WE'RE INSTALLERS, ENGINEERS, SCIENTISTS AND ENTREPRENEURS (AND WE LOVE BEING THE UNDERDOG). CleanFiberâ„¢ (formerly Ultracell Insulation) was conceived by veteran cellulose installers in Maine, who saw dwindling supplies of newsprint as a threat to their livelihood. So they did something about it. After creating a strong team, working like dogs for more than 9 years to perfect the process, and raising millions of dollars in investment, we're excited to be launching commercial production of certified CleanFiber in 2018. We expect our state-of-the-art production facility in Buffalo to produce upwards of 3 million bags annually. And those high production volumes will allow us to offer our all-borate product at extremely competitive pricing.
