Thermal Covers

Why do shippers insulate containers and pallets?

Across all industries, moving products in shipping containers can expose the goods to severe temperature fluctuations. In many cases this can cause irreversible damage to the product resulting in lost sales, expensive insurance claims and most importantly a loss of customers faith in your product.

A prime example of where temperature variations can cause havoc is during the transportation of wine. Even minimal fluctuations can result in problems such as loss of bouquet, product oxidation and even leakage through cork dryness.

The art of winemaking is a very exact science and also an extremely competitive business. It is essential that the wine is crafted, aged and then stored to the wine-makers exact specifications. However, when it comes to transporting this wine the whole process can be undone if proper protection such as the Thermal Liner is not implemented.

Compared to the value of a 20′ or 40′ container full of wine, electronics, food etc., the Thermal Liner represents only a tiny fraction of the total cost of goods, insurance and shipping. It really is a small price to pay for peace of mind.

How does the Thermal Liner work?

The Thermal Liner is a fully woven reflective liner that is hung into a general-purpose ISO shipping container and allows for forklift loading, hand loading and slip sheet. Once loaded it is fully sealed protecting all six walls and providing a closed off temperature and humidity controlled environment for the goods within.

Without the proper protection of the Thermal Liner, cargo inside a container can be exposed to dangerous heat penetrating in three ways, conduction, radiation and convection.

Conduction occurs when the cargo makes direct contact with the container walls. Radiation or radiant heat penetrates through the container wall from the outside via infrared radiation whilst convection is the hot air circulating throughout the container.

The Thermal Liner eradicates these problems by reflecting up to 96% of the radiant heat, preventing the cargo from making direct contact with the container walls and preventing hot or cold air coming through the fully sealed liner.

The Department of Mechanical & Materials Engineering at the University of Western Australia conducted tests which showed the Thermal Liner has an emittance rate of 4% with the nearest insulation alternative only scoring around 50%. In simpler terms those using these inferior insulation alternatives are only offering their goods half the protection that the Thermal Liner offers.

Because the environment within the liner is less exposed to the fluctuations outside there is less chance the temperature inside will drop below the dew point, which can cause condensation and subsequent moisture damage.


  • Minimise temperature variations & spikes
  • Provides a radiant barrier
  • Cost effective
  • Creates an enclosed environment
  • Fitted close to but not on the container wall
  • Reduce condensation and moisture
