The "Premium Wooden Fence," born from the Safe and Secure Fence Development Research Group at Waseda University Takaguchi Laboratory, contributes to the revitalization of artificial forests and the realization of a low-carbon society by using domestically produced cedar! Its low thermal mass allows it to adapt to warming environments. The high-durability steel frame employs "ZAM," a highly corrosion-resistant steel plate, achieving four times the corrosion resistance of hot-dip galvanized steel plates. Experts conduct structural calculations to confirm high safety standards. Manufacturing takes place in a factory, and by creating panels that can be handled by people, installation can be completed in narrow spaces where heavy machinery cannot enter, resulting in shorter construction periods. Additionally, the domestically produced cedar panels can be replaced individually in case of damage or deterioration, allowing for long-lasting aesthetics. If you have any questions or requests regarding the "Premium Wooden Fence," please feel free to contact us.

● Powerful W Blind Effect of Reflection & Heat Dissipation This heat-insulating paint achieves infrared "reflection & heat dissipation" using the world's first nanotechnology. Special ceramics, used for thermal management in high-tech devices, reflect infrared rays with their physical particle size and shape, and instantly remove heat that remains on the roof with a high thermal reflux rate, effectively cooling the building. ● Special Ceramics: A New Technology from Toyota Special ceramics possess high thermal conductivity, low thermal expansion, improved heat resistance, and many other functions, making them materials applied in cutting-edge fields for thermal management in precision devices such as electronics, electric vehicles, and medical equipment. Focusing on this "ability to dissipate heat," Ethical ProCool is the world's first paint that dramatically realizes the functionality of heat insulation through its application in building materials.

Our company is engaged in roof heat insulation painting work using the heat-insulating paint "Ethical Pro Cool." Here, we introduce a case study conducted at our Iruma Trust Center's logistics warehouse, which is approximately 3,500 m². Immediately after the application, the surface temperature decreased. Before the application, the attic temperature was between 45°C and 50°C, but after the application, it dropped to between 30°C and 35°C, a maximum reduction of 15°C. As a result, the indoor temperature (at waist height), which was previously higher than the outdoor temperature, decreased by 5°C to 7°C after the application, and it remained lower than the outdoor temperature. Significant environmental improvements were achieved by applying "Ad Green Coat." [Verification Results] <After Application> ■ Attic Temperature: Decreased by 15°C ■ Indoor Temperature: Decreased by 7°C *For more details, please refer to the PDF document or feel free to contact us.
