Note: Hanson R-16 foam outdoor tank insulation is
an effective alternative to metal jacketed tanks at about 70% saving
for the same R. Value. Any minor shipping damage can easily be repaired
in the field with no effect on performance or durability. As the foam
is closed-cell, and impermeable by water, any pinholes noticed in the
topcoat are cosmetic and do not affect the durability of the product.
Due to the characteristics of the product, the actual expanded thickness of the
insulation at R16 can be 3" or more.
Before system startup and periodically during service, the topcoat should be examined and repaired if necessary. We also recommend inorganic zinc tank primer at extra cost.
Although we offer this insulation system for outdoor service only, with the addition of a thermal barrier by the installer, it can be approved for indoor service in most jurisdictions.
Thermal barriers can be metal, cement, plaster or suitable proprietary materials with fire resistance properties equal to 1/2" gypsum wall board. Final approval of a thermal barrier installation is at the discretion of the local building code official.
