The reason why the shade of a corrugated roof is hot and the shade of a tree is cool, as well as the principles of heat, will be explained! Even though the wind passes through and the temperature remains unchanged, why is the shade of a corrugated roof hot while the shade of a tree is cool? The answer lies in "radiant heat." Radiant heat refers to electromagnetic waves such as far-infrared rays. When you have a bonfire in a drum, your body warms up even though the wind is blowing. In this way, radiant heat moves from the hotter object (the drum) to the cooler object (the human body), transmitting heat regardless of the air. 【Reasons why the shade of a corrugated roof is hot】 ■ Temperature in summer: 70°C to 80°C ■ Human skin temperature: about 32°C to 33°C ■ Radiant heat from the corrugated roof is directed towards the human body ■ Even in the same shade, the perceived temperature can vary greatly depending on the presence of radiant heat ➙ The Sky Sheet (heat-insulating sheet) used in the Sky Method cuts 97% of radiant heat from the sun.

A single installation can simultaneously address heat insulation and prevent rain leaks! Introducing a new method that solves the challenges of heat-reflective coatings. The "Sky Method" involves installing a sky sheet made of aluminum foil, which excels in reflecting radiant heat. It provides uniform heat insulation effects regardless of the skill level of the workers or the weather conditions during installation. Additionally, it effectively prevents rain leaks specific to corrugated roofs, making it a groundbreaking method that addresses both heat insulation and rain leak prevention in one installation. 【Features of the Installation】 ■ A method that installs a sky sheet made of aluminum foil, which excels in reflecting radiant heat. ■ Provides uniform heat insulation effects regardless of the skill level of the workers or the weather conditions during installation. ■ Effectively prevents rain leaks specific to corrugated roofs. ■ Addresses both heat insulation and rain leak prevention in one installation.

Sky Method Energy-Saving Effect The maximum temperature difference measured from the experimental results is approximately 11°C. By alleviating summer heat, it can be used to save on air conditioning costs, prevent deterioration of stock products, and improve the working environment. [Effects of Implementation] ■ Savings on air conditioning costs ■ Prevention of stock product deterioration ■ Improvement of the working environment Reliable quality proven by experiments Indoor temperature measurement tests by Professor Nakayama of Shizuoka University Faculty of Engineering on the presence or absence of thermal barriers. [Experimental Results] ■ Maximum energy-saving effect of approximately -11°C ■ Attic temperature decreased by "up to 9°C" ■ Temperature of warm air mass in the attic decreased by "approximately 4°C" ■ Achieved up to approximately 30% reduction in electricity costs ■ Patent obtained (Patent No. 6598337)

Sky Method that Withstands Typhoon Winds Tests were conducted at the Japan Building Disaster Prevention Association to determine whether the Sky Sheet would be blown away by strong winds from a typhoon. The tests revealed that even with wind speeds of 40 meters per second at a height of 16 meters, the Sky Sheet did not get blown away. [About the Double-Sided Tape Used in the Sky Method] The double-sided tape used in the Sky Method is a highly durable tape that excels in holding power and water resistance, suitable for outdoor use with a temperature range of -10°C to 90°C.

With the Sky Method, you can walk barefoot! The roof, which exceeds 60 degrees due to the summer sun, has cooled down enough to walk barefoot.
