Insulation for double wall tanks

摘要

A system of insulation for double wall tanks includes a plurality of insulation layers held on the outside of an inner wall of the double wall tank by a plurality of orthogonally arranged bands. The bands include bands oriented longitudinally of the tank and bands oriented laterally of the tank. The insulation layers include abutting units, with each unit having a facing sheet thereon. The outermost insulation layer has abutting units with overlapping facing sheets, and the insulation layers assume a quilted pattern.
