CleanFiber is a construction manufacturing company that makes building insulation from recycled corrugated cardboard. The company describes its cellulose insulation as the purest, cleanest, best-performing, that gives low dust (because they infuse an all-borate, liquid fire retardant directly into the fiber walls). Besides the proprietary wet separation and infusion process floats off contaminants. CleanFiber's production facility in Buffalo is currently ramping up and will produce over 3 million bags of insulation annually. These high production volumes allow the comapny to offer the product at competitive pricing.
