Glass for carbon-neutral buildings
PPG Industries has shipped its 20-millionth square foot of Solarban 70XL glass since it was introduced in 2006 as the world’s first triple-silver-coated, solar control low-E glass. Solarban 70XL glass is a high-performing environmental glass measured by its light-to-solar gain (LSG) ratio.
Solarban 70XL glass is the newest and highest-performing product in PPG’s residential glass portfolio that allow window manufacturers to provide premium, Energy Star-approved products that reduce heating and cooling costs for homeowners.
Scott Follett, director of new products and services for PPG Performance Glazings, says the clear-glass esthetics and environmental advantages associated with this glass product have made it popular among environmentally progressive architects. “Acceptance of Solarban 70XL glass is widespread and increasing around the world. We expect that trend to accelerate as sustainable building principles become part of international building design standards.”
To date, Solarban 70XL glass has been specified for thousands of buildings, encompassing projects with less than 1,000 square feet of glass as well as towering skyscrapers featuring hundreds of thousands of square feet of glass.
Due to a proprietary, triple-silver coating developed by PPG, Solarban 70XL glass transmits 64 per cent of the sun’s light in a standard one-inch insulating glass unit, while blocking 73 per cent of its heat energy, for a light-to-solar gain (LSG) ratio of 2.37.
The company says that according to independent energy-modelling studies, the glass can reduce annual cooling-related energy costs up to 13 per cent when it is specified instead of dual-pane tinted glass in a standard, window-walled, eight-storey office building. According to the same study, heating, ventilation and air-conditioning requirements in the same building are reduced up to 20 per cent, and carbon emissions are cut by nearly 500 tons a year.
Gary Danowski, vice-president, PPG Performance Glazings, says Solarban 70XL glass could play a critical role in the development of carbon-neutral buildings. “This product has become extremely popular for projects seeking to achieve LEED certification, including more than a dozen in just the last year,” he says. “Solarban 70XL glass is esthetically versatile and fulfills the industry’s desire for products that reduce reliance on fossil fuels and make buildings, safer, healthier and more enjoyable places to work and live well into the future.”

For energy savings and esthetics
The new ClimaGuard 75/68 low-E glass from Guardian Industries is made specifically for residential windows to provide unprecedented protection from the cold with superior insulation and clarity.
With energy costs and consumption growing concerns for many home-owners, having the right glass can address both issues.
ClimaGuard 75/68 low-E glass allows in 75 per cent of the sun’s natural light while also allowing in 68 per cent of the sun’s heat to warm homes naturally. Its U-value of .28 provides excellent insulation while maintaining high heat gain.
“Homeowners can increase energy savings with ClimaGuard 75/68 low-E glass,” says Scott Thomsen, chief technology officer for Guardian Industries. “It is raising the bar in residential glass and meets or exceeds Energy Star requirements in all northern zones.”
Homes in colder climates will benefit from ClimaGuard 75/68’s performance in extreme temperatures. It insulates 42 per cent better than double-clear glass, retaining heat and warmth to lower energy use.
The high-performance glass maintains a comfortable and consistent interior temperature. Coupled with the glass’s neutral appearance homeowners no longer have to choose between energy savings and esthetics.
ClimaGuard 75/68 joins Guardian’s complete line of high-performance low-E residential glass products that are designed for all climates throughout North America.
Architectural glass market
Last spring Guardian expanded its architectural product line with the introduction of Guardian CrystalGray, an innovative float glass substrate with a very light grey tint, ideal for a wide range of architectural glass markets.
In addition to an attractive neutral colour, Guardian CrystalGray has an improved light to solar gain ratio compared to standard blue and gray tinted float glass. The technology behind Guardian CrystalGray allows higher light transmission while reflecting infrared energy, thereby reducing the heat gain for many architectural applications.
This float glass in combination with coatings can help buildings achieve LEED (Leadership in Energy and Environmental Design) certification.
The company says CrystalGray was developed for the high-performance architectural glass market through “voice of the customer” research with Viracon, Inc., in Owatonna, Minn. Viracon offers Guardian CrystalGray as part of its specialty float glass product line that also includes Guardian UltraWhite low-iron float glass.
Like standard float glass, Guardian CrystalGray float glass can be used monolithically, tempered, laminated and fabricated. It can also be used on the exterior or interior lite of a vision insulated glass unit or in spandrel glass applications.

Optimal living comfort
AGC Flat Glass in Europe has launched a unique active coating for new-generation triple glazing called Planibel Tri.
This unique coating, specially designed for triple glazing assembly in residential applications, combines comfort and cost efficiency with an eco-friendly footprint. AGC says the coated glass saves up to 10 per cent of the annual energy consumption in residential applications. Its specially designed coating minimizes thermal loss with a very efficient U value and its high solar factor optimizes the free natural solar energy flowing through the glass, resulting in a very high energy savings.
