Airflow accounts for 98% of moisture movement. Since fiberglass
is not an air barrier it provides no protection against
moisture and mold. Cellulose is so effective at blocking
airflow and managing moisture that you don't need a poly
vapor barrier.
While the air-blocking capability of high-density cellulose
insulation prevents moisture flow, the borates in our
specially treated NuWool Wallseal cellulose insulation
inhibits mold and fungus growth from any condensation.
Our cellulose insulation wicks moisture away from the
surrounding building components and carries it to drier
areas.
