeled with these test results.
