Low-e Glass Low-E glass improves thermal performance and reduces solar heat gain in residential and commercial glazing applications compared to standard uncoated glass units. The 'E' in low-E refers to emissivity. Emissivity is a measure of a material's ability to radiate energy. A material with 'low' emissivity
absorbs and radiates infrared energy poorly which is the key factor in reducing heat transfer. The Low-E allows most natural light to enter freely, but reflects a significant portion of long and short wave heat energy. In the summer, long-wave heat energy radiating from objects is reflected back outside, lowering cooling cost. In winter, internal long-wave heat energy is reflected back inside, lowering heating cost.
Featrues:
Low-E is the clear low-emissivity coating on one side of the glass that is microscopically - thin and has optically transparent layers of silver sandwiched between layers of metal oxide coatings. This specific process is known as "sputter coating" and is also referred to as softcoat. Low-E filters the suns energy in the summer and reduces heat loss in the winter. Low-E lets in visible sunlight while blocking infrared and reducing ultraviolet solar energy that fades carpet and furniture. Applications:
Low-E glass has been used for nearly two decades. Until now, Low-E has been a product usually recommended for cold climates. With our introduction of SunCoat Low-E we can use this product in the heat or in the cold climate.
