VIPs are thin panels made from two flexible gas barrier laminates that are welded together with a vacuum inside. Since heat cannot be conducted through a vacuum, this provides excellent insulation properties against heat or cold, but with a relatively thin overall thicknesses. Gas barrier films are used in order to maintain the inside vacuum as long as possbile, thus extending the insulation efficiency of the panel.
EVAL™ film provides outstanding barrier properties and a reliable plastic alternative to aluminium foils. Benefits include:
