Salesforce Transit Center
Architects Pelli Clarke Pelli specified the most demanding requirements for a fire-rated glass floor and skylight to date for this project including 2-hour fire rating, blast, and seismic resistance, live loading for foot traffic, and waterproofing.
Vetrotech and Greenlite Glass Systems Inc. produced and rigorously tested an innovative solution involving horizontal fire-rated glass, structural glass, and spacers with airgaps to avoid replacing glass due to dirt and condensation issues that would develop with foot traffic and the outdoor environment.
CONTRAFLAM LITEFLAM-XT-120 system – a walkable fire-rated glass floor and skylight was created specifically for the transit center. As the only exterior multi-panel system to pass all of the tests and comply with the specifications, CONTRAFLAM LITEFLAM-XT-120 allows the light columns to flood the Grand Hall with natural light.

"Greenlite Glass Systems Inc. was approached by Pelli Clark Pelli Architects in 2008 to assist them with their vision of “Light Columns”, which bring natural light from the main level down to the grand entrance. Our LITEFLAM fire-rated glass floor system was the only solution at the time – but I knew the project specifications and new challenges where going to be a feat of modern glass technology that only VETROTECH could help us solve."
