In recent years, in order to protect the global environment, it has been required to establish chlorofluorocarbon-free or energy-saving technologies as technologies for protecting the ozone layer and preventing global warming. Vacuum insulation is attracting attention, but it is not without its drawbacks and has weaknesses such as being unable to cut or drill holes. Also, heat bridge from the surroundings cannot be prevented.
To increase the thermal insulation performance, simply double the thickness of the thermal insulation to double the performance, but the thermal insulation width increases to double the cost and thickness, so simply increase the thickness. I can't.
In order to improve the performance without increasing the insulation thickness, a further high-performance insulation is required.
Insulation that can reduce thickness and cost is ideal. If it is possible to improve the heat insulation performance by processing the same heat insulating material, it is not necessary to make a new selection and it is easy to select the performance improvement with the same material.

Develop high-performance insulation that has performance comparable to vacuum insulation and can cut and drill holes anywhere.

Ideally, the insulation is thin, high performance, and can be cut, pasted and drilled anywhere. This insulation has the same performance as the vacuum insulation, and since it is not vacuum-packed, it can be cut anywhere, and holes can be drilled anywhere, so it doesn't matter the working environment.

Here, foamed resin (0.5 to 5 mm is laminated on an aluminum sheet (6 to 100 microns). An ultra-thin heat insulating material is made and laminated to produce a multilayer heat insulating material.

The ultra-thin heat insulating materials manufactured above (aluminum 6 microns, foamed resin 0.5 mm) are stacked in a multi-stage manner with a total of 0.506 mm of heat insulating materials depending on application and required heat insulating performance. For example, if 20 sheets are required, if 20 sheets are stacked, a multistage heat insulating material of 0.506 * 20 sheets of 10.12 mm is completed.
It can also be changed according to the heat insulation condition for obtaining the thickness of the constituent members.
This is comparable to vacuum insulation.

Similarly, if an object of about 100 mm is required, 0.506 * 100 sheets may be laminated.

Also, depending on the required heat insulation performance, aluminum 10 micron + foamed resin 5 mm may be laminated 10 layers, in which case the thickness is (0.01 + 5) * 10 sheets = 50.1 mm multi-stage high-performance insulation Complete.

The same performance can be achieved by replacing the foamed resin with glass wool / board.
In this case, the manufacturing unit price can be selected by changing the material.

Thus, it is a high-performance heat insulating material that can easily cope with the required performance, cost, and thickness.
From the viewpoint of strength, aluminum foil may be welded using a laminate of PE films (about 2 microns).

An ultra-thin heat insulating material of 1.006 mm can be provided at a minimum, and desired heat insulating performance can be selected by thickness and number of layers. As a result of improving the desired heat insulating performance, it can be applied as various heat insulating materials.

  Cross section of laminated aluminum and foamed resin.   This is a multistage heat insulating material in which the heat insulating materials shown in Fig. 1 are laminated.
