Exterior Applications of Acid etched Glass

Contrary to popular belief, acid-etched glass is not only suitable for interiors but can be readily used in exterior applications as well. This versatile translucent substrate is ideally suited to reduce glare, diffuse light, create depth, and provide privacy while maximizing daylighting. Combined with any low-e substrate in an insulated glass unit, acid-etched glass creates a brilliant and stunning energy-efficient glazing alternative.

Think Outside the Box... Acid-etched Glass in Exterior Applications

Contrary to popular belief, acid-etched glass is not only suitable for interiors but can be readily used in exterior applications as well. This versatile translucent substrate is ideally suited to reduce glare, diffuse light, create depth, and provide privacy while maximizing daylighting. Combined with any low-e substrate in an insulated glass unit, acid-etched glass creates a brilliant and stunning energy-efficient glazing alternative. The etched surface can be used on any of the four surfaces of an insulating glass unit, each providing a different and unique visual effect.

Because acid-etching is not a coating, its resistance properties in exterior conditions are essentially equivalent to unetched glass. Its unique closed-pore surface structure resists staining and allows for easy cleaning.

This building uses 6 mm Starphire® glass with the Textures Satin surface in position 1. Being in the Northeast, the glass is exposed to extreme weather conditions including heat and humidity in summer, snow and cold in winter and heavy rainfall in spring and autumn. In spite of this, the glass remains in excellent condition, years after installation, requiring minimal annual maintenance. The design intent in this project was to provide maximum light penetration into this section of the building while assuring privacy for the occupants.

Part of Wexford Science + Technology, the University City Science Center located in Philadelphia provides laboratory and office space to mid-sized biotechnology companies. Combining the need for privacy with the necessity for light transmission, all units are made with a panel of Starphire® glass with Textures Opaque finish in position 2. Vision areas have a Starphire® glass inside panel with a low-e coating in position 3, while spandrel units have an inside panel of clear glass with white ceramic frit in position 4. This project is LEED® Silver certified.

The Diana Center at Barnard College in New York, located on the corner of Broadway and West 120th was completely renovated in 2010. The design intent was to give the effect of brick without actually using it. To maximize the impact of Terracotta color on position 2, the architects opted for the ultra clear glass Starphire acid-etched Velour finish on position 1. The resulting glare reduction really brings out the color.

Clearly, acid-etched glass can be used effectively outside. These projects demonstrate the many advantages of this type of glass.    

Walker Textures® products offer a lot of flexibility to architects and designers providing unique functional and decorative solutions.    

So for your next project… Think outside the box.
