About radiant heat

One of the three elements of heat conduction, "radiant heat," is the key to thermal insulation!

The radiant heat from the sun that pours onto the roof of a building is divided into a small portion that directly reflects off the roofing material and the majority of heat that is absorbed. According to the laws of thermodynamics, heat moves from areas of higher temperature to lower temperature, so most of it radiates to the ceiling, where a similar heat conversion occurs, allowing it to enter the interior. Since radiant heat is what makes buildings hot, to prevent heat, it is effective to improve the performance of insulation materials, but more effectively, it is to suppress radiant heat. When a building is insulated in winter, the heat transfer between the inside and outside decreases, keeping the interior warm. When using far-infrared heating devices, radiant heat repeatedly undergoes secondary and tertiary radiation, penetrating the body and creating a sense of comfort. [Heat Transfer] - Most of the heat movement within a building is radiant heat. - It is said that radiant heat accounts for 75% of the total heat. - Conductive heat, which can be addressed with insulation materials, constitutes only 5-7% of the total, while approximately 93% is radiant heat. *For more details, please refer to the PDF document or feel free to contact us.*
