Sungate® 400 Passive Low-E Glass
With its extensive background in multiple glass coating technologies, Vitro Architectural Glass (formerly PPG glass) has the ability to continually refine products to meet the needs of homeowners in a range of climates. Sungate® 400 glass is a superb example of that expertise.
Building on decades of proven technology and performance, Sungate® 400 passive low-e glass is engineered to meet Canadian ENERGY STAR® requirements, as well as the increasingly rigorous demands for energy-efficient windows in northern U.S. climates.
With a winter nighttime U-value of 0.28, Sungate® 400 glass helps homes trap winter furnace heat up to 41% more effectively than standard double-pane insulating glass units fabricated with clear glass. The same coating also cultivates a feeling of warmth and comfort in homes by allowing almost 70% of the sun’s heat energy to pass through, along with nearly 80% of the available daylight.
The benefits of Sungate® 400 glass remain when days get longer and warmer, too. In the spring and summer, Sungate® 400 glass continues to deliver lower energy costs by blocking solar heat and transmitting high levels of sunlight. That not only diminishes demand for air-conditioning, while also cutting the electricity bill for lighting.
For even greater year-round insulating performance, homeowners can insist on windows made with Sungate® 400 glass and Intercept® Warm-Edge Spacers by Vitro glass. With the industry’s highest thermal performance rating, Intercept® spacers deliver the added benefits of reduced heat transfer, less condensation and enhanced durability to protect your window investment for years to come.
