Thermal insulation tank base solutions for tanks operating at cryogenic temperatures.

Our tank base systems provide adequate compressive strength to carry the tank and its contents and at the same time limit possible heat transfer to protect the structural material against extreme temperatures.

Since the 1960's, tank builders worldwide have trusted FOAMGLAS® insulation as a core component in tank base insulation systems. Today, thousands of tanks are supported by FOAMGLAS® insulation systems.

In an application for a cryogenic tank base, lack of compressive strength can result in an unacceptable settlement which may result in a loss of thermal insulating capacity, ground heaving and foundations being brought to temperatures that could result in major failures. In the case of uneven subsidence, rupture in the tank’s steel bottom could result in a subsequent loss of product.

A dedicated tank base insulation under your cryogenic tank can help avoid excessive heat transfer, which could cause the support structure to freeze and create mechanical problems. It can also help protect the structural material against extreme temperatures. This requirement is important with liquefied gases, which are stored at such low temperatures that normal containment products can become brittle in direct contact.

FOAMGLAS® insulation has a long and successful track record of insulating above ground cryogenic storage tanks in facilities worldwide. We offer High Load Bearing (FOAMGLAS® HLB insulation) solutions for the base insulation of various types of cryogenic tanks (i.e. LPG, LNG, LOX, and LNI).

In fact, FOAMGLAS® HLB insulation is a core component of over 90% of the world's Liquified Natural Gas tank base insulation systems, a critical application requiring high load bearing capabilities and thermal insulation properties.

Our HLB types are specially produced for tank base insulation applications and subjected to very stringent quality controls, corresponding to the risk associated with this application.

HLB Tank

Typical configuration for Cryogenic Tank Base Applications:

  • Multi-layer system of FOAMGLAS® HLB insulation.
  • PITTCOURSE™ DPC interleaving membrane or other appropriate interleaving for the application temperature range.
