1 : Heat conduction prevention by microfiber with advanced technology.
Microfiber with the diameter of several microns shaped in the form of cotton is used for the center part of the heatinsulation sheet. These entangle in a net-like shape with high density and it confines an air as air bubble inside of eachfiber by a patented technology of burst fiber method. Front surface is wrapped in a PE foam sheet with low thermal
conductivity, furthermore, keeping the dead air prevents more heat conductance.

2 : Easy opening and closing operation using a curtain rail.
Not only putting it on a product or a cart, it can be also used as a partition by fitting it to the curtain rail because the sheet
is light. Single sliding or double sliding handle is used together, opening and closing operation can be easily done. Inorder to increase the sealing effect, a gap blocking sheet can be attached to the upper part of curtain rail. When thecurtain is not used, it can be tied to one side with a same fabric belt.

Thermal transmittance calculation of Heat insulation sheet
Thermal transmittance ：Ｋ ＝2.17Kcａｌ/m2 ・ｈ・℃
Thermal conductivityλ1 ： 0.05Ｋｃａｌ／ｍ・ｈ・℃
Heat transfer coefficient of outer surfaceλ2 ： 5Ｋｃａｌ／ｍ・ｈ・℃
Heat transfer coefficient of inner surface λ3 ： 7Ｋｃａｌ／ｍ・ｈ・℃
Sheet thickness ｔ： 0.003ｍ (average)

K =1
１/λ2＋ｔ/λ1＋1/λ3(in a windless state)(in a gentle wind state)＊Attention①Thermal transmittance of heat insulation sheet is greatly influenced by inner/outer wind velocity of the partition material.
The test calculation mentioned above was in the state of one side was windless, the other side was gentle wind.
When both sides were windless, K=2.17Kcａｌ/m２ ・ｈ・℃
When both sides were gentle wind, K=2.89Kcａｌ/m２ ・ｈ・℃
②The thickness of heat insulation sheet varies. It is thin at the stitching part in which is about 1mm and the thickest part is 6mm.
Thermal transmittance changes depending on this. Calculated average value to set was 3mm.
Thermal transmittance of the stitching part K=2.44Ｋｃａｌ／ｍ・ｈ・℃ （When both sides were windless）
Thermal transmittance of 6mm thickness part K=1.93Ｋｃａｌ／ｍ・ｈ・℃ （When both sides were windless）③Thermal transmittance at the stitching part is big, therefore dew condensation easily occur on the front surface.
④Dew condensation on the front surface needs attention when the temperature difference is large. Dew condensation is liable to occur on a high temperature surface.
In order to prevent occurrence of dew condensation, make less humid, or exposure to wind on a high temperature surface can reduce the development of dewcondensation. On the contrary, exposure to wind on a low temperature surface and the high temperature side is windless, dew condensation is liable to occur.

Heat insulation sheet in which reasonably combines 2 kinds of thermal insulation material,
an aluminum film and an air layer.
It cuts off ultraviolet ray and proposes that creating an environment in which reduces
the development of dew condensation, even when the temperature difference is 15℃.
