More about this product

Starphire® Ultra-Clear™ glass by Vitro Architectural Glass can transform heavy glass applications by adding sparkling clarity and color fidelity compared to standard clear glass. Vitro Glass makes Starphire® Ultra-Clear™ glass in a variety of thicknesses, from ¼-inch (6 mm) up to ¾-inch (19 mm). With its signature blue edge, it's an excellent choice for a wide range of extra-heavy glass applications, including:

  • Entrances and Storefronts: Starphire® Ultra-Clear™ glass provides maximum brightness for entryways with 7 percent higher visible light transmittance (VLT) than ordinary clear glass (in ½-inch glass thickness).
  • Safety and Security Glass: Starphire® Ultra-Clear™ glass safety and security glass provides 16 percent higher visible light transmittance (VLT) than ordinary clear glass in a 13/8-inch laminated glass construction, and it can be fabricated easily to exact specifications.
  • Spiderwalls and Skylights: Starphire® Ultra-Clear™ glass provides sparkling clarity and undistorted transmission of color, without the greening and distortion of conventional clear glass, particularly as thickness increases.
  • Interior Glass: Starphire®Ultra-Clear™ glass can also be used for shelves, showcases, tabletops, back splashes, doors, side lites, decorative panels, clerestories and partitions
  • Balustrades: Vitro glass is a marketing alliance partner with Walker Glass in offering the Walker Textures® line of acid-etched glass and mirrors made with Starphire® Ultra-Clear™ glass. This glass is ideal for use with acid-etched glass products because of its clarity and color fidelity, especially for interior partitions.
  • Bath Enclosures: Starphire® Ultra-Clear™ glass is an excellent choice for shower and bathtub enclosures using Clarvista™ glass, a factory-fused, transparent coating that protects new shower glass against dullness caused over time by the corrosive effects of heat and humidity.

Architects commonly specify Vitro Architectural Glass products to meet LEED® and other green building criteria. Vitro Glass has been a pioneer in oxygen-fueled glass furnace technology, which cuts natural gas consumption by 15 percent compared to conventional air-fired glass furnaces, while reducing carbon emissions by 10 percent and nitrogen oxide emissions by more than 50 percent, operating one-third of the world’s oxygen-fueled glass furnaces.

The company promotes sustainability through post-consumer recycling of its products, by meeting global regulatory statutes and by developing wildlife-friendly products such as the industry’s first “bird-safe” low-emissivity (low-e) glass, and “turtle glass,” which helps turtle hatchlings survive in commercially developed coastal areas.
