The hot air cycle is a complex problem, with three main modes of heat conduction: conduction, convection, and radiation.
- Through radiation and conduction, hot air passes through the roof and walls and enters the room. In summer, the roof becomes the center of heat, and the heat absorbed and stored by the insulation material remains on the roof. After several hours of sunset, air conditioning is still needed to remove the heat received by the roof to keep the room cool.
The vast majority of heat is transmitted by radiation, and the roof and walls absorb a large amount of radiation heat and transmit it to the interior, generating indoor high temperatures. Therefore, how to reduce the heat absorbed by roofs and walls is the most effective insulation method. PARSEC® insulation foil is due to its high reflectivity of infrared rays, which can effectively block infrared rays and prevent thermal radiation, thereby minimizing energy consumption.
