New Cellulose Manufacturer Set for a 2018 Launch

The Buffalo-based company will help fill the void left by the closure of National Fiber

Posted on Feb 23 2017 by Scott Gibson

Builders in the Northeast who have missed the friendly voice of Bill Hulstrunk and cellulose from National Fiber, the Massachusetts-based firm he worked for, can look forward to the launch of a new company and a fresh source of cellulose by next year.

Hulstrunk, the technical director at the now-shuttered National Fiber plant in Belchertown, Massachusetts, has joined a new company called UltraCell, which is building a pilot plant in Buffalo, New York, and hopes to open a larger plant and begin selling the insulation in 2018.

Do you want to keep your heating costs from going through the roof? It’s easy: Keep your heat from going through the roof. Saving money on heating-fuel costs is a lot simpler than negotiating with OPEC or your local utility. On a recent upgrade in the attic of a 1950s-era house (one of two projects shown here), I air-sealed and spread a 12-in.- deep layer of cellulose throughout 1500 sq. ft. of space in about a day.
