Treating Glass as a Canvas

The right glass can add fantastic color fidelity to decorative treatments.

In the world of fine art, a master painter begins with canvas selection. A linen canvas is nearly always selected over cotton because nothing delivers the artist’s authentic vision quite like linen. 

Similarly, with glass. 

While it’s true glass manufacturers have made remarkable strides in recent years across a broad front, including energy efficiency, there remains major divisions in the way glass manufacturers approach clarity and light transmission.  

We’re talking, of course, about conventional clear glass and low-iron glass.  

Less Green, More Clarity 

The metaphor of cotton and linen canvas is apt in glass conversations. As good as today’s conventional “clear” glass is, it falls significantly short of low-iron glass’s highest potential clarity (87 percent less green tint) and generous 91 VLT (visible light transmission) rating.  

In fact, there is no industry standard specification criteria for “clear” glass, the clarity of which can vary broadly between batches and manufacturers.  

Small wonder low-iron glass is the glass of choice for interiors and exteriors across a wide array of iconic structures, including the Amazon SpheresBullitt CenterFallingwaterCalgary Central LibraryUCSD Jacobs Medical Center, among many other projects worldwide.

Historically, the purest low-iron glasses have been prized for their ability to step away from the limelight (literally, as it turns out) and showcase daylight and exterior views. “The clarity of the glass allows for it to appear invisible, a feature [Frank Lloyd] Wright admired,” explains Scott W. Perkins, director of preservation and collections for Fallingwater. Wright specified one of the industry’s pioneering low-iron glasses in his original specification for his iconic house.  

However, the extreme neutrality of low-iron glass is increasingly in demand for decorative interior design applications. Its minimal green and pure clarity provides a truly neutral substrate for dynamic patterns, colorful designs and more. 
 

Bernard Lax agrees. Lax, founder and head of Pulp Studio, a widely respected fabricator of decorative glass, says his team always specifies low-iron glass “… for projects where the aesthetic is the driving force to maintain color neutrality.”

Low-iron glass is increasingly specified for decorative features, doors and partitions, stairs and handrails, shower and bath enclosures, kitchens and backsplashes, security cases and displays, entrances and storefronts, and anywhere maximum color fidelity enhances artistry. Starphire Ultra-Clear® Glass by Vitro Architectural Glass is the design industry’s de facto low-iron standard, distinguished by its distinctive blue beveled edge and proprietary low-iron formula.

  1. Dichroic Glass. Dichroic is an effect that creates brilliant color shifts and movement within a single lite of glass. Effects can be enhanced by using textured glass as one or more of the lites or muted with acid-etching. Dichroic glass is known for its chameleon-like effects, where the glass’s transmitted and reflected colors can appear different.  
  2. Digital Ceramic Printing. An image is printed directly on glass. Virtually any full-color design is printable on low-iron glass.  
  3. Acid-Etched Glass. Offers a surface finish that diffuses transmitted light and reduces glare with a frosted appearance, often in a pattern. It is ideal for dividing walls, wall coverings, office partitions, shower and bath enclosures, floors, stairs and railings and doors. Acid-etching also is frequently used to create artistic patterns and in bird-friendly glass, which is increasingly in demand as many municipalities pass legislation requiring bird-friendly building design.  
  4. Ceramic Frit. A permanent, opaque coating that is fired into the glass, it offers pattern art ranging from simple shapes and gradients to intricate designs. Combine ceramic frit with coatings, tints, and reflected glass. Ceramic frit is frequently used in spandrel glass.  
  5. Other Applications. Polished edge glass and laminated glass with tinted or patterned polyvinyl butyral interlayers offer additional decorative options. 

When the project calls for a superior canvas of glass for dynamic design ideas, make low-iron glass a primary consideration. Request a sample of patented Starphire Ultra-Clear® Glass and experience the difference for yourself.

Mastering the higher ed campus building envelope

Building envelope choices for campus, cultural, and infrastructure projects are shaped by particular conditions. Today, institutions place greater value on how buildings relate to their ensemble: how historic buildings fit next to new ones, how massing forms fit with their neighbors, and how a building cladding contributes to the campus context. Concurrently, enclosure assemblies and construction methods have undergone changes due to values of sustainability, science, durability, and maintenance. In this context, mastering the building envelope on college and university campuses requires addressing both cultural concerns and technical performance, honoring traditional buildings while exploring the potential of new materials and forms.

True Clarity for Ambitious Design

Clear glass is extremely common and is popular for a variety of architectural design applications, including vision glass, spandrel glass, storefronts, entryways and other exterior uses. It is specified repeatedly due to its versatility and ability to serve as a substrate for solar control, low-emissivity (low-E) coatings. However, when specifying glass to achieve a desired aesthetic, design professionals know that clear glass isn’t completely clear.
