PPG Introduces Optigray® and Solarban® z75 Glasses
One is a new super-neutral tint with a classic PPG name. The other is a
proven international success that is now launching in North America.
Together, Optigray and Solarban z75 glasses represent the two newest
additions to PPG’s ever-expanding collection of high-performance tinted and
solar control, low-e glasses.
Optigray Ultra-Neutral, Light-Gray Glass
The Optigray glass name may be familiar to many architects, engineers and
glazing professionals, but the new product it represents is bringing a
distinctly different aesthetic to the world of architectural glass.
With its warm-light-gray tint, Optigray glass is formulated to eliminate the
light-green color that is naturally present in conventional clear glasses,
producing a highly transparent, super-neutral glass that can actually show
less color than clear glass.
glass also delivers exceptional performance because it is engineered to
function as a substrate for solar control, low-e coatings on Solarban 60,
Solarban 70XL, Solarban 67 and Solarban R100 glasses. When Optigray glass is
paired with Solarban glasses in a standard 1-inch insulating glass unit, the
resulting configurations can produce visible light transmittance (VLT) of up
to 50 percent and solar heat gain coefficients (SHGCs) of as low as 0.24.
As part of PPG’s wide range of tinted float glasses, Optigray glass features
an appearance that is considerably lighter and more subtle than that of
Solargray® and Graylite® II glasses.
Solarban z75 Solar Control, Low-E Glass
PPG also recently debuted Solarban z75 glass in North America. Featuring a
neutral, cool-gray tint that is similar to popular Solarban z50 glass by
PPG, Solarban z75 glass offers architects and building owners an appealing
mix of daylighting, solar control and glare control.
As the table below demonstrates, these two products provide a range of solar
control performance options that can be fine-tuned to specific climates or
Solarban z75 glass (2) + Clear
Solarban z50 glass (2) + Clear
The low reflectance rate for both products also enables them to harmonize
well with other building materials, and with color-neutral, solar control,
low-e coated products such as Solarban 67, Solarban 70XL and Solarban R100
z75 and Solarban z50 Glasses Promote Sustainable Building
The center-of-glass insulating performance of Solarban z75 glass enables
most glazing designs to meet 2014 California Title 24 energy standards when
used as part of a well-designed and constructed glazing system.
In addition, Solarban z75 and Solarban z50 glasses can contribute to
achieving credit under LEED® v4 (and earlier versions) in the categories of
Energy and Atmosphere (EA), Materials and Resources (MR), Indoor
Environmental Quality (IEQ) and Innovation in Design (IN).
Solarban z75, Solarban z50 and Optigray glasses also are recognized by the
Cradle to Cradle Certified ProgramCM, joining numerous other PPG
architectural glass products. PPG offers more C2C-certified architectural
glass than any other float glass manufacturer.
