75% Visible light transmittance/ 80% IR Cut / 99% UV Cut

Visible light transmittance is the value to evaluate the transparency after the glass coating. CTO= Hyper-SP and
ITO =IRUV SP have high transparency. It’s ideal for the large window glass such as showrooms, observation
deck and restaurants without unevenness and coating spots.

Case Studies / IRUV CUT COAT

◆Point ②

The wavelength range of near infrared, represents the transmittance of solar direct heat, this is thereference value to evaluate the thermal barrier performance. The lower the infrared transmittance thatwill be a thermal barrier performance is high, CTO= Hyper-SP has higher thermal barrier performance than
ATO and ITO. Window glass surface of the building that does not work air conditioning at summer because ofsun heat, MTO is the best product to save the air condition load.近
◆Point ③

The wavelength range of far infrared rays indicates indoor heating heat. If the room is cold when the heatescapes from the window in the winter, the high far-infrared cut rate prevent to escape the heat from thewindow. If only cold area, each ATO, ITO, and CTO is ideal for the cold of winter measures.

Result of the temperature measurement, maximum15 degrees cut the direct heat of the windowIn particular, the hottest time of day is significantly cut, down the air-conditioning load

Example of energy saving calculation
Result of the temperature measurement, the temperature difference of the direct heat at the window was 8 ℃(maximum) in comparison with the uncoated glass (Low-E glass) Reduction rate of the air conditioning costs was
20 percent, so recovery of the initial investment simulated in 2.03 years. Because there was high electricity prices
and low applicator cost. For 10 years coating guarantees, we can expect significant cost savings of 20% to 30%
more than eight years is.
