What is Stainless Steel
Vacuum Insulation Panel?
TIVIP
A stainless Steel Vacuum Insulation Panel (TIVIP: TIGER Vacuum Insulated Panel) is a high-performance insulating material that uses stainless steel foil to create a vacuum inside the panel, resulting in very low heat conduction.
Compared with conventional insulation materials, it provides high thermal insulation effect even with very thin layers. These properties have attracted attention in various fields where energy conservation and efficient use of space are important.
Mechanism of Stainless Steel Vacuum Insulation Panel
This material is made by creating a vacuum inside a double-layered stainless steel foil to enhance thermal insulation performance. In addition, a core material is placed inside to seal it in order to maintain its shape.

Key Features
High thermal insulation
We apply vacuum insulation technology used in vacuum-insulated bottles. It has a very high thermal insulation effect compared with conventional insulation materials.
Long service life
Using the same material as vacuum-insulated bottles, stainless steel, and the sealing technology we have developed, the vacuum can be maintained for more than 30 years, giving it a long service life.

Non-flammability
Unlike ordinary vacuum insulation materials, this material is made of stainless steel, making it nonflammable and highly safe.

Realized with High thermal insulation, Long service life, and Nonflammability
Because the interior is a vacuum, the heat conductivity is less than 0.0025 W/m・K*1, which is approximately 10 to 25 times higher than that of conventional heat insulators.
Furthermore, by using stainless materials and applying the vacuum insulation technology for vacuum bottles to create a panel, we made it possible to maintain nonflammability and high thermal insulation properties over a long period of time, something that was not possible with conventional vacuum insulation materials.
This has enabled us to maintain vacuum insulation for a long period of time (more than 30 years)*2, thereby achieving safety through its long service life and nonflammability.

Actual thickness may vary depending on product and usage conditions.
Realized with Surprising Thinness
Equivalent heat insulation effect can be obtained with about 1/10th the thinness of urethane foam*3
- *Thermal resistance R=0.01/0.0025=4.00 m2K/W for a prototype of TIVIP with a thickness of 10 mm and size of over 440 mm square, Thermal resistance R=0.1/0.024=4.16 m2K/W for rigid polyurethane foam of a thickness of 100 mm and size of over 440 mm square

Benefits of Stainless Steel
Vacuum Insulation Panel
Benefit
01
Reduction in energy costs
Utilizing stainless steel vacuum insulation panel for transport refrigeration containers and building materials can reduce the use of electric energy required to maintain temperature, thereby contributing to CO2 reduction and lower running costs.
Benefit
02
Reduction in life cycle costs
The vacuum can be maintained for more than 30 years and has a long life, significantly reduces the frequency of replacement of insulation materials and the total cost (life cycle cost) over the service life of the shipping container and building.

Benefit
03
High safety
Highly nonflammable, it reduces the risk of fire, thus increasing the safety of the product and the building as a whole.
Benefit
04
Improved cooling effect
Even with the same thickness as conventional insulation, higher insulation is possible, resulting in improved heat and cold retention.
Benefit
05
Recyclable
Tiger Corporation started setting up collection boxes to collect used stainless-steel bottles for personal use in October 2021.
We work on recycling stainless-steel bottles.
