Originally, a 1.52 mm thick PVB interlayer was the material they were going to use, but after comparing this with SentryGlas® 0.9 mm thick interlayer, they decided to use the latter, primarily because the thickness of the glass gave better safety performance, weight, stiffness and clarity. SentryGlas® was used in the platform and facades of the subway.
Carlos MacGregor, designer of all subway lines in Mexico City, commented:
"The excellent rigidity and safety performance of DuPont™ SentryGlas® convinced us that it was the most suitable material for protecting the passengers on this project."
This is reflective of DuPont's commitment to working with business and governments to create a safer world for people to live in.
