Versatile SUNGATE 600 Introduced

Posted in Glass Products, Aug. 1, 2012

SUNGATE 600 is a multifunctional glass with a durable, smooth coating that helps buildings better regulate temperatures all year.

Earlier this month, PPG Industries introduced SUNGATE 600, the newest addition to its line of passive low-emissivity (low-e) coated glasses.

Durable, Smooth Coating

SUNGATE 600 is a durable and smooth pyrolytic or “hard coat” glass with a neutral-transparent aesthetic. The SUNGATE 600 coating is 25% smoother than traditional pyrolytic coats, making it easier to clean and maintain. It is designed to be applied to the exposed interior surface (No. 4 surface) of an insulating glass unit (IGU).

Use in Moderate Climates

SUNGATE 600 can be applied to reduce heat loss while still allowing some heat gain and light transmittance into buildings, making it ideal for buildings in moderate climates or where heat gain is desired. With SUNGATE 600 applied to the No. 3 surface of a 1-inch IGU, PPG’s product data shows reduced heat loss with a U-value of 0.33, a solar heat gain coefficient (SHGC) of 0.65 and a visible light transmittance (VLT) of 71%.

Use in Cooler Climates

SUNGATE 600 can also be applied to increase insulating performance, without the need for triple glazings. This is ideal for buildings in colder climates or where higher insulating values are preferred. SUNGATE 600 on the No. 4 surface combined with a solar-control low-e like SOLARBAN 60 on the No. 2 surface of a 1-inch IGU (1/2-inch airspace) creates a 20% net gain in insulating performance with a U-value of 0.23.

PPG manufactures SUNGATE 600 using a pyrolytic process. While the glass is still molten, the coating is chemically bonded to the glass surface. This process creates a durable hard coat. The star-crystalline structure of the coating gives SUNGATE 600 a smoother surface than other pyrolytic glasses.
