to prove effectiveness of dry cellulose. Brian Riessen is an Iowa-based
insulation specialist who installs up to 100 jobs per year. For
the last decade, all of those projects were insulated with dry cellulose.
"I guess what first attracted me to it is that it's a recycled
product," he recalls. "I had been with a weatherization
program and saw what a great value it added to old homes, so doing
it to new construction was a natural for me," he recalled.
"Now ParPAC is what we use in everything we do."
Among Riessen's current projects is a passive solar demonstration
home now under construction in Christmas Cove, Maine. The south
facing structure has been engineered for an air infiltration ratio
of less than .9 air changes per hour. The building's shell will
be insulated with ParPAC (90 percent recycled content) with a goal
of reducing the energy used in heating and air conditioning by 50

up for reuse, the wall is immediately ready for sheetrock.
