Protecting your Calgary windows with Solarban and Sungate glass

By the A two Z Windows & Doors Team and JELD-WEN Canada

One may think that living in Alberta that solar control in your windows would never be an issue, but the harsh truth is the hot prairie sun can create a lot of damage to your walls, furniture and flooring in winter and summer. The best way to protect the interior of your home is to invest in glass windows and doors that have low-e, transparent finishes from A two Z Windows & Doors Calgary.

According to PPE, the manufacturer of Solarban  and Sungate, which has pioneered the glass technology found in the world’s best windows, the following details can help you determine the best finish for your new Calgary windows :

Solarban 67 glass, the latest addition to the Solarban family of products, is made with a soft, virtually imperceptible, neutral coating that lets your windows accurately reflect exterior light and color, while presenting a crisp, clear outdoor appearance. In the summer, it blocks more than 70 percent of the sun’s radiant heat energy when used in a standard ¾-inch, dual-pane residential window. In the winter, excellent insulating performance – signified by U-value of 0.25 –helps trap furnace heat. Combined, this performance contributes to year-round energy savings.

As an added bonus, Solarban 67 glass has a Tdw-ISO rating* of 0.41. That means, compared to standard dual-pane windows with clear glass, Solarban 67 glass cuts the risk of fading damage to your furnishings, fabrics and carpeting by nearly half. If you want the look of brilliantly clear windows that flood your home with natural light, reduce its seasonal cooling and heating demands and protects its most colorful treasures from sun damage, ask for Solarban 67 glass by PPG.


The optional Solorban 60 Low-E glass is a value-added product that brings energy savings and comfort to your home.

PPG Solarban 60 Solar Control Low-E glass is engineered to provide year-round comfort, keeping your home cooler in the summer by keeping out solar heat and warmer in the winter by keeping furnace heat inside.

PPG Solarban 60 Low-E glass helps your home become more energy efficient and comfortable thanks to an almost invisible, microscopically thin coating that blocks out unwanted solar energy and keeps in furnace heat. Additionally, Solarban 60 Low-E significantly reduces the fabric fading effects of ultraviolet light and resists condensation and its effects on your home environment.

With its ability to block 62% of total solar energy while allowing 70 percent of visible light to pass through, PPG’s Solarban 60 glass can help you achieve a building design that provides year-round comfort with heating and cooling cost savings.  In addition to functioning as a clear glass, Solarban 60 glass also can be combined in insulating glass units (IGUs) with an outboard lite of PPG tinted or reflective-tinted glass to increase aesthetic and performance options.

Solarban 60 Starphire glass can help you achieve your design vision of a glass building with the ultimate in transparency and visual clarity combined with energy efficiency. Solarban 60 Starphire glass allows ultra-clear glass to be used for vision glass, skylights, atriums, storefronts and entryways without sacrificing energy performance. Used in a 1-inch IGU, Solarban 60 Starphire glass provides high visible light transmittance (74 percent) while offering superior solar control (0.40 solar heat gain coefficient).

For detailed performance data, please review the Solarban 60 glass product data sheet or the Solarban 60 Starphire glass product data sheet.

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 per cent 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.
