Abstract
A multi-layer insulation product which achieves low emissivity values by using at least one layer of metallic foil. The metallic foil (25, 29) is used at exterior locations of the insulation product by way of novel strengthening means positioned below said metallic foil. A central layer of foamed material (21) adds to the insulative effect. The strengthening features of the invention allow use of the insulation product on exterior locations which has not heretofore been possible in the art.
