ABSTRACT:
Thermal insulation comprised of fiberglass boards or batts having relatively small diameter fiberglass fibers either bound or unbound is wound about the lading container pressure vessel of a tank truck, trailer or rail car. As the insulation is wound about a longitudinal section of the vessel, the insulation is squeezed from its free height to a lesser height to increase the density of the insulation and also permit passage of the outer jacket. The squeezing is preferably accomplished by wrapping each layer of insulation with a continuous wire mesh. The tension is maintained with the use of a long rod intertwined in the wire mesh, which rod is withdrawn after a section of the outer jacket is over a section of the vessel thereby permitting the insulation to expand and substantially fill the void between the vessel and outer jacket.
