Abstract: A method for packaging and installing high performance insulation of a loose, granular, moisture-resistant nature, suitable for providing insulation in walls, ceilings, or other cavities in traditional buildings, cabinets or other structures requiring thermal or sound insulation, in a practical, easy to manage, modular fashion. The method provides for the packaging of insulation material to be contained in an air-tight but moisture permeable material that traps the particulates but not moisture vapor. The insulation material may also be blended with other materials to adjust the product's resistance to thermal or sound conductivity, cost, and in order to prevent leakage in the event of puncture.
