Summary:The inventive method of preparing an insulation article comprises providing a sealed first container comprising aerogel particles under a first air pressure that is less than atmospheric pressure. The unrestrained volume of the aerogel particles at the first air pressure is less than the unrestrained volume of the aerogel particles under a second air pressure that is greater than the first air pressure. The sealed first container then is placed within a second container, and the sealed first container is breached to equalize the air pressure between the first and second containers at the second air pressure and to increase the volume of the aerogel particles, thereby forming the insulation article.
