More about this product

Solarban® z75 solar control, low-e glasses by Vitro Glass provide a steel blue-gray appearance with high levels of visible light transmittance. The coatings are tuned to provide different levels of solar control performance, enabling architects to specify the optimal choice for local climate and building code demands.


Neutral, cool-gray Solarban® z75 by , excel at controlling glare while offering superior daylighting and solar control properties to support sustainable design. The result is a product that complements a wide range of design scenarios with visible light transmittance (VLT) and solar heat gain coefficients (SHGC) that are as good as or better than competing architectural glasses with the same aesthetic. In a standard 1-inch insulating glass unit (IGU) with clear glass, Solarban® z75 glass has a SHGC of 0.24 and VLT of 48 percent, which combine to yield a light to solar gain (LSG) ratio of 2.00. These exceptional solar control characteristics make Solarban® z75 glass an excellent choice for warmer climate zones with high air-conditioning demands.

With interior reflectance levels below 12 percent, Solarban® z75 by Vitro Glass provide building occupants with clear, natural outdoor views. Similarly, because of their neutral color, Solarban® z75 glasses harmonize well with other clear and color-neutral solar control, low-e glasses such as Solarban® 67 and Solarban® R100 glasses.

The center-of-glass insulating performance of Solarban® z75 by Vitro 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 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) as detailed below.
