ABSTRACT:
Particulate insulation materials such as vermiculite, perlite, or cellulose are packaged in sturdy resinous bags 10 sealed at each end and then positioned directly over a body to be insulated. The resin bags contain the insulation particles, hold them in place, and keep them dry; and the particles can be spread into an even barrier layer within the bags, which protect the particles during use. Bags 10 can be laid side by side over a surface, above and below a pipe, and concentrically surrounding a pipe. Bagged insulation particles are especially suitable for underground insulation where backfilled earth applies uniform pressure helping to hold the bags and insulation particles in place indefinitely.
