Pilkington Optitherm S1 Plus is the latest in its low-E range offering
ultra-low emissivity and achieving a U-value of only 1.0 W/m2K when
incorporated in a double glazed insulating glass unit.


Single stock low-E

Pilkington Optitherm S1 Plus is the latest in its low-E range offering ultra-low emissivity and achieving a U-value of only 1.0 W/m2K when incorporated in a double glazed insulating glass unit. Pilkington says it is the first and only single stock 1.0 U-value product currently available on the market. Optitherm S1 Plus combines superior light transmittance with a highly neutral colour.  It is suitable for any situation where excessive heat loss is a concern. Optitherm S1 Plus is always supplied as part of an IGU and due to its single stock characteristics can be used in annealed, toughened and laminated applications. The low U-value is confirmed in accordance with EN 673 tests. Ug values can go as low as 0.5 in triple IGUs. Optitherm offers an energy-efficient way to reduce heating bills and environmental impact through reduced CO2 emissions. it is suitable for both domestic and commercial applications including refurbishment and new builds. Optitherm is available in a range of sizes and thicknesses for various applications. Combine with Pilkington Optilam and Pilkington Optiphon for impact resistance, increased security or improved noise reduction.

Solarban for residences

PPG Industries has introduced Solarban 67 solar control, low-E glass for the residential market. Launched earlier this year for commercial building applications, Solarban 67 glass is formulated with a proprietary double-silver, magnetron-sputtered vacuum deposition (MSVD) coating that combines excellent solar control performance and a brilliantly clear neutral-glass appearance that reflects the true timbre and brightness of ambient light and colour. In a standard ¾-inch IGU with clear glass and a ½-inch air space, Solarban 67 glass provides visible light transmittance of 55 per cent and a solar heat gain coefficient of 0.29. Solarban 67 glass also has exterior reflectance of 19 per cent, which enhances its ability to reflect true-to-life colour, and interior reflectance of 16 per cent, which provides excellent outdoor views and a more comfortable living environment for homeowners. The winter nighttime U-value for Solarban 67 glass is 0.29.


Guardian ClimaGuard  

Designed for the north

Guardian Industries has launched two residential glass products to help customers meet and exceed energy standards in North America while providing optimal views and comfort to a home. Guardian ClimaGuard 72/57 was created for northern climates to take advantage of the sun’s natural light and heat.  This new low-E from Guardian incorporates a passive solar heat concept to selectively let warm sunshine into the home as a free and sustainable heat source while providing a powerful level of insulation against winter cold. ClimaGuard 72/57 has an uncommonly low U-factor, a neutral colour for outstanding esthetics and a high visible light transmission. ClimaGuard 72/57 allows many windows to meet the new Energy Star Version 6.0 criteria without a major redesign and without a fourth-surface coating. Plus, this new coating can be used on surface three of an IGU to meet northern zone criteria, or “flipped” to surface two to meet north central criteria.


Performance blue

Designers and architects have been searching for a new substrate that combines the attractive esthetics of a light blue-grey colour and the performance required for today’s code environment. In response, Viracon has introduced Graphite Blue, its newest substrate. With high levels of light transmission combined with low interior and exterior reflectivity, Graphite Blue is an appealing solution for many projects. Excellent solar control and reduced glare can be achieved when combined with one of Viracon’s high-performance low-E coatings. Graphite Blue can be incorporated into IGUs, laminated make-ups or used monolithically. Silk-screening or DigitalDistinctions by Viracon, a digital printing solution, can also be added to enhance the design. Graphite Blue can also be heat-treated and is available in 1/4-, 5/16- and 3/8-inch thicknesses to accommodate design specifications.

Bendheim is introducing Houdini Glass, a specialized decorative architectural glass delivering the benefits of both privacy and daylight. The low-iron, ultra-clear glass lets in maximum daylight, while its fine, micro-ribbed surface reduces glare and obscures the shapes of people and objects behind it. Houdini’s outstanding daylighting properties make it an ideal solution for any environment where privacy and natural light are vital, including health-care and educational facilities, laboratories, corporate offices, and retail applications. The glass offers a budget-friendly alternative to expensive or cumbersome mechanical daylight and privacy controls, such as louvres and laminated privacy films, as well as dust-collecting curtains and blinds. Its contemporary linear pattern and durability make it a timeless, versatile design element. “When industry professionals design for privacy and natural light, they often need to make a compromise,” said Donald Jayson, Sr. vice-president of Bendheim. “Design professionals can specify Houdini Glass for walls, partitions, screens and enclosures, doors and windows, ceilings, and balustrades. The naturally hygienic, non-porous glass surface easily withstands daily cleaning and sanitizing with most commercial cleaners, making Houdini Glass a great fit for high-traffic applications. Architects and designers seeking additional aesthetic options can specify Houdini Glass laminated to mirror, with coloured interlayers, or colour coated in a virtually unlimited palette. The mirrored Houdini Glass produces minimal reflections and disperses light to brighten interior spaces. Houdini Glass is available in tempered and laminated forms for additional safety. It is available in approx. 3/16-inch thickness in sheet sizes up to 65 by 126 inches.   


Traps the heat

Guardian Industries has introduced SunGuard Neutral 78/65, the newest addition to the SunGuard portfolio of low-E glass coatings. SunGuard Neutral 78/65 offers high visible light, a high solar heat gain and a neutral colour, and helps architects meet new energy codes in heating-dominated climates. Because SunGuard Neutral 78/65 lets the heat in, and keeps it in, the product is suitable for commercial applications in cooler climates where passive heat gain is desired. “We’re excited to offer this new solution to architects and builders looking at new construction and retrofits in the northern parts of the U.S. and Canada,” said Chris Dolan, director of commercial glass marketing. “Using SunGuard Neutral 78/65 can really maximize energy efficiencies in those environments.” Neutral 78/65 can be used in double- or triple-glazed units, and in combination with the SunGuard portfolio of high performance low-E coatings. The Guardian SunGuard product line includes low-E coatings and advanced glazings for commercial applications that offer excellent solar control and a wide variety of colours and performance levels.


Heat reflector

Viracon is pleased to introduce RoomSide low-E, a new interior surface coating designed to improve the U-value of a dual pane insulating glass unit by as much as 20 per cent. The coating works by reflecting indoor heat back into the room and improving thermal efficiency. Furthermore, a RoomSide low-E coating on the number four surface in combination with a high performance coating on the number two surface and an argon fill can offer comparable U-value performance to a triple insulating unit without the additional expense. When compared to similar products, RoomSide low-E is a highly durable coating with a smooth surface texture that makes it easier to clean. Standard cleaning solutions have been tested and are approved to use for routine cleaning purposes.
