ABOUT

CleanFiber, formerly known as UltraCell Insulation, makes high performance building insulation from recycled corrugated cardboard. Their competitors make cellulose insulation from recycled newsprint, but are facing rapidly dwindling supplies as readers turn online. In contrast, their unique patented and proven process allows them to manufacture a superior product from corrugated cardboard at a lower cost than conventional cellulose insulation.
