Performance, cost, and ease of installation.
The "obstacle" that was preventing ideal heat management.

The extreme heat in factories and warehouses during the summer months poses a serious threat to the safety and productivity of workers.
On the other hand, conventional heat-shielding measures have faced significant obstacles due to high construction costs and maintenance burdens.

Such challenges related to "heat",
issues like these?

Task
01 Illustration illustrating the deterioration of working conditions

Deterioration of working conditions

"I can't stand the heat in warehouses and factories..."
Rising temperatures can lead to decreased employee performance and increased risk of heatstroke.

Task
02 Illustration illustrating rising costs

Rising costs

"The electricity bill for the air conditioning in our office has skyrocketed…"
Electricity costs have increased due to excessive use of air conditioning.

Task
03 Illustration showing equipment trouble

Equipment trouble

"The outdoor electrical equipment suddenly broke down..."
Deterioration and shutdown of control panels and infrastructure due to thermal runaway.

Apply it to roofs, walls, windows, and fixtures to reduce heat. That is a heat-shielding cooling film.

With its "easy installation," anyone can apply it anywhere—just stick it on.

Easy application: Thanks to a special adhesive,
The installation was completed quickly without leaving any wrinkles.

Step 1-1
Sprinkle water on the surface to be worked on and clean it with a scraper.

Cleaning (for windows)
Sprinkle water on the surface to be worked on and clean it with a scraper.

Step 1-2
Clean the work surface with high-pressure water, or clean the wiper/brush with water.

Cleaning (for painted surfaces)
Clean the work surface with high-pressure water, or clean the wiper/brush with water.

Step 2
Remove the protective film and apply the application liquid to the adhesive surface.

Remove the protective film,
Apply the application liquid to the adhesive surface.
(*Water + approximately 0.1% neutral detergent)

Step 3
Apply the application solution to the surface, attach the film, and adjust its position.

Apply the application solution to the surface to be treated.
Apply the film and adjust its position.

Step 4
Apply the film

Apply the application solution to the film surface,Use a squeegee to remove water from between the film and the application surface.

Step 5
Cut the excess portion of the film to the correct dimensions.

Cut the excess portion of the film to the correct dimensions.
