What’s All the Talk About Clearer Fire-rated Glass?

A few years back, design professionals started asking fire-rated glazing manufacturers and suppliers to further enhance the aesthetics of fire-rated glass.  In response, some manufacturers and suppliers (disclaimer: yes, this includes TGP) went back to the drawing board to reconfigure processing methods.  How can we reduce the color in fire-rated ceramic glass?  Can we reduce surface imperfections formed during glass production?   The result of all these questions? Answers. Fire-rated glazing options are now available that are better able to meet both design and life safety requirements. As is true in every industry, some manufacturing processes yield better results than others.  But the bottom line is there is no reason to use fire-rated glass that forces a compromise on aesthetics.   So, how can you tell if the fire-rated glass you’re using is clear, particularly if the manufacturer or supplier says they’ve improved the optical quality?  Beyond basic due diligence research, there are a few practical things you can do. Request a large-size glass sample Small glass samples don’t provide an accurate representation of visible color or surface quality.  Depending on glass type, the color may be more – or less apparent – than it would be in an actual end-use application.  If a manufacturers’ standard sample size offering is too small for your comfort, request a larger sample.  If they won’t comply, it might be a good idea to walk away. View glass against various backdrops It’s best to inspect glass color against a range of backdrops.  Background color schemes either emphasize or minimize glass tints and hues, so where possible, evaluate glass color against a backdrop similar to that of the intended application. View glass in direct and indirect sunlight Make sure you view fire-rated glass in a setting similar to that of your intended application.  To use the diamond analogy, diamonds often appear darker in direct sunlight (though they will sparkle more), but clearer in soft light.  The same holds true for glass.   Compare glass samples Compare the glass sample to other glazing you intend to use in the building, as well as to other potential fire-rated glass candidates.  Each type of fire-rated glass has different aesthetic qualities.  Neighboring materials might complement these features or, conversely, make them more visible.
