Thermal insulation system

摘要: 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 contain the particles, hold them place, keep dry; particles can spread into an even barrier layer within bags, which protect during use. Bags laid side by surface, above below pipe, concentrically surrounding pipe. Bagged especially suitable for underground where backfilled earth applies uniform pressure helping place indefinitely.
