PAKWRAP316M

PAKWRAP316M is used to either contain heat for maintaining warmth, or to resist heat for maintaining cols. In many applications, radiation is the dominant mode of heat transfer. PAKWRAP316M foil bubble is considerably more effective than conventional insulations in reducing radiant heat transfer. PAKWRAP316M foil bubble reflects up to 97% of radiant energy in addition to resisting other types of heat transfer thus providing effective insulation.
