Quality Product

National Fiber makes the highest quality, most cost-effective insulation of any type in the Northeastern U.S.  Made from over-issue news (yesterday's unsold newspapers), which is the cleanest and best quality newsprint available, National Fiber's insulation is consistent, clean, and free of foreign material. National Fiber then goes one step further by hand sorting the newspapers to remove magazines and glossy inserts, the fibers of which are short and clay-coated. Unlike some manufacturers, National Fiber does not buy from trash recyclers and no trash enters the plant, so no trash is found in its products. National Fiber's selection of newsprint provides long, inter-locking fibers for superior loft and insulation. These long fibers are porous and are easily infused with highly refined borates. Borates are naturally occurring minerals that provide National Fiber's cellulose insulation with it's fire retardant properties, as well as resistance to mold, insects and rodents.

Industry Regulations: The physical characteristics of cellulose insulation are governed by the Consumer Product Safety Commission, the Code of Federal Regulations, and the American Society of Testing and Measurements. There are two very stringent fire tests involved in the production of cellulose insulation. One determines the product's resistance to smoldering combustion, and the second determines the product's resistance to the propagation of flame along the surface of the cellulose insulation. National Fiber's cellulose insulations have also passed the ASTM E-84 fire test, with a flame spread index of 20 and a smoke developed index of 0, making them Class 1 building materials. All of the physical characteristics of National Fiber's cellulose insulations, including fire retardancy, are tested and monitored on a regular and random basis by R&D Services and U.L. certified third party testing services, as indicated on the label.

Certified Installation: The proper installation of cellulose insulation is key to ensuring its performance. National Fiber plays an active role in monitoring the equipment and performance of installing contractors by offering extensive training, as well as field and technical support after the sale. In all applications, bags of cellulose insulation are placed in an industrial-quality blowing machine. The product is blown through several hundred feet of 3" tubing, either into attics or dense-packed into wall cavities. In retrofit situations, the insulation can be blown through holes drilled in either the interior wall covering or the exterior sheathing, using a tube to reach the ends of the cavities. In new construction situations, the wall cavity can be formed by stretching and stapling synthetic webbing or sheeting across open-faced studs. A slit is made in the webbing for the hose, and the cavity can been viewed as it is filled with dense-packed cellulose insulation. The sheetrock is then installed on the studs over the membrane.
