High-performance carbon-negative building insulation.

CleanFiber offers a strategy to reduce the all-in cost of homebuilding in America starting with cost effective insulation leveraging cheap corrugate waste.

Why Swingbridge Invested...

While home cellulose insulation may not be the most exciting topic, we found it exciting that CleanFiber invented a ground-breaking

solution that uses recycled corrugated (cardboard) boxes, instead of newspaper, to manufacture their insulation. To us, there was clear value in navigating the industry’s headwinds (see: the declining supply of

newspaper) while providing an opportunity to make the environment cleaner (see: the dramatic increase in Amazon boxes).
