Low-E Window Coating
What is Low-E?
Low-E is the clear low-emissive 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.
How Low-E works:
The Low-E allows most natural light to enter freely but reflects
a significant portion of 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.
