Fiberlite's Cellulose Insulation has been tested as a Class I Building Material and is designed to slow the spread of flames in building fires. FTI also has an exclusive 2-Hour Fire Wall design for cellulose insulation. The "SATAC" system is approved for use as a flame resistant insulation for exposed building interiors.
