Does All Tech Insulation Cellulose System attract moisture?
the All Tech Insulation Cellulose System does not attract moisture, but the All Tech Insulation Cellulose System fibers have a natural ability to handle moisture. Moisture vapor in the air is absorbed and released depending upon the relative humidity of the surrounding air. the All Tech Insulation Cellulose System fibers retain a natural moisture level between 5-8% by weight, and as much as 15% has no effect on the thermal insulating characteristics. Many authorities believe the demonstrated ability of All Tech Insulation Cellulose System to control moisture transport by eliminating air infiltration makes vapor barriers unnecessary when All Tech Insulation Cellulose System is installed. All Tech Insulation does not recommend the use of a vapor barrier, as they add virtually nothing to the performance of the All Tech Insulation Cellulose System.
