Heading into 2017, what is the biggest trend  
in designing with glass, and why?  
ow-iron glass is expanding in terms of its marketability and desirability. The  
thing architects like from glass is high light transmittance, and low-iron glass  
Lcan do that. The absolute clear quality of low-iron glass is a really attractive  
attribute, as architects like clarity. The challenge with that is the higher per-  
forming glasses are still not quite there yet in terms of meeting all the  
energy codes in the way we’d prefer. When I first started in selecting  
higher-performance glasses in the ’90s, you could get a solar heat gain  
coefficient (SHGC) of .29 or .28. It hasn’t come down much since.  
Reflectivity has gone up, as that’s the best way to meet  
that SHGC.

ith strong efforts to be environmentally conscious, many  
owners and investors show an increased interest in the  
products they are putting in their buildings, including glass.  
In 2017, glazing systems and products will continue to become more effi-  
cient. Additionally, with the increased development of automated devic-  
es and the ‘Internet of Things,’ these trends will only integrate further  
into commercial glass applications.

e’re always looking to use clearer glazing. The higher  
performance glass that has come into the market  
has made that more possible now than ever before,  
allowing for clearer glass while still being able to meet the  
ever-increasing requirements we need to meet from an energy  
standpoint. On top of that, we’re also incorporating more frit-  
ted vision glazing, which gets us even better performance by reducing heat gain while also  
allowing us to use more clear glass with less reflectivity. The ability of glass to be able  
to accomplish multiple things has allowed us to utilize it more.
