Solarban® z50 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® z50 glasses 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® z50 glass registers a SHGC of 0.32 and VLT of 51, producing an LSG ratio of 1.59. Consequently, Solarban® z50 glass is suited to climate zones that are more equally balanced between heating and cooling seasons.
With interior reflectance levels below 12 percent, Solarban® z50 by Vitro Glass provide building occupants with clear, natural outdoor views. Similarly, because of their neutral color, Solarban® z50 glasses harmonize well with other clear and color-neutral solar control, low-e glasses such as Solarban® 67 and Solarban® R100 glasses.
Solarban® z50 by Vitro Glass 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.
