Summer 夏季
Radiation is electromagnetic waves which directly transport heat energy through space. Through radiation, solar gain from sunlight shining through glass windows can send heat into the room.
SEAG Film is specially designed to provide insulation by changing the emissivity of the surface where it is applied. All materials have emissivity ranging from 0 to 1 and a lower value indicates a surface with a low level of radiation. Glass exhibits high emissivity at 0.95. SEAG’s radiation control technology works by lowering the surface emissivity to 0.049 or 1/18 (laboratory test preformed by Saitama Industrial Technology Centre), lessening its ability to radiate heat without perceptible reduction in visible light.
輻射是電磁波，它直接將熱能傳輸通過空間。 通過輻射，陽光透過玻璃窗獲得的太陽能可以將熱量傳遞到房間中。
SEAG膜經過專門設計，可通過改變其應用表面的發射率來提供絕緣。 所有材料的發射率都在0到1的範圍內，較低的值表示輻射水平較低的表面。 玻璃顯示出0.95的高發射率。 SEAG的輻射控制技術的工作原理是將表面發射率降低至0.049或1/18（Technology玉工業技術中心進行的實驗室測試），從而降低了其輻射熱量的能力，而看不到可見光的減少。
Winter 冬季
Convection is the transfer of heat in fluid or air, caused by the movement of the
heated air or fluid itself.
During winter the inside of the window is warmer than the outside on average. The window will act as a medium for the transfer of heat from the inside of the property to the outside. The window absorbs heat from the air inside that is closest to the window, that colder air then drops to be replaced by new warmer air, and so the process repeats until the inside air is the same temperature as the outside! Basically, the greater the temperature difference between the inside and outside of the window, the easier it is for air to move and the greater losses occur due to convection.
SEAG Film breaks the link between heat transfer through the window. It resists and minimizes air movement and effectively reduces heat loss due to convection.
對流是由加熱的空氣或流體本身的運動引起的流體或空氣中的熱傳遞。
在冬季，窗戶的內部平均比外面的溫暖。 窗戶將充當從房屋內部向外部傳遞熱量的媒介。 窗戶從最靠近窗戶的內部空氣中吸收熱量，然後較冷的空氣滴落而被新的較溫暖的空氣取代，因此重複此過程，直到內部空氣的溫度與外部溫度相同！ 基本上，窗戶內側和外側之間的溫度差越大，空氣越容易移動，並且由於對流而產生的損失也越大。
SEAG Film打破了通過窗戶傳熱之間的聯繫。 它可以抵抗並最大程度地減少空氣流動，並有效地減少由於對流引起的熱損失。
