Low-e glass is created by depositing a microscopically thin, transparent metal ormetallic oxide layer on the glass. When the interior heat energy tries to escape to thecolder outside during the winter, the low-e coating reflects the heat back to the inside, reducing the radiant heat loss through the glass. The reverse happens during thesummer. Advantages: Energy Efficiency, reduces heat loss by up to 50% Long term cost saving, decreases heating expenses Does not reduce natural daylight or transparency Ensures maximum benefit from solar heat Protects against UV radiation by over 68% reducing aging and fading effects
