PPG Makes Plethora of Product Updates
Pittsburgh-based PPG Industries has announced several updates to its product lines.

The company’s Sungate® 400 glass has been approved for lamination with select interlayer and film materials, including Saflex® and Vanceva® from Solutia and Butacite® and SentryGlas® by DuPont. Sungate 400 is a passive, low-E glass with a magnetron sputtered vacuum deposition soft coat. Despite its clear aesthetic, Solarban 400 glass has a winter U-value that is 9 percent better than passive low-E glasses such as Sungate 500 glass manufactured with a hard pyrolitic coating.

Graylite® II glass, a nearly black glass, has been enhanced to provide better solar control performance than original Graylite glass. In a 1-inch insulating glass unit with clear glass, Graylite II glass has a solar heat gain coefficient of 0.21, or 36 percent greater than the original composition. It retains the aesthetic appearance of the original glass, but has slightly lower visible light transmittance of 8 percent.

The company also has published a new architectural glass catalog. The 36-page booklet contains detailed product descriptions for the company’s entire glass product line. The catalog is designed to complement the PPG architectural glass binder, which is now published online exclusively.

Pilkington Updates Its Energy Advantage™
Toledo, Ohio-based Pilkington says that the latest evolution of its Energy Advantage™ glass has increased its clarity, improving views and aesthetics, while maintaining the benefits of enhanced insulation and high solar heat gain. Energy Advantage delivers clarity and thermal insulation with the benefits of a pyrolytic low-E coated glass.

The latest product advancement reduces the haze value to a level so low that is difficult to perceive. It still has no off-angle color as found with common sputter coated glass products.

fire-rated glass
Unicel and TGP Team Up for Fire-Rated Privacy Solution
Longueuil, Québec-based Unicel Architectural’s patented Vision Control® louvers-in-glass is now available combined with Pilkington Pyrostop® glazing from Technical Glass Products (TGP) in Snoqualmie, Wash., the first such product assembly to achieve Underwriters Laboratories’ (UL) fire protection classification. Vision Control insulating glass units now incorporate glazing with fire-ratings of 45, 60 and 90 minutes.

The UL-classified Vision Control and Pilkington Pyrostop solution is intended to meet a demand for fire-rated privacy systems, particularly in healthcare environments. The combined glazing assembly has been UL fire-rated for doors, windows, transoms and sidelites.

framing systems
Kawneer Makes Ultra Thermal Addition to Impact-Resistant Framing
Kawneer Co. Inc., an Alcoa business based in Norcross, Ga., reports that with its IR501 Ultra Thermal (UT) framing system for single span storefronts and says it’s the only commercial manufacturer using a dual thermal break with an impact-resistant product to achieve enhanced thermal performance. The IR 501UT framing employs a “dual” IsoLock® thermal break, helping improve thermal performance without compromising structural performance and impact resistance.

Wasco Adds Smart Glazing to Its Line-Up
Wasco Skylight Products Inc. in Sanford, Maine, has introduced an electrochromic glass option into its portfolio of high-performance glazings.

The company is offering Sage Electrochromics Inc.’s SageGlass® glazing to help reduce glare and solar heat gain while maintaining a constant view of the outdoors. Varied opacity can be activated with a switch or integrated into a building management system. Visible light transmittance for SageGlass ranges from 62 percent in its clear state to 3.5 percent in its darkened state.

laminated glass
Viracon Introduces New High-Performance Laminated Glass
Viracon in Owatonna, Minn., has introduced a new sustainable high-performance coating developed exclusively for use with laminated glass. The new VLE-70 offers neutral aesthetics while reducing direct solar heat gain.

VLE-70 is a neutral coating that provides a visible light transmittance of 68 percent and a solar heat gain coefficient of 0.43 in a 9/16-inch clear laminated configuration. The coating’s high visible light transmittance provides an abundance of natural daylight while minimizing solar heat gain.

VLE-70 may be applied on clear glass and all other glass substrates. When incorporating VLE-70 with tinted glass, optimal performance is obtained when the tinted glass substrate is positioned as the interior ply of the laminate.

GANA, IWCA Release Joint Informational Bulletin
The Glass Association of North America (GANA) and the International Window Cleaning Association (IWCA) have released a joint glass informational bulletin (GIB), Construction Site Protection and Maintenance of Architectural Glass, outlining the need for proper protection of architectural glass throughout the construction process to all general contractors and builders. This protection includes various recommendations and the need for open communication and full cooperation among the general contractor, professional window cleaner and all trades involved.

A key component of the document emphasizes the need to use professional window cleaners and not someone inexperienced in the post construction cleaning of glass. The use of unskilled non-professionals can be a detriment to completing the construction job in the best possible way. Additionally, the general contractor or builder may need to schedule periodic glass cleaning during extended construction schedules so that the potential for glass damage is reduced. Suggestions such as these provide real-world solutions to prevent costly issues later, including the potential for contentious litigation.

UltraMirror Provides Scratch-Resistance
Guardian Industries in Auburn Hills, Mich., has a new mirror product for residential and commercial interiors that it says is more scratch-resistant than regular glass. DiamondGuard UltraMirror was designed to defend against the destructive elements that degrade a mirror’s reflectance and lifespan. On its back surface, the mirror coating is protected with a scratch-resistant UV-cured material that is permanent and durable. On its front surface, the company uses patented technology to deposit a diamond-like protective layer that is more than ten times more scratch resistant than ordinary glass. The end result is a mirror that resists scratching from items such as keys, silverware and other metal objects.

DiamondGuard UltraMirror can be cleaned with a wide range of common household products. It is available in thicknesses of 3- to 19-mm.
