All types of building insulation can be considered to be “green” products because they save energy, reducing harmful carbon emissions that result from burning fossil fuels.
But Tru-Soft cellulose insulation belongs in the category of “super-green” insulation materials because it’s made from old newspapers, telephone directories and other waste paper –materials that would otherwise be dumped in landfills.
Attic insulation additives provide resistance to fire, insects and mold
Tru-Soft cellulose requires less energy to manufacture than any other type of insulation. Basically, the reclaimed paper is processed in grinding machinery that creates a fluffy, lightweight material with insulation value as high as R-4 per inch.
The insulation is then treated with a nontoxic borate solution that gives the material a Class 1 (the highest) fire safety rating, while also making it resistant to mold and insects. Cellulose is packaged in large plastic bags that are then distributed to local insulation contractors and retail distributors.
Three types of Tru-Soft cellulose insulation provide a broad range of applications
Cellulose referred to as loose-fill or blown cellulose can be applied using blowing equipment. This technique is often used to insulate attics. One worker feeds cellulose into a hopper and blower unit that supplies shredded cellulose through a long hose to another worker in the attic space.
Cellulose insulation can also be blown into wall cavities and other enclosed spaces. This application technique calls for 2-in.-diameter access holes to be drilled into the cavities, so that a small application nozzle can be inserted to inject the insulation. Because cavity-fill applications typically demand greater air pressure and a denser application, this technique is sometimes referred to as dense-pack cellulose insulation. Access holes are plugged when the job is complete.
A third application technique, called wet-spray cellulose, is designed to apply cellulose insulation into open cavities found in new construction. Water and (in some cases) a liquid adhesive or binder compound is added to the dry cellulose during the application process. The level of wetness must be controlled so that the material is sticky but not so saturated that it will settle or fall out of place.
