Breakthroughs in Material Science

The cellulose insulation industry has seen little innovation in many years. Our founders – veteran installers, process engineers, and scientists from the University of Maine Process Development Center – saw a path to produce a dramatically better cellulose insulation product through application of Material Science.

We began by looking at cellulose fiber. The industry currently relies on recycled newspaper and paper trash as its fiber feedstock. Upon examination of the fiber, and upon observation that single-stream recycling of newspaper and paper trash often leaves contaminants and inclusions with the fiber, we looked to find a better source of fiber and a process to make it work.


Our quest brought us to recycled corrugated cardboard, and we arrived at a “wet” process that blends fiber from pulped recycled cardboard with fiber from other clean fiber feedstocks. The result is an extraordinarily clean and robust fiber, inherently better-suited for producing high-quality cellulose insulation than fiber from shredded newspaper and mixed paper recycling streams.

We then turned our attention to fire retardation, and saw that the industry currently employs a “dry” process to mix fire retardant

chemicals, in powder form, with shredded newspaper and other mixed recycled papers. This leaves them vulnerable to contamination by foreign materials (such as plastics and twine) and with a dusty product.

Our patented “wet” process, and our Celluborate® fire retardant formulation, impregnates the retardants uniformly across the fibers and directly into the fiber walls, resulting in reduced potential to produce airborne dust, and much-improved material efficiency. Our reduced chemical loading contributes to achieving higher R-values and lower settled density, while meeting critical certification requirements for fire retardancy.

Finally, we gave attention to employ the latest, state-of-the-art fiberization technologies to maintain fiber resiliency and produce individually-separated fibers without excessive fines.

We hold multiple issued and pending patents for our technology, and we look forward to coming to market with a very high-quality product in 2018.
