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